Giant scopes? (60mm obj and more) who's tried em?

Hello from Maine,

Oh the curiosity of a huge "exit eye pupil" has got me!

(To discover exit eye pupil : divide the objective lens by the power, for example 4x32 scope has an exit eye pupil of "8" which is great)

I recently saw 6-24x60 scope and I've seen ATN has some 80mm objective scopes, I'm curious if anyone has tried any of these giant scopes and liked them?

Of course a cheek riser is in order, I realize that.

I'd like to see a benchrest scope designed that uses a mirror inside and has a Z shape, kinda like this but up-side-down :



...so the ocular lens can be the same height as it would normally be on a scope with 40mm objective, but maybe the objective lens could be really big like 300mm with a variable zoom like from 2x to 40x - while a scope like that would be silly for lugging around in the woods I think it would appeal to the benchrest guys very much, not to mention the railgun guys.

I don't see any big innovations in riflescopes really ... They kinda still look the same as they did in 1950 from a distance ...

I have the idea that a manufacturer of both rifle scopes and spotting scopes would have an easy time modifying their spotting scope line to also make giant benchrest scopes - I ran my idea passed a Chinese manufacturer via e-mail (or maybe just a Chinese secretary?) and they didn't go for it :(

So have any of you guys tried any really big scopes?

Thanks,
Craig

Thanks for the warning and review Kickboxer, I keep reading that ATN is garbage - it seems like Ukraine is not renown for quality control these days ("Kiev" cameras are also said to be avoided)

But 6-18x65, I bet the scope @ 6X was very bright with it's "exit eye pupil" of more than 10 :)

We need more giant scopes :)

I agree it's no good to have the ocular lens higher than a 32mm objective scope would normally be - but with a mirror inside and a "Z shape" the ocular can be low while the objective is high.

Yes I'd like to see a marriage between telescope and rifle scope :)

Yeah it's a pipe dream :)

However, I'm learning what giant straight body scopes exists, like Zeiss and ATN, unfortunately they are expensive. It seems like 56mm and 60mm are the limit within affordable models (China) :)

Have fun!
Craig

Well said, I'm sure good small glass beats big cheap glass.

However there must be a point that crazy large exceeds even good glass, like a 400mm objective :) I'd like to try that!

Oh we'll never know :(

Anyway, happy shooting :)

Thought provoking ...

Still I wonder if they took a different approach like a reflector telescope uses if they could make a really big scope for benchrest shooters that trumps the little hunting scopes ... There simply must be more ways to skin the proverbial cat :)

So, what is your idea for a "benchrest only" scope?

I mean seriously look what happened to the great glass traditional film cameras POOF - worthless over night. Some of these companies like Nikon are well positioned to put out one of these.  I saw some chinese military photos where they had a monitor mounted on the rifle and the viewer on the helment.  Pretty sure we have something very hush hush too but if we dont we are way behind.

LOL I found my old post on accident from a Google search :)

I have a big Millet scope on a little 22lr rifle, I get a kick out of that. I still like the big scopes.

Did I ever post the link to the crazy rail guns ?

A crazy gun like that deserves a crazy optic :)

OK have fun!

Ok, since the subject has been broached (flights of fancy) how about a question for Koshkin.  Does the physics of spotting scopes allow the design of an eyepiece with long eye relief that would contain a fixed reticle (all scope adjustments would be external).  Of all the rifle scopes that I have looked through (ranging from Zeiss Victory to barging basement scopes) none are as good as a quality spotting scope (ie Leica or Zeiss Diascope).  The Zeiss Victory Diavari rifles scopes comes very close or is as good as a good quality spotting scope but I have never been able to have both together for side by side comparison.

Thanks,

The army has used this idea for their sniper night sights, but that's the only place I've seen it used. This is the AN/PVS-10:

I'm not sure how many folks would appreciate the weight of a spotting scope on top of their rifle.
