Hi Jase,
Yes there was a slight problem with green. I think it was either or both of 2 things:
I noticed at one point the lens had dew on it and I hadn't put my little insulation blanket around the scope as I rarely get dewing at my dark site.
At a guess I'd say dew is most likely to show up in the green image as I have noticed clouds/light pollution show up worst in the green channel.
There were also some clouds that moved in from time to time and these were fast moving. It is quite possible some moved in on one of the green subs. I have noticed before that clouds interfering with a sub often show excessive green in the colour image.
It was a difficult night and I have had a bad run of weather at my dark site. It used to be Sydney was cloudy and my dark site would invariably be completely clear.
Nowadays the weather pattern has shifted and Sydney has been very clear and my dark site overcast!
Greg.
