Re: My New Poor Man's Stereo Microscope Setup

Hi Don - in no way trivial! In the spirit of adventure and exploration that we all share here! I myself started-off with an old mobile 'phone that amazingly for the time, 'took pictures' - of about 100K... It was enough for me to take images of wild flowers then peruse them, on said tiny 'phone's sc...

Hi all, clearing the lab of some room I have just listed - you know where - a complete phototube assembly including projection-eyepiece for an Olympus BX/IX infinity 'scope - all this needs is a C-mount camera attached (e.g. the ToupCam USB cameras or the 'industrial HDMI cameras) to take photos and...

Re: Choosing Camera

Thanks garstro - that video (both in fact) looks crystal-clear to me. Did you have the reduction lens in and what resolution/format are these recorded in originally, before YT's adjustments?

Does this record to the TF vcard or does it record to a laptop via USB?
Thanks for posting.

Re: Choosing Camera

Well, for simplicity and quality at reasonable levels I'd say a 'Toupcam' USB-2 to start you off. This would really only do well for stills though as they are quite slow when shooting video... For stills and/or video I'd go for a used Canon, perhaps an 1100D or 1200D depending on price, with a std D...

This is the type of holder that you'll need.

The above is for thin microtomy of fully processed tissue, such as those ulti...

Maybe this is a dumb question, but did you do the initial setup of eyepieces for parfocality? It might help anyway. Wilds are definitely excellent. Definitely not a dumb question, I've lost count of how many times I've overlooked the basic or even the downright obvious during microscopy, from day o...

Yes, they do seem to have a consistently excellent reputation. I must however have the ability to use both eyepieces AND the camera simultaneously, preferably switchable too. Does yours have this capability?
