This image is another test image using my new 250mm f/4 Mak Newt astrograph. The camera was an STL11k. The H-alpha filter was 6nm. Eight frames of 900 seconds each were stacked to give this 2 hour test exposure. I'm pleased with the depth and detail. New to get some RGB.....

Any thoughts?

Best,
Tom

Looks like your setup is passing the test with flying colors (okay, the color is yet to come). And surely a great example of your earlier comment on post to go long with Ha. Now that I seem to have guiding that can handle it, I will certainly follow the advice and example.
Thanks,
Larry

You're getting very refractor-like stars for a 10 inch compound scope.
