Astronomy Image of the Day
I don’t know how many hours of data using the Sky90 array on the Pleiades (M45) star cluster. Probably in excess of 20-hours.
Heart Nebula – Complete Reprocess
Just did a complete reprocess of the Heart nebula with star reduction as I felt I could do a better job on it. I think it is a marginal improvement over my last effort.
Yet Another Pleiades Reprocess
Once you bring Russ Croman’s Star XTerminator into your processing, there’s about a million different ways to go forward. Here’s yet another way.
This is a star reduced Pleiades image (reprocess) using a 30-hour dataset (40-minute subs) taken on the Sky90 array with M26C OSC CCDs.
SAO 132035 an S-Type star (s 4,1) Just East of Rigel
The star at centre is SAO 132035 a (very red) s-type star lying just to the east of Rigel. As per usual there’s a nice blue star close-by to the bright red star
Reprocess of all Hyperstar on all Sky90 Data – Median Mix in Registar
Another reprocess of the Rosette data – all the Hyperstar data was overlaid on all the Sky90 data using Registar and a mean/median mix.
Arcturus – the Eye of the Bull – from 2013
The brightest star in the Northern Celestial Hemisphere.
Sirius – The Brightest Star in the Sky
Out of all my bright, single star images, I think this one is my favourite. Sirius – the brightest star in the sky. Two-frame (vertical) mosaic with camera in landscape mode. 3 x Sky90 refractors and 3 x M26C (non-Trius) … Continue reading

Star Reduced Deep Pleiades
Star reduction does a nice job on a deep Sky90 image of the Pleiades.
Composite IC410/IC405 Nebulae in Auriga
And a last reprocess (maybe) on this one too. This is around 12-hours of Sky90 data added to 10-hours and 40-minutes of 200mm lens data giving a composite image of the IC410/IC405 region in Auriga – a total (composite) exposure … Continue reading
