Feature
- 1.Most astronomical telescopes have a certain field curvature problem, which can be improved with SV209. The SV209 is a special field flattener for SV550 80F6 OTA, which can effectively improve the field curvature of fringe field images. Great for astrophotography.
- 2.The SV209 is equipped with an M63 extension tube and an M48 adapter ring to ensure that the back focal length of the flat-field lens conforms to the traditional astronomical 55mm.
