Description

I captured about four more hours of RGB and Ha data on M33 this past October, and combined it with the RGB data I captured the previous year. This is the result. It is stretched somewhat less than my earlier effort, and although the nebulosity is more subtle, I actually like this rendition more. Triangulum is faint and I have to believe that any appreciable distance it would appear to be a structured mist more than a bright gleaming oval ... but that's just my interpretation.
