STACI

STAr Color extInction

STAr Color extInction (Staci) is a Windows application for calculating RGB color adjustments for atmospheric extinction.

The program extracts the acquisition altitude for each red, green and blue FITS sub exposure. After determining the average altitude, for each color, the color corrections are determined. Additionally, the program applies these corrections to the image-train's standard color calibration.

If you normalize your color sub exposures:

Only use one image for each color channel. Use the image that is the base for the normalization.

To install, just download and unzip Staci.zip into your desired folder.
