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, dsr |

I’m running a Hensoldt 6-24x72 on my 30-378 Improved. To put it simply; WOW. I hog & coyote hunt at night, and to improve on this you’d need NV on a completely overcast night. I don’t think NV will outclass this scope if there is ANY ambient light. |

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. |

I want one of those :)
or a copy :) But I think that style of scope would work well with the bench-rest shooters, especially ones with rail gun rests. |

There is nothing particularly different about the physics of a spotting scope compared to that of a riflescope. However, one of the reasons you see better through a spotter, than through a riflescope is exactly the thing you are trying to eliminate: short eyerelief. With the eye so close to the eyepiece, it occupies a much greater solid angle. Hence, other light does not enter the eye and your brain can get a lot more detail from the image. ILya

ILya, Thankyew! Your description is exactly correct, of course. The engineer in me loves it when you talk nasty! |

The Russians have those rubber eye pieces to occupy the space of the eye relief. Remember those ?

Koshkin, Thanks, I understand the solid angle (steradian), now that you point it out and never considered that I was somewhat comparing apples and oranges and ended up being too critical on the rifle scopes performances. I would like to rephrase the question about the general physics of spotting scopes (scopes that are in production), is possible to make an eyepiece with long eye relief that contains a reticle? If it is possible would the reticle be first or second plane focused. I understand that without details it might be impossible to say if it is possible and your explanation in the previous post points out the disadvantages of such a setup. Now I am just curious. Thanks, dsr |

Magnumdood,
That is the scope that that I am considering for my target rifle (hoping to get a small advantage on over cast days). It is the most impressive scope that I have been able to look through (two short test viewing sessions) and it is reassuring to hear the scope lives up to its reputation. Just one question, are you using any type of muzzle break?
Good hunting, dsr |

One of my early posts at this site showed the difference in ability to read the words "THIS SIDE OUT" on my pump house 127 yards away from the porch. Just in case you missed it I'll give the condenced version. I compared my Minox 13X56, 4 1/2-30X50, and 12-42X56 NightForce with all set on 13X. I was comparing them after sunset. When I could no longer read the words, but had to try to make out letters, I called the time. Minox quit at 6:42. Bushnell quit at 6:44 and the NighghtForce quit at 7PM! When I turned the power ring on the Bushnell up to 18X I could read the words again. During the day no one can tell any difference between the Busnell and the NightForce.
