This was meant to be a long term project to go deep into this region, but it seems I have hit the wall with diminishing returns due to rising night time temps here in the tropics. Adding more data doesn't seem to do anything helpful at these temperatures. Might be my last nebula deep sky until next May!
I think the only thing that can help me now is a faster optical system.
About 6 hours of data for this one, mostly 5, 4 and 3 minute subs. Can't expose very long now due to thermal noise. Skywatcher ED100 at F7.2, Baader Semi-Apo filter, Pentax K-5.
