The Baader #4 Ultra-range mount grease is a wide-stretched synthetic grease with constant viscosity across an extremely large temperature range of -50 to +60°C. It is especially su itable for use in the mirror sliding fittings of Schmidt-Cassegrain telescopes as the grease does not produce any out-gassing, does not react to vapor-pressure, does not harden over time - and does not decompose into a solid and a liquid part over time.
