    Default 11x70s or 15x70s



    I've been into astronomy for several years (a member here for a few) so I'm not a complete newbie. I have several scopes and the collection is still growing. I've moderately gotten into AP and that interest also is still growing. But through it all I've had a set of 10x50s. At first they were just a help for finding objects and quick glances, just a tool like my reticle eyepiece used for a few minutes and then put away. I didn't really want to invest more money or time into their use. Then I saw in a post from Lowjiber where he made a monopod from an old mop handle. What a coincidence! In my trash outside was an old mop and I thought "Why not?" so I gave it a try and immediately started using the 10x50s much, much more. But that just lit the fire. Now I've got a parallel mount and been really using the 10x50s at home and at the dark site. Last trip to the dark site didn't even include the use of a scope, took one along but it didn't even get set up. I like to do a lot of research and am slow and methodical to my purchases, so am in that refinement process now. I've asked JG our local expert and he has put me on to the BA8 10.5x70s and that is most likely a purchase for the future. However like scopes, I will most likely have more than just one (set) and don't really have the funds for the 10.5x70s right now and have decided on some that are a little more economical. I have decided on Oberwerk LW 11x70s or 15x70s. Both sets are same price and same weight with the obvious differences in magnification, exit pupil, and field of view. Considering these two sets, what do you guys think?

    I really like what Oberwerk has to offer, and they have excellent customer service and well packaged fast shipping. If you've got the parallelogram mount, heck, I'd go for the 15x70's. That would be a nice jump over your 10x50's in my opinion.

    I love binoculars. They're like Doritos, and you can't have just one. I've got five now. My next bino purchase (some day) will be up in the 20x80 range or larger.

    Based on the exit pupil alone, I would go for the 15X70s. The views will be outstanding, and all of the light will actually get to your retinas. The 11X70s produce an exit pupil of about 6.4mm, which is greater than the maximum pupil size of many observers--especially older ones.

    I can't compare them because never tried 11x70. But my 15x70 Celestron are awesome and they have given me a lot of nice views!!!

    I would go 15x70. I have Orion 15x70 and 10x50 binos. Both are good, but I prefer the 15x70s for astronomy.

    Hi Ozman. For many years I only had a great pair of 7x35 binoculars. More recently I have now acquired the Celestron 15x70 binoculars. In both cases, they give me a roughly 5mm exit pupil. Some day, like Bryan, I may go wild and get a 20x80 or 20x100 pair. In any case, these are always handy for a nice sky scan, or for terrestrial use. I hope this helps Ozman, and the best of regards.

    Hello Ozman,

    the 11x70 and the 15x70 from Oberwerk are practically the same, just with different eyepieces.
    When you want to choose just one, than go for the 15x70, more magnification reveals more of those faint fuzzies.

    Having the 15x70, the next step would be the 25x100.

    Best,
