Sh2-230 in natural colors

Posted on January 26, 2022February 3, 2022

This image it’s a result of 18 hours of integration time using a Canon 200mm f2.8 lens, OpenAstrotracker mount, ASI1600MM-C and Astronomik filters.

Also, the final image was further enriched with 12 hours of additional old data from 2019 on Oiii and Sii regions.

The Sh2-230 object has a very large apparent size, extending at least 5° into a region already particularly rich in nebulae.
The object is mixed in with a number of other Sharpless objects in the heart of Auriga.
These include Sh2-229 (seen on the up right side), Sh2-236 (just below the middle), Sh2-234 and Sh2-237 (on the bottom). Also Messier 38 is on the left side of the image.
