Hubble palette image of this region around the trapezuim’s four bright stars.

Having a go at this before my second target of the evening gets high enough in the sky.

Difficult to process with the bright central region and the fainter outer parts. Used a photoshop layer mask to help.

Also Used an unsharp mask to highlight the dust lane detail.
