Re: AO Spencer Model 28LF, Yet Another Stereo

That is really sweet Kurt! We need a family portrait. :-)

I envy you. Somewhere I read of someone buying nice used scopes in that price range and giving them to his grandkids. Seems an excellent idea rather than giving plastic junk.

Congratulations

Re: Monocular vs Binocular/Trinocular imaging question

If you imaged through a monocular scope, wouldn't you get a higher percentage of light (100%) over a trinocular tube or even one ocular of a binocular scope (w/o trinoc) that would be 50%, or is the convenience of a trinoc worth the trade? Also good for share viewing, right? Although Oliver answere...

Re: Zeiss Standard gets a new home

At the moment we are trying to center the filament directly under the objective. Once that is done the next step is to use a slide to focus the filament at the Front Focal Plane. Moving on to that step, I find that I can only see the field diaphragm shadow distinctly when the condenser is racked to...

Re: Zeiss Standard gets a new home

The reason the filament moves in an ellipse as you rotate it rather than around its own axis is because it is not centered. I was hoping I would finally make my dilemma clear. I was also hoping it was an easy fix. I feared bent stuff. Thanks Glen. Now I should be able to get that Kohler thing down!...

You got me to revisit the illuminator setup Glen. I forgot that I got stuck and never finished that.

I would take a pair of eyepieces. If you can't get it to power, because of no cord, two alligator clips to a computer cord will do it.
