    Default Stellarvue 82º opinions



    Hi everyone,
    I currently have a bit of weakness on the high magnification end of my lineup. I am really happy with my wide(-ish) end (ES 82º 24mm) and medium to medium-high mag (Meade UWA 14mm and ES 11mm), but the quality of my other EPs is not really the same (the Olivon 70º series). There is some coloration and lack of contrast, and I find myself wishing for a better option there. I was thinking of the Stellarvue 7mm - this one: https://www.highpointscientific.com/...1-25inch-euwa7
    It would give me a slightly over 1mm exit pupil (f/6 dobsonian), and a magnification that is manageable while pulling out some double separations and details - significantly higher than this ~170x factor hits big seeing limitations for where I usually observe. And I like the large FOVs - I know opinions vary on this point, but I really enjoy the spread-out, immersive field.
    Is this a good choice for a reflector design? Any other suggestions in this range (I want to keep the cost at about this level maximum if I can).
    I know a Barlow is another obvious choice, but I kind of feel that a "native" piece in the desired focal length is a more straightforward approach - happy to be convinced otherwise though.
    Thank you!

    I have no experience with that specific EP and it may be exactly what you want, but have you considered the ES 6.7mm 82? You can already attest to the fact that the ES EPs you already have work well for you, me too. I use the 6.7mm in my 8 f6 Dob to very good effect, along with the entire line (except the 4.7mm) of 82s and most of the 68s as well.

    There's always the shockingly affordable Meade UWA's too Doc. The 8.8mm works well for me, the 5.5mm I hear alot of people say they think its the best in the line, but to be honest I just don't get much use out of it. I'm not much of a fan of high power viewing through the dob, never have been. I just keep it in the event I really want to drill down on something, and it works well in the short frac also.

    Thank you both. I have to confess, the 7mm length was a big attraction, since it would sit in a bit of a sweet spot and let me use it as THE high mag piece. As Don says, I don't find myself using high mag too often, but when I do I'd like something that matches the quality I put together at the wider end. Ozman, that 6.7 is definitely the main alternative, and you're right, I'm happy with the quality of these pieces - I just have the small gripe about the rubber ring not being too insulating from ambient light. Maybe I need to get over that...

    You know I don't think I own a single EP with a standard eyecup I can say that about* - they're all too short. That's where I think the Meade has a leg up, at least for me, the twist-ups I can draw all the way out and it's the right height, I stick it right in my eye socket and it fits beautifully.

    Little things.




    *in retrospect, the GSO superview wasn't too bad.

    Yes, I really like that twist design and the fit of the Meade! Another reason I’m looking at these possible alternatives to the ES EPs.

    If you already have and like ES82 EPs the safe choice would be to go with ES82 6.7mm. There is only 4.5% difference from 7mm you aiming for. From my experience you need ~10% to see the difference by eye. ES82 line has been tested by many, and works well in DOBs.

    The chances Stellarvue would place its name on a mediocre EP and sell it for $144 are pretty slim, but we don't know whether it was designed to work with fast newts like ES82.

    Me two! I prefer Meade UWA design over ES82. You could post on CN and AM and with some luck find older Meade UWA 6.7mm

    I found my Meade 18mm this way.

    Yep. As far as I know the only 82 deg 18mm EP in existence in 1.25" format.
