Sh2 53 (Jerry Yesavage)

Sh2 53

Two to go in the series. In checking my collection, this one was missing so luckily I could shoot last night. This is one night's imaging. Great camera.

From GalaxyMap:

Sharpless notes that Sh 2-53 consists of "About six detached portions". The area is prominent at both radio and infrared frequencies.

Avedisova places the nebula in the complex star formation region SFR 18.18-0.30, which includes 4 molecular clouds, a methanol maser and at least 4 additional HII regions visible at radio and infrared frequencies.

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

There are 313 Sh2 objects. As of the date of this image I had imaged 311 (99%).

Here is the scorecard:

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. I will do the rest at least once as they come into view this year. I missed 304 and 310 last year running out of time. So there are these 2 more to do here.

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.

The 2 remaining all are in Expert Scheduler waiting for them to pass by. They are all higher elevations.

The first one was taken on December 23, 2013.

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.

This is my collection:

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.
