Hi guys, finally got some first light with my new homebuilt DOB, 16-inch f/4 mirror. The views were outstanding, by far the best I've had without question...but I noticed something I had not noticed with my other smaller scopes I've used, when moving around the surface of the moon to view across the moon surface the curvature of the moon required me to refocus. I could refocus without issue but is this normal, is this a good sign showing the optics are good or does it show an issue? I was not using a paracor corrector and was using a 2-inch FMC 30mm, I did Laser Collimation.

Thanks
Paul

Looking for some opinions guys...Looking for which of these would be best all around scope for visual deep sky and planets mounted on something like the SV MG2 mount with encoders. I like really sharp images and high contrast...Any help is appreciated. Price range no more then 3-4,000.
