    I finally had a clear night last night, though seeing wasn't the greatest.

    I decided to image the Triangulum Galaxy. I had only imaged this once before when I was first starting out. It turned out MUCH better than my last attempt.

    This is an LRGB +Ha image

    Lum= 80, 60 second images at Bin 1x1
    Red= 80, 60 second images at Bin 2x2
    Green= 80, 60 second images at Bin 2x2
    Blue= 80, 60 second images at Bin 2x2
    H-Alpha= 20, 180 second images at Bin 2x2

    M33 is roughly 3,000,000 light years from Earth. It has huge regions of Ionized Hydrogen clouds that are star factories. They show up as the red area on this image. The Hydrogen regions are so large, some of the largest known, that they are easily visible from earth, which is very rare.

    Hard to not be amazed at the sight of this scene. Even more so knowing a little about what I am looking at here.
