    For my 10 and 12 inch dobs I have EP racks mounted on the base. I typically start with my ES 82 18mm in the focuser. I have multiple 2" to 1.25" adapters and typically put my 14mm, 11mm, 8.8mm and sometimes the 6.7mm in their own adapters and put them in the racks. That way it is a simple method of swapping 2" EPs (through use of the adapters). I keep them in a specific order in the racks so I always know which EP is selected.

    In the 17.5 inch dob I don't have an EP rack on the scope, so I simply line them up on the observing table. I always deploy my 48" folding at all times since I put my case, atlas, notebook, two pairs of glasses and binoculars on there. Should conditions be particularly dewy and the EPs start to show condensation while in the rack or sitting on the table, then I lay them flat in the case (again in order) and loosely close the lid to protect them from dewing.

    I have also used JGs methodology of keeping EPs in coat pockets. Mainly done on nights when dewing/frosting is an issue.

    For a moment I thought you are advising to paint EP's front lens with red polish.

    I have used a black permanent marker (Sharpie) and written the eyepiece focal lengths on all the bolt cases in large numbers. I can usually read them in the dark once my eyes are dark adapted.

    If you're going to use nail polish, why not just put a glob or two on the side of the EP? You should be able to feel it.

    Maybe a felt dot or or a small self-adhesive rubber foot like on the bottom of a toaster?

    I usually keep the boxes open and put the eyepieces in the boxes and mark the size with a yellow fluorescent pen on the side. Works for me with a small red led flashlight. The problem I have is loosing the plastic covers for them when I need to put them away.
