This is another reprocess of old data, this time it’s the mighty Merak in the constellation Ursa Major. This is a 4-frame mosaic using the Sky90 array and the M26C OSC CCDs. Total exposure time is 16 hours using 10-minute … Continue reading
Another reprocess of old data. This time it is the Heart nebula. A 2-frame mosaic taken using the Sky90 array and the M26C OSC CCDs. The upper half of the image is 24 x 20-minute subs and the lower half … Continue reading
Another reprocess of old data – this time it is reflection nebulosity NGC6914 in Cygnus. This is 51 x 20-minute subs or 17-hours of total exposure time on the Sky90s and M26C OSC CCDs.
I found another dataset containing 9 x 40-minute subs for the Pleiades. I added these in but it didn’t seem to add much to the image so I think I’m in the diminishing returns region. Data was acquired on the … Continue reading
Some more reprocessed old data, this time it’s IC348 in Perseus. This is 10 and a half hours of data in 30-minute subs using the Sky90 array and the M26C OSC CCDs.
Going through the old data I found I had taken the same region of M45 (the Pleiades) over 3 different nights. The data turned out to be 21-hours worth of 40 and 20-minute subs taken on the Sky90 array with … Continue reading
Another reprocess of old data, this time it’s Carbon star U Cygni taken with the Sky90 array. This image is 39 x 10-minute subs. U Cygni is the small very red star towards top left lying just below a white … Continue reading
Another reprocess of old data – this time it’s Gomeisa in Canis Minor – 36 x 10-minute subs on the Sky90 array went into this one.
Another reprocess of old data. This time it’s Mizar & Alcor in Ursa Major. 21 x 10-minute subs on the Sky90 array for this one.
Here is the full-frame (uncropped) version of Hind’s Variable nebula.
