Lighthouse: thanks for the heads-up on the night sky.

I had the same problem years ago with a 2000mm telescope and a Olympus OM1. Found out I needed a different focusing screen. The OM1 had replaceable screens. This resulted in a few prize winning shots with amazing detail. I also have a 5200 and ask my buddy at Sunny Schick just yesterday if it was possible to connect my equipment. I need to find an adapter before this question can be answered. Would love to hear of ANY success you have because I also enjoy "shooting the moon".
