Sue French included Palomar 11 in one of her Sky & Telescope columns and described it in her 14.5".
At 245x [in my 14.5"], this low surface brightness globular appears about 3' x 2 1/4' aligned NE to SW. It looks mottled, and there are a half dozen superposed stars, at least some of which may be foreground objects (The brightest stars of Pal 11 itself are red giants with apparent mags of around 15.5). A skinny triangle of 11th- and 12th-magnitude stars sits off the NE edge.
I've read a few observations using a 10" from dark sites, including this one from Susan Young at her Bortle 1 site in the Kalahari Desert:
I must confess this one surprised me. I was assuming that the glob’s large size would render it impossible to see. But there it was – a small and very faint glow that didn’t show any central concentration. Averted vision gave it a very, very faint mottling texture that quivered; no stars, simply the very faint quiver of mottling. Very unusual view.
What have others found?
