    Default Are 2" Eyepieces Worth the Money?



    Hello. I'm new to astronomy and just received my Celestron CPC 800 GPS. I also have the 1.25" eyepiece set for it, and the two lowest power eyepieces seem to work best for me.

    I'm wondering whether it's worth the investment to go for 2" eyepieces. I'm also wondering whether individual eyepieces would be better than one of the telescoping eyepieces (my terminology might not be right on that).

    Any advice from all you pros?

    Jerry-

    To me it is worth going to a 2" system myself. You can do it economically for around $150-$200 with an EP.

    I like GSO branded accessories. They are well made and quality. Their 2" diagonal has a quartz version I believe that may be a 1/12 wave.

    The price is roughly $125 then a used 2" EP like a Baader works well in the CPC lineup. In fact I have a CPC800 as well. Great scopes!

    For some threads on 2 inch vs 1.25 inch eyepieces:

    1.25" vs 2"

    1.25" or 2"?

    I have some 2" and some 1.25" eyepieces, and they are pretty much the same to be honest by the same company. Only difference is the 2" put strain on my mount and the focuser... lol

    A 2" barlow with a 2" eyepiece is quite heavy!

    I love using 2" lenses, especially the Q70 26mm. Absolutely an entirely different view from using a 1.25" from my experience, but everyone sees things in their own way.

    With my Xt8's stable mounting system I can set the scope completely horizontally with a GSO 2x Barlow and a 2" 32mm lens loaded up, and its absolutely stable with no dipping at all.

    My collection consists of both 2" and 1.25" lenses for diffferent viewing needs. "Both" is the way to go imo, if you have a focuser that can handle it.

    My Meade 2"QX 36mm is very nice. Some folks complain about vignetting around the perimeter of the field of view, but it is hardly noticable to me. Big views. Wide views.

    I love my Meade 28mm Series 5000 SWA. Expensive and heavy, but it's a keeper.

    2 inch eyepieces are great, but let the buyer beware. There are cheap 2 inch eyepieces that have poor optics. You get what you pay for.

    My last scope was the size smaller than 1.25". (less than an inch I believe)
    When I got this new scope...it had a 2'' eyepiece included.

    When I looked through that eyepiece the first time...it was as big as a dog dish!
    (now these 1.25" models look big to me!)
