Horsehead and Flame - Ha

About this image

Captured over several moonlit nights from November to 7 January. Also captured RGB when the moon was absent but very disappointed with the results due to the halo of Alnitak, hence, only Ha here. Processing in Pixinsight.

I have noticed that the jpeg version looks rather over-processed. The flame looked unnatural and background too dark. I have now replaced with a version that has not lost so much data.
