Description

got only 1 SII frame last night, so did something stupid. calibrated it, did cosmetic correction and muredenoise, then linear fit it to the Ha frame and multiplied the Ha frame by the single SII frame and used that as a fake SII channel in an SHO mapping. didn't come out quite right but i still like the colors. the stars looked pretty bad so i used straton to remove them.

did a little touchup in photoshop but i should probably work harder on the star removal.
