I am interested in buying a Wild stereoscope of the M5/M7/M8 series.

Could someone discuss the different versions of these lines of scopes?

I recently saw a listing for a pair of Wild M7A and Wild M7S
stereoscopes...what are the differences between these scopes? Are
there
more variations of this particular scope?

Also are there similar variations of the M5 and M8 scopes?

Finally is there a web page that discusses the stereoscopes that Wild
has produced over the years?

Thanks

The M7 has the exact same spacing as the M3 and M8. The M7S is
essentially the same as the M7A except that the objective lens group
is movable on the M7S. This allows the observer to use the scope in
either : 1) The standard configuration (left amd right optical path
displaced from the centerline of the objective group). 2) Left
optical path only (centerline of left optical path coincident with
centerline of objective lens group). This allows for a parallax free
view amd allows epi-illumination into deep holes.
There are other differences between the M3, M7 and M8:
1) The cam/ramp mechanism is different on all three scopes - this is
only of interest to a Tech.
2) The M8 objective is a Plan. This might be of interest to you if a
very flat field is required.
3) The M3 also came in a M3C variation with fixed lenses and only one
moving part. Magnification is in discreet steps. This may interest
you if you need a scope that can take a little rougher handling.
The M5 does indeed have a wider spacing of the optical paths.

Another question....do the same accessories like optional lenses fit
the M3/7/8 scopes?

I am assuming that the M5 accessories are unique to only that
scope...true?

Thanks

The M8 has a unique objective, the others are interchangeable.- Hide quoted text -

Thanks Victor...so the M8 uses its own specialized accessory optics
while the M7 and M5 can use the same accessory optics which are not
usable on the M8?

The reason why I ask is that I thought some ot the M8 accessories
(phototube) would work on the M7 and not on the M5.

TMT

TMT, The Wild M8 can use all ot the intermediate tube accessories
that are used on the M3 and M7 series. You expressed interest in a
phototube; that would work just fine. The only intermediate accessory
that would be prroblematic would be the vertical illuminator. The
illuminator has polarizers in the optical path and requires a 1/4 wave
plate to change linear polarized light to circular polarized light.
The wave plate holder attaches to the objective lens on the M3 and M7.
It will not attach to the M8 as the outside diameter is larger. None
of the accessories that mount on the end of the objective will work on
the M8. That being said, I can only think of one other accessory that
attaches to the lens (a small mirror for vertical illumination) other
than the aux. objective lenses (this is another consideration).
