Hubble Variable, Cone and Fox Fur Nebulae (Wide Field!)

Located in the constellation Monoceros, the Unicorn, 2,700 light-years away, you'll discover several areas of interest. This 2.5 deg widefield view highlights a few; the Hubble Variable - NGC 2261(lower right), discovered by Edwin Hubble who reported this nebula appeared to change its shape in a series of photographs taken over 8 years. It is now known that these changes are actually caused by variations in the variable star R Mon, which illuminates the nebula. NGC 2264, containing the Cone Nebula (lower center) which contains hot B-class star about 3500 times more luminous than our Sun, is located just beyond the tip of the Cone nebula and the Bok Globule in the tip of the cone may be creating a stellar winds that energizes and shapes the nebula. The Christmas Tree Cluster (center) with its brightest star (S Mon-center) ionizes the fine gases surrounding the cluster; causing the stellar winds which are visible throughout this image. The gentle arcs just south of S Mon highlighted in orange and blue near the center of the image are Herbig Haro objects, jets of gas from protostars embedded in the nebula, and the just to the right of S Mon is the Fox Fur Nebula, ionized primarily by S Mon and named so by its appearance of a fox stoll.

This image was created by combining emission-line images in Hydrogen-alpha (red-orange), Oxygen [O III] (light blue) and Sulfur [S II] (blue-violet) in my backyard (San Diego, Ca) over several nights.

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.
