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.
Looking at some old emails from way back in 2015 now, 8 years on, the idea I had back then seems better than ever to me now. The reason I wrote it off back then, is that I mailed David … Continue reading
Another oldie from 1998 – this time dragging out the fractals hiding in complex power iterations.
Just putting these results from way back in 1997 up here so I know where to find them.
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.
When I downloaded Russ Croman’s “Star XTerminator” for a free trial – one of the first images I tested it on was the JWST image of the Pillars of Creation. So I have no idea why it took me several … Continue reading
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
