    Default "BA8" 10x50's any good? Very little material on them



    Hi there !
    So I have been looking for a good, high quality "grab N Stab" (hehe) 10x50's suitable for milky way sweeping and the brighter clusters.

    It is my understanding that the BA8 models, branded as Orion, Oberwerk etc are supposed to be as good as it gets for 300$.

    But, most people just "assume" they are good because of the famous 15x70's from the same series.

    I'd like to know from people who own them, how sharp is the field ? Is it usable to 6.5 degrees or is it "fake" and only the middle is nice...
    How do they compare to other binoculars you have at this magnification range ?
    I did run several searches and found a couple very general testimonies, but figured it couldn't hurt to have another thread.


    Thank you very much !

    Not complaining for the lack of response, but may I suggest the managers to cancel the " viewing limit " for non registered users since it is pretty clear it kills the activity of the website.
    Most users are lurkers before signing up.

    Take my tip and you will grow.

    Hello and welcome to the forum!

    May I suggest you introduce yourself on the "Welcomes" forum. Tell us a bit about your interests and the like, and give us a chance to say "Howdy". We really are a friendly bunch.

    The lack of response you reference has two likely reasons. The Binoculars Forum is a little obscure/seldom visited and your question would do better tucked in with your introduction in the Welcomes Forum. May I suggest a title like, "Hello and a Bino's Question"

    Second, the subject of your thread probably didn't catch the "eye" of anyone who had the answers you sought.

    Here's an old thread you may have missed:

    Thanks for joining us!

    Hi,
    I normally check the bino forum regularly, and I hadn't seen this one before, so sorry about the lack of responses. It is very unusual.
    I haven't viewed through the Orion BA8's, but I have looked through the Williams ones, and I believe they are identical, except for their colour.
    They give very nice, bright images. Like almost any binos there is a sweet spot in the centre, and these ones have sharp stars for 70-80% of the field, starting to develop "seagulls" beyond that. This is better than a lot of binos I have used. Overall the full field is useable because generally you don't notice this amount of image drop off as we tend to concentrate on the centre anyway.
    They have good control of CA in the centre, with some lateral colour as you approach the edges, but again this is normal for almost any binos, including the high end ones such as Zeiss and Leica.
    I suspect the BA8's would give any roof prism binos under $500 a run for their money, and if you want 10x50 porro's that are superior to these you might need to check out the Fujinons.

    If you haven't found it already, there are some good comparisons here:

    All the best,

    Dean

    I've got a pair and they are fine although the collimation is just a little off. It may be within spec; I haven't had time to check. But no eye strain. They are a little heavy and the objective lens caps are a joke. They will not stay on. Would I buy them again? I can't really answer because I need 74mm i.p.d. (most stop at 72mm) and prefer individual focus over center focus and these fill both of those. If I found a pair of 8x or even 7x with 74mm i.p.d. and individual focus, I'd probably have gone for them as I find the slightly lower power easier to hold steady. They do appear well made.

    Also considering these, or the Pentax 10x50 to supplement my Celestron 15x70 that won't stay in collimation.
    After reading several forum posts, it seems that the main (only?) advantage of these over the Pentax would be the 6.5deg FOV, for 50% extra weight.
    Neither is available locally to me.

    My Pentax 10x50's are my favorite bino, and the ones I use the most. These are with me every observing session. The FOV is plenty wide enough and offers a great expanse of the sky, bright views, and sharp stars. These are indeed the brightest of all of mine. Great build quality and a fine product. The lens caps aren't the best, but the are serviceable.

    Thanks very much Bob ! I shall open a welcome thread on the forum for sure
    Dean no worries I wasn't complaining at all ! But I did find a lot of useful information here through google so I figured I would ask one myself
    I see what you're saying ! I guess the main question is the stars after 70% then... Because if the Pentax PCF is nice up to 90/95%, and the BA8 is nice up to 70%, that is about the same usable "eyeballing around" FOV in both binoculars plus you get a multi purpose center focus......


    So the main question is if the 12 degrees extra AFOV (Which is the more desirable feature in my opinion) is worth all the trouble of the focuser,weight and price.
    Anyone here who have used both a BA8 and some other 50 Degree porro ?

    Thanks !!

    Edit: Thanks Bryan ! That was helpful, I might just get one soon !
