Questions for the 🔭#astrophotography gurus. Having only used a camera on my Lunt which was noddy, I am unfamiliar with the tech. I just got my new Orion Optics MKC-140 and mounted on a ZWO AM3 mount with an ASIAIR+ & guide scope. But need guidance for suitable camera kit (a thread):

Can I attach the camera to my Televue Powermates? Should I invest in a focuser? Filter wheel? When money permits (or someone nice donates) I would like in future to get a WO Refractor (like a Flourostar) will that require anything different? And finally, current best stacking/processing software?

Advice on a suitable camera- not too expensive as I spent all my money on scopes! What else is needed? I want to do planetary and Deepsky to compliment the Origin. Colour or monochrome (stacking filtered images to do "colour" I guess, or is that not good)?
