About this object
This image shows a very dusty area in the Milky Way in the constellation Cassiopeia. The image is a cropped version of a much larger field of view showing the interesting objects around Sharpless 2-187, the red emission HII area below and right of center. Sh2-187 is part of a large molecular cloud complex and has many infrared sources within it indicating star formation. (From Galaxy Map) "This young (100-200 thousand years) star formation region is most likely ionised by a B0 class star and is surrounded by a 4600 solar mass molecular cloud. It is partially obscured by the Lynds dark nebula LDN 1317 and contains the infrared star cluster [BDS2003] 52". There are other molecular dust clouds surrounding this area including LDN 1316, 1323, 1323 and Barnard 22.
The image was taken at the Eldorado Star Party in Eldorado Texas during October 2020.
