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.
I just did a quick reprocess on this one and it looked nice enough to re-post. This is the famous Double-Cluster in Perseus, with the less famous Stock 2 (the stick-man lying on his side at top right). A 2-frame … Continue reading
I just found another 6-hours of 40-minute subs of M31 taken with the Sky90 array, and I added this to the earlier composite. You can see the result above and it is virtually no different from the previous result. I … Continue reading
I sent a friend a low-res version of M31 and they asked if they could have the hi-res version to print out and put on their wall. Now it gets embarrassing – can’t find the hi-res version anywhere. So I … Continue reading
