G'day all,

 

With clouds and work interfering with my captures, I took a stab at reprocessing last year's capture of the Southern Beehive Cluster (NGC 2516). I've been getting reasonable results at ~30% capture scale with 30sec captures with a highly customized RawTherapee workflow inspired by Roger Clark's first cut with it. But for an open cluster, I was able to get good results at 100% sensor scale:
