Description

Faint nebulosity around NGC 6820. The area glows with Ha light wavelengths but Oiii and Sii are really faint.

I tried HSO which came out mostly red with Ha in the red channel. SHO came out as shades of green. I ended up using the SHO combination with APP Hubble 3 color blend, PI for decon, stretch and denoise. Then used PI and PS to adjust colors and brighten image.

Five minute exposures of about 6 hrs each for three nights.
