The grease used should have two qualities - it should not liquify at higher temperatures, and it should not emit vapours which might form a coating on the etalon surfaces.
If your grease is not labelled I will send an enquiry to Bintel (where I bought the scope), or Lunt.
cheers Phil
Hi Phil,
I did receive a very small amount of grease in a double sealed bag. It appears clear but with no identification sorry.
I ended up using both 34mm orings. But haven't used yet as been too busy over Xmas.
Would appreciate knowing what you find out.
Been trying find an Oz supplier of the Largermeister grease mentioned in Merlins post.
Regards
Peter
