    Default ES vs. Zhumell eyepieces



    Hi, I'm considering adding a 6.7 or 8.8 80º ES eyepiece to my collection. While the larger field of view alone is a valid reason to consider purchasing one, I'm wondering if I would see a noticeable improvement in viewing Saturn or Jupiter? As of now the Zhumell 14.5 Planatary allows me to see cloud bands on Jupiter pretty well and I could even see the GRS with the Barlowed 9 that came with the scope. I'm just looking for a bit more fine detail. Perhaps I'm viewing the most detail I can get but I wanted to check with more experienced users.

    Thanks,
    Patrick

    You'll get better eye relief out of the Zhumell, but the ES will be "cleaner" and likely brighter. I have a Z 5mm, and I haven't really compared it to my ES 4.7mm. Those don't get a lot of focuser time for me unless the seeing conditions are good, and that hasn't been very often lately.

    That's just my take on things. Generally speaking, when it comes to eyepieces, you often get what you pay for, though the Zhumell's are quite effective for the cost, well, at least the 5mm is. I have no experience on other focal lengths.

    I tried a Zhumell zoom the other night on Jupiter and it was excellent. I'm starting to like their eyepieces in general.

    Thanks Bryan! Cleaner and brighter sound really good! Those reasons also sound valid for considering a lower power one for those DSOs.

    I get better contrast out of my ES's than I do with my Apertura 30mm (same as Zhumell I believe) which gives a better view in my opinion. Plus I can really see a good amount of spherical aberration in the Apertura but that could just be due to the focal length.

    The 30mm that comes stock with the Apertura and Zhumell scopes is a much different animal than the Zhumell Z series. The 30mm is an Erfle design and it does display some coma around the edges of the FOV in a faster scope like these dobs. The Z series are the same as the Orion Edge-on Planetaries, only the Orion's are much more pricy. These are also the same EP's as the Long Perng "Long Eye Relief" offerings.

    The Z series (and clones) offer better correction for faster scopes over the Erfle designs. So to do the ES's (and better).

    As already noted, the ES will offer a much wider AFOV over the Z's.

    It is so happened that I have tested barlowed Zhumell 14.5mm Planetary side by side with ES 82 6.7mm in my C8 on Jupiter. ES 82 produced less light scatter, sharper focus, better colors and overall more refined view. View through Zhumell was good, but ES took it to the next level, with more fine details in Jupiter cloud belts.

    Thank you! This is exactly what I was hoping and it sounds like I'll be happy upgrading to the ES 82 6.7.

    For their price (under $50) the Zhumell Z series are definitely solid performers and a good choice for anyone on a budget. That said, go for the ES 6.7mm! Mine is great on planets and globs in my 4.5" Newt and noticeably better than my budget EPs. With a manual Dob you'll appreciate that wider fov also.
