Product information "EXPLORE SCIENTIFIC 2" UHC Nebula Filter"

One of the most important obstacles for the exploration of the night sky is the brightening of the night sky by artificial lights, such as streetlights. The night sky is not really dark in the vicinity of towns or cities, which reduces the visibility of objects beyond the solar system enormously. Depending on the type of the celestial object, it is possible to dramatically increase the contrast by blocking annoying artificial light. The EXPLORE SCIENTIFIC UHC filter "zeros in" on the wavelengths of so-called emission nebulae. Those objects glow in special colours - their emission lines. Those emission lines are linked to chemical elements - in this case hydrogen at 486nm and 656nm, plus oxygen at 496nm and 501nm. The EXPLORE SCIENTIFIC UHC nebula filter blocks all other colour wavelengths (and thereby nearly all of artificial light) and only the emission line of the hydrogen and oxygen can pass the filter. The result is astonishing: suddenly nebulae are visible at locations that were completely invisible from, without filters. In suburban skies, for example the Owl-nebula M97, the Veil-nebula NGC 6992 or even the bright Dumbell-nebula M27 are not clearly visible. Using this filter allows you to see nebulae and their structures in much finer detail. A must for every visual observer. The Explore Scientific nebula filters come with a individual test certificate - your guarantee to receive a premium filter.

EXPLORE SCIENTIFIC 2" CLS Nebula Filter

Besides air turbulence, the brightening of the night sky is the biggest obstacle to observing faint objects beyond the solar system. Street lamps and other artificial lighting mean that the sky in human settlements is no longer really black. This affects the contrast and thus the perception of deep-sky objects. Depending on the type of celestial object, however, part of disturbing artificial light can be filtered out, making it easier to observe fainter targets.The EXPLORE SCIENTIFIC CITY LIGHT SUPRESSION - or CLS - filter uses the fact that the artificial lighting is not evenly distributed over the entire spectrum. These colours - in the case of the EXPLORE SCIENTIFIC CLS nebula filter, above all the typical colours of mercury and high-pressure lamps, used in street lighting - are suppressed, but the emissions of deep-sky objects are allowed through. With a slightly brightened sky, some relatively bright deep-sky objects are practically invisible with a telescope, for example the large galaxy M101. Using this filter makes observation much easier. A must have for any visual amateur astronomer. The CLS can also be used as a useful photographic filter - helping to improve the quality of your telescopic deep sky photos.The EXPLORE SCIENTIFIC nebula filters are delivered with an individual test report - so you can be sure of receiving high-quality filters.SPECIFICATIONS:eliminates disturbing light - e.g. from street lightingenables observation of faint deep sky objectsWHAT'S INCLUDED:1x nebula filter

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

BRESSER HD Moon & Planetary Camera & Guider 1.25"

Enter the world of astrophotography now. With the new BRESSER HD moon and planet camera with ST4 autoguider function. This camera is very good for astrophotography with short exposure times, i.e. for celestial objects like the moon, planets or star clusters. For astrophotography with long exposure times for low light deep sky objects, like galaxies and gas nebulae, we recommend the BRESSER Full HD Deep-Sky Camera (Art. No. 4959050) instead, with it's even higher resolution and sensor sensitivity. Equipped with the new high-sensitivity SONY IMX225 CMOS colour sensor, the BRESSER HD moon and planet camera delivers amazing image results with very short exposure times, even with simple telescope equipment. In addition, this ultra-modern camera can also be used as an autoguider, e.g. to actively track the main imaging device with SLR or CCD astro camera. A universal CMOS colour camera that delivers super-sharp lunar and planetary images in particular. The particularly low noise level of this new chip generation from SONY, ensures an exceptionally high brilliance and no cooling is required. Due to the high native pixel resolution of 1280x980, together with suitable telescopes, very beautiful images of the moon, but also detailed planetary images are possible. The ToupSky pro software included in the scope of delivery not only offers the necessary basic functions for image and video recording, but also many helpful special functions for image post-processing and for setting up the Guider. Functions such as live image display, exposure settings, white balance, dark image capture, stacking, timelapse recordings and much more can be individually configured. Especially the very sophisticated software makes it really easy for you to get started in astrophotography. With the automatic settings, you can produce absolutely presentable results without much prior knowledge. If you wish, simply switch off the automatic settings and gradually venture into the individual professional settings. Connect the camera directly to the ST4 connector of your telescope mount and you have fully automatic tracking control. This makes long exposures of several minutes possible without the stars producing unwanted line marks due to the ever-present synchronisation fluctuations of a telescope mount. A corresponding ST-4 connection cable is even included with the camera. Due to the high light sensitivity of the camera, you will always find a suitable guide star even with very short exposure times. For connection to guide tubes or off-axis guiders, the camera has a 1.25" plug-in sleeve, 1.25" filter thread (M28.5x0.6) and C-mount 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).

EXPLORE SCIENTIFIC Dark-Sky Filter 77mm Slim

Universal Dark-Sky Filter with 77mm thread for photo lens. Contrast enhancing filter for Aurora- and Deep-Sky imaging. Especially during Aurora imaging the most important wavelength of 550nm (green) and 630nm (red) this filter let pass by 90%. In comparrision to CLS filters, the Explore Scientific Dark-Sky Filter is blocking also the yellow Sodium (Na) wave at 590nm which elliminates Sodium-lamp street illumination from your picture. This is very useful because the yellow light is always a partially mix of green and red light. Removing the yellow wave-length with any image processing software will always damping also the green and red coloring. For Aurory imaging this is of course not wanted. At these days of increasing light pollution, the Explore Scientific Dark-Sky Filter is absolutely recommended in order to take pictures also from urban conditions.

Connection options The BRESSER power station can be used to simultaneously charge up to four mobile devices via USB, such as phones, MP3 players, games consoles, cameras, and drones. The device is equipped with two USB-C ports and two USB-A fast charging ports that support Qualcomm Quick Charge 3.0. You can also power up to four 12 V devices with a total power consumption of 10 A via the direct car cigarette lighter socket and the three DC 2.1/5.5-mm sockets. The power station comes with two 5.5/2.1-mm coaxial connector to cigarette lighter adapters, which can be used to connect car/camping devices such as cool boxes, water pumps, mini compressors, and air pumps directly or in parallel. The device is also equipped with two sockets with 230 V and 600 W total continuous output, which is ideal for connecting laptop/tablet/smartphone chargers, cool boxes, and musical instruments, or other electrical devices in this power class. Powerful built-in lithium-ion battery The powerful 576-Wh 40-Ah/14.4-V lithium-ion battery stores energy reliably and can be charged in just 6 hours with the supplied 230 V charger or 12 hours with the supplied 12 V car battery charging cable. In addition, thanks to the built-in solar charging regulator, you can also charge the power station directly via a suitable solar panel (not included). A clear display shows you all the information you need, including the battery charge level, battery charging progress, current consumption and charging power in watts, and the remaining operating time. Operating times with application examples How many hours will the power station power your devices for? You can work out the approximate operating time using the following formula: (Approx.) duration = 576 Wh power station battery x 0.85 / device input power in Watts. Example: Laptop with 45 W input power: 576 Wh x 0.85 / 45 W = operating time in hours; 576 x 0.85 / 45 = approx. operating time of 11 hours. 5 W LED light: approx. 98 hours 10 W LED light: approx. 49 hours 30 W camping cool box: approx. 16 hours 45 W notebook: approx. 11 hours 60 W television: approx. 8 hours Smartphone: 60 full charges Tablet: 35 full charges Camera: 60 full charges Laptop: 6 full charges Comprehensive protection mechanism for all outputs: The power station is protected against short circuits, overvoltage, overcharging and deep discharge of the battery, and overheating.
