Product information "EXPLORE SCIENTIFIC OPTOLONG 1.25'' L-eNhance Deep-Sky Light Pollution Filter"
L-eNhance 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 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 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, 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 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.

EXPLORE SCIENTIFIC Deep Sky Astro Camera 16MP
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. The images are not only much sharper and more brilliant, but also contain more usable image information. 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 Sample photos made by Lóránd Fényes in Hungary: https://fenyeslorand.hu/asztrofotok/Field of view for different focal lengths in arc minutes and degrees: 400 mm - 151´x 114´ (2.5 x 1.9 degrees) 500 mm - 121´x 91´ (2.0 x 1.5 degrees) 600 mm - 101´x 76´ (1.7 x 1.3 degrees) 700 mm - 86´x 65´ (1.4 x 1.1 degrees) 800 mm - 76´x 57´ (1.3 x 0.9 degrees) 900 mm - 67´x 51´ (1.1 x 1.9 degrees) 1000 mm - 61´x 46´ (1.0 x 0.8 degrees) 1250 mm - 48´x 37´ (0.8 x 0.6 degrees) 1500 mm - 40´x 30´ (0.7 x 0.5 degrees) 1750 mm - 35´x 26´ (0.6 x 0.4 degrees) 2000 mm - 30´x 23´ (0.5 x 0.4 degrees) FEATUREScamera type: ASTRO Camera 16.0MP ATR3CMOS16000KPA data output: single pictures and video image Sensor: Panasonic NM34230PLI CMOS Color Sensor adjustable resolution: 4648x3506 / 2304x1750 / 1536x1168 adjustable binning: 1x1 / 2x2 / 3x3 frame rate per second (FBS): 22.5 / 43 / 48 physical sensor size in pixels: 4648 x 3506 megapixel: 16 MP sensor size: 17.6 x 13.3 mm (4/3 inch) pixel size: 3.8 µm x 3.8 µm bit depth: 12 Bit backfocus: 17,5 mm  shutter Type: rolling shutterinternal camera memory: DDR 3 RAMthermoelectric cooling with fan: yes, up to 40°C below ambient temperature adjustable exposure times: 150µs to 60min operating temperature: -10 to +50°C (30-80% RLH) cable length USB 3.0: 150cm DC cable length power supply: 200cm CNC machined aluminium housing camera diameter: 80mm; length: 102mm camera weight: 0,53 kg camera connection diameter: 2.0 inch ( 50.8mm) camera connection thread: T2 (M42x0,75mm) filter thread: Yes, 2.0 inch in receptacle camera connection to PC: USB 3.0 built-in USB hub with 2 x USB 2.0 ports power supply: Power supply 12 Volt 3,0 Ampere included software: EXPLORE Capture included camera driver and ASCOM driver includedoperating system: WINDOWS 10 + 11 PC requirements: CPU Intel Core2 2.8Ghz or higher / 2 GB Ram / USB 3.0 SCOPE OF DELIVERYDEEP SKY ASTRO Camera 16.0MP telescope adapter T2 thread to 2.0" (50,8mm) USB 3.0 connection cable 150cm power supply 230V/12V3,0A dust cap software CD hard case instruction manual

BRESSER Messier NT203s/800 Optical Tube
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.

EXPLORE SCIENTIFIC ED APO 102mm f/7 Alu FCD-100 Alu HEX
Highly corrected 102mm 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 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 by the focuser when the telescope is used for astrophotography with large sensors. These very popular EXPLORE SCIENTIFIC Triplet ED APO Refractors we do offer in 3 different product lines:Essential Line: HOYA FCD-1 Glass lens, AL-Tube, 2.0" Rack&Pinion Focusser with 1:10, 2.0" Star Diagonal 99% Reflectivity (see Part No. 0112084(AL), 0112106(AL), 0112132(AL)), 0112155(CF + 3"FT)) Professional Line: HOYA FCD-100 Glas lens, AL/CF-Tube, 2.5" HEXAFOC Focusser with 1:10, 2.0" Star Diagonal 99% Reflectivity (see Part No. 0112086(AL), 0112108(AL), 0112109(CF), 0112134(AL), 0112135(CF))High-End Line: OHARA FPL-53 Glass lens, Carbon(CF) Tube, 3.0" Feather-Touch Focusser with 1:10, 2.0" Star Diagonal 99% Reflectivity (see Part No. 0112165(CF))SPECIFICATIONSAperture: 102mmFocal Length: 714mmFocal ratio: f/7.0Weigth: 4,0kgBackfocus: 150mm above 2" adaptorDesign: Apochromat with three lenses, two air spaces and FCD-100 glassSCOPE OF DELIVERYOptical tube with retractable dew-shield2.5" HEX focuser with 1:10 gear reduction  2" Star Diagonal 99% reflectivityTube rings with dovetail plate and handleDust caps for front-lens and focuserUniversal finder slot

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 come together to deliver a telescope that offers observing and imaging at the highest level. The Carbon Fibre construction allows this telescope to be used on lower capacity mounts, increasing convenience and portability. Although there are smaller instruments available, the combination of aperture and optical excellence at such a low weight and compact tube makes this an excellent travel scope. The well-designed 2.5" HEXAFOC focuser with 10:1 reduction is perfect for both visual and astrophotographic use - the large inner diameter of 65mm prevents vignetting by the focuser when the telescope is used for astrophotography with large sensors (full frame and above).We offer the very popular EXPLORE SCIENTIFIC Triplet ED APO Refractors in 3 different product lines:Essential Line: HOYA FCD-1 Glass lens, AL-Tube, 2.0" Rack & Pinion Focuser with 1:10, 2.0" Star Diagonal 99% Reflectivity (see Part No. 0112084(AL), 0112106(AL), 0112132(AL)), 0112155(CF + 3"FT)). Professional Line: HOYA FCD-100 Glass lens, AL/CF-Tube, 2.5" HEXAFOC Focuser with 1:10, 2.0" Star Diagonal 99% Reflectivity (see Part No. 0112086(AL), 0112108(AL), 0112109(CF), 0112134(AL), 0112135(CF))High-End Line: OHARA FPL-53 Glass lens, Carbon(CF) Tube, 3.0" Feather-Touch Focuser with 1:10, 2.0" Star Diagonal 99% Reflectivity (see Part No. 0112165(CF))SPECIFICATIONSAperture: 127mmFocal Length: 952mmFocal ratio: f/7.5Design: Apochromat with three lenses, two air spaces and FCD-100 glassWeight: 5.2kg, lightweight due to carbon fibre tubeBackfocus: 150mm above 2" adaptorHybrid viewfinder shoe to accept different viewfinder holdersWHAT'S INCLUDED Optical tube with retractable dew-shield2.5" HEX focuser with 1:10 gear reduction  2" Star Diagonal 99% reflectivityTube rings with dovetail plate and handle Extension tubes for focuser (2pcs)Dust caps for front-lens and focuserHybrid viewfinder shoe

EXPLORE SCIENTIFIC 2" O-III 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 systems enormously. Depending on the type of the celestial object it is possible to increase the contrast dramatically by blocking the annoying artificial light. The EXPLORE SCIENTIFIC O-III filter uses a characteristic property of the so called emission nebulae. Those objects glow in special colours, the so called emission lines. Those emission lines are linked to chemical elements - in this case oxygen. The EXPLORE SCIENTIFIC O-III nebula filter blocks all other colours (and thereby nearly all of the artificial light) and only the two emission lines of the oxygen can pass the filter. The result is astonishing: suddenly nebulae are visible at locations that were completely empty without filters. In suburban skies for example the veil nebula NGC 6992 is almost not visible with a 200mm telescope. By using this filter you can see the nebula and its structures without problems. A must for every visual observer. The EXPLORE SCIENTIFIC nebula filters come with a individual test certificate - your guarantee to receive a premium filter.FEATURESenables the observation of so called emission nebulaeblocks almost the entire artificial lightonly the two emission lines of ionised oxygen passes the filterWHAT'S INCLUDED1x 2" O-III nebula filter

BRESSER Twilight I telescope mount with tripod
The Twilight I is a light-to-medium-duty alt-azimuth mount with tripod designed to quickly and easily accept small to medium sized refractors, such as the AR102 + AR127s or ED102mm + ED127, and of course, the ED80mm. Lightweight, fast Newtonians will also match up nicely with the BRESSER Twilight I mount. As long as your telescope does not exceed 18 pounds and has a Vixen-Style Universal Dovetail bar for mounting the telescope to the mount head, you are good to go. The Twilight I alt-azimuth mount head is made of powder-coated aluminum and there are worm gears on both axes. The adjustable angle head can be tilted forward or back at a 45° angle to allow more clearance for your telescope so you can point it straight up for viewing at the zenith. The Allen hex wrench for doing the mount head adjustment can be safely stored at the integrated magnetic holder.  Slow-motion control cables are attached on the vertical and horizontal axes, and are easy to turn during the night, even with gloves on, due to the over-sized knurled knobs that are attached to the end of each cable. They can be attached to either side of each axis to accommodate right or left-handed users, or different types of telescopes (e.g. refractors vs. Newtonian reflectors) for ease of adjustment. The stainless steel tripod that comes standard with the Twilight I mount has adjustable legs and a wide foot print of 42 inches, which makes the tripod more stable. A spreader bar locks against the inside of the legs to secure the tripod even further, and keep vibrations to a minimum. SCOPE OF DELIVERYTwilight I Telescope MountStainless Steel Field tripod
