Description

Version2 : enhancement of the HII modules !
------------------------
My version of this great galaxy NGC2903 in classical LRGB but also with Halpha .
Halpha really adds a good balance of the colors with its HII nodules well defined , without tweaking the cursor ...

NGC 2903 is a field barred spiral galaxy about 30 million light-years away in the constellation Leo. It was discovered by William Herschel who cataloged it on November 16, 1784. NGC 2903 has a very high rate of star formation in its central region. NGC 2905 is a bright star cloud within this galaxy
