separating color channels
Posted: Wed Oct 23, 2019 1:10 pm
I have StarTools 1.4 and I have been using it for about four years.
I tried an experiment with my Fuji X-A1 DSLR, mainly to deal with light pollution. I took a series of 120s light frames with an Ha. Then I took a series of 120s light frames with an O3 filter. I processed both sets together as two "groups" using DSS and got a single *fits file output. I used StarTools to process as if the *.fits was just the normal output for a DSLR camera.
I was imaging IC 1805 (heart nebula). Blurry but at least infinitely better than light frames that get washed out with LP after 20 seconds.
Somebody suggested (on another website) that I try to separate the RED from the RGGB data and process it separately and then do the same for the BLUE.
Can StarTools do that ... basically creating an image file that has only pixels corresponding to the "R" in the RGGB matrix ???
BABO
