Hey! I think I kinda went the other way around unlike many others, I've been imaging for a pretty long time now with a cooled ZWO camera and few different telescopes.
But I also wanted to do milky way/wide DSO imaging, which is why I bought a Canon 6D astro modified and AZ-GTi mount + wedge to use it in EQ mode as a portable/secondary rig.
For the time being I only have an extremely low quality lenses, 15-55mm lens, and a 70-300mm lens, both of them are pretty bad for astrophotography, but I guess that's what I can do for the time being, I also own a SharpStar 61 EDPH II which is 275mm with a reducer, I think that's close to the AZ-GTi's limit, but maybe still usable.
I think I plan on using a raspberry pi along with astroberry or just an ASIAIR along with it, not really sure yet, I'm wondering what other accessories would I need or would be a good purchase in terms of battery life(multiple batteries? Powered battery?), convenience(shutter release? Even though I shouldn't need that with ASIAIR/astroberry, but for milky way imaging possibly?), basically, just whatever comes to your mind that an average user might need.
Thanks for the help
