Hi Adrian, I had to replace the 30 year old grease from my Unitron mount.
I spoke to Don Whiteman at Bintel and he recommended Superlube.
You only need a very small amount, it can handle temps from -40c to 100c, so it's perfect for the varying temps that astronomy brings. It won't run or freeze up.
I can't remember the supplier here in Sydney, but I'm sure a Google check will find it. Cheers, John.
