Description

LP Conditions here rarely support decent RGB capture, tried this on what was a good night. Added an Ha channel to give a bit more pop

I like the subtle blues and browns background colouration in this more than the cocoon itself (which is tiny at this image scale).

RGB 6 x 600s per channel, Ha 8 x 1200s.
