Description

The oft-imaged Cygnus Loop, shot with my full-spectrum mono Canon 60D, AT60ED w/ 0.8x reducer, and CEM40. I used 6-nm Astronimik clip-in filters for H-a and OIII, and followed up with my H-a modded Canon 600D for star colors.

This was shot as a 2-panel mosaic with 4 sessions going towards H-a, 2 sessions for OIII, and 2 more for RGB. 300-second subs for narrowband and 60s subs for broadband at ISO 800. Each data set was calibrated and stacked in APP, and then aligned and composed as HOO in APP. I tried this in PI as well, but the APP output was surprisingly clean compared to PI. The HOO and RGB versions were further processed in PI and finished in GIMP.

I might have overdone the color. C&C welcome and appreciated!
