The Trifid nebula in SHO (Hubble Palette) 5-9Aug2021

M20 or NGC 6514 is a popular and bright nebula about 4300 light years away in the constellation Sagittarius.

This image was taken during the same nights as during the "experiment image" posted a few days ago. The difference here is that this image is not intended to be presented in natural color and instead of using the H-Beta channel, I used the Sulfur II data, SII as Red, H-Alpha as Green and OIII as Blue.

Imaged through a 8" SCT at f6.3 using a QHY268M camera, for a total exposure time of 11 hours and 20 minutes.
