    Default Eyepieces?



    I'm sure the forum gets lots of questions on eyepieces so sorry for the repetitiveness.

    I have super 10mm and super 25mm EPs that came with my telescope and I think there of good quality but what do I know? I haven't really had the chance to really test them yet and being a beginner to the telescope business, I can't tell a good EP from a bad one.

    I'm wondering if there are any eyepieces that are a must have and what brands are reliable? I would like to buy an eyepiece and filter set but I'm cautious about them as I think they'll be all the cheap, low quality EP and filters.

    You've probably got Plossl eyepieces - which should work pretty well with your telescope.

    I'd probably not buy a kit. Test out what you've got and consider buying a Barlow, one or two more eyepieces and a Moon filter.

    You might also consider getting a zoom eyepiece because the convenience you get is just awesome.

    The only filter you should buy is a moon filter; I do NOT recommend that you buy any colored filters.

    Wait with buying eyepieces until you know what you need and why. The eyepieces you have will get you started. Once you know how they behave on different objects, you will know if you need more magnification, a wider field of view, or something between what you have now.

    I've already got a moon filter and a barlow but haven't had the chance to use them yet. What's a zoom eyepiece?

    A zoom eyepiece typically will supply focal lengths of 8-24mm in one package. The Baader Hyperion is likely the best and is pretty parfocal - meaning that when you change the focal length (magnification) you will need to make only minimal adjustments in your focus.

    The zooms mean you don't have to fumble in the dark to change eyepieces and you don't have to constantly make big focus changes.

    But there is usually a little loss in quality toward the edge of the field of view and the field of view tends to be less than a regular eyepiece being used at a similar focal length.

    I agree with waiting and using what you have. The stock 10mm and 25mm are of decent quality, and should last until you can figure out what you need.

    Best to use the eye pieces that you have and get familiar with what they do before you decided to sink more money into new gear until you know what you really want to view..

    I am a newbie here myself but come from a photography background so I know a teeny tiny about lenses, and a lot about buying things I should have never bought, heh.

    First thing I would do it get in touch with a local astronomy club and see about going out with them to a star party. Check out other people's scopes, see if they will allow you to use their EPs to see what focal lengths you might want, and then start researching specific models. Much like camera lenses every different model from every different manufacturer has its pros and cons so read some reviews.

    Be prepared for one thing I was not, size. A long time ago I started with a cheap set of EPs, I am starting again now with Orion Stratus EPs. If I threw my old Celestron 25mm at a car windshield I could probably crack the windshield, if I did that with my 24mm Stratus it would probably go through the windshield and kill someone on the other side, it is HUGE and HEAVY.
