Product information "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.

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. FEATURES
- Professional photographic filter for astronomy
- Improves 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 lines
- Does not require very large or extremely expensive telescopes
- Excellent results also with fast inexpensive newtonian telescopes, double-lens ED refractors or even achromats
- L-eXtreme filter is the better choice for fast systems at a competitive price
- CMOS colour cameras can deliver an image quality that comes close to CCD monochrome cameras
- Filter diameter: 1.25 inches / 31.7 mm
- Connecting thread: M28x0.6mm
- Selected optical glass material
- Spectrum: 300-1000nm
- Off-Band Blocking: > 99 %
- Surface Quality: 60/40 (Refer to MIL-O-13830)

EXPLORE SCIENTIFIC Deep Sky Astro Camera 16MP
€1,099.00*
High resolution deep sky camera with large Panasonic CMOS sensor and active cooling. Enter the world of astrophotography now. With the new EXPLORE SCIENTIFIC DEEP SKY ASTRO camera you get a modern complete package for the comfortable shooting of astro photos and videos. Finally, an easy-to-use camera for capturing galaxies, star clusters, the moon and even planets with high resolution and low sensor noise. Thanks to the fast USB 3.0 computer interface, all image data is transferred within a few seconds. Long waiting times are now history. Simply connect the camera to your telescope using the T2 female thread (M42.0.75mm) or the supplied 2" (50.8mm) plug-in adapter and after installing the drivers and the included EXPLORE Capture recording and editing software, you are ready to take the first real astro photos with a highly specialized camera for your application. The EXPLORE Capture Pro software included in delivery not only offers the basic functions required for image and video capture, but also many helpful special functions for image post-processing and camera setup. Functions such as live image display, exposure settings, white balance, dark image print, stacking, timelapse recording and much more can be configured individually. Especially the very sophisticated software makes your entry into astrophotography really easy. With the automatic settings you can produce absolutely presentable results without any previous knowledge. If you like, simply switch off the automatic settings and gradually dare to adjust the individual professional settings. The new EXPLORE SCIENTIFIC DEEP SKY camera has a highly sensitive and very low-noise Panasonic CMOS sensor which is additionally cooled down to 40°C below ambient temperature by the two-stage thermoelectric cooling. In contrast to normal DSLR cameras, this guarantees much lower noise and fewer hot pixels in your shots.

Through the controlled setting of the desired camera temperature, the creation of dark frames under reproducible shooting conditions is possible at any time. The large-format CMOS sensor with 21.9mm diagonal also allows large image fields and simplifies the adjustment and centering of objects considerably. The camera has a built-in USB hub with 2 x USB2.0 ports at the rear. Connect your additional autoguider camera or motor focus etc. via a short USB cable and reduce the risk of cable spaghetti and cable breaks. Separate cable connections between your accessories and your computer are no longer necessary. A sturdy hard case for the camera plus accessories is also included. IMPORTANT NOTES: Don't get confused by the megapixel data and the contrary price structure. In the field of astronomy, the key criterion is not the sensor resolution but the maximum light sensitivity. The main goal is to capture as much light as possible in a short time.DOWNLOAD latest camera software and drivers see download folder "Manuals" or here: http://www.touptek.com/download/showdownload.php?lang=en&id=2

BRESSER Messier NT203s/800 Optical Tube
€609.00*
NEW – now including a high-quality aperture Solar-filter for safe observation of sunspots, eclipses and planet transits. Great telescope for night and solar observation.In the past few years the Bresser Newton telescopes have become the standard workhorse for Deep Sky astrophotography. We now proudly present the second generation of this telescope, the Bresser NT-203s/800 with Hexafoc and a fast parabolic main mirror. The Bresser NT-203s/800 f3.9 will deliver you deeper images due to its - compared to 8" f/5 systems - oversized primary mirror and therefore faster optical system with the same exposure time. The big 85 mm secondary prevents vignetting for optimal illumination The excellent 2.5" Hexafoc focuser also does not cause vignetting due to its large diameter and makes focussing a joy - the smoothness and shifting-free operation sets new standards in this price class. This groundbreaking focuser, tube rings with 44mm universal standard dovetail and camera mounting feature and a high-end finderscope with haircross and laser-engraved scale leave nothing to desire even for demanding astrophotographers. The NT-203s/800 Hexafoc has a classical tube construction with an aluminium tube. The focuser can be upgraded with a 10:1 reduction (part No. 0625720) without problems. Ready to use with the HR Coma Corrector (part No. 0510330) which eliminates coma, field-curvature and astigmatism.Please note: Reflector telescopes with optical design Newton are very good for astronomical observing at the starry night sky. But these telescopes are not well usable for observing landscape and nature during daylight. Therefore we suggest BRESSER refractor (lens) telescopes for landscape and nature observing.CHARCTERISTICS

Highly corrected 80mm air-spaced triplet apochromat (with three lenses) and aluminium tube and a 2.5" high-precision HEXAFOC focuser. Apochromats are the ultimate choice in small to medium sized telescopes:
the combination of compactness, transportability, very high image
contrast and sharpness together with the possibility to make excellent
astrophotos cannot be bested. The advances in glass manufacturing during
the last few years have made true apochromats available to more
astronomy enthusiasts than ever before. The new Explore Scientific
FCD-100 Alu Hex
represents another major improvement in this field - the overall
correction (color and spherical) is setting new standards in this price
class. The optical design shows a polystrehl value of 0,97 indicating a
level of correction that is absolutely top of the line.This small
excellent apochromat is a very versatile telescope: the fast f-ratio
makes short exposure times possible. The high contrast and sharpness of
the image provide breathtaking views of large objects like the North
america nebula or the Andromeda galaxy as well as tack sharp planetary
images. The telescope is lightweight and compact - the dew shield slides
down the tube to minimize size for transportation. Revolutionary glass and precision
manufacturing created a telescope that offers observing joy on the
highest level. This does not only qualify this telescope as the ideal
travel scope, it is also the perfect choice for fast observations and
for astrophotography. The excellent 2,5" HEXAFOC focuser with 10:1 reduction is
perfect for this - the large inner diameter of 65mm prevents vignetting

Maksutov Newton MN-152 David H. Levy Comet Hunter Telescope
Highly corrected optic for wide-field observation and astrophotography. Developed in collaboration with the famous "comet hunter" David H. Levy. The Maksutov-Newton system does have some pros and cons respectively to the classical newtonian design. Apart from the higher price the main disadvantage is the higher weight - the thick corrector lens at the front is the cause for this. The main advantage of the Maksutov-Newton compared to the classical newton is the sharpness of the field of view. Classical newtonian telescopes do show a sharp pinpoint star image only at the middle of the field of view - outside the optical axis they have a dominant abberation, the so called coma. This is inherent in the newtonian design, and therefore valid for all newtonian telescopes of all brands and not caused by manufacturing tolerances. Coma distorts the star image - the pinpoint star shows a tail, just like a small comet. This decreases sharpness and contrast considerably. The Maksutov-Newton shows a much sharper star image - for most applications the coma is not visible. This results in a high contrast image all over the field of view - for visual observations and for astrophotography with DSLRs alike. This makes the Maksutov-Newton a ideal all-purpose telescope, that is able to show a sharp field without the need for additional correctors.

(37.74% saved)
Apart from air turbulence, the brightening of the night sky is the greatest
barrier to observing faint objects beyond the solar system. Due to
streetlamps and other artificial lighting the sky in urban areas is no
longer properly black. As a result, the contrast and thus the
perception of deep-sky objects also suffer. However, depending on the
type of celestial object, it is possible to filter out some of the interfering light making it easier to photograph the objects.The EXPLORE SCIENTIFIC H-Alpha filter uses the characteristic of the so-called emission nebulae.
These objects glow in certain colors, the so-called emission lines. The
emission lines are associated with certain chemical elements - in this
case the red glowing hydrogen. This filter blocks all other colors (and therefore almost all artificial light) and lets only the emission lines of hydrogen through. Especially the disturbing light of mercury and sodium vapor lamps is effectively blocked. The effect is amazing: Suddenly, nebulae become visible on the photos in places which appear completely empty without the filter.The EXPLORE SCIENTIFIC H-Alpha Nebula Filter has been developed exclusively for astrophotography. Especially in heavy light-polluted skies many emission nebulae are only visible and shown in full expanse on astrophotos when using this filter. The H-Alpha nebula filters make astrophotography near the city possible and the use leads to amazingly good image results despite the existing light pollution. A must for every urban astrophotographer.The EXPLORE SCIENTIFIC nebula filters are delivered with an individual test report - so you can be sure to get high quality filters.This filter's narrow passband of only 7 nm bandwidth works out

L-eNhance Filter for deep sky nebula photography from the cityThe
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 newtonian telescopes,
double-lens ED refractors or even achromats, the L-eNhance filters open up
completely new possibilities for the capture of high-class astronomical
images even out of 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 light-polluted
city with all its artificial light sources. The narrow bandpass for the
wavelengths of O-III, H-Beta and H-Alpha and the almost complete
attenuation of the interfering light sources of these new filters make
this an ideal solution.
L-eNhance Description L-eNhance provides an
economical and practical solution for amateurs. It is a tri-band pass
filter which has been designed for DSLR (digital SLR), color CMOS and
monochrome CCD cameras. The convenience and cost-effectiveness of this
filter allows amateurs to take a rich selection of astronomical images,
even in bright, heavily light-polluted areas. We believe the
design of our L-eNhance filter is a technical innovation among filters.
It effectively isolates the H-Alpha, H-Beta, and Oxygen III nebula
emission lines and achieves a maximum transmission of up to 90%. The
performance of this filter delivers images that superbly control the
impact from light polluted skies. Main Use and PerformanceThis
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, H-Beta 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 newtonian telescopes, double-lens ED
refractors or even achromats, these filters open up completely new
possibilities for high-class astronomical images.
Furthermore, with the help of 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-eNhance has a multiple
anti-reflective coating on the optical substrate. The L-eNhance filter uses a
precision coating based on ion deposition coating technology. This

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.

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.
Finally the slim housing design enables its use also with wide-field photo lens and doesn´t cause any vignetting.

One of the most important obstacles for the exploration of the night sky
is the brightening of the night sky by artificial lighting, 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 celestial object, it is
possible to increase the contrast dramatically by blocking the interfering artificial light. The EXPLORE SCIENTIFIC S-II filter uses the property of the so-called emission nebulae. These objects glow in certain colors, the so-called emission lines. The emission lines are associated with certain chemical elements - in this case ionized sulfur. The EXPLORE SCIENTIFIC S-II nebula filter blocks all other colors (and thus almost all artificial light) and lets only the emission lines of ionized sulfur at 672 nm through. The effect is amazing: suddenly, nebulae become visible in places that appear completely empty without the filter. In slightly brightened skies, many planetary nebulae, emission nebulae and supernova remnants can be seen without any difficulties using this filter. A must for every visual observer and for astrophotography.EXPLORE SCIENTIFIC nebula filters come with an individual test report - so you can be sure to get high quality filters.FEATURESSimplifies the observation of planetary nebulae, emission nebulae and supernova remnantsBlocks almost all artificial lightOnly lets the emission lines of ionized sulfur at 672 nm pass Transmission bandwidth: 12 nmAllows for more contrast in faint deep sky objectsIdeal for use near cities, in slightly brightened skiesIndividual test certificate included to guarantee you receive a premium filterSCOPE OF DELIVERY1x 2'' S-II nebula filter
