I think that all need to be flipped as they are the mirror image. Here is one I did in late March.

You can see my version lacks the delicate detail in Monte's data due to different optics . But it shows more dynamic range.
I think if Monte tried series of exposures each time doubling the exposure time EasyHDR would then get all the dynamic range of this region. It is a difficult region to image.
I would be interested to have a go at a set of RGB's taken this way.
