    Default Eyepiece Help?



    I currently own a few Orion Sirius Plossl eyepieces, and would like to upgrade them to the best possible eyepieces available that range from $80-150. Please don't hijack my forum with comments about why the Stratus is inferior to the Hyperion or vice-versa when they are virtually the same eyepiece with different names. I would like first hand account not information based on a theory about a manufacturer. I hope these statements don't seem too agressive, but I don't want any unreliable information, please. I would like to state I have been looking at the Stratus/Hyperion and have considered them as an option, but I would like other opinions based on my price range. They seem like one of the better all-around choices for my price range, 68 degree FOV and 20 degree eye relief.

    In my opinion, the best eyepiece in that price range at 68* is the Explore Scientific 68* or 82* series. Some of them may be on the upper end of your price range but they are exquisite eyepieces. They are waterproof and have great contrast and brightness.

    What kind of scope do you have and what focal lengths are you looking for?
    15 inch Obsession
    Low Power: ES 28mm ~60x @1.1° : Televue Delos 17.3mm ~100x @.72°
    Medium Power: ES 14mm ~122x @.82° : Televue Delos 10mm ~170x @.42°
    High Power: Televue Delos 6mm ~285x @.25° : ES 4.7mm ~365x @.22°

    I have been considering the Explore Scientific 82*, but right now my biggest turn off about them is that they aren't all 1.25". I don't quite understand what the advantage of waterproof is? I don't plan on swimming with the eyepieces, viewing in the rain, or doing any other water sports with my EPs. I would think that all EPs would be alright with a little sprinkling, but maybe I am naive. Do they have good contrast and brightness to the edge?

    They do have good brightness and contrast to the edge. I didnt plan on viewing in the rain, but conditions can change rapidly somtimes and I have had to run for cover with the eyepiece out in the rain. But aside from rain, they dont allow moisture to form on the inside, which in a normal eyepiece can form fungus/mold.

    I have an Orion Mak-Cass 127mm(5"). I really like it. I'm hoping to bump up to a Mak-Cass 180mm(7.1") sometime either end of this year or next year.

    The ES82 should perform well for you, and like you, I was weary of purchasing one myself considering the lowest power I could get for my 1.25'' was 14mm but I went ahead and bit the bullet.

    I do enjoy the EP significantly, yes, but it's not quite the "night and day" difference I was expecting. This could attributed to the fact that I have an F/5 Newt and currently do not own a coma corrector/field flattener, and they inherently suffer from coma.

    Just my experiences

    I have converted all of my EPs to 2" barrels and put parfocal rings on them.

    I don't quite understand what the advantage of waterproof is? I don't plan on swimming with the eyepieces, viewing in the rain, or doing any other water sports with my EPs. I would think that all EPs would be alright with a little sprinkling, but maybe I am naive.
    I, personally, have never had an EP get moisture inside. However I live in the desert SW. I read, just yesterday, of a person in the more moisture challenged SE who had several EP that would dew up from the inside unless he wraps a heat blanket around them.

    Do they have good contrast and brightness to the edge?
    The ES line(s) are very good copies of the Televue lines (Naglers and Ethos) at very nice prices.
