Sometimes called the “Cat’s Eye Galaxy,” this is M94 – about 16 million light years away in the constellation Canes Venatici. You can barely see its faint outer ring surrounding it here, as well as several very distant background galaxies.
It’s notable for challenging our understanding of the universe – it appears to have very little dark matter for some reason. We can’t explain how it formed without it, or how it may have lost it.
Imaged over the past couple of nights, with a total of about 13 hours of exposure time.
