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. Arne
