Sh2 280 (Jerry Yesavage)

Sh2 280

New data with traditional blue and gold processing.

Prior Ha effort:

Sh2 280 H-Alpha RGB

From GalaxyMap:

The HII region Sh 2-280 appears to be located near or at the edge of the Rosette molecular cloud. Avedisova suggests two possible ionising stars, the O7 HD 46573 and the B0 III giant HD 46847. A 1981 paper also states that the ionising star for this HII region is HD 46573. HD 46573 may be an outlying star of the NGC 2244 cluster, which ionises Sh 275, the Rosette nebula.

GENERAL NOTE ON SHARPLESS2 OBJECTS>>>>>>>>>>>>>

There are 313 Sh2 objects. As of the date of this image I had imaged all 313 (100%).

Some of the challenges with this series are FOV size and low declination:

There are 11 too diffuse/large to image well with my set up (Sh2 111, 117, 122, 131, 132, 145, 178, 218, 230, 268 and 310). I have imaged the first 6 of these mostly in the Nikon Wide angle shot referenced below and 178 and 230 as part of other images.

There are 5 that are never above 14 DEG (Sh2 2-6) but as of 7/12/21 I can get these now with pier upgrades and the images are completed as best as I can.

Many were taken with my old Tak 180 ED, which had a wide field of view, but was replaced with my Stellarvue 130, which is more narrow field. I have also taken two very wide field HA images with my Nikon D800 and a 50mm lens. I transitioned from my CCD SBIG 8300M to a CMOS ZWO ASI6200M Pro in September 2021.

The first one was taken on December 23, 2013 and the series completed October 17, 2019.

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.
