Reprocessed Supernova remnants
Since my processing technique gets better and weather doesn't give any support, I have reprocessed couple of older images. There is now star colors added and other processing is tweaked too.
Sh2-223, 224 & 225
This image is a very rare one. Two supernova remnants are visible in a same three degrees field of view.
from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.
Star colors are mixed from the NB channels, Red=H-a, G=O-III and B= 85%O-III + 15%H-a.
Total exposure time is about 20h with a world fastest camera optics, Canon EF 200mm f1.8 with full aperture.
A special processing technique of mine is used to process this extreme dim data:
Star colors are mixed from the NB channels, Red=H-a, G=O-III and B= 85%O-III + 15%H-a.
Original version with technical details:
Simeis 147 aka Sh2-250
My second reprocessed image is a Supernova remnant in constellation Taurus.
Original image of this very dim and large object was selected as an Astronomical Picture Of the Day, APOD, by NASA.
