Hi Alistair. taken from a rural township - sky about a mag brighter than dark (guess) along with with a neighbour's always-on outside light and a pesky streetlight that almost gets the solar panels working.
190xL 44xB 36xG 44xR all 5 minutes.
According to SIMBAD (if I read it right), the limit is around mag23 (V) - see attachment. Not real deep, but enough to show some detail.

yes I agree, some of the stuff out there can only bring a sense of wonder - what other hobby even comes close.

Thanks Rick - Hubble images quickly show just how limited our ground-based systems are - but it sure is fun to push things a bit.
