SV209 1.0x Flattener Corrects the Field for SV550 80F6 Astrophotography

The Calculation Method of 55mm Back Intercept

First unscrew the 2-inch adapter ring of the SV550 80mm APO, and then connect the three parts of the field flattener. The installation sequence of the three parts is shown in the figure above(don't confuse the order) . Then connect the mount (not included) and camera compatible with Canon to shoot.

SV550 80 OTA Field Flattener

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.

M63 Extension Tube

Equipped with M63 extension tube and M48 adapter ring to ensure that the back focal length of the field flattener is 55mm in astronomical tradition.

Thread size: M63x1 male thread


M48 Adapter Ring

Built-in 2-inch filter mounting threads support 2-inch filter mounting.

By connecting the adapter ring, you can match any 2-inch filter you need to meet your different shooting needs.

Connectable CAA Field Conditioner

SV209 can be installed to create flat images. At the same time, it can be installed in combination with the SV210 (sold separately) to adjust the field of view of the image.
