M42 and the Running Man nebula with Takahashi 150mm

  1. Dec 12, 2013 #1
    First post on PF, thought I'd share my first serious attempt at astrophotography. I used itelescope since it's perpetual cloud cover where I'm at sadly, and all of my processing was done in Astroart. I learned a lot with this, but it's definitely an uphill struggle!

    Total exposure time was 40 minutes (10 in R,G,B and Ha each) and the equipment was a Takahashi 150mm refractor with an SBIG STL-11000M CCD.

    Nice. Did you use HA as a luminance frame?

    Sort of. I tried to use just the H-alpha image as luminance with the RGB but it made the stars look really weird, especially with large halos around the brighter ones. I looked around and found Rob Gendler's website that discusses ways around this, and it helped a lot. One of his solutions was to lower the opacity of the Ha image relative to the others, then integrate it, and that did the trick for me.
