Description

This is from a night shortened by RFI issues with my old dew controller. Limiting magnitude was 6+. Transparency was excellent.

Version A: The lesson here is "don't process images on three hours of sleep."

Version B: Mostly a better handling of the L data. Dialed down the star size reduction step from Images Plus that does a good job on stars, but tends to make nebulosity lumpy. Also upped the contrast and saturation.
