70 mm f/6.78 ED 4-Element Flatfield Refractor Telescope
TS-Optics 70 mm f/6.78 SD travel refractor for observation and astrophotography
The SD apo is an ideal travel telescope for all photographers. The telescope is very well corrected by the built-in corrector on the axis and in the field. In addition, the SD apo also offers a decent visual performance. Magnifications of up to approx. 150x are well handled by the lens, the chromatic error is significantly reduced. We recommend the telescope for all photographers who are looking for a portable, inexpensive and yet well corrected refractor for photography and observation. Since the corrector is built into the tube, the costly adapter battle is no longer necessary. Simply focus and you are automatically at the optimal distance.
The connection of accessories:
The TSED70Q has a very comfortable working distance of 135 mm from the 2" receptacle, so you can use 2" star diagonal mirrors and eyepieces and you can focus with ease.
To connect a camera, we recommend the adapter TSFA240, this adapter has 40 mm length and a T2 thread on the camera side. With this adapter you can connect all common DSLR, system or astro cameras. In addition, the focuser has an M54x0.75 female thread for screwed adapters.
