I want to put a camera on my SW ED80 and dip my toe into the world of astrophotography. My intent is to buy a DSLR (up to $1k). The DSLR would be used for general photography as well (justification to better half

).
The Sony a6000 ticks a lot of my boxes for non-astro work. Has anyone here got an a6000 on their ED80, or am I barking up the wrong tree and should be looking at a Canon/Nikon something???
