Thanks for the kind words everyone.
I do have one question that you guys might be able to answer for me.
I use an Orion 0.85x Flattener/ reducer. The star field is generally pretty sharp across the frame but the corners still suffer from coma.
I do notice that my subs tend to show coma/ focus issues in 2 corners while the other side is still pretty sharp. Example being in my lagoon image the left side (top and bottom corners) is pretty sharp but the right side starts to look a bit "out of focus".
Is this a spacing issue with the flattener/ reducer or is it a tilt problem??
I did also astromodify the camera myself so maybe its sensor tilt from that mod?? I know I didn't get the sensor spacing perfect for use with standard lenses, so thinking maybe it's slightly tilted also??
