Product information

A fast focal ratio 70mm ED Quad APO Astrograph for wide field imaging with with full frame DLSR or CMOS cameras.

The quad design removes the requirement for a separate reducer or field flattener. While this fixes the focal length at 350mm making this a one focal length scope, it also allows for more compactness and portability.

The focal ratio is fast at F5 (350mm focal length), allowing for sharp star images and excellent performance and contrast with filters.
