Spot on SAB, it's not the scope or my modest skills, it's the skies. Last night was exceptional. I've never really tested what mag skies we have - from home it's pretty good, but Porepunkah is always better.
When the transparency is that good, a million viable targets open up for you even with a 4.5". For instance, there was a mag 12.1 galaxy in the list above that even though faint was quite easy to pick up scanning through the field. However it was positively 'bright' compared to other tiny, very dim ones I saw while scanning around Dorado. Now I only identified the ones that were on the chart, and these were the brightest. What mag were some of these others?
But if I lived in Melbourne I'd probably battle to see OC, and have to go out and get me one of them there cannons, LOL!
Cheers -
