SH2-91 - The "Other" Veil Super Nova Remnant

About this image

This image is a 20 hour integration.

The density of stars in this region is immense, and threatens to overwhelm the detail of the Remnant and had to be reduced extensively with regards to their intensity during processing, though some still remain oversaturated in the final image.

I didn't have time to do the whole region so focused on the main target of SH2-91

Pleased with the level of Oiii and Ha data captured - this was a difficult one to process - trying to see if I captured Minkowski's footprint but not sure if it's there or not.
