    Re the corrective treatment you gave the sextant, you mentioned "brushing, blowing and rinsing" to get it free of sand. I would assume that you lubricated the instrumet after rinsing, with fresh water, no doubt.

    Anyhow, what do you use for lubrication. I've seen reference to lubing the rack with a "light coat of petroleum jelly", otherwise known as Vaselene, then turning the micrometer so that the worm moves across the rack, picking up some lube in the process.

    In my copy of The Nautical Sextant, oil and oiling are mentioned in the index, but other than this, there seems little information on this subject therein, at least in-so-far as I can see.

    I have an Astra 11B, that has yet to "go to sea". Since I'm not likely to so do, it probably won't either. I do use it shooting on the beach, where I try to avoid really windy days, and brush and or wipe the instrument after use. Here in Pittsburgh, I sometimes do some shots along the river bank, no particular problems with salt spray or blowing sand there. So re lubing, what do you or anyone else who comes on the foregoing suggest?

    Thanks for your attention.
