I have been imaging for over three years now, always with refractors and at the moment I have a roll off roof observatory, an EQ6-RPRO, a SW Esprit 100, an ASI294MC PRo and control it all with an ASI Air pro. I will move to NINA eventually but at the moment it just works! I would love a scope with a long focal length to go after some galaxies and the smaller deep sky objects but would appreciate some advice. I’ve looked at Newtonians, Cassegrain,s in all their formats but appreciate that collimation and other matters will come into play. If anyone has gone down this route I’d be pleased to hear from you.
Many thanks & clear skies
