Description

The final of a trio of images in my Rosette Nebula project...

Since the autumn of 2021 I've been gathering data on NGC 2244 with each of my 3 OTAs... the Redcat 51, Esprit 100ed and the EDGE HD 8"

I have processed this particular data before but never published it on Astrobin as I’ve never been happy with the result…

This image is with my favourite rig, the Skywatcher Esprit 100ed coupled with a ZWO ASI 2600mm Pro and using Optolong 3nm Narrowband filters
The Esprit 100ed is so reliable, it has great pixel scale with this mono camera and produces superb sub-frames

The image was processed in Pixinsight, combining Sii, Ha and Oiii stacks after star removal and in the 'Hubble' SHO format using this Pixelmath expression:

R/K   0.6*Sii + 0.4*Ha
G       0.7*Ha + 0.3*Oiii
B       Oiii

I decided to leave quite a bit of green in this image, somewhat different to my other 2 edits as I wanted a wider colour palette.
So this would work I had to keep the colours muted and carefully accentuate the dark structures using layers in Photoshop.
There are so many veil like structures in the core of this nebula that I found care had to be taken not to 'blow' these out with over-processing...

I hope you like the result, I've enjoyed my time with NGC 2244... it's a wonderful, awe-inspiring and tiny part (!) of what is out there to be imaged...
