My 1200 has not been used for about 2.5 months. : ^ (

When I went to take it out of its case today there was a light coating of

oil on the bottom of the RA housing. Is this normal?

Some of the light grease used on the internal bearings may have had a bit of

oil separation. Nothing to worry about. My mount has done this also from time

to time.

Speaking of oil.........

Roland I would imagine you might know the answer to this question. Can you

recommend what kind of light oil (WD40?) to use on a very squeeky and sticky

set of camera adaptor threads. They are very close to the coated corrector

lens of my Takahashi BRC telescope and I'm concerned about any outgassing

that might be harmful to the coatings. But these threads could use some help

if it's possible. Is there a light oil that's totally safe to use near

coated optics?

At my local astronomy shop they use "bees wax" on the threads to

eliminate the squeaking. It seems like that would be a good

alternative when there are optics nearby. I have not tried it myself

yet to confirm.

I would recommend wax also. Car wax makes things quite slippery and won't

outgas after it has dried. Oil has a tendency to creep. Silicon oil will

creep very long distances and can ruin optical coatings because it gets

underneath them and the coatings literally fall off.
