There are other calibrated areas; the question is whether they
are "standards" quality.  For example, Peter Stetson has a whole set of
clusters:

Other standardized clusters include NGC7790 and M11.  However,
unless you know what you are doing, I'd suggest keeping with
Landolt standards if possible.  There are several fields, such
as those near SA110_503, where multiple stars will fit within
a CCD field of view.
