I was looking for a lens cap for a Zenithstar 70 ED, and found that the lid of a Haigh's Chocolates tin (400gm 'Cinema Mixture'), is a neat sliding fit. The metal lid has an inner plastic sleeve, as pictured, so there is little chance of scratching the telescope. The ID is 95mm, and it may work for similar models.
Its a grab and go telescope, so just bung it in the backpack and jog to the preferred dark sky sight, potential diabetes problem solved! (Of you could just use the lid and bin the chocolates ... as if!).
Diabetes?
