Sh2 86 and 87 (Jerry Yesavage)

Sh2 86 and 87

An new ZWO view expanded with H-alpha but did not have the other NB filters worked out before it set this winter.

The prior images from the collection:

Sh2 86 from Deep Sky West

Sh2 86 H-Alpha

From GalaxyMap:

Sh2 86: The HII region NGC 6820 contains the radio source W55 and is ionised by the star cluster NGC 6823, which is part of the Vul OB1 association.

Sh2 87: This massive star formation region is associated with a 7000 solar mass molecular cloud and many sources in the far infrared.

You can see a good visual image of Sh 2-87 here and the Spitzer space telescope infrared view here.

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

There are 313 Sh2 objects and I have imaged all one way or another.

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

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

FOV: 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.

DEC: 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.

EQUIPMENT: 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.
