Visually, NGC 6891 seems fairly simple. I can only see some very small knots of H-alpha. One of them is easy to spot. It’s a very small, red dot near the left edge of the outer halo of material. I almost cleaned it up, thinking it was a cosmic ray.
North is NOT up.
Hubble data is public domain, but I put a lot of work into combining it into beautiful color images. The minimal credit line should read: NASA / ESA / J. Schmidt
