M51 with G2V Calibration
I was able to catch 80 min. of one my favorites (M51) on the night of 4/22.
Location = Portland Downtown
Temperature = 46-48F
80subs x 1 min. = 92min.
80L x 40 Darks x 40 Bias x 40 Flats
Main Telescope = Orion Mak 150 FL=1800mm + Canon 40Dh
Guiding Scope = ST-80 + SSAG
Mount = HEQ5 Pro
Processing: The usual suspects for processing = DSS with Mediam Sigma-Kappa Clipping, Photoshop, Carboni and GradientXTerminator and Ninja Noise.
Regarding, the G2V calilbration, still learning, but given that this image is still lacking 100 min. of data, I think it is pretty good in terms of color balance.
