    Default Eye pieces?



    I am getting the Zhumell z10. It comes with a 30mm and 9mm eyepieces. What other eyepieces should I get in order to get the most out this telescope? Thanks.

    So many to choose from. Do you have a budget? I can tell you that investing in a good Barlow lens is certainly a thing to consider. It will give you 4 different range eyepieces with what you have now. I'd get at least a 2X. Celestron X-cel series have a good reputation and are quite affordable. Personally I'd get either a TeleVue powermate or a Baader.

    Thanks. I was thinking of definitely getting a Barlow and maybe another lens somewhere in between the 9mm and 30mm. As far as a budget, probably around $100-$150.

    Don't be in a hurry trying to update your eyepieces. Give yourself a proper time to know well your scope, the objects you love to see better and then you can decide what "type of glass" you will need/want.

    For now I'd like to advice you to read this article about eyepiece basics: Tele Vue Optics: Choosing Eyepieces (Basic).

    Good luck with your scope!!!

    First thing I would suggest is to start using the scope with the EPs that come with it for a while. If possible, get with a local astronomy club to experience different EPs with different scopes. After you have some experience with your EPs, you'll have some other questions about EPs that you haven't thought of yet, and answers will have more meaning to you as well. Do lots of research, ask lots of questions, and weigh that with some of your own experience before you start to upgrade your equipment.

    I second that idea. The 30mm that comes with the Z10 isn't a bad eyepiece. The 9mm is a Plossl so it requires a lot of guiding with only a 50 degree AFOV. So a 2x Barlow will give you effective focal lengths of 30, 15, 9, and 4.5mm which spans the useful fls for this scope. I use a Tele Vue 2x Power Mate but they are pricey. The X-cel isn't a bad choice. Once that is done I'd consider a wider field ep in a shorter focal length. Maybe a Panoptic 19mm if the main interest is DSOs or the Delos 17.3mm if planets are the thing. Then the barlow gives 10mm or 8.7mm. The 9mm that comes with the D10 is the first thing to replace.

    I have a Z12 and love the combination of Panoptics and Delos with it.

    Those guys are right about getting some time in with the scope first.

    I started with the same 30mm and 9mm that you are getting. I did add a barlow though.

    Anyway, I managed the whole Messier catalog with my 30mm. At that point (about 4 months of use), I had a good feel for how and what I wanted to observe, and had spent the time learning how others were observing similar objects with similar scopes. By the time I was ready to make a purchase, I had a good feel for the direction I wanted to go.

    With the experience and learning to back up my decision, I feel I made an excellent first choice of an eyepiece, and also with subsequent purchases.

    Better to go slow and purchase wisely than to buy fast and regret it.

    But, all that said, stand by for some good options to be heading your way via this thread. Just bear in mind, eyepieces can be a very personal thing. I can tout my ES 82 series, but I have a friend with a similar scope who can't tolerate them. Everyone's eyes are different.

    Good advice. He should (when ready) take a look through an 82 degree AFOV from ES or TV to get a feel for it. Try before buy is always good.

    I'm one of those who can't stand the 82 degree format. I'm perfectly happy with 70 degree AFOV and when I want to go large I'd rather go for the 100 degree formats. So it's not that 82 deg is too big for me.... there's just something about them I can't take.

    But I fully respect your admiration of the 82 degree format. There is nothing wrong with that. It's a valid lifestyle choice.

    OK the 30mm is a 2" eyepiece and the 9mm is a 1.25" eyepiece. I agree with the folks that say use the eyepieces you have so you know what you like and don't like about them. But a barlow.... is pretty essential and doubles the number of eyepieces you have.

    The thing is that you want to be able to barlow the 2" 30mm eyepiece and the 9mm also. So you need a barlow that can work with both 2" and 1.25" formats. That limits options considerably.

    The Tele Vue Powermate 2x will do that but it is outside your budget range at $265. The Celestron X-Cel is for 1.25" only so it will only work with your 9mm eyepiece.

    I have 2 specific recommendations that are close to your budget.

    One is a little more of a stretch $-wise
    Tele Vue 2.0x 2" Big Barlow Lens with Compression Ring - BWC-2211 - Barlow Lenses - Telescope Accessories

    It has a 1.25" adapter so it will work with both your eyepieces.

    The other is still a stretch but a much smaller one.
    Explore Scientific 2" 2x Focal Extender - FE02-020 - Barlow Lenses - Telescope Accessories

    I use the TV Big Barlow and the Powermate and both are good. The more pricey Powermate has some nice features that you probably wouldn't care about at this point. I have no experience with the ES 2x 2" barlow. Maybe bladekeeper can weigh in? It should be good.

    A 2x Barlow is a good idea, I actually have three (1.25" 2xBarlow, 1.25" 3x Telextender, and 2" 2x Barlow). The HighPoint Scientific 2x 2" ED Barlow works well and is a good deal. It has the 1.25" adapter to fit 1.25" EPs. It also allows you to remove the lower element to use as a 1.6x Barlow for your 2" EPs as well, giving you double duty for your larger EPs. It will turn your 30mm EP into a 15mm and 18.75mm EP. However, as your EP collection grows, your use of the Barlow will decrease because of it's redundancies.
