Seeing as I am right on the starting line of the learning curve, I can't figure out how you folks can take images of several hours duration over several days
Do you have to have a fixed pier or something so that you can leave the telescope fixed up all the time? If you have to take all your gear inside every night, then drag it out again next day, how can you get spot-on alignment?? Then the stars will be in different places in the sky, so do you have to use special aligning software or something? If I tried to get my scope spot-on after a couuple of days, I can bet that the scope will be pointing in completely the other direction, clouds will be blocking the scene, the tripod legs will have sagged, the battery will be flat and the time will be all wrong
MUST be something I've missed!
