I really like doing these open clusters. Something new while I work on getting geared up for galaxy season.

Yes, I did add some spikes. I know it is controversial but for me, especially with open clusters I think it adds a lot to the image and accentuates the brighter members of the cluster.

I still feel like I have some bloat. Perhaps the 60s exposure time is still too much with this ASI183C. But I had great guiding and careful focus.

Less processing is most times a good thing... There is some nebulosity in this image that I processed out of the first iteration.
