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

BRESSER Barlow Lens 2x 31.8mm/1.25"
With the usage of barlow lenses, you can extend the equivalent focal length of telescopes and hence increase the magnification of your observed targets. Subsequently, you can use lower power eyepieces in Barlows to act as much more powerful eyepieces, but retain the larger ocular size and more comfortable viewing that comes with lower power eyepiece designs.Due to their two lens design, these Barlow lenses provide a brilliant image quality for the whole visual field and are suitable for observations and photography.  The black coloured Barlow element cell in this BRESSER Barlow Lens 2x 31.8mm/1.25," can be unscrewed and has the same thread as 1.25" filters, allowing it to be mounted in 1.25" eyepieces, t-adapters and other accessories, giving you flexibility of use and the ability to vary magnification in different accessories.  For instance, the black Barlow cell screwed into the average length nosepiece of a standard push fit t-adapter will give around 1.6x magnification on an attached DSLR.  This can be very useful when trying to get to photographic focus with some Newtonians and Solar Telescopes, which lack the necessary amount of in focus travel to get a camera to a prime focus position.FEATURESsuitable for observations and photographydoubling of the focal lengthtwo lens designfully multi-coatedWHAT'S INCLUDEDBarlow lens (1pc)

EXPLORE SCIENTIFIC Teleextender 5x 31,7mm/1.25"
With teleextenders it is possible to extend the effective focal length of a telescope system, resulting in higher magnification for the observation of the moon, the planets or small Deep-Sky objects with the same eyepieces. So you can use the advantages of eyepieces with longer focal length - such as the bigger eye distance and the more relaxed observing comfort - at high magnifications also.These teleextenders incorporate a telecentric optical design that deliveres a excellent image sharpness over the whole field of view and are premium choices for visual observations and astrophotography. The combination of excellent fully multicoating with superior optical design makes the Focal Extenders superior to classic Barlow lenses.Features: Suitable for visual observations and astrophotographyExtending the effective total focal length of the telescope by a factor of 5xFour lens telecentric design Fully multicoatedFilter thread for color or nebula filters

EXPLORE SCIENTIFIC 1.25" 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 EXPLORE SCIENTIFIC 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 CLS filter

EXPLORE SCIENTIFIC Deep Sky Astro Camera 26MP
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

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
