M22 is right in the thick of it, not far from the galactic center of the Milky Way. As such, it has lots of company. One particular planetary nebula proves a worthy adversary through 10- to 14-inch scopes: IC 4732. IC 4732 lies just 1.4° north-northwest of M22. Cataloged at magnitude 12.1, its tiny disk is difficult to pick out from the mob of field stars -- difficult, but not impossible.

Ouch. That one's going to be a real challenge from my latitude.

Yikes! Well, I have the OIII and a very big scope... I'm wondering if an eyepiece spectroscope might help---or not?    Tom

I think a spectroscope would definitely help.

Well, whenever I can have some clear sky, I will attempt this with my C11. My OIII filter may help too.

Hmmm....my astronomy club's star party is at the end of the month.  I was planning to take my 6" refractor.  Might be too light for this object, but I'm gonna try.

I can't recall ever seeing this planetary nebula before but my observing buddy Tony Donnangelo logged it years ago with his 14.5" Starmaster Dob.
