Nice capture, you've got some good colour in the stars. I noticed that you're guiding now too, makes it harder when clouds are around but so much easier to get good subs consistently.

Thanks Rick. Guiding is essential at 2000mm. 1000mm I can get away without.

That's lovely, Kevin. Fine colours.

Thanks M&T. Only just got it in before the forever cloud rolled over.
