    Default EP Relief



    How important is ep relief? I'm looking at getting a Nagler ep and eye relief varies from 12 mm to 19 mm. I wear glasses but many times remove them to observe thru ep since mine are low price that came with the scope 45 yrs ago. I'm also considering getting a 12" dob instead of an 8" an all ep's I buy will hopefully be used in both scopes.

    If you want to keep your glasses on, then you'll need the longer eye relief. If you take them off to observe it's less important.

    Personally, I like the longer eye relief of the type 4 Naglers - I usually take my glasses off to observe, but although I find the shorter eye relief of my Type 6 2.5
    Mm usable, the longer eye relief of my Type 4 12 and 17mm eyepieces feels much more comfortable.

    But eyepiece choice tends to be a personal thing, so if possible, the best thing is to see if you can have a look through them before buying.

    Unless you have some issues with astigmatism, you can remove your glasses while observing and simply focus for correction. (I take mine off, and on, and off...) The longer eye relief is more comfortable for me also, but find that 10-13mm is really a non issue.

    I have a couple of EP's with very tight relief where I can feel my lashes sweeping the glass when I blink. These you'll likely need to clean more often.
    Or I guess you could consult your favorite cosmetologist and have an eyelash trimming. You may look like a turtle, but your EP's will be happier.

    I wear TRI focals and I never wear them when looking through any of my scopes and lenses. Mind you, they come right back on if I have to turn away to look at Stellarium on my laptop, even if it's for a short moment......
