Strange M42 artifacts.
HI All,
I was wondering if somebody has come across this strange artifact in an image I took last night of M42.
It is a stack of 5x 10 minutes, 20x 30 seconds and 20x 15 seconds. I am using the QHY8L, the gain and offset are 5 for gain and 30 for offset.
The camera was sitting on -15deg the whole night.
As you can see from the image there are a couple of strange lines running across the image toward the bottom.
Any ideas what may have caused them??
Paul
