    Default Nagler 13 or Nagler 11???



    Hi,
    I have a dobson Z10 f/5 so I need good eyepieces. I´m searching a premium one in this range (low power is for GSO Superview 30mm). I don´t want the 12mm because is too heavy an more expensive too. I can´t choose what would be better for my scope to use it in deep sky, 11 or 13?? .........I have a Barlow Celestron Ultima too, so the winner nagler will be used as planetary eyepiece (6.5 or 5.5mm)
    Help me please or my mind will blow up!!!!

    Clear Skies! Jose

    With my Orion XT10i (10" f/4.7) scope my favorite eyepiece is my 11mm. But I didn't go Nagler, instead I went with the Explore Scientific 82° and paid about half the Nagler price. The ES 82° eyepieces are well corrected for fast scopes, and are really the best bang for the buck you can get in an eyepiece right now (while the sale continues.) The Naglers are slightly better so if nothing but the best will do go with them, but if you want 90% of the performance for less than 50% of the price, go with the ES 82°.

    Gotta ask you WHY you would want a HIGH POWER ..WIDE FIELD eyepiece...

    with any high powered eyepiece you are generally looking at a very small area of the sky (the moon Jupiter/Saturn or the core of a Globular cluster ect so why do you need (except to make tracking a little easier in a push it along Dob scope with no slow mo knobs ) to see a lot more back round area ????

    All of my medium and low powered eyepieces are wide angle (not even ultra wide angle) but all of my high powered eyepieces have no more then a 55-60 degree FOV and I sometimes will drop down to a narrow field Plossl eyepiece

    I sold my dob more then 10 years ago so the tracking exception may be warranted I just can not remember ever having any problems tracking at high powers..
    On your other question (when not using the barlow) Personally I'd go for the 13 mm (92x if I am correct ..180x is about perfect on planets on most nights but 220x (with the 11 mm and a barlow requires much better seeing in general

    (I am assuming the Z-10 is a 1200 mm scope) Of course you could break the bank and buy both...LOL

    Sorry after I posted this I realized I did not really read you post "close" enough to figure out you were not looking for a stand alone high powered eyepiece BUT intended to barlow the 11 or 13...for high power... My Bad !!!!

    Well, if you are viewing the moon a wide FOV would make sense, because you get good magnification and can fit more of the moon in your view. As far as other objects go I find it really nice to have a wider field just for the fact that I dont have a goto or push to, so i can use that wider field to help me find the faint fuzzies that im looking for without having to change EPs. Also maybe its just me, but I find averted vision is easy and enjoyable with wider fov eyepieces.

    As far as buying an expensive EP goes, I am biased on this, but I find the Explore Scientifics to be on par with the Naglers for the most part, and a huge cost saving.

    I,m from Spain. Here, the price difference between ES and Nagler is about 50 euros and if I buy the ES in USA I will have to pay ship and customs so the price is similar. By other hand, I prefer Nagler becouse I have a fast scope (F=5 1250/250) and brightness and sharpness is better. I prefer wide field cos is a dobson...and i want to have located the object in the eyepiece more time.
    13 mm are 92 x, right, but it will be enough for majority of globular clusters?: Encogiéndose de hombros:
