The water tank is only 2/3 full, but little or no rain predicted, just steamy cloud, so we thought we'd post what we had: 10 hours of NGC 300 in monochrome. (Trish said that since it was mono, I could do the colour balance on this one).

We're quite pleased with the sharpness of the myriad OB regions - lotsa dots - presumably not individual stars much as we'd like them to be - tracing out the spiral arms - and with the detailed shape and form in many edge-on spirals in the background.
Toward ten o'clock and about 80% of the way out there is an edge-on spiral with an almost implausible tidal tail hanging down*. Pleased to report that it is also seen in Greg Bradley's beautiful colour shot, and is therefore not an asteroid trail, but is sadly out of frame in Ray/Shiraz's stunning version.
