EXPLORE SCIENTIFIC TELRAD Projection Finder Scope with base
The TELRAD viewfinder is a projection finder that can be installed on any telescope and makes it child's play to align the telescope with the starry sky.The TELRAD viewfinder is a practical alternative to classic optical viewfinders and illuminated red dot viewfinders. You can see the complete starry sky without magnification, and not just a small section as with a normal optical viewfinder. Against this background of the starry sky, three red luminous concentric rings are projected, with apparent diameters of 4 degrees, 2° and 0.5° in the sky. Move the telescope so that the object you are looking for is in the inner ring, and the telescope points in the right direction. Because the object you are looking for is inside the ring, it will not be irradiated like a normal illuminated red dot finder.The base of the TELRAD viewfinder is self-adhesive and can be mounted on all telescopic tubes from about 10cm diameter. The length of the base is about 18cm. This base remains on the telescopic tube, the TELRAD viewfinder itself can be removed or attached at any time by means of the attached quick coupling. The TELRAD is powered by two normal AA batteries (not included).There are star atlases, like the "Deep Sky Travel Atlas" from Oculum-Verlag, and planetarium programs for the PC, like the program "Stellarium", where the three rings of the TELRAD are already drawn or can be displayed around the interesting celestial objects. This makes finding these celestial objects a real walk.FEATURESTELRAD projection finderIlluminated rings of 4 degrees, 2° and 0.5° in the skySee the complete starry sky without magnificationEasy installation and useCan be installed on nearly every telescopesBase with quick release coupling included Powered by two AA batteries (not included) Very long battery life because of LED technologySCOPE OF DELIVERYTELRAD viewfinder with projector and battery compartment TELRAD base with quick-release coupling for the viewfinder Adhesive tape for attachment to telescope

LUNT CAA-RF 0.8x reducer/field-flattener for nighttime photography with LS80MT, LS100MT & LS130MT telescopes
​Field-flattener and focal length reducer for deep-sky astrophotography. Designed for the multipurpose APO telescopes of the Lunt-Solar-Systems LS80MT, LS100MT and LS130MT series.At the telescopes of the MT series from Lunt Solar Systems, the H-Alpha filter unit for solar observation can be removed, then these telescopes can be used as high quality ED APO's for observing and photographing the night sky.This accessory for the LS80MT, LS100MT and LS130MT telescopes shortens the focal length by a factor of 0.8x, providing a larger field of view for deep-sky astrophotography. This also allows shorter exposure times. At the same time, the field of view is flattened for photography.On the camera side, the reducer/field-flattener has a T2 male thread (M42x0.75). DSLR cameras can be connected here directly with a normal T2 ring.For other cameras, an M48x0.75 male thread is available in addition to the T2 male thread. The distance between reducer/field-flattener and camera sensor should be around 50 to 55mm.An M64x1 thread is provided on the telescope side. This allows to connect the reducer/field flattener to the focusers of the conversion kits for the LS80MT, LS100MT and LS130MT telescopes. Please note that for using the reducer/field flattener at the LS80MT, LS100MT or LS130MT telescopes, the corresponding conversion kit for night-time use of the telescope is absolutely necessary..FEATURESShortens focal length of F/7 ED telescopes by a factor of 0.8xFlattened field of view for photographyT2 thread and M48x0.75 thread for camera connectionWorking distance 50 to 55mmSCOPE OF DELIVERY0.8x reducer/field-flattenerAdapter to T2 thread (M42x0.75) and to M48x0.75

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: https://www.touptek-astro.com/downloadsSample 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
