Greetings! Can anyone give sites that will show images of the night sky as seen through various size binos? If possible, these images should be one image, without stacking and colors. I'd like to see the differences in 10X50,16X70 and 25X100. When I view astrophotos, they are from telescopes. I still want the Fujinon 16x70 but have no idea what could be seen and how large the object will be - a pin point or ? I don't expect to see a galaxy, like with a telescope, but would some show the spiral shapes and would I strain my eyes to see them? I thought there might be a site that shows these actual images, but haven't found one. Thanks!

Look for people that sketch... It will represent the closest to what your looking for.
25x100's are leaps and bounds better than the others I can assure you. 25x100's come close to 6" and 8" scopes on galaxies in my opinion. Maybe even better on say super extended objects like Andromeda.

Thanks for your time and comparisons; however, I would like to see pictures that would actually represent what I would see with a 16x70. When looking at some pictures, from various size telescopes, planets are extremely small as well as some other objects. I realize there are many factors to consider, but if someone could direct me to a few pictures in this site's gallery that might be similar to a view through the 16X70 Fujinons, I would really appreciate it. Thanks for the help. The stores don't have the Fujinons in stock!

Wow. Photos totally fail to capture what it's like to look through a telescope, and that's 100X truer w.r.t. binoculars.
Based on your post -- yes, you would be disappointed. Your sig says you live in L.A., meaning that galaxies will be very hard to make out at all. In fact, all but M31 would probably be impossible for a beginner. And even under absolutely pristine skies, to a super-experienced observer, I can think of only one galaxy that might show a hint of its spiral structure through 16x70 binoculars -- namely M33.
Almot across the board, 10x50 binoculars under dark skies will show you more than 25x100s in the middle of a city. The one exception is certain coarse open clusters where the extra magnification of the 25x100s will overcome the handicap of light pollution.

The quest to find illustrated or photographic comparisons of different binocular magnifications of the same target is a noble quest--and would certainly help many of us visualize which binoculars to purchase. The best comparisons I have found in the past are the following photographic comparisons of day views: Celestron Magnification Comparison Chart and Zeiss Binoculars 101 .
As suggested in another post, the best visualization of night sky views may be found among sketching artists, such as Rony's Binocular Icons . Rony does not show you comparisons of the same target through different magnification, but what he does reveal in his binocular sketches is truly amazing. Many of Rony's sketches reveal what can be seen through 8x56 and 15x70 binoculars, and I must say they are very close to what I have seen. Rony can be found in the Cloudy Nights sketching forum under the screen name of Rodelaet. If you send him a personal message, perhaps he can assist in some way.
To answer your question with certainty, you may need to order the Fujinons FMT-SX 16x70 from an online vendor with a liberal return policy. That is what I did a couple of years ago. Impressed by the Fujinons, I decided to keep them and soon ordered their 7x50 model.

You could see Andromeda galaxy (M31) without binoculars under dark skies but to see any spiral shape you would need a telescope or at least a very large pair of binoculars like the 28x110's under dark skies.

At Bigbinoculars.com they have one very neat page with terrestrial images showing different magnifications through the same binoculars. It gives some idea of the effect of increased magnification. Although it is not exactly what you are looking for, I find it instructive.
It is here: http://www.bigbinoculars.com/onemile.htm

As it turns out, I just finished compiling an Excel Spreadsheet of the 52 best binocular objects as determined by a poll late last year here on this forum and on the "BinocularAstronomy" Yahoo Group.
In addition to the spreadsheet I have images of the more popular objects "as seen" thru 10x50's with a 6.5 degree field, 15x70's with a 4.5 degree field and 25x100's with a 2.5 degree field.
One shortcoming, in particular for the emission nebula objects is I did not subtract out the color, and the nebula extent is too great as these are CCD images, not a representation of what the eye sees in real time. The images are useful in that they do give one a good sense of what objects should look like field wise.
Another shortcoming is the images do not fairly represent what the magnitude reach of each size binoculars are. Some may still find this to be of some interest. I will post an image to give the group an idea of what each image looks like.

I'm impressed! That gives a pretty good feel for the progression from smaller binoculars to bigger ones.
A few caveats. First, your mileage will vary tremendously depending on light pollution. In really bad light pollution, you'll see significantly less than these pictures suggest.
Second, these are analogs, not the real thing. Remember that that one-inch circle on your screen will expand to a whole surround-view experience through binoculars. You'll see the stars of the cluster spread much farther from each other than the pictures suggest.
Finally, under reasonably dark skies, I'd say that these pictures seriously under-depict the grandeur of the Double Cluster. Make the left-hand view 7x35s, the center 10x50s, and the right-hand view 15x70s for an analog that's more faithful to my experience.

I do agree with the points made by Tony. In short, nothing beats getting up close and personal with these objects. Viewing a photo is not the same as looking at the object thru a good pair of binoculars under a good sky.
Anyway here is another comparison image -

The #1 object on our list? The Pleiades, of course. Note that the binocular view would not typically show the blue reflection nebulosity. Some say they have seen it thru binoculars under excellent conditions.

Barry...
Nice photographs. What is the aperture of the telescope through which these photographs were shot?

Thanks for these Barry .
If anyone , like myself , has the free software programme called Gimp2 on their PC ( downloadable in minutes - just google for it ) then one can have lots of fun transporting photographic images like Barry's into it , and applying various colour and filter effects to make the images represent a very wide range of variations closer to what is actually seen through binoculars , particularly if one eases back on the colour saturation a touch , then darkens the image slightly .
Then a normal edit process in Paintshop can stretch the images to more accurately represent the all - important aspect that Tony mentioned of the image FILLING your field of view .
The stars do tend to lose some of their sharpness by doing these things , but the end results are probably closer to what is more typically seen in reality in light polluted skies than the photos above .
It would make an interesting project for someone .

I'd agree Tony, the right hand pic of the double cluster does look more like a 15x70 view, and under mag 5.5 and darker this object(s) looks more spectacular than the pics suggest.
The M31 pics are quite accurate, although like the pleiades, a bit "deep". Thanks again Barry for taking the time to post this.
