This flatfield Apochromat provides a color-pure and well-corrected image on the axis as well as in the field and thanks to the 2-element corrector in the OTA, it has a well-corrected image circle of 45 mm in diameter. This means you can also use cameras with full-frame sensors giving you a nice wider field of view of the target you are imaging.
Adaptation of Cameras:
The generous working distance is between 65mm and 155mm from the M68 thread and to connect a DSLR or an Astrocamera via the M48 thread, you will need the M68A-M48A-30 adapter. Cameras with a T2 (M42x0.75) connection will require a TSM48i-T2A reduction adapter. The adapter itself is only 6mm thick, so you still have enough space for a DSLR camera with T2 adapter or an Astrocamera.
