Orion Nebula, deeper
A couple days ago, I took some more shots to extend the total exposition time for this photo from 16 minutes to 38 minutes.
It certainly helped pull out more of the Running Man and the faint loop opposite M43 (better transparency the second time didn't hurt either). But I've had trouble processing it -- I don't know where those horizontal red lines are coming from. They're vertical with respect to the camera sensor, and I don't usually see pattern noise like that--it's not visible in the individual light frames (but to be fair, neither is a lot of the faint detail I managed to pull out of the stack).
