    Default Zhumell Eyepiece kit



    Last year I built my first 10" f/5.6 Dob. I purchased one of the Zhumell 1.25" Eyepiece kits with filters to get started with (was on sale at the time). I haven't gotten a lot of viewing time but I don't feel the eyepieces are giving me the quality of imaging that I want. From others experience with these eyepieces, how much quality SHOULD I expect out of this set?

    I was trying to view Mars the other night, and it was really bright in the eyepiece and I could not get it to focus to a disk like I can with Jupiter. I can see Jupiter's bands ok with the Zhumell's and Saturn is clear when I can view it, but Mar's, I can't really enjoy viewing it.

    I am in the process of purchasing some better eyepieces, but I can't decide what I want. I have read good things about the GSO brand and am wondering if the GSO's would be that much of an improvement over the Zhumell's. I am also looking at Meades, but if I can afford it, I may go with Baader Hyperion eyepieces.

    My real question here is, are the Zhumell's lower quality than the GSO's and such?

    One other question, my main interest are the planets and DSO's, so Would a 2" have any benefit over 1.25" eyepieces?

    Thanks for any info. Reading through these threads for all the info is getting a little overwhelming for me right now.

    This is more of a problem related to viewing mars. Mars can be tricky to get a good view of, would better eyepieces help? Probably a little, but if you are getting good views of the other planets than Im assuming its not just your eyepieces.

    Ace, it's good to see that you're back...

    I'm assuming that you've got the set of plossls that they sell on Telescopes.com. I got the same set free with a recent scope purchase. The EPs work fine on the f/13 mak-cas I recently bought.

    At f/5.6, though, your scope is in the fast range, and from what I've read (not through personal experience), faster scopes are not very forgiving when it comes to using less expensive plossl eyepieces. Unfortunately, you may need to upgrade your EPs to keep up with your scope.

    Don't go buying anything, though, until somebody with personal experience comes along with advice/recommendations.

    Good luck.
    Mike

    I took a peek at Mars a few nights ago, and it was less than impressive. Even though some folks have been taking pretty good pics lately, for me it was still low on the horizon and not much more than a faded orange disc.

    Yep, the view will get better when it gets high in the sky.

    the kits that are available are not high end
    as you know,but neither are they junk.
    gso ep's are,on the whole good.better than their price
    tag suggests for sure.
    just a heads up,they supply meade with their optics aswell
    as others,who simply rebrand them,and hike the price up.
    so why pay more money for the same thing?
    a nice line of gso's are the superviews,if like me,you are on
    a budget and can't go $200 plus for an ep.
    i am more than pleased with the quality of views that my gso's
    give my eyes.
    clear skies,

    are you talking about those caps you put on the end of the scope that has 2-3 holes to cut down on the light? If so, I have one, but never thought of that. I have only used it for observing the moon.

    I will probably still buy some better grade EP's to add to my set. The Zhumell's seem to do alright sometimes, just depends on what I am looking for. I figure some better quality ep's may help improve my viewing. I really just need to get out more!

    As far as Mars, it just really seemed bright compared to Jupiter and Saturn. Thanks for the tips!

    Never really been gone, I check in here almost every night, but tend to read more than anything. Yeah, I have the Telescopes.com kit. I got it for a pretty decent price compared to regular price which is why I grabbed them. They have been good so far until I tried to view Mars. I have been trying to learn all I can about ep's.

    They are decent quality eyepieces and should give you fine viewing. Mars puts the best eyepieces to the test and the scopes they are on. Many variables affect viewing quality, and eyepieces are only one of them.
