Product information "EXPLORE SCIENTIFIC 8x50 Finder and Guider Scope with Helical Focuser, 1.25inch and T2 connection"
Universal 50mm viewfinder and guide telescope with a focal length of 220mm
Excellent 8x50 viewfinder telescope with removable eyepiece unit and crosshairs with adjustable red illumination. The precise helical focuser and the 1.25 inch /31.7mm plug-in connection, as well as the T2 camera connection thread (M42x0.75mm), allow the autoguiding required for long time exposure to obtain a point-shaped star image. It can also be used as a mini travel telescope.

High quality 8x50 viewfinder telescope with adjustable crosshair illumination
Image sharpness and viewing characteristics lift this viewfinder well above the level of the usual 8x50 viewfinder scopes. The visible image is bright and crisply sharp. Furthermore, this viewfinder has a very large field of view (FOV) of 6.96 degrees. This makes finding and adjusting objects much easier. The existing scale markings (pitch=1 degree) on the crosshairs are a good reference for estimating distances, and the open centre markings also make it easier to centre objects precisely. All lens surfaces are protected against weathering by multi-coating and guarantee a bright viewfinder image due to the high light transmission values. The adjustable red LED illumination unit is powered by two LR41 coin batteries. The main lens and the crosshairs can be focused independently of each other, giving you perfect focus for your eyes.

Compact tracking unit for autoguiding
One of the main applications for this telescope is the so-called autoguiding. Here the usually larger photo-taking optics are actively corrected by a smaller guiding telescope with a second tracking camera. This means that the mechanical fluctuations in the tracking accuracy, which are present in all astronomical telescope mounts, are measured by the tracking camera and compensated accordingly. This is necessary in order to obtain a point-shaped star image on the astrophotos during long time exposures and to avoid unwanted star trails. For this purpose, the guiding telescope is inserted into the existing viewfinder shoe of the photo-taking optics and aligned parallel. If the existing viewfinder shoe is not compatible, a suitable viewfinder shoe is also included. With the 1.25 inch / 31,7mm plug connection at the rear end or via T2 thread connection (M42x0,75mm), a tracking camera can be mounted afterwards. This is held securely by a brass ring clamp and 3 clamping screws. Please note the required back focus for your tracking camera. The focal plane (backfocus) is approx. 22mm behind the T2 thread. The sensitive focusing on the guiding star is done by a large knurled wheel of the mechanically precise manufactured helical focuser. For easy reproduction of the point of focus, this has a white millimetre scale from 0 to 28mm, which is attached by laser engraving. After the tracking camera has been connected directly or via computer to the telescope mount and the necessary basic settings have been made, the first astrophotos with long time exposure can be taken.

Use as mini travel telescope
This viewfinder and guide telescope can also be used quite simply as a mini travel telescope. With the optional eyepieces, a magnification of 8x to 40x can be achieved. Nearly all eyepieces with a focal length of 5 to 26mm and 1.25 inch/31.7mm plug connection are suitable. Especially recommended are the EXPLORE SCIENTIFIC eyepieces of the 52 degree (Art. 02195xx) and 62 degree (02196xx) LER series. Note: Only straight view use is possible.

Metal viewfinder holder and viewfinder shoe

The mount of this viewfinder and guide telescope is completely made of aluminium and is a stable base. The viewfinder mount is suitable for many common types of telescopes, such as EXPLORE SCIENTIFIC, BRESSER MESSIER etc. If the existing viewfinder shoe is not compatible, a matching viewfinder shoe is also included. This can be attached to the telescopic tube by means of four M5 screws. The bore distances of the viewfinder shoe are 31.7mm on the longitudinal and transverse axis. The six large adjustment screws with non-slip knurling make it easy to align the viewfinder, even with clammy fingers. All adjusting and clamping screws have plastic tips that effectively prevent the viewfinder housing and viewfinder mount from being scratched.

BRESSER Full HD Deep-Sky Camera & Guider 1.25"
BRESSER Full HD Deep Sky Camera with autoguider: a great camera for different types of astrophotography and for autoguiding. Not only suitable for planets, but also for deep-sky objects such as galaxies, nebulae and star clusters. Dedicated ToupSky Astro Imaging software supports video preview, video recording, video processing, image capture and processing, dark field correction and raw data output. Easy to use, but with professional results. One of the main features of the new backlit SONY IMX290 CMOS sensor is its high light sensitivity, which makes it possible to detect deep-sky objects without active cooling. SONY has increased the quantum efficiency at 533 nm wavelength up to 77%, which is much better than other CMOS sensors have been able to achieve in the past. Connect this camera to a guidescope and attach the camera's built-in ST-4 port, directly to your telescope's equatorial mount guide port and autoguide - using many popular audioguiding programs (PHD, Guidedog and more). Autoguiding enables you to take accurate pictures with long exposure times of several minutes. Thanks to the extra light-sensitive camera, you now always have a suitable guide star to hand, even using short exposure times. An ST-4 protocol connection cable is also included. Simple automatic tracking at its best. You can use this camera with all guiding telescopes, or off-axis guiders that accept a 1.25 " tube, 1.25" filter thread (M28.5x0.6) or C-mount adapter thread (1 "x1 /32"). IMPORTANT NOTES: This is not a stand-alone guider camera. You always need a Windows 10/11 computer to take pictures and for autoguiding. The autoguider software is not included. You can use PHD2 Guiding, Guidedog, Metaguide, Guidemaster (freeware) or AstroArt, MaxIm DL (paid).

BRESSER T2 Extension Tube Set
Set of 5 extension tubes with T2 thread on both sides for exact distances and secure hold of cameras for astrophotography. Also comes with SC to T2 thread adapter.In astrophotography, most cameras are connected to a telescope via a T2 thread (M42x0.75), the most popular international standard. However, in many cases, T2 and T2-ring adapters for connecting telescope focusers to a camera are not sufficient, as specific distances must also be observed. This is especially important when using correctors, reducers or flatteners. This extension tube set, which consists of 5 mm, 7.5 mm, 10 mm, 15 mm and 30 mm tubes, will allow you to obtain almost any distance using the corresponding combination. Each tube has a T2 interior thread on one side and a T2 exterior thread on the other side.Most telescopes either include a T2 thread adapter, or the eyepiece can be used with a simple T2 thread adapter with a 2 plug-in diameter (item no. 0510365).However, Maksutov-Cassegrain, Schmidt-Cassegrain, ACF or RitcheyChrétien telescopes may use a so-called SC thread. To allow you to use this extension tube set with these telescopes, the set also includes an SD to T2 thread adapter.FEATURES5 T2 tubes with lengths from 5 mm to 30 mmCombination of tubes allows you to obtain distances of 5 mm to 67.5 mmFor exact camera distances in astrophotographyDELIVERY CONTENT5x T2 extension tubes (5/7.5/10/15/30 mm)1x SC to T2 thread adapter

Explore Scientific ReflexSight LED Finder
A new take on a classic design, superior to the usual red dot finder - which will fit many telescopes and larger binoculars.Explore Scientific ReflexSight™ LED projection viewfinder, uses proven functionality with versatility, while having enhanced performance features.Looking through this viewfinder shows multiple deep red target circles projected against the night sky.  Both eyes can be used for quick and easy star hopping, in order to target objects in your telescope. The big advantage is that you can see the entire night sky without magnification and not just a small section of the sky, as you would through a magnified finderscope.  This makes Goto aligning quick and easy and speeds up acquisition of targets.New "Multi-Dot" target circle pattern (in standard circle diameters of 4.0 degrees, 2.0 degrees and 0.5 degrees), prevents blocking of stars within the field of view.  Using the widths of the projected circles as reference points allows those users with non-goto telescopes to easily work out the location of non-visible targets, with reference to more easily visible stars.  The projection screen size is a generous 55 x 35 mm.Multiple mounting options. The Explore Scientific ReflexSight™ LED projection viewfinder's base fits standard "Vixen-style dovetail" finder bases, allowing the user to attach this finder to a wife array of commercially-available telescopes, without modifying the telescope itself. A ¼ inch x 20G threaded adapter (photo tripod thread) is built into the finder base, allowing the finder to be attached to a variety of telescopes, via piggyback camera adapters with a photo tripod threaded hole.Functional design and intuitive use: the smooth housing, with no sharp corners, prevents snagging. Easily accessible battery compartment, taking 2x standard AAA alkaline batteries (not included), which power the frugal LED illuminator. The low power consumption of the LED lighting ensures a long operating time. Large, continuously adjustable brightness control with knurled knob head can be easily operated with gloves. Click the rotary switch to turn off completely. Rear-facing, tool-free three-point parallax knurled collimation knobs, again, easy to operate even with gloved hands, ensure you are well locked-on to the main optical axis of your telescope. The projection screen is coated, to minimise annoying reflections and allow you to concentrate on the finder's target and the night sky behind it.  Comes complete with screen and optics cover. The extremely compact design allows mounting even on small, lightweight telescopes - truly a finder for all!FEATURESReflexSight LED projection finder with deep red target circles Standard circle diameters 4.0 degrees, 2.0 degrees and 0.5 degreesProjection screen size: 55 x 35 mmFits standard Vixen-style dovetail finder shoes There is also a ¼ inch x 20G female photo tripod thread in the base Can be mounted via piggyback camera adapters etc. Operates on standard AAA batteries (not included) Smooth housing with no sharp corners, prevents snagging Comes complete with optics and screen cover Compact design and easily accessible battery compartment Large, continuously adjustable brightness control with knurled knob Click switch to turn off completely Tool-free three-point collimation parallax adjustment with easily accessible knurled knobs Can also be mounted on small and light telescopes WHAT'S INCLUDEDReflexSight LED projection finder

EXPLORE SCIENTIFIC 10x60 Finder and Guider Scope with Helical Focuser, 1.25inch and T2 connection
Universal 60mm viewfinder and guide telescope with a focal length of 250mmExcellent 10x60 viewfinder telescope with removable eyepiece unit and crosshairs with adjustable red illumination. The larger aperture and focal length, provide an even brighter field of view and more accurate tracking due to the higher resolution. The precise helical focuser and the 1.25 inch /31.7mm plug-in connection, as well as the T2 camera connection thread (M42x0.75mm), allow the autoguiding required for long time exposure to obtain a point-shaped star image. It can also be used as a mini travel telescope.High quality 10x60 viewfinder telescope with adjustable crosshair illuminationImage sharpness and viewing characteristics lift this viewfinder well above the level of the usual 10x60 viewfinder scopes. The visible image is bright and crisply sharp. Furthermore, this viewfinder has a very large field of view (FOV) of 6.0 degrees. This makes finding and adjusting objects much easier. The existing scale markings (pitch=0.85 degree) on the crosshair are a good reference for estimating distances, and the open centre markings also make it easier to centre objects precisely. All lens surfaces are protected against weathering by multi-coating and guarantee a bright viewfinder image due to the high light transmission values. The adjustable red LED illumination unit is powered by two LR41 coin batteries. The main lens and the crosshairs can be focused independently of each other, giving you perfect focus for your eyes.Compact tracking unit for autoguidingOne of the main applications for this telescope is the so-called autoguiding. Here the usually larger photo-taking optics are actively corrected by a smaller guiding telescope with a second tracking camera. This means that the mechanical fluctuations in the tracking accuracy, which are present in all astronomical telescope mounts, are measured by the tracking camera and compensated accordingly. This is necessary in order to obtain a point-shaped star image on the astrophotos during long time exposures and to avoid unwanted star trails. For this purpose, the guiding telescope is inserted into the existing viewfinder shoe of the photo-taking optics and aligned parallel. If the existing viewfinder shoe is not compatible, a suitable viewfinder shoe is also included. With the 1.25 inch / 31,7mm plug connection at the rear end or via T2 thread connection (M42x0,75mm), a tracking camera can be mounted afterwards. This is held securely by a brass ring clamp and 3 clamping screws. Please note the required back focus for your tracking camera. The focal plane (backfocus) is approx. 22mm behind the T2 thread. The sensitive focusing on the guiding star is done by a large knurled wheel of the mechanically precise manufactured helical focuser. For easy reproduction of the point of focus, this has a white millimetre scale from 0 to 28mm, which is attached by laser engraving. After the tracking camera has been connected directly or via computer to the telescope mount and the necessary basic settings have been made, the first astrophotos with long time exposure can be taken.Use as mini travel telescopeThis viewfinder and guide telescope can also be used quite simply as a mini travel telescope. With the optional eyepieces, a magnification of 9x to 50x can be achieved. Nearly all eyepieces with a focal length of 5 to 26mm and 1.25 inch/31.7mm plug connection are suitable. Especially recommended are the EXPLORE SCIENTIFIC eyepieces of the 52 degree (Art. 02195xx) and 62 degree (02196xx) LER series. Note: Only straight view use is possible.Metal viewfinder holder and viewfinder shoeThe mount of this viewfinder and guide telescope is completely made of aluminium and is a stable base. The viewfinder mount is suitable for many common types of telescopes, such as EXPLORE SCIENTIFIC, BRESSER MESSIER etc. If the existing viewfinder shoe is not compatible, a matching viewfinder shoe is also included. This can be attached to the telescopic tube by means of four M5 screws. The bore distances of the viewfinder shoe are 31.7mm on the longitudinal and transverse axis. The six large adjustment screws with non-slip knurling make it easy to align the viewfinder, even with clammy fingers. All adjusting and clamping screws have plastic tips that effectively prevent the viewfinder housing and viewfinder mount from being scratched.FEATURESExcellent 10x60 viewfinder and guiding telescopeCan also be used as mini travel telescopePerfect image sharpness and good viewing comfortFMC Multi-coated lens surfacesLens focal length: 250mmMax. possible camera weight: 550gRemovable eyepiece/cross hair unitCamera connection via 1.25 inch / 31.7mm plug connection or T2 threadT2 thread: M42 x 0,75mmPrecise helical focuser for focusing the visible imageFocuser travel range: 28mmClose focus distance: 3 mLaser engraved millimetre scale from 0 to 28mm on the focuserFocal plane (backfocus) is approx. 22mm behind the T2 threadSeparate focusing of the crosshair at the eyepieceVery large field of view FOV of 6.0 degreesWith adjustable red cross-hair iillumination Scale markings crosshair with 0,85 degree graduationPower supply of illumination unit: coin battery type LR41 (2pcs)Brass ring clamp and 3 clamping screws on the 1.25 inch plug connectionWith optional eyepieces magnifications from 9x to 50x can be achievedSuitable are almost all eyepieces with 1.25 inch/31,7mm shaftMounting of the viewfinder telescope is completely made of aluminiumViewfinder mount with 6 large adjustment screws with knurled head for easy gripFinder shoe suitable for EXPLORE SCIENTIFIC, BRESSER MESSIER etc.Additionally a suitable viewfinder shoe is includedBore distances of the viewfinder shoe are 31.7mm on the longitudinal and transverse axisAdjusting and clamping screws have plastic tipsWHAT'S INCLUDED10x60 viewfinder/guiding telescopeEyepiece unit with crosshairCrosshair illumination unit incl. batteriesViewfinder holder with viewfinder shoeInstruction manual

EXPLORE SCIENTIFIC TELRAD Projection Finder Scope with base
The TELRAD viewfinder is a projection finder that can be installed on any telescope and makes it child's play to align the telescope with the starry sky.The TELRAD viewfinder is a practical alternative to classic optical viewfinders and illuminated red dot viewfinders. You can see the complete starry sky without magnification, and not just a small section as with a normal optical viewfinder. Against this background of the starry sky, three red luminous concentric rings are projected, with apparent diameters of 4 degrees, 2° and 0.5° in the sky. Move the telescope so that the object you are looking for is in the inner ring, and the telescope points in the right direction. Because the object you are looking for is inside the ring, it will not be irradiated like a normal illuminated red dot finder.The base of the TELRAD viewfinder is self-adhesive and can be mounted on all telescopic tubes from about 10cm diameter. The length of the base is about 18cm. This base remains on the telescopic tube, the TELRAD viewfinder itself can be removed or attached at any time by means of the attached quick coupling. The TELRAD is powered by two normal AA batteries (not included).There are star atlases, like the "Deep Sky Travel Atlas" from Oculum-Verlag, and planetarium programs for the PC, like the program "Stellarium", where the three rings of the TELRAD are already drawn or can be displayed around the interesting celestial objects. This makes finding these celestial objects a real walk.FEATURESTELRAD projection finderIlluminated rings of 4 degrees, 2° and 0.5° in the skySee the complete starry sky without magnificationEasy installation and useCan be installed on nearly every telescopesBase with quick release coupling included Powered by two AA batteries (not included) Very long battery life because of LED technologySCOPE OF DELIVERYTELRAD viewfinder with projector and battery compartment TELRAD base with quick-release coupling for the viewfinder Adhesive tape for attachment to telescope

Universal 60mm viewfinder and guide telescope with a focal length of 250mmExcellent 10x60 viewfinder telescope with removable eyepiece unit and crosshairs with adjustable red illumination. The larger aperture and focal length, provide an even brighter field of view and more accurate tracking due to the higher resolution. The precise helical focuser and the 1.25 inch /31.7mm plug-in connection, as well as the T2 camera connection thread (M42x0.75mm), allow the autoguiding required for long time exposure to obtain a point-shaped star image. It can also be used as a mini travel telescope.High quality 10x60 viewfinder telescope with adjustable crosshair illuminationImage sharpness and viewing characteristics lift this viewfinder well above the level of the usual 10x60 viewfinder scopes. The visible image is bright and crisply sharp. Furthermore, this viewfinder has a very large field of view (FOV) of 6.0 degrees. This makes finding and adjusting objects much easier. The existing scale markings (pitch=0.85 degree) on the crosshair are a good reference for estimating distances, and the open centre markings also make it easier to centre objects precisely. All lens surfaces are protected against weathering by multi-coating and guarantee a bright viewfinder image due to the high light transmission values. The adjustable red LED illumination unit is powered by two LR41 coin batteries. The main lens and the crosshairs can be focused independently of each other, giving you perfect focus for your eyes.Compact tracking unit for autoguidingOne of the main applications for this telescope is the so-called autoguiding. Here the usually larger photo-taking optics are actively corrected by a smaller guiding telescope with a second tracking camera. This means that the mechanical fluctuations in the tracking accuracy, which are present in all astronomical telescope mounts, are measured by the tracking camera and compensated accordingly. This is necessary in order to obtain a point-shaped star image on the astrophotos during long time exposures and to avoid unwanted star trails. For this purpose, the guiding telescope is inserted into the existing viewfinder shoe of the photo-taking optics and aligned parallel. If the existing viewfinder shoe is not compatible, a suitable viewfinder shoe is also included. With the 1.25 inch / 31,7mm plug connection at the rear end or via T2 thread connection (M42x0,75mm), a tracking camera can be mounted afterwards. This is held securely by a brass ring clamp and 3 clamping screws. Please note the required back focus for your tracking camera. The focal plane (backfocus) is approx. 22mm behind the T2 thread. The sensitive focusing on the guiding star is done by a large knurled wheel of the mechanically precise manufactured helical focuser. For easy reproduction of the point of focus, this has a white millimetre scale from 0 to 28mm, which is attached by laser engraving. After the tracking camera has been connected directly or via computer to the telescope mount and the necessary basic settings have been made, the first astrophotos with long time exposure can be taken.Use as mini travel telescopeThis viewfinder and guide telescope can also be used quite simply as a mini travel telescope. With the optional eyepieces, a magnification of 9x to 50x can be achieved. Nearly all eyepieces with a focal length of 5 to 26mm and 1.25 inch/31.7mm plug connection are suitable. Especially recommended are the EXPLORE SCIENTIFIC eyepieces of the 52 degree (Art. 02195xx) and 62 degree (02196xx) LER series. Note: Only straight view use is possible.Metal viewfinder holder and viewfinder shoeThe mount of this viewfinder and guide telescope is completely made of aluminium and is a stable base. The viewfinder mount is suitable for many common types of telescopes, such as EXPLORE SCIENTIFIC, BRESSER MESSIER etc. If the existing viewfinder shoe is not compatible, a matching viewfinder shoe is also included. This can be attached to the telescopic tube by means of four M5 screws. The bore distances of the viewfinder shoe are 31.7mm on the longitudinal and transverse axis. The six large adjustment screws with non-slip knurling make it easy to align the viewfinder, even with clammy fingers. All adjusting and clamping screws have plastic tips that effectively prevent the viewfinder housing and viewfinder mount from being scratched.FEATURESExcellent 10x60 viewfinder and guiding telescopeCan also be used as mini travel telescopePerfect image sharpness and good viewing comfortFMC Multi-coated lens surfacesLens focal length: 250mmMax. possible camera weight: 550gRemovable eyepiece/cross hair unitCamera connection via 1.25 inch / 31.7mm plug connection or T2 threadT2 thread: M42 x 0,75mmPrecise helical focuser for focusing the visible imageFocuser travel range: 28mmClose focus distance: 3 mLaser engraved millimetre scale from 0 to 28mm on the focuserFocal plane (backfocus) is approx. 22mm behind the T2 threadSeparate focusing of the crosshair at the eyepieceVery large field of view FOV of 6.0 degreesWith adjustable red cross-hair iillumination Scale markings crosshair with 0,85 degree graduationPower supply of illumination unit: coin battery type LR41 (2pcs)Brass ring clamp and 3 clamping screws on the 1.25 inch plug connectionWith optional eyepieces magnifications from 9x to 50x can be achievedSuitable are almost all eyepieces with 1.25 inch/31,7mm shaftMounting of the viewfinder telescope is completely made of aluminiumViewfinder mount with 6 large adjustment screws with knurled head for easy gripFinder shoe suitable for EXPLORE SCIENTIFIC, BRESSER MESSIER etc.Additionally a suitable viewfinder shoe is includedBore distances of the viewfinder shoe are 31.7mm on the longitudinal and transverse axisAdjusting and clamping screws have plastic tipsWHAT'S INCLUDED10x60 viewfinder/guiding telescopeEyepiece unit with crosshairCrosshair illumination unit incl. batteriesViewfinder holder with viewfinder shoeInstruction manual

EXPLORE SCIENTIFIC OPTOLONG 1,25'' L-eXtreme Deep-Sky Light Pollution Filter
L-eXtreme Filter for deep sky nebula photography from the city The relentless spread or urbanization and its associated light pollution have become a growing problem for all amateur astro photographers. The current solutions to the problem can be expensive and might include the purchase of a monochrome camera, several types of narrowband filters and a filter wheel. Especially with inexpensive but fast newtonian telescopes, double-lens ED refractors or even achromats, the L-eXtreme filters open up completely new possibilities for high-class astronomical images even from the light polluted city. CMOS cameras can deliver images like monochrome cameras. This new generation of filters makes it possible to take amazing astrophotos directly from the heavily light-polluted city with all its artificial light sources. The dual narrow bandpass for the wavelengths of O-III and H-Alpha and the almost complete attenuation of the interfering light sources of these new filters make this an ideal solution. L-eXtreme Description L-eXtreme is a two 7nm narrow bandpass filter which can be used with one-shot color cameras like DSLRs (digital SLR), color CMOS and monochrome CCD cameras. The convenience and cost-effectiveness of this filter allows amateurs to photograph rich emission nebulas, even in bright, heavily light-polluted skies. The L-eXtreme filter is the better choice for fast optical systems at a competitive price. It isolates the H-Alpha and Oxygen III nebula emission lines so that the contrast and signal-to-noise ratio between nebulae are maximized. The design of our L-eNhance filter is a technical innovation among filters. For people who live in heavily light-polluted areas or when the moon is out, the L-eXtreme is a very good choice. Main Use and Performance This new generation of filters makes it possible to take amazing astrophotos directly from the light-polluted city with all its artificial light sources. The narrow bandpass for the wavelengths of O-III and H-Alpha and the almost complete attenuation of the interfering light sources do not require very large or extremely expensive telescopes. No, especially with inexpensive but fast newtonian telescopes, double-lens ED refractors or even achromats, these filters open up completely new possibilities for high-class astronomical images. Furthermore, with these filters CMOS colour cameras can deliver an image quality that comes close to CCD monochrome cameras. WARNING: These nebula filters are not designed for sun observation. DO NOT LOOK AT THE SUN WITH THIS FILTER. You will go BLIND if you ignore this warning. Coating technology L-eXtreme has a multiple anti-reflective coating on the optical substrate. The L-eXtreme filter uses a precision coating based on ion deposition coating technology. This ensures durability and scratch resistance as well as stability on the CWL (central wavelength), which is not affected by temperature changes. Absolute precision and homogeneity of the coatings as well as maximum values for transmission in the passband and optical density in the off-band range are guaranteed for all filters.  FEATURESProfessional photographic filter for astronomyImproves deep sky emission nebula photography Best choice for extreme light pollution suppression For taking pictures also from highly light-polluted areas Dual-narrow-band filter with high transmission for O-III and H-Alpha linesDoes not require very large or extremely expensive telescopesExcellent results also with fast inexpensive newtonian telescopes, double-lens ED refractors or even achromatsL-eXtreme filter is the better choice for fast systems at a competitive priceCMOS colour cameras can deliver an image quality that comes close to CCD monochrome cameras Filter diameter: 1.25 inches / 31.7 mmConnecting thread: M28x0.6mmSelected optical glass material Spectrum: 300-1000nm Off-Band Blocking: > 99 % Surface Quality: 60/40 (Refer to MIL-O-13830) Fine-optically polished to ensure accurate 1/4 wavefront and highest parallelism over the both surfacesHigh transmission at major nebula emission lines (i.e. H-alpha 656nm and OIII 496nm&500nm)SCOPE OF DELIVERY L-eXtreme filter (1 pc) Dust protection box (1 pc)
