    Default Eye relief



    Tonight I was viewing the moon and I just couldn't keep my eye in the sweet spot. Anyone else have this problem? What if anything can I do to eleaveate the problem? I was standing while viewing.

    sounds like you are using Plossls and that was the reason i bought better eyepieces, mine would black out if i wasnt in this certain viewing angle.

    Not sure...what EP were you using? Whats the fov and eye relief of the EP? Some EP's are just harder to view with..thats one reason I dont use plossl that much even though I have some.

    I have a 32mm Televue plossl and its eye relief is so long it can be hard to view in the sweet spot as my eye is up off the eyecup even. I have luck just using a finger or two around my eyebrow to space my eye properly.

    What eyepiece/barlow combo were you using? From your avatar pic it looks like you have a NexStar 5SE, which is an f/10. If you were using an eyepiece shorter than 10mm, I imagine it could be difficult to stay on the sweet spot, as the exit pupil would be smaller than 1mm.

    Get an adjustable height viewing stool or chair. When you're body can relax it's much easier to keep your eye at the eyepiece for longer periods and see more detail.

    Some better eyepieces will help, but I think my first investment would be a decent stool or chair (adjustable height is important -- otherwise it'll be at the wrong height more often than not and that sort of defeats the whole point of having it.)

    just thought i would answer my own question, kinda. i purchased a celestron s-cel lx in 25mm for 60. today and so far during daylight its awesome. compared to my 25mm plossl well there is no comparison. this new ep is bright, clear and has a great fov. i have no probs with the sweet spot this ep is a joy to look through. im really wanting to pop for another now. how very true a so-so scope can shine with a good ep.
