NGC 2170, the Angel Nebula in Monoceros

A beautiful dark nebula pattern in front of faint HII emission, joined by some colorful reflection nebulae around blueish and reddish stars - NGC 2170 is also called the Angel Nebula, which in my eyes is an appropriate description. Closeby lie more reflection nebulae NGC 2182 and NGC 2183. The objects belong to and are embedded in the Mon R2 giant molecular cloud, ~6500 LJ distant.

I was really impressed when i found this motif in an APOD, and immediately put it on top of my to-do-list. However, i underestimated the faintness of this object, a dark site is quite essential to capture it successfully. I partially tried to compensate this using a huge stray light cap on my terrace, but in SW direction this doesnt work satisfactory.

Since i actually got about 2 hours per session, before the object started disappearing, my side project NGC 2264 collected more and better data. Weather turned cloudy, and in three weeks the exposure window will be even smaller. So i'll reconfigure my scope and threw in all of my knowledge to process the image as-is. Still a bit short of subs. Hopefully i can add more data next year!

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.
