The idea is to take a photo of a bright deep sky object and the surrounding region. The result should be an impressive starfield with something bright to give the image some punctuation. This does not always work.
In the previous image, Mirfak and Mellotte 20, the idea worked pretty well. Bright stars highlight a rich Milky Way starfield in Perseus. In this next image I processed the plan did not quite work as well. The target is the bright open cluster M39. At magnitude 4.6 I thought the cluster would appear brighter against the surrounding starfield. In this case the component stars are somewhat dimmer, thus the effect is not as dramatic.
There is still a lot of material to process from OSP, we shall see what worked and what did not.
