Great to see your obs reports here! Ever since Melbourne became cloud yet again, the influx of reports suddenly stopped and visual observers disappeared off the face of the planet
I've seen Jupiter about 5 times this season, but still haven't caught the red spot
What are the odds of that!
Did you use a filter for the Horsehead? A UHC helps but H-beta is best, an 8" from a dark sky should catch it. The UHC won't work on the nebulosity around the Pleiades as it's a reflection nebula and not actually emitting any of the spectral lines that such filters isolate.
