Description

This is a false color composite with the R channel being methane band (890nm, bp = 20nm), G channel being an Astronomik R filter and the B channel being an Astrodon UVenus. The saturation has been cranked and a high pass filter employed. It was a night with poor seeing and haze/high clouds, so the UV channel is very soft. Much/most of the "color" in the false color may be due to that alone.

This exercise also really illustrates how different the focus is at different colors with the short tube - almost a quarter turn of the focuser between the methane band and UV.
