Description

This is a pretty difficult target. It is very faint and requires dark skies, excellent seeing and serious integration time. The image was shot with a dual narrow band filter because it is an emission nebula. This stack was processed via the standard Siril OSC script. I will post another image processed with the Siril OSC Ha/OIII extraction script for comparison. This image is made up of 96 300 second exposures. Hopefully I can at least double the amount of data in the coming nights.

The Lion Nebula ( Sh 2-132) is thought to be between 10,000 and 12,000 light years away.
