SH2- 232
There is another version of SH2-232 done in 2022: HERE
Sh2-232 (centre), Sh2-235 (bright area), SH-231 and the smaller SH2-233 to the left, are large faint regions of Ha-nebulosity in the constellation Auriga. But they aren’t the only objects in the image. The small oval structure just above centre of Sh2-232 is the planetary nebula, PN G173.5+03.2. The estimated distance to Sh2-235 is 5,870 light years. Not sure about Sh2-232, but it is likely similar to Sh2-235, since they appear to be part of the same cloud of hydrogen. For reference, this field is only about 3 degrees (6 moon widths) from the more famous Flaming Star and Tadpole Nebulae.
This area is not imaged very often - it really is quite faint. I found it quite hard to process the data and although, not quite the colours I had intended, I am quite pleased with the detail. (Note that there is little or no OIII showing up in 4.5 hours of subs.)
