Description

From GalaxyMap:

Also called

LBN 784

Sh 2-228 contains the infrared star cluster [IBP2002] CC01. The 1800 solar mass cluster is 1 to 2 million years old, and the surrounding field stars about 5-6 million years old.

Acquisition Note: I had 8 1800s HA images and they looked much worse that the 1 (ONE) 3600s image. I got rid of the hot pixels with CosmeticCorrection, and that was it.

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 and those below 70 and above 283 are generally too low on the horizon for me to image... this leaves me 213 that are feasible... and I have imaged all of these but 17. 13 of these are too big for my system. So 2 to go: (262 and 279).

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.

This is my collection:

Sharpless2

Please note there is also a Sharpless2 Group with now more than 1000 examples.

Hope you enjoy these obscure but interesting objects...
