Tecnosky 0.8x focal reducer for 70/72ED APO

New 0.8x focal reducer for Tecnosky 70ED and 72 ED Apo refractor. Screws directly onto the focuser drawtube to avoid annoying push-ups, camera side has an M48 thread with a required back focus of 55mm. Thanks to the large M48 thread the leveled and illuminated field will be superior to the classic APS-C. 

Towards the telescope, there is a thread M63x1 and an M54x0,75.
