New BORG Flattener

Prototype of BORG new field flattener is coming to me soon. It is 1.08x ratio covering full frame sensors and works with 300mm to 800mm focal length. Here is tables for current and future BORG astrograph configurations. If there are someone who are looking for longer focal length but not too slow, this should be the one.

1.08x flattener is expected to be released in March.   Another 0.65x for shorter focal lengths is scheduled before the summer.
