NGC 2392 - now in color

hi guys,

o.k. here we are:
I have tried to kind of match the distorted and differently bended
rgb files with the luminance result I have posted recently.
I had to this in photoshop,...it was hard,...but it worked fairly
enough to present this l-rgb version here.

data:
luminance:
9"f/18 TMB Apo using televue big bralow
SXVF H36 - crop (as I told you less than 50% remained...it'S the
files issue that I will have to solve with a decent flattener...

l = 18x4 minutes
7 dark frames
r,g,b 9"f/9 5x4 minutes each.
maxim color calibration:
r=1.3
g=0.8
b=1.1

this was trial and error stuff, since I will have to do a G2V star
color balancing with the entire system...

thanks for taking a look.
