I wanted to make sure I had stacked the 38 x 40-minute subs of Pleiades data properly, so I went right back to the RAW FITS files and did it all again. I think I did stack the data properly, … Continue reading
A reprocess of a large amount of Cygnus Wall data taken on the Sky90 array.
A reprocess of very deep Sky90 data taken of M45 (the Pleiades).
I stacked each individual sub of this 38 subs x 40-minute stack of subs instead of stacking 4 blocks of subs together. This has given a far better SNR than my previous efforts. So this image is 25-hours and 20-minutes … Continue reading
This isn’t my deepest image of the Pleiades, but this dataset was taken over a couple of consecutive nights using the Sky90 array and the M26C OSC CCDs. This is 24-hours of total exposure time using 40-minute subs!
The above 6 images of the Double Cluster show this region at different scales and with the images taken on several different pieces of kit. The first image is a 4-frame mosaic taken with a Sky90 and M25C OSC CCD. … Continue reading
V1331 Cygni is a young star in Cygnus in the dark nebula LDN981. It is almost surrounded by an arc-like reflection nebula. I have just spent many hours re-stacking the 6-hours worth of 10 and 15-minute subs expecting to get … Continue reading
I like close pairings of red and blue stars for the striking colour contrast they give. Here’s a pair that don’t get much air-time, namely Tania Australis (red) and Tania Borealis (blue) which reside in Ursa Major. Just to the … Continue reading
A reprocess of a Sky90/M26C OSC CCD composite image of the Garnet star in the IC1396 nebula.
This is a 2-frame mosaic using the Sky90 array and M26C OSC CCDs. Centre-bottom is the bright star Epsilon Cassiopei, and above left is the asterism Greg’s Lambda.
