Trumpler 14 and the Keyhole Nebula

 

Previous versions of the above image won the Deep Sky section of the CWAS David Malin awards in 2016

and gained the NASA "Astronomy Picture of the Day" (APOD) on May 27th 2016.

The image above has been reprocessed with insights based on Dr David Malin's critique on the awards night.

It now shows the hot blue stars of Trumpler 14 (and others within the nebula) with improved fidelity, along

with reduced processing artifacts (that were unintentional) seen in earlier iterations.

I hope you enjoy the view!
