1. Yes pretty much. 2. Yes the artifact shape is related to the mirror shape, and the support arms which block some light. this is called a Diffraction spike. There are a bunch of fake web telescope image videos on YouTube with 4pointed diffraction spikes so you can tell they are taken from a different telescope. https://en.wikipedia.org/wiki/Diffraction_spike |
