Funnily enough i took the images right next to a damn street light, but i tried to block it with a screen! I managed to get the setup to track with good exposures without trails up to four or five minutes (EQ6 Pro). That was achieved by attaining polar alignment using drift alignment with an illuminated reticle eyepiece. What i don't get is why was the camera still on the target five hours later? Surely it would have drifted out of view by then...or does the mechanical error in the drive even out over time to just an average variation? (rendering an unsteady cycle useless for long exposures). Also i have a 12" dob and even in dark skies i can instantly see the green nebula in Orion, so if not light pollution what would cause this? Perhaps I need to get a guide scope and autoguider, and even a main scope of higher quality to answer these questions (but I wanted to do it the hard way first!). So many questions????????
