Monocular HELP!!

So my head is battered looked at so many monoculars, I require a zoom monocular and I am partially sighted and 10x is just not enough.
I own an old Bepkyn 10x46 but its old and plastic and fogs so I just use for watching football.

I also own a yukon 20-50x50 and its brilliant BUT to big to carry when carrying the Nikon D7100 & 300mm F4 it all just becomes to cumbersome
http://www.amazon.co.uk/Yukon-20-50x.../dp/B0002HBORE

So I require say a 10-30x30 but a bigger front element for light would be better, I can find some cheap Chinese ones that I just would not trust.

I have tried quite a few (fixed magnification) monoculars but found out that they are not ideal for birding, so I am afraid you won't get too much help on this forum----most people stay away from zoom binoculars, so I would guess very few would consider zoom monocs. An alternative that you might want to look at is a 10x IS monoc---IS might help you see more details despite the lower magnification.

Thanks.. I wish I could use binoculars it would solve a lot, my yukon zoomed to 50x means I can just see say a Kestrel on top of a tree that others can see with the naked eye. So 30x is my bare minimum requirement really but greater than 30x means I am back into spotting scope territory and not monocular.

Its a nightmare situation and I know its a strange hobby for someone with sight issues

A Zenica 8-24x40 might be your solution, if you don't mind an AFOV of 40 degrees. Cheap, metallic, precise, lots of eye relief, no CA, tripod adaptable, usable up to 24x (and great between 10x and 16x). If it had 60 degrees it would be a miracle.
Zoom in monoculars and spotting scopes works because there ain't collimation issues. There are AFOV issues though, unless you get the Leica Aspheric zoom.

Brilliant thanks I will give it a look

I guess sacrificing front optic for magnification will be my best option rather than the other way around

Small eyelens means narrow eye relief. And any exit pupil under 1mm is unusable, you will only see the floaters of your eye. So, even if it had good optics (doubtful for that price) it would max at 20x.

Thanks and I do have plenty eye floaters :(

After much searching I like the look of this magnification and optic size, even unit size is not to big but I can't find much about it.

The Visionary may not be as bad as stated. Try it.
I have used most of these monoculars, which are sold under ten different names. Zooms and fixed..
A bit rough mechanically, backlash.

Would a 500mm f/8 good mirror lens plus old monocular converter, Japanese 10mm work for you. little eye relief.

I doubt you can hand hold 50x.

There is an IS monocular, might suit. 30mm I think, different magnifications.

I have most of the Yukons, they are not that big.

What about a Nikon P610 camera.

P.S.
A 300mm f/5.6 or rarer Minolta 250mm f/5.6 mirror plus monocular converter, old Japanese are small.

The Opticron MM2 spotter is small. May be best solution? Also ED.

I am at a loss looked at so so many monoculars and binoculars, I had hold my yukon at 50x fine, lots of practise.
even looked at some super zoom binoculars just cheapies I know quality is poor but for bird location it could work.

Here is one, that has all the bases covered. Even a ruby colored lens.

This should be a good one to use.

Skirge,
What you seem to need is magnification above all else, then brightness.
The Yukon is a folded refractor, lightweight.

I also thought a cheap 50x or 30x zoom binocular might work.
I have the Yukon 30x50 mirror binocular and I like it a lot but it is a bit heavy. It has very high resolution.

Horace Dall made dozens of pocket, powerful folding telescopes, some now in the Science Museum. These would probably be ideal, but the relay erect image lenses are difficult to make and only adjustable by master opticians. I don't know anyone who could make you one. He also aspherised everything.

The Nikon P610 viewfinder might work for you as well as good for photography.

If the Yukon works best, it might be better to stick to that.

An 8x monocular is too low a power.
I have the one shown minus ruby coating.

Good luck.

I wouldn't use anything 10x or above as handheld.
Monoculars shake even more than binoculars.
My favorites are 8x30s I made from IF binoculars,
followed by a 7x35 xwide monocular I made from CF binoculars.

If you crave power, a light photo tripod and this
beauty might suffice:

http://www.amazon.com/Yukon-Scout-20...ds=yukon+20x50

A sweet 20x50 spyglass with 1/4-20 threads for tripods.

But....I would never hold it freehand.
Maybe braced on a tree or with a monopod.

I think you also mentioned once that the atmosphere has trouble
supporting 50x anyhow. Some days, and over 300yds, I might add,
even 30x is a challenge through mixing air.

Oww my head. I have spent the last 2 days now looking at Binoculars I have always struggled with bins but had a pair of 10x25 I was given so did a bit of practise finding a technique I could get used to.

From what I have read on here zoom binoculars are frowned upon but I feel I may benefit from zoom more than fixed.
O am a Nikon lover I have to say, yes of course I would love Carl Zeiss or Leica BUT WOW HOW MUC!!

So I trust in Nikon and really liked these

Nikon Aculon A211 10-22x50 Zoom Binocular
119 in Currys at the moment

I did get a nice surprise I had forgot that the NHS had very kindly ordered me this and it arrived on Saturday, very clear optics but I need brighter
Schweizer 10x30

Skirge clearly says that he hand holds the Yukon at 50x.
It is due to the shape, size, weight, both hands and experience.
I had no trouble hand holding for years the 25 to 40x 2 1/4 inch Broadhurst Clarkson drawtube scope at any power. Maybe bracing.
The 30x50 Yukon drawtube is not as sweet as you think, but might suit Skirge.
The old 20x50 Russian drawtube scope is much better optically centraly, but narrow field. Easily handheld.

I have the Nikon Action 10-22x50. Similar to Aculon. I think you may like it. But try it first at Currys. It has false colour at 22x, but this may not bother you. I use it for Jupiter's moons. I brace it against the double glazing.

Skirge. Can you ask the NHS to get you the Mirage Beechers 7x30 binocular? If you don't want it pass it on to to me, he says jokingly.

Dear Skirge,
Joking aside, I think that you may truly benefit from a Beechers Mirage 7x30 or 8x28 binocular or possibly monocular, right or left half.

Your eye specialist could prescribe this for you on the NHS hopefully. It is specifically a low vision optic. Some are wide field.

Thanks.... . the NHS has a very strict product list of what is available to them, 10x was the most powerful monocular they had I was hoping for say an 8-30 x30 but sadly no joy.


The ability to zoom for me is a must the more magnification the better, I am even mulling over the idea of getting rid of my prime 300mm lens + TC and looking at a zoom to enable me to more easily locate the birds in flight. On Saturday I missed a great shot of a Short Eared Owl carrying a short tailed vole as I just could not locate in the lens.

This is my work, I do okay must there could be so many more better shots if I had better gear, I do have a superb mate/carer who is amazing at directing me to the bird but so many times I just can't see it.

Skirge,
Your photos are great. You have better Moon eclipse photos than I got. The bird photos are beautiful.
Personally, I would stick to the gear I have. The 300mm lens is great and your Yukon 20-50x50 seems fine.
It is fruitless for most people to just chase new gear.
If anything I would add anything useful, perhaps the Nikon 10-22x50 if it works, rather than replace anything.

Well done with your photos.

Many thanks.. I am a new gear chasser I have to say and the new Nikon 200-500mm really does interest me greatly. I will put a bit more thought in and go to Currys see if I can try our the Nikon bins so how they are for me.

Thanks for all the help everyone

Hi Skirge,
Would the Yukon 16-32x36 be useful?

OVL have or had cheap lightweight blue 15-45x50 and 20-60x60 spotters, but I don't think as good or better than the Yukon that you have.

Last night tried Turist, in Cyrillic, black metal 8-20x32 on Jupiter and Venus. Jupiter clean disc no false colour.
Probably ~f/7 and relay lenses. Fixed field 5 deg at 8x, 2 deg at 20x. Parfocal, rotating zoom.

Length in plastic waterproof container 335mm.
Smaller version of kkokkolis photo 40mm scope.

Made in USSR. mainly uncoated, but very good optically.
Saw some Jupiter moons despite light sky.

Venus to Jupiter 16.45 deg in Bushnell 4x21. Mars also in field. 06.22 UT. Perfect conditions.

Thanks guys right now until I can decide I have tried to find a way of attaching my old blackrapid strap too my Yukon to try and make carrying it a bit less of a hassle. Weather been dreadful so not been able to go out and try it yet.
