rethinks

 I've been thinking about how and when to apply noise reduction. I hate noise reduction. Here are a few ideas with a mild de-noise on the linear image before processing. It seems to work a little better. Natural rather than plastic looking photos.

consecutive clear nights

 A week's worth of clear skies either side of new moon. Exhausted. Nocturnal. Tired. Whatever its called...

First time for a filter change. In the darkness. At 02:30 too. Had to refocus because the Moon and Skyglow doesn't focus at the same position as the L-eNhance. Ahhgghh! Then the flat frames. What a mess. Managed to rescue something...

All with the old faithful gso203 and vTEC571 cooled to -5º @ hcg100

fitzgibbon and roldan

 Colbayns. Miguel Blanes, a set of vinyl records, and this book.

An interview in Palma. On the headmistress's boat. Almost forgot. The G&T's at El Prat, waiting for the flight across the sea. Needed a few of those.

So as on all the best CVs, 1st. September 1984 to continues.

 Well, not all galaxies.

markarian's chain

 Not for lack of effort, as demonstrated in previous attempts.

Also, as previously, a fill in job until sunrise with m56. The ideal focal length for small clusters.

more starless

 Hopefully, normal service will be resumed after this. Promise. I had to get it out of my system.
