What a difference a very bright object can make to imaging times. This image of the great Carina nebula is composed of 13.6 hours of data.
It is composed of :
SII 150 minutes
Ha 270 minutes
OIII 120 minutes
R 100 minutes
G 80 minutes
B 100 minutes
This image is essentially a narrow band image with an overlay of RGB colour to enhance the detail of the narrow band data.
