This is 10 minutes each of RGB. No L. Done with the same setup where I figured out afterwards that the collimation was a bit off. (^$%#@ - does that have an emoticon?) I should probably go back, collimate, and get some L on this one and see how sharp I can get the stars. Still don't know if that had much more effect than the wind and/or tracking, but something that should be fixed. If I use an electronic focuser, can someone explain why I don't at least look at an out of focus star every night anyway?

As always, processing suggestions are most welcome. Thanks for looking.

Charlie

Looks good Charles.

I'm not sure if luminance would help on this or not?

If you check collimation every time before using the scope,you might end up playing with adjustment more than imaging!
