How it works
Astronomers use a mono (black and white) camera with filters (eg Ha, Sii, Oiii or R, G, B) to capture high resolution images even in light polluted areas.
By combining these filtered images as R/G/B Channels, a coloured image is produced. This tool allows you to upload your black and white source images, then shows you every possible permutation for the various combinations. It is not intended as a replacement for colour combination in post processing programs such as Photoshop or PixInsight, but as a quick preview tool to see how the various combinations look.
