TS-Optics 80mm F/7 ED APO Refractor for Astrophotography and Observation
Teleskop-Service's compact 80mm F/7 Extra-Low Dispersion ED Refractor is an easily transportable "complete telescope" for observing and astrophotography. Well-corrected optics offer a nearly colorless image thanks to the moderate aperture ratio and built-in ED glass. Use the APO refractor for astrophotography or impressive observations. The good optics, the "photo-friendly" 2.5" focuser and the good workmanship guarantee joy and success and wonderful experiences under the starry sky.
The advantages of the TS 80mm f7 ED refractor:
♦ very well corrected ED optics - adjustable
♦ Stable and precise 2.5" focuser - ball bearing drive tube - rack and pinion adjustment
♦ 2" bushing with reduction to 1.25" with compression ring and photo additional thread M54x0.75 for threaded connections
♦ Robust tube construction with fixed dew cap and CNC tube rings guaranteeing the best mechanical stability
The Duplex ED lens:
The handcrafted lens is in an adjustable, temperature compensated mount. It is a dual lens with an ED element for good chromatic aberration correction. We use the best possible manufacturer's multi-coating on every glass-to-air surface for optimal contrast.
The TS 80mm f/7 ED refractor is ideal for astrophotography:
The precise focuser and high-speed optics make the 80mm ED Refractor a good telescope for astrophotography. To correct the field of the image, we recommend the following correctors, which are also linked in the accessories area.
TSRED80 - Focal length reduction and field correction
This corrector is calculated for the 80mm f/7 ED and shortens the focal length to 448mm. Light intensity increases at f/5.6. With a 55mm working distance from the T2 threaded connection, you can easily connect all common DSLR cameras and also CCD cameras. We recommend the TSRED80 for DSLR cameras with APS-C sensors and for CCD cameras with sensors up to 30mm in diameter.
WiflatM48 - 2" field correction without changing the focal length... Excellent illumination - also suitable for larger sensors - a field of approx. 40 mm diameter is 100% illuminated. Working distance from the corrector's M48 thread it is 55mm.
