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
Here’s some images of a rapidly changing nearly-detached prominence on the Sun’s eastern limb. Taken with at a focal length of 1440mm with a 100mm refractor, double-stacked with Lunt 50mm filters using home-built adaptor, plus 1.6x Barlow: a nice long … Continue reading
Nova Delphinus imaged with a Canon EOS 400D and old Hanimex 28mm SLR wide-angle lens. There was some interference from a gibbous Moon (Click to enlarge). … Continue reading
Playing solar catch-up, here’s the Sun in H alpha and infra-red on the same day in June. The spot group shown in the IR image corresponds to the active area right of centre. Seeing was poor. (Click on images to … Continue reading
Dealing with a backlog of observations here: some nice sunspots imaged with a 5-inch SCT in IR 804nm. The image is not rectangular because I cut out a sensor dust mote. (Click to enlarge) … Continue reading
