Managed to collect some data after dodging cloud.
Exposures 16x4 minutes for each RGB.

It was quite cold and clear. The data was collected around the zenith which minimises the effects of light pollution. I think the new hood extension was worth the effort.
It is a result like this that makes a sleepless night worthwhile.
