Largest bins you can hand hold

Largest bins you can hand hold

Postby philip pugh » Sat Feb 27, 2010 1:33 am

I regularly use 15x70s and don't need a tripod. Most people claim that 50mm bins are the largest. Mind you, I'm a big bloke and been using bins regularly for 15 years. Best pot so far was seeing the spiral structure of M81.

"Can hand hold" and "are sensible to hand hold" may be completely different ... for astronomy purposes I reckon anything over 6x really need support.

HI There,
I would say the upper limit would be 10X50's.I have 7X50'which are a bit heavier than my 10X50's but are easier to use as the lower power more than compensates.
Regards Les.

Perhaps using 20x50s for starters helped me develop a steady hand. I find 15x70s quite good for "grab and go" observing. If I have time for a longer session, I have a Startavel 80. I do have the camera tripod mount but really need a camera tripod that reaches higher. Could be useful when I'm travelling. I'm off to the USA next month, so they'll be coming with me.

10.5x70's weighing 2.5kgs can be used with out tripod but Boy do the make your arms ache very quickly. 15x70's can be used hand held but you will want them held steady if your going to see clearly what your looking at. ide say 10x is the highest practical magnification for hand held 12x with support ie a wall, washing line post, window sill somewhere you can rest your elbows is ok. if you want more Xpower a tripod is needed

My car's quite good for that, as they live in my car most of the time. I once got stuck on a clear night at a dark site waiting for the AA and boy, did I wish I had them with me, then! I can't use a washing line. I can just imagine my wife's expression as she examines the bent support!

As an aside I've just used them to check the Sun for sunspots. Didn't see any but often do. Should mention I use Baader filters, just in case anyone uninitiated is reading.

I have briefly hand-held a Fujinon 16x70 and a Russian 20x80 (both hands on RHS, left barrel resting on left forearm). Sure, you can make out things, but....

My "around the neck" binoc when I'm observing is 10x42 and I seemed to be able to hand-hold it rock-steady -- until I mounted it, and realised just how much I was missing when I hand-hold it. Not a problem since I use it as a quick "grab and go" and as a "get the right region of sky" for when I am star-hopping with a telescope or the big binoc (20/37x100, and no, I don't try to hand-hold it -- it weighs about 7kg! [:D])

i tried hand holding 25x100's a few times... which as you can probably guess is just a silly idea.
i have rested my 8x42's on fence posts when out during the day trying to resolve something at the limit of my eyesight and the binoculars resolution. simply mounting binoculars can make a huge differance to what you can see. its allmost like boosting the magnification and you can read signs you couldnt when hand held. the higher the magnification the greater the affect.

7x50 is my perfect hand hold bino or the Zeiss 8x56.

I struggle with my 10x50's for long periods, I either tripod mount them of prop myself against a post.

One favourite although I sold them many years ago, a pair of Russian 8x30's. A good balance of magnification, light gathering and weight.

Regards
