I managed to get 22 x 2-minute subs using the Canon 200mm prime lenses and the ASI 2600MC Pro OSC CMOS camera on beautiful Sirius last night. Given the bright Moon overhead I am very pleased at the final result. … Continue reading
I put together the 72 x 15-minute subs (UV/IR cut) and 30 x 20-minute subs (L-Enhance) taken on the 200mm lenses with the L-Enhance and UV/IR cut filters – and then took away all the stars to get this result.
I got another 8 x 20-minute subs last night (before we got completely fogged out) to go with the earlier 10 x 20-minute subs giving a 6-hour total exposure time. This is with the 2600MC Pro CMOS cameras and the … Continue reading
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.
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.
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
Another reprocess of the Rosette data – all the Hyperstar data was overlaid on all the Sky90 data using Registar and a mean/median mix.
The brightest star in the Northern Celestial Hemisphere.
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
