A starless Cygnus Wall region.
I used Registar to combine a number of images that included the Cygnus Wall, and the used Russ Croman’s StarXTerminator to remove the stars.
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.
Only 2 x 20-minute subs with the 200mm lenses – but it shows the way to proceed with this one. Obviously a 20-minute sub is way too long for M42, but just fine for the Horsehead region. So a fair … Continue reading
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.
