Description

Sh2-188 - Shrimp Nebula.  I processed the nebula without stars and then added RGB stars later.  This seemed to be a difficult target for me to process and I'm not sure why.  My master files were very noisy, which is unusual for 26 hours of integration time with a very low noise QHY600M.  I used StarXTerminator, NoiseXTerminator and BlurXTerminator along with a ton of different masks to get this result.  I had another 12 hours of SII for a SHO image but I couldn't get things to work for some reason.  Lots of color and other strange artifacts.  The OIII "topnotch" is interesting along with the detail, structure and Ha nebulosity below the main core of the nebula.
