John,
from memory it was fairly faint and averted vision was required to confirm the ring shape. Not sure I remember what power I was using at the time, but most likely I was at 100x to find it (19mm Pan) and 145x (13mm Nag) and 238x (8mm Rad) to observe it. Really going from memory here, but I do remember some relatively "bright" stars in a line in which the nebula was situated which may make it harder to see the nebula.
It is significanly fainter than the ring nebula and I can't remember the apparent size, but it isn't huge. I will read Hartung's when I get home and see what he said about it.
edit - just found this pic done by Scott Alder that gives you a sense of how faint it is:
