Here's a shot of the Keyhole Nebula. RCOS 12.5 inch (318mm) with AP .75 telecompressor for F6.75. Unguided on a Tak NJP mount that was really humming along beautifully.

Modified Nikon D70, Images Plus acquisition and stacking, Nikon Capture Editor for processing.

4 x 3 minutes unguided. I was getting up to 5 minutes unguided last night with a 2130 odd focal length - amazing. Shows the value of putting in the time on a good drift alignment.

The main yellow star there is Eta Carina, one of the most massive stars known to man. It blew a lot of its mass and that formed the nebula. It is an unstable star and could supernova.
