That's a tiny one. Too small for my normal seeing so he isn't even on
my to-do list. A quick check of the observing logs I've put on computer
don't show I've even logged it visually. But I didn't check the early
logs which haven't been put on computer. Guess I should at least
eyeball it!

Third character is a zero rather than a capital "Oh".

Nice small object. At least it can be distinguished from a star. It would
probably be a good target for a Ha:OIII:OIII image, the nebula would stand
out from the starfield by it's cyan colour.
