Dennis.. I think due to the edge on rings this time around capturing a great image of saturn is going to be difficult.. I find with my DBK frame rates and exposure times need to be fairly long in order to properly expose the histogram making it difficult in all but the very best seeing to capture a great image.. None the less you've done very well indeed...
Very clever of you to blend colour and mono data to reveal things that the colour camera couldn't reveal on its own..
Nice image of Saturn Dennis.. Hopefully a sign of things to come this apparition....
Cheers.
