Description

Although the original intent of obtaining RGB data was simply to collect 20 minutes  on each filter to be used for RGB stars, we were treated to an unexpectedly clear night nearly all night, so the RGB image is from a single night of 60 second subs. After seeing that detail in the RGB image, the Ha data from previous sessions were blended into the red channel for the HaRGB image.  Not sure which I prefer, but I think it is the RGB image in part because the underlying stellar colors are more apparent.
