finding targets is the easy part, i have a heap of A star atlas's, B The sky6, Stellarium, and Asynx. I just picked the jewel box because i can point it out without even thinking. after the success i had with that i moved to something even duller. aka Triffid Nebular, on 18 second shots i could start seeing the nebulosity, though the stars where just white. when i bumped it down to 10 seconds the nebulosity dissapeared and the stars becaume a little bit duller as would expect but no colour.
As for the ADU theres a program in CDDops called Planet master which allows realtime view of what the ccd is picking up, i use it to focus in because of the peak value. is the peak value the ADU or is ADU the actual brightness of the star on the CCD chip?
I have also played with the Range and black screen in CCD ops that did little to help myproblem.
