We have had some snow down here in the south. Good for the skiers! Clear frosty nights lined up now for the next few days. A pity I couldn't get rid of that moon!
The very few open clusters I've done, I've tended to process them to just show the cluster stars as isolated blinding jewels against blackness.
You've taken a completely different tack, showing them in context. And from your image one gets some sense of how a rare and short-lived, bright blue OB cluster star can be ten thousand times more luminous than the billions of far longer lived run of the mill faint orange fellows in the background.
