    Default 2" eyepiece



    I have a 10" Orion xt10 that came with a 2" holder. All my eyepieces are 1.25. Would like to upgrade to 2" but don't know where to start. I was thinking of starting with maybe one in the 25-35mm range. Is that reasonable?

    The ONE EP I would NOT be without!!!! It is the most used EP by FAR in almost all my scopes (some only have a 1.25" focuser or it would be ALL).

    Quite reasonable.

    Just keep exit pupil in mind when considering. Were I you, I'd try to keep the eyepiece focal length under 30mm with the XT10, otherwise, you risk the shadow of the secondary mirror becoming visible in the view and getting annoying, especially with brighter objects (Moon, Jupiter, etc.).

    I quite enjoy the Explore Scientific 82° eyepieces with my AD12 dob. The 2" 18mm from that series is a wonderful eyepiece in my dob. I seldom go with a longer fl eyepiece that that one, though sometimes my 24mm will get a nod. The 18mm and the 11mm from that same series make for a fine hunter/killer team for galaxy hunting for me.

    Quick replies! I liked the price on the 18mm compared to some I've seen. Looks like I need to do some exit pupil research now

    Hi Ron. I enjoy using 2" eyepieces for wide field DSO viewing with my 6" refracter (f/5) and 12" Dob (f/4.9). And my crown jewel eyepiece is the 2" 18mm Explore Scientific 82°. I can usually start and finish an observing session with just this one eyepiece. I hope this helps Ron, and the best of wishes on your 2" eyepiece purchase.

    18mm it is. Now to just order one. I'm impressed with the recommendations for the 18mm. Definitely comes with some good endorsements!
