Description

This 0.7x Reducer has been specifically designed for the ASKAR FRA600 f5.6 APO telescopes to achieve a very fast f/3.9 focal ratio and 420mm focal length for wide field full frame imaging.

It will connect to your telescope via a female M61 thread. (This seems to be very specific to this telescope, so we doubt that you will be able to use it with any other telescope...). The backfocus is 55 mm from the M48 thread and ther eis also a female M48x0.75 thread inside to be used with a standard 2" filter.

It offers a corrected and fully illuminated field for full frame cameras.
