Help on good binocular setup
Posted 17 December 2003 - 08:14 PM
I ran came across some extra money and instead of blowing it on more Christmas presents , I was wondering about getting a good binocular setup instead. I have a 120mm refractor, but will be selling it soon because my right eye took some damage a while back so I don’t really use it anymore. I dont want to lose too much aperture, so I’ve been looking at the Oberwerk 22x100. But with my "luck", a 120 bino will probably come out next year! I have around $1200 to spend, so if anyone has a good setup to recommend, let’s hear it!

But with that amount of resources, you could look at more exotic sets - and www.bigbinoculars.com is a good start.
You might try a posting on AstroMart and see if you have any responses/suggestions....

Just to ask the question, why not view with your left eye?
Might take some practice so it doesn't fatigue quickly, but it should be trainable.

That leaves you with $800-900 for binocs.
It'll probably cost you at least $50 to get it all shipped, So maybe you should look at binoculars in the range of $750 to $800.
There are a few reviews of the Oberwerk 22x100s.
Depending on your targets, you'll get more gain from premium glass and coatings and additional magnification than you will from aperture.
Don't be too concerned about giving up some aperture. The magnification in binoculars is generally so low that the primary loss as compared to a scope is not in aperture, it's in magnification.
A binocular at 20x compared to a scope at 80-100x will see about a full magnitude or more lower.
A 100mm binocular (viewing at low powers of 20x to 25x) vs a 120mm binocular at the same powers will see only about 0.3 magnitude lower.
A binocular at 25x vs another binocular at 20x will see about 0.3 mag deeper. You can easily make up for the 20mm difference in aperture by a 25% increase in magnification.
There would be a difference in faint diffuse objects. The larger aperture would gather more light.

Edz, if power is more important then aperture, what would you recommend? I don’t think I want the fov to be smaller then 3. I looked at the Fujinon 16x70 but I can’t find a place that ship overseas. The shops here demand a PREMIUM price (~$1450) - far more then I’m willing to pay for them!
I was thinking about getting a parallelogram mount. I already have a sturdy wooden tripod, but I don’t know if I will be able to use it, since it has one of those metal "thingies" that lock the SP mount in place.

I don't own the 22x100, but I have seen them. They are the same body as the 20x80 Deluxe which I do own. They have a short range on the right eye diopter adjustment, unless it's been recently modified.
I also own the Fujinon 16x70. It's pretty hard to beat the contrast in these binoculars, even with a higher powered view.
APM Germany sells the Fujinons.

I have one more question; Do you (or anyone else in here) know if there’s anyway to attach a narrowband filter to the 22x100?

I think you'll be pleased with the Ober 22x100. I don't know of any way to attach filters to binocs with fixed EPs...at the least, they'd have to go externally, and there'd have to be some kind of homemade adaptor to secure them.

I have my 11x70's on a parallelogram mount. It is a great way to view. No arm strain, easy to move around etc. To view overhead you still have to bend your neck back a long way unless you rig them up next to a reclining beach type chair.

Well I ordered the 22x100 today and of course felt bad straight away. Buyer’s remorse sucks big time, but I’m sure it will go away when I get them!
I didn’t order a parallelogram yet, because I have a question. Both the Unimount Basic and Unimount Deluxe can take the same load. What will the 6 degrees deluxe model have over the 4 degree basic one? Most seem to go for the deluxe version. I’m not being cheap here, but why fork over twice as much $ if you don’t have to!
On the filter issue. Are we talking normal filters here or are there filters made specifically for binoculars? I read somewhere that someone removed the filter from the housing and put it under the eyecup. Supposedly it worked just fine. Is this what you mean, Ed? Now reading Rusty’s comment, is there anywhere we can get HQ eyecups or do we have to use super glue? I see the Oberwerks are only $10 so I’m assuming they aren’t top quality stuff.
