FYI only; I'm not the seller:
Garrett 150/45 w/tons of stuff

I'm guessing that a motivated individual could sell all of the included eyepieces and barrows for ~$750.

Yep! And there's a "Make Offer" option, but he says he won't come down on the price.

I'm not the seller, either. But I think it's a good deal on a true monster pair of binos, with a sick EP collection.

Looked through these at 2010 Okie-Tex SP.

Unimpressed with optics and appeared to have the usual vignetting problems... ie effective aperture envy.

:p

I don't recall having heard much of anything about the 150mm BTs since they made their debut in 2009 in this thread:

My own experience on 25x150mm UO Binos

Did I miss any reviews?

Just wanted to get confirmation you are talking about the 45 deg version. I thought the effective aperture issues were with the 90 deg version? :question:

45 degree version.

Obviously, couldn't measure effective aperture using flashlight method as these were in the field.

Looked at edge of field illumination from objective end.

Noticed the bidding stopped. Were they ever sold. I may have been interested, since they are alot cheaper than new.

Concerned about colimation, since he mentions just being returned from being fixed. Why would they go out of colimation in the first place, and would this re-ocurr?

It's listed again.

With the design of these 150s, the collimation is likely made by tilting the Porro II prism mounting plates in the rotating turrets. It the turrets have some mechanical slop in them, I could see how collimation may be affected. Also, this method of "collimation" can easily amount to just conditional alignment if the right equipment and technique isn't used.

I'd question why a "A new, replacement, Helical Focus Assembly" is included. Who's been working on this bino?

Was it 1.25" eyepieces only or 2" also?
Is this the same as the new Garrett 150/45, or is it an older model?
Would helical focus assembly be an upgrade, or a fix (to the previously mentioned colimation issue)?

Bill,
From earlier readings about the 45 degree version of these 6-inchers, I recall them as working at very near to full aperture. Your checking of vignetting when looking down the front end must be interpreted carefully, and done with an eyepiece in place, at focus. For one thing, you must completely disregard what's happening at the edge of the circle of light produced by the eyepiece; this means absolutely nothing as regards on-axis utilization of the objective aperture. Instead, you center some identifiable feature in the de-magnified image produced by the eyepiece. Then you find the point where that centered feature becomes clipped by an internal restrictor, checking where your sight line at that point intercepts the objective.

With most any commercial bino, if you use clipping of the *outer* part of the eyepiece-formed image, it will give an indication of useable aoerture which is artificially reduced. And for those using interchangeable eyepieces, the wider field types will give a poorer (but false) impression than will the narrow field types.

He cancelled my highest bid at 3:45AM while I was sleeping, since I have have hardly bought anything on Fleabay before.

I remember talking to Marcus at APM an also Garrett and they did upgrade the prisms to larger ones to prevent any vignetting. The 90 deg's still had some vignetting issues but the clear aperture of the 45's were excellent full open views with 22 Naglers and even 21 Ethos. Id Imagine they would be spectacular with the 100 deg 25 ES if those weren't too wide.
Garrett sells some nice SuperWide Angle 26mm 71°, 32mm 72°, & 38mm 69°, 2.0" FMC Eyepieces.

Those have got to be unreal when you have that flexibility in interchangeable eyepieces like that!

Consider what happens to aberrations at f/5.5 when arbitrarily chosen eyepieces , about which the designer could only guess when balancing the system, are added to the prisms and objectives.

Perhaps this suboptimal compromise is justified by the possibility of varying the system magnification?

I have tried eyepiece switching on the F/5 Fuji 25 x 150, with less than super results.

Substitutions are worse on the F/ 3.5 WW II 10 x 80 Flak 45 deg inclined Busch design, in general, though Nagler Ploessls were acceptable over their fields, which are much narrower than the 70 deg or more originals.
