Barnard 175 - Cosmic Curiosities

In the constellation of Cepheus, a long pillar of dark dust (the Bok Globule, Barnard 175) terminates in a brilliant sapphire reflection nebula (vdB 152, Cederblad 201).

This image contains other curiosities, too. The long red hydrogen alpha filaments of a supernova remnant (SNR 110.3+11.3) appear to intertwine through the background. Embedded in the dusty pillar and showing a vibrant red, a forming star with polar jets of ionized gas interacts with the interstellar medium (Herbig Haro object, HH450). The inner pocket of the reflection nebula has some interesting arcs of material lit from within and is somewhat reminiscent of the Iris Nebula. I didn't have the FOV for it, but just off the lower right of the frame is an ancient planetary nebula that emits in Ha and OIII. We are peering through a fairly busy part of the Milky Way, but amazingly there are at least a couple background galaxies visible.

I found this image to be a particular challenge on the processing side. The dark nebula is exceedingly faint in luminance and the supernova remnant was even dimmer in hydrogen alpha emission.

If you ask me, this complex nebula looks most like a baby penguin looking skyward.

Enjoy!

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.
