Sh2-205 & Sh2-206 Emission Nebulas in SHO

Recently I captured Sh2-206 (NGC 1491) with my 152mm refractor. I wanted to get my wider field Stellarvue SV70T out to capture both Sh2-205 and Sh2-206 together. Sh2-205 (to the right) is so incredibly faint. I had to really pile on the integration time.

Sh2-205 is a large nebula on the border of the constellations Camelopardalis and Perseus at an estimated distance of approximately 3,200 light-years. Sh2-205 is commonly referred to as the Peanut Nebula. The nebula is classified as a HII region and is divided into 3 sections identified as SH 149.25-0.0, SH 148.83-0.67, and LBN 148.11-0.45. HII regions are typically the site of active star formation.

NGC 1491 (also designated Sharpless SH2-206) is a bright emission nebula and HII region, located on the edge of a vast cloud region of neutral gas, about 10,700 light-years away in the Perseus arm of our Milky Way galaxy. The stellar wind from the O5V 11.2 magnitude star (BD +50 886) at its centre is forming a blister in the gas clouds immediately surrounding it while also eroding the gas clouds.

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.
