    Default A difficult decision to be made!



    Although i have quite a few pairs of binos already i wanted to get some quality ones. I was after some WILLIAM OPTICS 10x50 but it seems no dealers in the UK had them. In the end i went for a 7x50 helios apollo. I then thought maybe the helios apollo 10.5x70 are better. So i ordered them as well. The problem is i now have both pairs - love them both and have to decide which to send back!

    Helios Apollo 7x50 - binoculars specification - allbinos.com

    Helios Apollo 10.5x70 - binoculars specification - allbinos.com I think these are exactly the same as astro physics ones .

    I was initially shocked by the weight (1.6kg) of the 7x50 but within a day was able to hold them without any arm fatigue. The 10.5x70 were the same (2.6kg) but again sitting down in my recliner i can hold them steady without fatigue in most positions.

    I really like them both as strangely i see them as completely different. The first time i looked at the sky with the 7x50 i was amazed how clearly it showed the colours and that Tarazed, beside Altair, was so obviously orange. I have looked at it many times with other binos and it had never jumped out at me before. Unfortunately since the 10.5x70 arrived it has been 95% cloud but even the views between the clouds blew me away - so many fainter stars visible and both have pin sharp images for nearly the whole fov. The depth of field that remains in focus with both pairs is also incredible - with all my other binos in similar situations you would constantly be adjusting focus. Previously my best binos were some wide angle nikons but both of these are a massive step forward on them.

    Anyone been in this situation before? What did you do? Any suggestions as to how to decide. Unfortunately they are both fairly expensive - so one should really go back.

    I don't know much about Bino's, as evidenced in my signature, but I would say Keep the lighter pair if things are close in comparison because none of us are getting stronger or more stable as we get older and what is manageable weight-wise today may be cumbersome and tiring in the years to come...Just a novices opinion but an opinion nonetheless ...

    I have a pair of 15X70's. I consider myself still on the youngish side and stay in shape, but if you want to look at something at for longer than a few seconds, my binoculars get heavy pretty quickly. So I agree with DAVIDAMONETT, weight is an important factor.

    For how long could you wait to return a pair ? Could you cope to keep the two for a time until decision ?

    For my experience I know the only way to discover the one that will be used most is with real observing time, after some months with the two you will answer this question with no regrets.

    Cheers guys, unfortunately i can only really keep them a day or so longer. I know if i could have them a month or two it would be obvious because one would just be used more than the other. I think weight may well be one of the main deciders. Bad planning on my part because i have them around a full moon so can't really see their full potential. Anyway will post what i decide and do a proper "first light report" on them in the binocular section in a week or so

    So, I might be going a little against the grain here... but I would say keep the 10.5x70 and send the other back. I have a couple reasons for this:

    1) You will never regret having the extra light gathering power, and the difference in magnification isn't huge.
    2) The binoculars have a tripod exit on the front, so you can use even just a photographic tripod to help hold them for you. Just takes buying the L adapter (around $30 or so).
    3) The 7x50 have an exit pupil of 7.1mm whereas the 10.5x70 have an exit pupil of 6.66. 7.1 is fine if you're quite young and have perfectly light adapted eyes, the 6.66 however will allow you to actually see the light gathered by those big 70mm objectives. Images will appear even brighter in the 10.5x70 binos than the 7x50. As we age, the maximum dilation of our pupils goes down, so the smaller exit pupil will help.

    Hopefully I was able to chime in early enough.

    The 10.5 x 70's will certainly let you see more faint DSO's if you can handle the extra weight (2.6 kg as opposed to the 1.6) as you reported. My 10x50's greatly aid in finding the brighter DSO's - up to magnitude 7.5 or so even under some light pollution. The greater light pull will definitely be worth it if you stay with the larger ones.

    Well an update - decision made and probably for all the wrong reasons!

    The 10.5x70 are a fantastic pair of binoculars that give exceptional bright crisp images. Moons of jupiter were able to counted and Albireo was resolved to 2 stars and that was hand held and with moonlight (nearly full). However they have gone back

    To get the best out of them (and i'm sure it would be brilliant) they deserve to be on a mount at least some of the time and they did not fit my mirror mount - if they had it would have been a different story. Also there is no denying their physically large size - they would not be safe on the window shelf where i usually leave my binos and they come in a strong aluminium case which would just about completely fill my hand luggage case when flying, meaning that it would be a problem carrying other things. Also i have the 10" dob which lives outside and can give me 2.2 degree FOVs and i can be viewing with in the time it takes to lift the cover off, attach the telrad and fit an eyepiece. Probably quicker than getting a tripod outside and attaching binos to it. And lastly i'm hoping to eventually get a 80mm or 90 mm short tube refractor for AP so politically, with regard to household expenditure, the wife is more likely to be sympathetic to that future goal knowing that i sent the very expensive ones back
    If someone bought the Helios apollo 10.5x70 i am sure they would be delighted with their build quality and performance, but i would recommend one of the various types of mount to get the very best from them.

    Will post a review of the 7x50 in a week or two on the binoculars forum.
