I’m partially decided to buy a pair of Oberwerk 15x70. The option would be Oberwerk 20x80 LW.
I have not been able to find a comprehensive comparison / shootout between the two.
Price difference is not much of an issue and the same mount should be able to handle either pair.
This would be my first pair of binoculars (not counting my Focus 8x21).
On one hand I would probably benefit from the wider field of the 15x70’s, making things easier to find. And there would be more room for upgrading to a bigger pair later. On the other hand I would like to be able to see as much as possible with the best possible view right now. Then again, to be able to fit some things in the FOV I would need the smaller pair, so maybe I would like to have them as well as a bigger pair.
OK, I admit I’m confused. 
Is there some kind of optical technicality that would make me want to go for either of them? The 20x80 LW’s are longer, more sensitive and more likely to go out of collimation, right?

I'd put my money on the new improved Oberwerk 15x70s. I've never seen the 20x80 LWs, but then again, I've yet to see a set of 20x80s that I liked. The 15x70s on a good mount that allows decent mobility is a tough act to beat.

Since one purpose would be to learn the skies and help me find things the 15x70s would make much more sense I guess.
Would I need a red dot finder or is the field wide enough to just aim and look? I’ll put them on a mount of course.

I have the Obie 20x80 standard and I can tell you that I absolutely love it! I have a finder mounted on it and star hop around to find what I’m looking for. It has worked great so far. The 15x70 has a wider fov so it would be easier to "point and shoot" with I guess.
Btw, you are smart buying from Oberwerk. The binocular have to travel a bit and bad things can happen to it on the way. That’s what happened to my binos. However Kevin was very professional and one week later I had a new one (I hadn’t even sent back the old one yet!).

When I ordered Oberwerk 15x70s from Kevin, I was accidentally sent 11x70s. I got in touch with Kevin, and he immediately sent the 15x70s & told me to send the 11x70s back (postage paid of course) when I received the correct binoculars. It's a pleasure dealing with folks like that!!

I've been an Oberwerk booster almost since inception. But, it boggles my mind that folks say things like the above. Let's face it, sending out wrong or improperly calibrated merchandise, and then offering to *fix* it is NOT customer service. Customer service begins with sending out the right merchandise, so the customer doesn't have to hassle with the whole return item thing that is now so prevalent. Any merchandiser that puts forward that they have great customer service because they handle returns deserves to fall flat on their face. Great customer service is evidenced by a very minimum of returns.

I guess I'll voice a differing opinion. If this is your first pair of binos (not counting the 8x21s) and you want to use them to help learn the sky -- I would recommend something that is hand-holdable. The 15x70s may be quite nice, but they will have to be mounted to be of any real use. Instead, I would recommend some 10x50s or something along those lines... allowing you to add something larger later on.
There is usually a tendency to get big binos right off the bat, when they may not be the ideal fit for the application.
I sold my 16x70 Fujis because I really needed something I could hold, and not have to use on a mount. I use binos to assist in the star-hopping process. I am currently using 9x63, and they are at the maximum end of what I can easily hold still.

I live by my red dot Actually, it's a great combo with binocs - once you learn were things are with the binocs the red dot makes it trivial to point the scope there. Accuracy is very good - if it's covered by the dot, it's in the viewfinder, even at 100x.
Perhaps it's because my scope is dob, and my widest angle is still up at 44x, but I can't imagine getting the scope pointed at things without the red dot.
On the binoc front, I've got the 11x56's - great binocs, nice wide 6 degrees of view, but just on the edge of hand-holdable, in my opinion - If I'm trying to get a good look, I'll often try to find a post or window sill or something to steady the view with.

I do agree with that, but I also understand that mistakes will inevitably happen. If a company was notorious for messing up orders or something like that, I wouldn't deal with that company in the first place. But the majority of astronomy-related businesses that I've heard of seem to have excellent reputations. This being the case, I honestly don't mind a simple little mistake once in a while, as long as it's dealt with satisfactorily.
By the way, the box that the 11x70s were shipped in had a 15x70 sticker on it.

Peter, Thanks for your advice. I appreciate and respect your opinion, but personally I have found that I don’t like to hand hold binoculars for any duration of time, even if they are small. So I think will start off using a tripod anyway (while plans for homemade P-mount and star chair evolve as separate projects).
It really would be a lot easier to convince me to go for bigger rather than sub 70 mm aperture. More is more, right?

Doug,
Do you have a red dot finder on 11x56 binoculars?

lahoj,
I guess it all comes down to personal preference and intended use. Occasionally I just head outside with binos to scan the Milky Way... but my regular use is in the star-hopping process with my 33 cm Dob. I use the binos to orient myself in a star field to plan the next hop at the eyepiece. The binos are around my neck and I hand-hold them. It would be an interruption to the process -- for me -- to have to walk over to the mounted binos and back to the scope.
Enjoy using whatever binos you ultimately choose!

I'll put in my vote for Red Dots. If your binos need a tripod, get a red dot finder. My big binos sit on their tripod right nearby my scope. As I have mentioned in other posts, it has been getting the most use of all my equipment.

Lahoj,
Go for the 15x70 binos. If and when you get ready to jump to bigger aperture then you will probably consider the 100mm size.
I went through several different pair of binos between 50 to 70mm before settling on 22x60. I mount them on a parallelogram mount with a red dot finder and that satisfies my needs perfectly for the present time. I also have a scope but use the binos 95% of the time since it is easier to set-up and take-down. I also enjoy viewing with both eyes.
I have purchased Oberwerks from BigBinos in the past and they are good. I have also heard good things about Burgess. And I have purchased Pentax binos from Astronomics and they were also a good company to do business with. Perhaps you have already done a search here on Cloudy Nights of the various vendors.
I think your initial reasoning for getting the 15x70s is good. Best wishes for clear skies and many hours of enjoyment with your new 15x70s.

Hawkeye, Oberwerk will take international orders. Here's a link to their info.

I would suggest contacting Oberwerk and see if there's an Austrailian distributor near where you live.

No turning back now. I have ordered a pair of Oberwerk 15x70.
Oberwerk and most vendors have them on back order right now. They will get a new shipload in 2 or 3 weeks.
But I found that Dale Penkala had one last pair left, so I jumped on them.  I'll get my binos within two weeks I believe (intl shipping), along with a Red Dot.
Thanks to all for helping me decide.

You have something to look forward to Lahoj.
I hope they arrive in prime condition etc. and wish you many happy hours looking through them.
