EXPLORE SCIENTIFIC 1.25" H-Alpha Nebula Filter 12nm

The green filter is to increase the contrasts enormously between the red and the blue regions of the cloud structures on the gas planets Jupiter and Saturn. Seeing our Earth Moon through the green filter, the contrasts of each ray crater become clearly more visible.What ist a color Filter for and do we really need it ? Color Filters darken the light slightly, that reaches the eye or the sensor of the camera. This eliminates for instance stronger transitions. The result is that your picture turns out with more contrast which automatically shows more details.FEATURESMade from high-quality optical glassFilter glass is absolutely parallel All optical surfaces have anti reflex coatingsFilter housing from black anodized aluminumFilter threads on both ends (female/male)Multiple filters usage is possibleSCOPE OF DELIVERYColor filterProtection-case

High resolution deep sky camera with large SONY EXMOR IMX-571 APS-C CMOS sensor and active cooling. This camera's extreme sensitivity is achieved through SONYs backside illumination technology. This camera should appeal to both advanced users and those looking to move up from DSLRs for more serious deep sky imaging.Enter the world of astrophotography now. With the new EXPLORE SCIENTIFIC Deep Sky Astro camera you get a modern complete package for straightforward 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 for images are now history. Simply connect the camera to your telescope using the T2 female thread (M42, 0.75 mm) or the supplied 2" (50.8 mm) 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 this package 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 subtraction, stacking, timelapse recording and much more can be configured individually. This very sophisticated software makes your entry into astrophotography really easy. With the automatic settings you can produce absolutely presentable results without any previous knowledge. As soon as you feel confident, simply switch off the automatic settings and gradually explore the software's more individual professional settings. The new EXPLORE SCIENTIFIC Deep Sky camera has a highly sensitive and very low-noise SONY EXMOR IMX-571 APS-C CMOS Sensor, which can be 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 carefully automatically-controlled setting of the desired camera temperature, the it's easy to create of dark frames which can be re-used under similar shooting conditions - speeding up your processing considerably. The large-format CMOS sensor with 28.3 mm diagonal also allows large image fields and simplifies the adjustment and centering of objects considerably. The secret to the high light sensitivity of this camera is SONY's new back illuminated EXMOR CMOS sensor. It increases the quantum efficiency to up to 80 % at 533 nm, which leads to an extremely high sensitivity and subsequently particularly bright and high-contrast photos.The camera has a built-in USB hub with 2 x USB 2.0 ports at the rear. Connect your additional autoguider camera or motor focus etc. via a short USB cable and reduce the risk of cable tangles 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: https://www.touptek-astro.com/downloads Sample photos made by Lóránd Fényes in Hungary: https://fenyeslorand.hu/m31/https://fenyeslorand.hu/ic349_merope_nebula/https://fenyeslorand.hu/asztrofotok/Field of view for different focal lengths in arc minutes and degrees: 400 mm - 201´ x 135´  (3.4 x 2.3 degrees)500 mm - 161´ x 108´  (2.7 x 1.8 degrees)600 mm - 134´ x 90´  (2.2 x 1.5 degrees)700 mm - 115´ x 77´  (1.9 x 1.3 degrees)800 mm - 100´ x 67´  (1.7 x 1.1 degrees)900 mm -  89´ x 60´  (1.5 x 1.0 degrees)1000 mm - 80´ x 54´  (1.3 x 0.9 degrees)1250 mm - 64´ x 43´  (1.1 x 0.7 degrees)1500 mm - 53´ x 36´  (0.9 x 0.6 degrees)1750 mm - 46´ x 31´  (0.8 x 0.5 degrees)2000 mm - 40´ x 27´  (0.7 x 0.45 degrees)FEATURESCamera type: ASTRO Colour Camera 26.0MP ATR3CMOS16000KPA Data output: single pictures and video Image Sensor: SONY EXMOR IMX-571 CMOS Colour Sensor Adjustable resolution: 6224x4168 / 3104x2084 / 2064x1386 Adjustable binning: 1x1 / 2x2 / 3x3 Frame rate per second (FBS): 6.8 / 28 / 63 Physical sensor size in pixels: 6224 x 4168diaginal: 28.3 mmMegapixel: 26 MP Sensor size: 23.48 x 15.67 mm (APS-C format)Pixel size: 3.76 µm x 3.76 µm Bit depth: 8 Bit / 16 BitBackfocus: 17.5 mm  Shutter Type: rolling shutterInternal camera memory: 512MB 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 WHAT'S INCLUDEDDeep Sky Astro Camera 26.0MP Telescope adapter T2 thread to 2.0" (50,8mm) USB 3.0 connection cable 150cm Power supply 230V/12V 3.0A Dust cap Software CD Hard case Instruction manual

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: 2.0 inches / 50.8 mmConnecting thread: M48x0.75mmSelected 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)

​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
