    Default Eye guard for 2" long eye relief EP?



    On Saturday I had a chance to use my latest acquisition - Russell Optics 56mm Super Plossl. The EP seems to work as intended. It is sharp in my 8" SCT, and I like the built quality, compact size and light weight.

    It has a long eye relief (as expected). Your eye need to float ~2 cm away from the lens top to see the image. Eye position is not that hard to find and hold. What I like to have though is an extended rubber eye guard to block the stray light. The EP comes with top cap, but no eye guard.

    So, does anyone knows where I can get a rubber eye guard to fit on top of the EP? It has ~5 cm diameter. At the very least I will look for a piece of rubber tubing, but would like to have a more refined solution.

    Agena carries a few of these, not sure if they have a size that's exactly correct, but you know what they say: Beat it to fit...paint it to match!
