That makes sense then.
Glad you took the minor but constructive critisism in the right spirit! It is always hard to make public comment on an image other than just saying "great work" or "incredible" etc.. without sounding like a nit picker or stick in the mud.
One day I'll have a go at planetary imaging myself with the Starfire and then you can have a constructive critisism field day!

ps. Great work and incredible image by the way!
