For example with my AP RHA scope. I have a total of 165mm backfocus.
The Atlas focuser takes up 35mm, plus about 5mm for adapters, the filter wheel and camera take up 45mm and the adapter attaching all this to the scope is 39mm. Adapters between the MMOAG and the Atlas take up around 52mm and this allow enough room for the Atlas to achieve focus (it has 10mm of travel).

The ONAG takes up say 69mm + Adapters whereas I only have maybe 50mm spare.

Do you see any way around that?

Greg.
Hi Greg,

You are correct FL requires an ONAG.

Do you have a picture of your setup?
