Downsizing Telescope and Mount

[tomdean]

I do not know where this belongs, but, it is sort of a beginners question.

I do Astronomy because I enjoy it. It is hobby. I have been at it for a dozen years, or so.

I had a Meade 8" SCT and iOptron CEM60EC plus associated lenses, etc.,  and a Cannon EOS 60Da.
I did a combination of visual observing and imaging with varying degrees of success. But, I had a lot of fun.
I used ST3/4 for planning, APT, skychart, BYEOS, PHD2, and platesolve3 for imaging.

Due to advancing age, I have to downsize. I have not kept up with advances in hardware.

I have ST4, both visual and imaging.

ST4 can control the telescope, slew and sync. How do I fold image and platesolve into this?

I have a AT65EDQ OTA and a iOptron CEM25EC and some Nagler lenses.

I want to add a camera for EAA with the provision to upgrade the AT654EDQ to a 102mm scope. For now, I want a cooled camera which includes a guide scope.

I am thinking of a ZWO ASI2600MM Duo camera. Will this work with the AT65EDQ, assuming I can find the adapters? I don't know about telescope output diameter.

If I buy the ZWO, what OTA should I look for, assuming I will upgrade?
