This was sufficiently low when it got dark that I had to start cutting the hedge back to get at it with the 100mm refractor in the main observatory. This scope with a DSLR at prime focus framed it well. … Continue reading

Here’s Comet Jacques from last night. 20 one minute exposures stacked on the comet. There are some colour gradients in the background that I haven’t been able to correct, I possibly need need better flat fields. No trace of a … Continue reading
Here is the result of my Jupiter imaging early last night. Ropey seeing, but something salvaged. Two different presentations of the same data: the RGB shows truer colour, but the LRGB gives better contrast. … Continue reading
Seeing not so good as on the 10th, but as usual I’ve eked something out here using the LRGB process with L=R. Click to enlarge. … Continue reading
Here’s some further images from December 10, but the other end of the day. These were taken well before culmination, which was good because after midnight the sky, which had been stable for some time because of high pressure, fogged … Continue reading
I had a busy night; seeing was unusually good for this location. Ian Sharp reported exceptional seeing in Sussex as well, but Damian Peach, in a different part of Sussex, reported poor seeing, strangely. First row are RGB composites. Second … Continue reading
A couple of images from early in the apparition. Seeing not up to much. … Continue reading
Here is an attempt at narrowband imaging with the 10″ f4.8 last night. The light frames total 115 minutes. The palette used is R and L = H alpha, G = 0III, B = SII. Almost all the nebula information … Continue reading
Here’s my full disk from Saturday. Seeing was not that good. There’s a lot of scattered light. This is due to the blocking filter. I’ve been finding that my Lunt blocking filters have gradually degraded over time, and are no … Continue reading
I managed to catch an astonishingly fast-moving prominence here. I imaged it for 1 minute runs at 5 minute intervals, but really this was too slow, it was changing so quickly, that shorter runs might have been better. It was … Continue reading
