Description

Added SII data to my previous Ha and OIII. Spent quite alot of time dealing with several processing challenges. One of the most difficult was the seeing for the OIII and SII data was much worse than the Ha data. This required shrinking the stars considerably in the OIII and SII to avoid color rings around stars. Another challenge was the OIII in this area is very weak compared to the Ha and SII so it is hard to effectively blend it in and have it show up.

Hard to find many tricolor narrow band images of this area!
