Thanks Mike.

The lack of total exposure time limits the amount of sharpening I can do to it. I will add more exposure time to it like I have for some other images.
Clear weather has been so rare lately and it is still quite low in the sky.

I like the image scale but I am having trouble with bright star flares
just out of the image. I have to track down where they are coming from over the next week or so. But overall I like the CDK17. I think I'll be able to handle these flares and they are only a problem occassionally.

I need to make sure I turn the fans on early to let it equalise as you can't get a sharp focus with more than about .5C difference between the primary and ambient temperature. It takes maybe 2 hours to get there. Perhaps a little AC unit may help.

Greg.
