    Default Hyperion vs E-Lux



    This is not a fair comparison considering a 4 element design vs an eight. However, the Baader Hyperion 24mm (68deg AFOV) was far superior to the Celestron 25mm E-Lux Plossl (56deg AFOV).

    1. Celestron wins at about 1/3 the price.

    Visual comparisons are based on use in my 1250mm focal length Nexstar 5se, the magnifications are virtually equal.

    2. True field of view goes to the Hyperion.
    3. Image brightness, IMHO, was much better in the Hyperion.
    4. Image clarity at the center of the FOV was (IMHO) slightly better in the Hyperion.
    5. Image distortion was minimal, in the Hyperion, near the edge of the FOV, and noticeably worse at the edge of the FOV in the Celestron, although not intolerable.
    6. The area of image distortion is noticeably smaller in the Hyperion.
    7. Both eyepieces seemed equally comfortable through which to view. In other words, any difference in eye relief (no glasses) was not great enough to warrant researching the data. Also, the size of the lens nearest the eye may differ, but each was adequately large.

    The above was my attempt to be objective. Now for my real emotion driven evaluation.

    The Hyperion simply blew away the E-Lux and is worth extra cost! Its hard to put one's finger on it, but that is the impression here.

    Now, to look through a Nagler!

    Best Wishes All!!!!

    The Elux is the bottom of the line EP that Celestron ships with many of their scopes. I think they have been discontinued but if you find them at a dealer they are cheap.
