Sharpstar-Askar
Sharpstar Optics, founded in 2000, is specialized in research, development and production in the field of astronomy. Sharpstar and Askar are the two of the company' s brands dedicated to providing customers with high-quality products and services. In addition to a series of high-quality astronomical telescopes widely praised by the market, it also has a strong OEM background for more than 10 years.
The Askar 80ED with 80 mm aperture and 560 mm focal length offers good color correction and is ideal for mobile use.Aperture 80 mm / focal length 560 mm / focal ratio f/7
- Improved color correction due to the use of ED glass
- High-quality dual-speed R&P 2" focuser - optimized for astrophotography
- Motorized focus systems, like ZWO-EAF can be adapted directly
- M58x1 external thread on the focuser for screw adaptations
- Correctors for astrophotography calculated for the ED available (0.7x, 0.85x and 1.0x)
- With a weight of only 2 kg and a transport length of 40 cm, ideal for traveling
- 2 finder shoes, CNC rings, dovetail bar, carrying handle included in the scope of delivery
The corrector allows astrophotography up to full-frame with the Askar 80ED while increasing the speed to f/4.9.
- The corrector is designed for the Askar 80 mm f/7 ED and provides an optimal correction of the field
- The focal length is reduced to 392 mm and the focal ratio is improved to f/4.9.
- screwed connection to the focuser via the M58x1 thread
- thread on the camera side - M48x0.75
- Working distance 55 mm from the M48 thread
- Internal thread for 2" mounted filters (M48x0.75) is present
- 360° rotation for optimum orientation of the camera in relation to the object
The corrector allows astrophotography up to full-frame with the Askar 80ED while increasing the speed to f/5.95.
- The corrector is designed for the Askar 80 mm f/7 ED and provides optimal correction of the field
