But I recently had the eyeballs in for a tune-up and lube and I'm
reasonably confident the corrective lenses are nicely dialed in.
Although I still cannot locate an opthamologist to grant an after
midnight appointment so as to get the best possible correction for
astronomy use.

One thing is to get your doctor to prescribe a pair of "astronomy glasses."
The difference between these and your regular prescription is that these are
focused at infinity (instead of some closer point as is done normally).
