So I was getting some data on M51 for Goofi's monthly challenge and noticed an odd artifact on one of the stars. It is on the top of the image, it appears that there is a blue material being ejected from the star. I checked some other images people have taken, and it does not show up there at all. I thought it might be something to do with the micro lenses on the camera, but it is not symmetric. Is this an optical aberration, or something real?
Camera is a QHY294C, scope is a Meade 130mm APO.
Forgive the brevity of the message its 3am and I'm tired.
