Hi Gary, yes please, that will be fine re the charts 🙂 To be honest we’re getting so few clear skies now that I haven’t bothered uncovering my 24″ in 2 months. When there has been a few hours of ‘clear’ skies it’s either been with the moon up or high humidity – no use for low contrast, faint fuzzies. Had one decent 4 hour spell of mag 5.75 (SQM 21.35) skies in the last two months. Even doubles have been poor of late, milky skies and poor seeing so some VS observations might not be a bad idea.
Regards, Andrew
