The reflection Nebula looks nice, Scott!
Pity about the internal Star reflections!!!!!

What happened to get those reflections, Scott? It looks like the image has blue ring worms

The pleaides itself looks great! I imaged the HH until the moon came up.

Good image Scott. Obviously the blue spots are an issue. Any ideas on the fix?
Spent last night on Crab L's.
Cheers

Howdy
I believe they are reflections off the uncoated corrector plate. Its just ordinary plate glass .its even green when looked at edge on. A good AR coating on both sides may help but that would probably cost more then the total cost of the telescope.

Shame about the ghosting. If you've got a few good subs, you can always use pixel math to repair the other subs. This is simply a process of subtracting one image from another. Dithering between the subs would also assist.

Pity with those reflections, but if you ignore them, its a nice image!
