Hello,
 
    I'm not even sure this is the final version of this madness but I figured I better put something up... a few notes:
 
    Unlike many images from a CCD this is a pure RGB... it was shot 1X1 100 minutes on the red, 100 minutes on the green, and 160 minutes on the blue. Then it was done all over again for the OTHER half of the frame. The red and green exposures were done in 10 minute increments, the blue in 16 minute increments... all of these were reduced and then median combined. The final RGB's were combined in Registar as 16 bit RGB and the final image was extracted in PS.
 
    I tried to keep the greens from becoming too green... technically speaking they should have a bit more blue in them but it's easier to see the green contrasted against the red/magenta. 
 
    This was taken with the William Yang 4" f/8 flourite and the ST10E camera over quite a few nights... I learned a lot from this project... it's my first attempt with this set up...
doing a mosaic requires additional considerations.
 
    Anyway, if you have survived all this narration, here's the image:
 
 
     Have a good one,
