OGS 32" RC/SBIG STL-11000M CCD FITS files (Ready for Processing)
Listed below are links to FITS files for several of the data sets I have taken with the Optical Guidance Systems 32" Ritchey-Chretien Telescope and SBIG STL-11000m CCD camera.

These files will only be of interest to astronomical imagers who have the proper software to complete the processing of the images.

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.

Feel free to download these files and try your hand at processing images taken with a large scope under dark skies.

Should you decide to publish any resulting processed image (on a web site or in print), the only thing I ask is that the credit line include the phrase "Image Acquisition by Jim Misti".

You should be able to download each file by right-clicking on the file name and selecting the download activity in your browser, and then specifying a location on your computer to save the file. Each file is just over 20meg in size.
