Reprocess number 2 for today and another 2-frame mosaic from the 200mm Canon prime lenses and the Trius M26C OSC CCDs. This time it is Procyon (bottom left) and Gomeisa (top right) which make up the constellation Canis Minor. Approximately … Continue reading
Another reprocess – this time of the 200mm Canon prime lens data (with Trius M26C OSC CCDs). This is a 2-frame mosaic of Arcturus – so this is a BIG field of view. Around 4-hours of 5-minute subs in total. … Continue reading
A reprocess of some old 200mm lens data using the Trius 26C OSC CCD camera. This is 22 x 10-minute subs on the Tarazed/Barnard’s “E” region. This year I will try to get a 2-framer of this region including Alshain … Continue reading
Quite some time ago I wrote up a piece on how a vertically oriented mirror laterally inverts an image (it doesn’t by the way). People quite often ask, if a mirror inverts laterally, then why doesn’t it invert vertically as … Continue reading
Here is a composite image of M31 comprising 2 sets of Sky90/M26C OSC CCD data.
Now this is an odd one. I just got a request to purchase an image of Arcturus that someone had seen on the New Forest Observatory website. Looking at the image it looked better than more recent 2-framers I’d done … Continue reading
From 18/01/2015 another Sky90 array image using the M26C OSC CCDs, this time open cluster NGC1817. 12 subs at 20-minutes per sub or 4-hours in total.
Image taken 24/01/2015 on the Sky90 array using the M26C OSC CCDs. 30 subs at 10-minutes per sub.
Mu Cephei sitting at the top of the bright emission nebula IC1396. A Sky90 array image using the M26C OSC CCDs and 51 x 4-minute subs. Image taken on 04/12/2012.
From 09/02/2015 using the Sky90 array and M26C OSC CCDs this is M44 – the Beehive Cluster. 29 x 5-minute subs and the Akira Fujii effect has been applied to bring out the cluster.
