FWIW, I used graphite powered and lubriplate grease some 15 years ago on our 8" LX200. The oil has never separated, and the image ship was improved. I forget, but seems to me I had a large percentage of graphite powder vs grease.

Dow Corning High Vacuum Grease .

Unlike petroleum or synthetic grease, this product will not out gas.

A little bit goes a LONG way....

I just bought a tube on eBay for $18. It's a heavy duty grease for sure. I will be regreasing my 14" LX200 OTA this summer.

Don't use vacuum grease. This grease is designed for high vacuum glassware that chemists and such use - not for lubrication of moving parts. Otherwise SCT baffle lubrication is an incredibly undemanding application. Meade has seriously screwed up by using their sticky gunk and Celestron has remarkably gone one step further in using grease that can out-gass and even drip. I use Mobil 1. It's probably the most tested grease in history and is a good Group III grease. The boutique greases like Superlube are ok but not any better. So really, buy a tub of the pink stuff Celestron recommended and be done.

I would second the recommendation not to use the vacuum grease. I bought a tube and when I saw the consistency said no way. It is a sealer, not a lube.
