This 0.76x Reducer has been specifically designed for the ASKAR 80PHQ f7.5 APO telescopes to achieve a faster f/5.7 focal ratio and 456mm focal length for wide field full frame imaging.
By using this reducer you will effectively shorten the exposure time and dramatically widen the field of view.
It will connect to your telescope via a M68 thread. As shown on the below images, you will reuse the multi-thread adapter that came with the 80PHQ and place the reducer between the telescope and the unscrewed adapter. The backfocus is 55 mm from the M48 thread and there is 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.
