Do you know or have you ever asked that the gas mixture used to fill the S & B FT?
I've heard from different mixtures of nitrogen gas, which have the character to have larger molecules, and with fewer losses and a longer lasting filling the telescope. This mixture, however, seems to be more sensitive to temperature changes
