Lobster Claw, Bubble nebula, Dormouse Cluster, and Northern Lagoon Nebula

This is a particularly "action-packed" part of the sky! One object in this image, the Herbig Ae/Be star EM* MWC 1080, I was lucky enough to notice was showing up in the LRGB I was taking for star color, so decided to grab some more broadband. I'll have to re-visit this when I get a longer FL scope, as it has some interesting morphology!

This was a challenge to process since there's quite a bit of high dynamic range content. It was too easy to lose detail in the Northern Lagoon and Bubble nebulae when trying to bring out the Lobster Claw. So I tried a bit of selective stretching (basically, Photoshop's HDR tool, but with different global stretches applied). I'm pretty happy with how it came out, though will need to also revisit the Bubble nebula, as the OIII data was basically washed out with the strong Ha signal.

The refractors!

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
