Had to think long and hard to come up with that title.  :-)) - Mark Dreyer, DMD



Yeah, but look at the photos.  Clear as a bell.  Splitting the buccal and lingual is a great idea,
very difficult to get both in focus at the same time - gary

I think the photos look really good, have you tried adding a drop of ethanol to the chamber and gently drying
it before taking the shot? It helps bring out the spectral highlights -  Bill

Thanks, Gary & Bill.  Bill, yes, these photos were taken after rinsing the canals with grain alcohol and
thoroughly drying - Mark

Mark, don't dry too much,  leave a bit of the alcohol there,  the pics will be better still - Bill

Neat pictures.  You are going to keep this up and I’m going to have to buy a new scope with a
beam splitter and a camera - Guy

Hello Mark. What scope do you have? - Stefan

Stefan, I use Globals 6 step scopes. - Mark

Hi Mark , Ok. That scope is my favorite. I had to decide between à zeiss pico and moeller- Wedel .
So, i'd like to Mount a slr or à videocam on it. Do you have xenon or the metalhalid lightsource?
I tend to the cheaper metalhalid. It has 5500K instead of 6000K at xenon. What do you think? - Stefan

Stefan, I think you will regret not getting the Xenon if you are into photos.
You can never have too much light shooting photos through a scope. - Mark

Hi Mark the chamber shots look amazing! What magnification were the pics taken at? - Abdul

Abdul, Thanks.  The nice thing about use of the dual iris is that it increases your depth of field such
that it is much easier to take photos at very high mag while staying in focus.  This was taken at either
the next to highest or highest mag on the scope-can't remember for sure -  Mark

Thanks Mark, another question though, I have tried the f-340 adapter and currently have a f-220 adapter
but wanted to see if yours was the same as mine and how it connects to your dslr, did you choose the 220
over the 340, if so why?  Please would it be possible to post some pics of your setup?  I have a zeiss
opmi pico, with mora, integ video and lateral output port - Abdul

Hi Abdul, I chose the F220 because that is the adaptor that is required for SLR cameras according to my
course notes from a recent photography course I took.  Here is a photo of my assistant Fabiola reinstalling
the shround on the scope arm after putting in some wires to the camera.  As you can see I have a Zeiss
co-observer tube on this scope as well as the Zeiss F220 adaptor - Mark



Hi Mark, Thanks for the photo! I have the following f=220 adapter I think mine maybe an older version,
I was wondering if you could tell me if the one I have has the same ends and if so what adapter ring you use
to connect the camera to the dovetail? - Abdul
