In more practical terms, things I am learning is how to take calibration frames, how many of them I need, how to frame targets when you don't have much of visual other than stars to give you that perspective of what you are able to capture, how to find your targets, why stars are tailing and how much you have to compensate for it. Not having access to Hubble telescope should not limit your ability to learn all the science behind it and gain that mastery with your equipment and have fun.
