Description

IC410 in SHO (with RGB stars), as seen while gazing upward through the pond scum.

I collected enough OSC photons for a separate natural color image eventually, but herein used the OSC data only for RGB stars.

Description: Brightened rev. C a bit and decided that I like the vertical format most. Revs B, C and D are more respectful of black levels and the histogram but for the Final version I crushed these intentionally for pond-bottoms aesthetic effect.
