Since then I have not binned my RGB, haven't noticed a difference really. Have you looked at taking un-binned?
This is a good target for imaging from suburbia, as long as you have narrowband capabilities.

Hi Stuart,
I did some experimental sub frames & posted them on my thread here:
http://www.iceinspace.com.au/forum/s...d.php?t=115824
My post at 31-12-2013, 12:05 PM shows 3 mono pictures
comparing binning 1x1 & 2x2 with 10 minutes of exposure using Ha.
The results convinced me to go 2x2 on everything including Luminance
to increase the signal to noise ratio.

There is a graph & quite a read here:
