Amen to that!!

I have seen huge drift XY and Z with poor temperature control.  An AC or
Heat vent blowing on the system can create havoc on imaging and
deconvolution.

We had a case that we named "dot boogie"  where a bead would "boogie"
out of the field of view (60x) and boogie back in depending if the AC
was blowing or not. Z was also "interesting".

Cheers,
Tom

One suggestion: be very careful about how the air conditioning is set
up.  Depending upon (1) the temperature differential between ambient air
and the air conditioning outflow, and (2) the placement of the air
conditioning duct relative to your microscope, you can produce VERY
noticeable (--like 3 um) shifts in focus/stage position.  The resulting
3D reconstructions look pretty odd.
