One of the gems of the southern sky, the Carina Nebula spans over 300 light years and is located around 7000 light years away.
Taken with a 80mm refractor and QSI583wsg camera
1 set LRGB images, 180s each
Calibrated, aligned and RGB combined in MaximDl
Luminance and RGB images stretched in Photoshop.
I did things a bit differently after that. Using Annies actions in Photoshop, I removed the stars from the luminance image and stretched it a bit more to bring out the nebulosity.
I then combined it as a luminance channel with the RGB at 50%. That made the stars look funny, so I added a normal luminance channel in as well at 25%.
Some noise reduction and colour balance.
