Re: Infinity spaces in Wild M5?

Yes, looking at some more photos, this appears to certainly be the case.
You should be able to get a camera image just pointing down the infinity
tube with something like a 7.5 degree FOV lens (e.g., 125mm on a APS-C
format digital SLR). Which you can do directly with the binoc removed (not
very convenient) or via a beamsplitter.

Assuming that the optics aren't infinity -- what would I need to do to
get the right lens system for imaging?

Another proof of infinity optics is if removing the binocular head and
sighting through it at a distant scene works as a low-power telescope
focused at infinity.

Which should work as a telescope -- the binocular head+eyepieces, or
the zoom telescopes+common objective?

The objective should project a real image of a distant scene that the
other end (zoom telescopes, less the binoc head) is pointed at, and
the binoc head + eyepeices should give me a virtual image (suitable
for forming a real image on my retina) of the same scene if I point
the bottom of the binoc head at it. Is this all correct?

Anyhow, thanks so much for your help and advice!

I've got a question here, Wild made just about everything for this
instrument, for instance they made a switchable monocular camera
adapter for the M5. Why not start with one of these? The adapter was
made for a Wild camera but it should work with a Diagnostics adapter.
An LED is so easy to put just about any were there should be no
problem. Oh, it would be better to use a microscope camera, maybe one
with some real time capability, depending on what you do.

If the optics are parallel, you have a Galilean instrument, if not you
have a non-Galilean instrument. Most non-Galilean instruments can't
had a bunch of accessories on them, but their real cheap. Galilean
instruments can have one of everything on them but they cost big
bucks, their also easier to use for long time periods.

Now, all stereos really have a problem in measurement. Projected
lengths are really a difficulty when using a stereo. Take a look at
the new Nikon, the AZ100 (/www.nikoninstruments.com/az100/), its
monocular and telecentric, its perfect for measurement.

Sounds like your having fun!

Thanks,
