Description

I had difficulty getting a decent image of this star cluster with my vintage 8" LX200 SCT.    As is often the case, I was in a hurry to get things set up after work and didn't check collimation (it was out from having moved the scope several times).  Poor guiding on a low target also didn't help.  The end result was distorted stars whose shape could not be improved with conventional deconvolution methods and the new BlurXTerminator tool, no matter how many variations of %sharpen stars or %halos. PixInsight's HDRMultscaleTransform process helped bring out some of the details in the core, but  the final image still looked bad up close.  That's why it is not a stand-alone image, but is inset within the wide-field image collected earlier in the year using a RedCat51.
