you have pin point stars to all corners.

I take it you didn't use BlurXterminator ?

Thanks Allan. I did use BXT on the luminance channel. Whilst I didn't actually capture luminance data in this instance, I did create a synthetic luminance channel by integrating each of the RGB masters into a single greyscale image. I then processed the synthetic luminance for additional clarity and used BXT as part of that process.

Why didn't I just capture luminance data I hear you ask? The answer to that is I was trying to capture as much RGB as possible in the relative short time that M45 presents itself at an ok elevation. Given its northern position I would rather just grab as much RGB as I can and then work with a synthetic luminance for bringing out the structural details.
