Here is a revised version of my original VELA supernova remnant 12 panel mosaic using some newer tools in Pixinsight and Photoshop.
Over 44 hours of acquisition over 2 seasons using the Askar 300 and the Optolong L-Ultimate.
Hopefully this version is a little better than the original greener version I had originally uploaded, the stars look better as does the background. The new gradient tools in pixinsight make a massive difference.
Enjoy
ASTROBIN version is Huge
