Sharpless 224 and Sharpless 223 |

| According to www.sharplesscatalog.com, both
Sharpless 224 (the very interestingly-shaped object on the left)
and Sharpless 223 (to the lower right) are both supernova
remnants, so this image covers the debris of two ancient
colossal super stars that literally went out with a bang
thousands of years ago. Both objects lie in the constellation
Auriga, and both are very faint nebulae that required a bit of
exposure to bring out the details and colors depicted here. I
was pleasantly surprised to pick up both SII and OIII data, so
I'm representing the image in many of the popular ways these
targets as depicted, as well as an H-alpha/OIII blend that
brings out the difference in structure of the ionized gases
represented. I am not sure about the extent of the OIII data
outside of the outer extensions around Sharpless 224. There was
a glow in my OIII data, which I decided to preserve in the
Ha/OIII representation in case it's real data. |
