Have a read through this , it might help you

I was in your situation  however we all have different requirements.
I considered the 6D but it had just been released and was a further $600 dollars on top of the 60Da price. Plus the full frame wasn't suitable with the hyperstar lens with the largest usable sensor diagonal dimension being 27mm.
The 6D is a way better camera and if you want to do mainly nightscapes then It would be the way to go. But if you just purely want it for asrtophography and no daytime shots, @ 2K plus, I'd start looking at CCD camera's |
Thanks for this advice Rod, I much appreciate it
But isn't a full frame sensor a better light bucket and wouldnt make a difference if you attached it to the hyperstar? What would then happen if you attached the 6D to the hyperstar?
Sorry, I just want to get my head around this
