I'm not sure what to make of this one. I find it very difficult to make a star cluster stand out and "shine" and any processing feedback on this would be appreciated.

This was a fair size of integration for only ~40 minutes - 484 x 5s calibrated and stacked in APP then processed in PixInsight.

Not a typical target for the Samyang 135 (@ F2 in this image) but when you're dodging clouds, you take what you can get.

Description: For better or worse, reprocessed and left at full resolution this time. Thanks @Thilo and @Daniel Erickson for feedback. I couldn't pull out many of the fainter NGC objects highlighted in the plate solved image.
