I am currently trying to learn how to take projection shots but I must admit I am pretty much a beginner in all aspects of the task.
Camera settings, astrophotographic considerations, projection focusing - all these challenges are new to me.
Here's a link to the 4 best images I was able to obtain tonight -

My setup is as follows:
Skywatcher 6" dob
GSO 10:1 crayford focuser
2" 50 mm extension tube
2" to 1.25" adapter
Bintel superview 40mm 1.25" projection eyepiece
Canon EOS 400D with T-ring
hope I didn't forget anything
I will admit the images have some issues. What I would like to know is, based on what I have uploaded, what are the biggest limitations I have at this point* - and more importantly - can I expect much better without any major changes to my setup?
*what would you say are the largest issue(s) evident from my images?
focus?
other optical factors?
mount stability?
camera settings (ie. exposure time, iso setting, ?)
atmospheric conditions?
something else?
p.s. these images were taken with an ISO setting of 200 and exposure time 1/80
Thanks for any suggestions
