If for some reason, (and in astronomy lots of bad things can happen using complex telescopes and CCD's) you're not happy with with one or more of your data/images your welcome to use the "Self Service" points return system or contact Support if it looks serious.
Please use the link found on your telescope Usage Receipt as shown below.
Try to be fair, if only ONE of your 10 images is bad, then divide your total charge by 10 and make a refund request for that amount. We do keep track of requests and there are limits.
As Always in Astronomy - Be aware of WIND, LIGHT CLOUD and the MOON before you start a long imaging session.
