Is the 2600MC Duo an appropriate camera for the RASA8 or does it have a wider camera body than the 2600 Pro and block too much aperture? I have a ASI2600 MC Pro that I use with a RASA8 connecting with at Artesky filter adapter. I note the MC Pro uses an M42 adapter and the Duo an M54 -- do I need a new filter adapter, does ZWO make one or where else can I obtain one? I do not necessarily want a filter adapter just want to be sure I can connect the camera to the telescope.
