And I thought I was big. Actually that's what I do as another hobby, imaging far away space "stuff" like nebulae, galaxies (some colliding), star clusters, exoplanets, a few planets, and other space stuff. I have a home observatory with roll off roof we built when we built the house and run a remote system in California at a place called SRO Observatories. I've also help setup numerous telescopes (24-32") at various universities and worked on setting up and getting operational their CCD imaging systems. This like woodworking is a hobby........I'm retired.
