Description

I think we've all had data that resists giving us what we had envisioned for the image we are creating. These were that type of data. I have been processing and reprocessing these data for about a week, attempting different approaches to accomplish the look I was striving to achieve. After a while, I think you stare at an image so long you just can't see it anymore. So, time to post and get some feedback from my colleagues. There are three different processing approaches represented. Version A is a NB RGB approach using the HST palette. Version B is a standard HST narrowband approach. Version C is a NB RGB approach using a "natural" NB palette to create more natural stars and color representation. So, which one works best for you? Thanks for any comments and suggestions.
