Hi

Age makes you wonder about many things, many of them not about astronomy, but a lot of things that are about viewing. Have any of you gone from telescope viewing to using ONLY binoculars, not only because of the light weight, and the way you can just walk outside and start looking up, but also how it makes it easier on your eyes using both eyes. I guess it could be a nice change, especially if you have observed the planets and high power all these years, it could be nice just looking at greater swaths of the sky in a different kind of beauty.

Maybe but not to me. There is binocular viewing and there is telescope binoviewer viewing. Basically the same effect to your eyes. Everything else being equal your eyes will prefer both eye viewing to one eye viewing every time. As for the weight my main pair of binoculars is a pair of old Vixen 11x80s. The lower power enables me to hand hold them or alternately lay on the ground or a lounger and use them with my elbows propped on my chest. But even at 72 I won't give up the telescopes to only use binoculars.

I still use many scopes, but I do like binocular viewing for the immediacy and absence of set up time.  Often the weather will clear for an hour or two, and a major scope set up (and cool down) does not seem an efficient use of time.  Or sometimes one is just too busy or tired for an extended observing session.  At times like these binos are an excellent option.

I have a couple of 80mm ED scopes that I use for those quick sessions.  

 

But some nights, I will just grab a pair of binoculars, put a chair out in the backyard and just peacefully enjoy the night sky.  

 

I have a number of binoculars so what generally happens is that 15 or 20 minutes into this peaceful journey, I decide I would like to compare the current pair with another pair. I just grab a patio chair and it's on one side to I store the binos I am not using... Another 10 minutes and I decide to try another pair for comparison.  

 

It continues.  At some point, there's a second chair on the other side and 7 or 8 binoculars in the rotation. 

 

I like binoculars, I like older binos and newer binos.  Fortunately (or unfortunately, depending on whether it my point of view or my wifes), Jack (Foss) lives about 10 minutes from me.  Jack often has classic binos for sale at very reasonable prices...

Actually, Yes, that's substantially true for me --- I pretty much abandoned regular monocular telescopes in favor of binoculars. Thing is, I didn't want to give up those things that require aperture and magnification... what to do, what to do... So I bought and used 7x50 binos, and then gradually filled in smaller and larger ones:

 

Vixen 2.1x42 (effectively 2.1x13) constellation binos

Zeiss 8x20 pocket binos

Zeiss 10x25 pocket binos

Zeiss 7x42 handheld binos

Zeiss 20x60 handheld binos

APM 100mm ED APO binos

JMI 150mm True Binoscope

JMI 400mm True Binoscope

Night Vision 1x True binos

Night Vision 3x True binos

 

The only regular telescopes that I kept are a 4-inch refractor and a 36-inch reflector. And I got a Binoviewer to use on those, with pairs of eyepieces, including a Night Vision pair!

 

Ehhh... I don't think I need anything else...    Tom

I first got seriously into binocular observing back in the years 1992-1993 and I had acquired enough pairs of binoculars by then that I could easily spend several hours per night observing with them.  And yes I much preferred observing with binoculars than with my

telescope.  At that time I was also considering selling my telescope and using the money from that to help fund the cost of acquiring a pair of Carl Zeiss Jena 40x80 Aspectem binoculars.  However, I just couldn't reconcile myself to the idea of no longer having telescope because of the good things it could do for me that my binoculars couldn't so I decided to keep my telescope and pass on getting the pair of 40x80 binoculars.  In the 27 years since then I've never regretted having made that decision.

 

Two years ago I turned 70 and decided it was time for me to downsize my telescope, mount and eyepiece set and since then I've also not regretted having made that decision.  I still use my telescope a lot for observing the moon and planets from my backyard and I also take it with me when I drive out to dark sky sites to do deep sky observing.  The telescope very nicely compliments my binoculars because between its larger aperture and higher power capabilities and it show many individual deep sky objects much better than my binoculars can.  On average I probably spend about 60% of my time observing with binoculars (when I'm at a dark sky site) and 40% of my time using the telescope.  

 

That combo just works so well for me that I know that I could never be satisfied if I could only observe with just my binoculars and not also with my telescope or vice versa.  Lastly, for some binocular observers who may have larger scopes now that they now find to be burdensome, consider downsizing your telescope.  If you have one that is smaller, lighter and easier to store, transport, setup and take down then it becomes more like your binoculars.  That is, easy to use (while also providing some very useful capabilities that binoculars can't match).

I'm not sure if this qualifies, but back around 1965, my ( now lifelong ) passion for long distance daytime terrestrial viewing led to me convincing myself it was a spotting scope that I needed.

 

After a few weeks of use, the 35x60 straight - through drawtube scope which I'd been pestering my parents for proved to be an exercise in frustration more than pleasure.

 

My dissatisfaction was a result of the insufficient quality of the scope as much as anything else.

 

My dad persuaded me I'd be much better off with 10x50 binoculars, and somewhow managed to convince the mail order company that the scope was defective and if I remember correctly, arranged a part exchange arrangement involving a relatively small amount of cash plus scope for the brand new 10x50 Telstar binoculars.

 

The transformation was instantly gratifying and in spite of it's relatively modest quality, narrow 5 degree TFOV and short eye relief, that clunky 10x50 served me well for around 30 years.

Yes,

 

I am moving into the direction to be more binocular observer than mono-observer.  As today, i observe 80% of my time with binoculars of several apertures, mostly hand held and only the 15x70 mounted on tripod. 

 

There is some learning (and fun) on comparing the views of the same object through the different binoculars defining the minimum aperture for resolving the objects. 

 

On the other side, as my eyes are not from the best batch, i am seriously considering to buy an affordable binoviewer for testing in my two current scopes, the main reason is to get relaxed views.

I thought hard about a telescope, but decided to go with binoculars first. I don't rule out ever getting a nice small telescope, but right now I am very satisfied with just sticking with binoculars. My 20x80's do a fine job. I've learned a lot about navigating the night sky. The other night I looked at the nearly full moon and got stunning views. So I'm pretty satisfied with binoculars.

Age,the lack of ability to handle the cold weather and the ever increasing light pollution means that I use binos instead of a scope at a ratio of around 10 to 1,watching.gif  D

As I've said before, two eyed vision defects, including inevitable effects of aging , can be minimized by the brain recreating the visual field from the information combined by both retinas.

Provided 1. they are excellent top-tier binoculars 2. I can’t use the scopes anymore 3. The key as the OP stated is looking at the sky , not just objects.

Telescopes can be quite effective for looking at the more than just objects.  Binoculars tend to be limited by the need for eyepieces to be side by side.  Here's 50 mm that does ~10° at 10x with a 5.3 mm exit pupil.

I use telescopes and binos for viewing the night sky in large chunks and telescopes for smaller chunks.  I'm almost 72, three years ago I downsized my largest scope from a 25 inch F/5 to a 22 inch F/4.4.  It was a good move.

No, but its safe to say I use binoculars on many more occasions. I use binoculars morning, evening and night. I generally use a scope to look at the night sky a few times a month, when my life, the stars and the clouds all align. My binoculars won't do what the scope will. But I use binoculars to look at birds in the yard and phenom in the sky, in the construction of interesting landscapes, bringing bugs up close - you name it and I look at it thru binoculars. 

Last week I watched four coyotes leisurely hunt for mice in a field thru binoculars. (Too bad I didn't have a scope set up.)

Since after a mile, what comes in both barrels is practically identical,

the binoviewer works and still gives you the signal processing

where defects in one eye lose out to the other eyes (ie, floaters, cornea dust, etc).

 

A little catch though: tho get the same brightness as the binoculars,

you do need a bigger objective.  ~40% more diameter.

That can close the gap in price towards the binoculars..

Wow...2 monoculars, or even the two in series!

For that to work you'd need extra resolution.

Neck comfort keeps me liking telescopes, not having to look up. Down into a Newt or diagonal is painless by comparison. 

 

But I do like wide field views. My first refractor was & is a 500mm, first eyepiece a 32mm Erfle. They will be the last as well I expect, peaches & cream - maybe a Barlow too.

 

I have a bino viewer to use if wanted.
