Hello everyone!
Armed with my DSS method of compensating for the reduction in the green channel from my UHC-S filter (debayer ratio R:G:B of 0.7:1:0.7) I went back and reprocessed some M83 data from May last year. I'd always been disappointed that I'd never been able to capture the yellow from the older stars in the central core of the galaxy. In fact most of the galaxies that I'd imaged through the UHC-S filter had looked anaemic to say the least!
So here is the reprocessed version using my new method - the data was captured using a QHY8L through an 8" newt. 33 x 5 minute subs. I think you'll agree that the colours, although more vivid, are more in keeping with what you would expect compared to my last repro of this data. Well I think so...
Cheers,
Mario
