Description

Here is a ridiculously faint planetary nebula in Cassiopia - Sh2-176 (15+ mag) . Almost 5 hours exposure with the E160 and QHY22 in narrow-band - imaged from White Bear Township.

I combined S2, O3, and Hb data (20x180s subs) for RGB stars. Only Ha (23x300s subs) had nebulosity in it and was blended into the red channel.
