SH2-106 | A Planetary-like Emission Nebula in HaLRGB

Sh2-106 is an odd nebula. It is very small and features the hourglass shape typical of polar jets. But it is a newborn star merely 100,000 years old rather than a large, old red giant as typical of a planetary nebula.

The star is ionizing the gasses that surround it, presumably the gasses it formed from. And nearby dust is reflecting its light.

The hourglass structure measures ~240 pixels in my image. At a .73" image scale that is a little under 3 arc minutes on the long side.

Here I have combined Ha into the Red channel and the Super-luminance for an HaLRGB image. Luminance and RGB were combined to a Super-Luminance and then deconvolved in PI. The Ha Channel was also deconvolved in PI and the two were meaned. HDRMT was then applied to reduce the very bright hourglass portion. Ha was added to the Red channel. Noise reduction via Topaz Denoise AI. Stars were reduced with a minimum filter in PS.

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.
