EXPLORE SCIENTIFIC 2" S-II Nebula Filter 12nm
​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

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 Ritchey–Chrétien 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

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

BRESSER Spica-II 130/1000 EQ3 Reflector Telescope with Smartphone Adapter & Solar Filter
Embark on a voyage of discovery through our solar system and beyond using the BRESSER Spica-II reflector telescope. You can start straight away with your new hobby, because this complete astronomy set already comes with everything you need for exciting observations: an astronomical reflector telescope with 130 mm aperture and 1000 mm focal length, an equatorial mount, a tripod and extensive accessories. Perfect for the astro-novice: the system is very easy to use. So look forward to fascinating sights especially of the Moon, the planets and the Sun. Perfect combination of mirror and lens – the telescope Using the Spica-II you’ll start your celestial exploration tour with a classic reflecting telescope of the "Newton" type with an additional lens inside the focuser. This combination of mirror and lens is called "catadioptric". It’s immediately noticeable with this type of telescope that you do not look in at the back, but at the front and laterally. What is the advantage? Even if the telescope is pointed vertically into the sky, you can observe the beauties of the night sky in a comfortable posture. In addition, catadioptric telescopes impress with their transportability, because despite the long focal length, the tube is comparatively short. With its 130 mm aperture, the Spica-II already collects a lot of light from celestial objects. In addition, 130 mm aperture and 1000 mm focal length result in a focal ratio (ratio of aperture to focal length) of 1 to 7.7 (F/7.7). This means you can enjoy an image with good contrast even at high magnifications. Thus, the telescope is well suited for observing the planets and details on the Moon. Even some deep sky objects are worth looking at through this entry-level telescope: admire open star clusters and globular clusters as well as bright so-called planetary nebulae such as the Ring Nebula M57 in the constellation Lyra. And how big will the nocturnal highlights appear? The 130 mm aperture achieves a resolution that allows magnifications of up to about 260x with sharp images. Technically, even more is possible – theoretically up to 750x with the included accessories. However, as the magnification increases, the sharpness of the image may slowly decrease. In addition, as is so often the case in astronomy, you are also dependent on the prevailing conditions. For example, the air turbulence in the atmosphere (seeing conditions) always plays a role in your magnification possibilities. Note for nature lovers: If you choose a Newtonian telescope like the Spica-II reflector telescope, you can look forward to a specialist in astronomical observation. However, the image is always displayed laterally reversed as well as upside down, which makes no difference when observing the sky. However, this type of telescope is less suitable for nature and landscape observation during the day. Would you like to use your new telescope for exciting nature discoveries as well? Then we recommend that you choose one of the BRESSER refractor telescopes. A good foundation for your astro-start – mount and tripod If you want to look up at the sky, you need a solid base on the ground. That's why you will find a robust height-adjustable aluminium tripod and an equatorial mount in your telescope set. The special advantage of this type of mount: unlike an azimuthal model, the movement of the celestial bodies is compensated for only on one axis instead of two. For this purpose, one axis of the equatorial mount is aligned parallel to the Earth's axis in the course of the so-called "alignment". This is easily done by pointing it approximately at Polaris. Perfect for convenient adjustment and tracking of the entry-level telescope: the axes can be moved precisely via the two flexible shafts with fine adjustment. And if you simply place smartphone adapter, eyepieces etc. on the convenient storage plate between the tripod legs, you will have the equipment you need quickly at hand.Keep track of things automatically: For this telescope’s equatorial EQ-3 mount, the tracking motor with item number 4951400 is available as an optional accessory. This eliminates the need to manually track a celestial object set in the telescope. When this motor is installed at the mount, it automatically tracks the celestial object, keeping it in the field of view of the eyepiece. This makes observing the night sky even more comfortable! Everything for the astro-beginner – the accessoriesFor your start into the wonderful world of astronomy, the Spica-II beginner's telescope comes with lots of accessories. The LED viewfinder, for example, is great for orientation in the night sky. You simply install the direction finder parallel to the actual telescope. It projects a red dot onto a small ground-glass screen that appears to float in front of the sky when you look through it. In this way, it shows you where the telescope is pointing. A great help for the exact alignment of the telescope and the easy location of celestial objects before you gaze at them with higher magnifications. You determine how detailed you observe your discoveries by using one of the two eyepieces, each of which provides a different magnification. They are fitted with standard 1.25-inch (31.7 mm) diameter sockets which allow them to be easily inserted into the eyepiece focuser of the entry-level telescope. Would you like to look even closer? Then grab the 3x barlow lens, which triples the magnification of the eyepieces in no time. Explore the astronomical highlight of the daytime sky: With the safe solar filter you can examine sunspots as well as granulation on the Sun. CAUTION: Never point the telescope at the Sun without the solar filter! There is also a suitable accessory for your first steps in astrophotography: with the smartphone adapter, you can use your mobile phone as a camera on the telescope. First snapshots of the Moon or Sun made easy! FEATURES Reflector telescope with 130 mm aperture and 1000 mm focal length Reflector type catadioptric Well suited for observing the Sun, Moon and planets Height-adjustable tripod with equatorial EQ3 mount Precise adjustment through flexible shafts and fine adjustment in both axes Easy to use, very good for beginners Focal ratio F/7.7, therefore good for observing the planets and details on the Moon 1.25-inch focuser (31.7 mm) Two eyepieces and one barlow lens with 1.25-inch (31.7 mm) sockets for different magnifications Safe solar observation with the included solar filter First steps in astrophotography with smartphone camera adapter SCOPE OF DELIVERY Telescope Aluminium tripod Equatorial EQ3 mount Eyepieces: 4 mm and 20 mm (1.25-inch sockets) Barlow lens 3x (1.25-inch socket) LED illuminated viewfinder Solar filter Smartphone camera adapter Accessory tray Astronomy software as download Instruction manual
