Description

This one is very very dull. No signal in 4h of HA.

From GalaxyMap:

Sh 2-286 contains the infrared cluster [BDS2003] 88 and appears in the direction of the molecular cloud [MAB97] 217.38-1.38.

Russeil concludes the Sh 2-283 to Sh 2-286 are all part of one star formation region located in the Milky Way's Cygnus (Outer) arm.

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

I have been on a project for several years now to image all the Sharpless2 Objects that I can see from my location near San Francisco. I chose these because they are visible in light polluted areas. These objects generally represent left over Hydrogen along the edge of the Milky Way that has gotten molded into interesting shapes.

There are 313 Sh2 objects.

As of the date when this image was posted:

I had imaged 243 (78%).

There are 11 too diffuse/large to image with my set up.

There are 6 that are never above 14 DEG elevation at my site and are too low for my 17 DEG min due South.

This leaves me 53 potentially still do-able and most are in Expert Scheduler waiting for them to pass by.

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.

This is my collection:

Please note there is also a Sharpless2 Group with now more than 1500 examples.
