    Glad I could help! Good luck. Just as a point of interest I did some Ha of the Butterfly Nebula last night and my flats were 14 seconds long each sub. Attached is one of my light subs (uncalibrated)

    That's a great image. I've yet to get into doing all this with the different filters. This whole thread was a good tutorial for me on how to calibrate my images.

    Ah, but the question for this Thread is "What does your Master Flat look like when Opened as an Image??"...

    What's funny is that I meant to post the flat but I posted the image by mistake. I tried to edit the image out and remove it, but for whatever reason it didn't let me. Here is a master Ha flat from a prior imaging run. I'll post an individual flat later..
