I must warn you I'm totally new to astrophoto. I'm able to operate my 6inch Newtonian on a German Equatorial Mount (celestronAVX) as well as my DSL via BYE. I live in a very light polluted sky so the live view of my camera does not show any star on which I can focus. So I have to go by try and error (roughly 15 images until I'm satisfied). My DSLR has a SkyTech CLS Canon EOS Clip Filter which it's giving good results. My question is: Is there a technique on how to achieve focus if no star shows on the camera's live view? Can I try to point the telescope/camera to a brighter star, visible in the camera's live view and then move to the target that I want to shoot?
My equipment :
Canon 450D EOS
SkyTech CLS Canon EOS Clip Filter
Deep Sky Stacker
Attached is my first image of M31 Total exposure time 22 min (lights, not enough darks, and flats) BTW this is a post-prod image in PSD in order to get more detail only
