Advice for tethered shooting

Hi, we are setting up a new documentation station at work and I am currently looking into different options for doing photo documentation. Maximum image quality is not of concern (unfortunately) but ease of use. Ideally it should be some form of tethered shooting to PC with a rather robust camera. T...

You have a full set of Phase objectives - Do you have the phase condenser (U-PCD)? it can be used with immersion medium and then - iirc - with condenser na of 1.25.

@enricosavazzi
thank you for sharing this experience. i think that accuracy is key here. I agree, the price (incl s&h and import duties) is prettey steep for what you get.

There is this guy on ebay selling a variety of condenser inserts in different sizes. I was contemplating of buying a set because i am also looking for an darkfield insert for the UCD8 but have never gotten around to.

I also would be interested in the PCB (2 if possible). I would like to adapt one to micro-manager via their arduino device adapter.

Hi Michael,

once again a wonderful abstract and colorful motif. I once read that ram is repetetive and boring but your images prove the contrary.

Hi Zed,

these are both great images. Thank you for sharing! I like the first one better - the steel grey of the eye complements the metallic blue better than the uv fluorescent light blue. The shadow doesnt bother me at all.

Kind regards

You can also use (clear) nail varnish. However, it does not look as fancy as ringing cement.
