Hi. I processed M104 tonight. This stack of 29 x 4min images, from 8th May, contains a bright object in the lower right corner which is slowly moving over the 3.5 hours that the shots were taken. I continued imaging M104 the following night but the object is not there.
I hope someone on iceinspace might know what it is?
My scope is a 16" f5 newt. Camera used was a QHY8.
Clear skies
