Description

Image Acquisition by Jim Misti. the data sets have been taken with the Optical Guidance Systems 32" Ritchey-Chretien Telescope and SBIG STL-11000m CCD camera. The files have been calibrated (dark subtracted, flat fielded, stacked, and aligned). They are ready for RGB combine and/or LRGB or HaLRGB combine in the program of your choice. The R/G/B filters used for all data were the SBIG set. I've experimented with various RGB color combine ratios, and my current starting ratios for the SBIG filters are R:G:B = 1.3 : 1.0 : 1.6. The H-Alpha images were taken with the Astrodon 6nm filter.
