Hi
I was warned against silicone grease in microscope since it has affinity to
glass  and tends to spread around.
At the end I wrote to a microscope service and repair company located in
Poland
They recommended this grease.
GRIZZLYGREASE No. 3
https://www.lubcon.com/en/products/greases/grizzlygrease-no-3/#
I was not able to get it but I think G-1/3 will do the job. It has 175 C
working temperature maximum and no dropping point. remainings of the old
grease looked like a normal grease so I did not use antistucking  grease
with 1000 C tripping point and a lot of Cu.
Best.
Petro.
