Something has caused stigmator shift bad enough to kill
resolution. It may be the shields I installed over Christmas,
as nothing else was done.....

Re-adjusted stigmator centering and all's well. Remember:
do not align stigmators, just stigmate. It looks like someone
adjusted the alignment by mistake. Resolution looks great
at 5KV up to 250,000X, so if you have problems, come get
me!
