Using an Alt-Az telescope mount as a motion control stage
Here is a short video demonstrating the use of an Alt-Az telescope mount as a 2-axis stage for closeup photography. https://bob-o-rama.smugmug.com/Infinity-Photo-Optical-K2-SC-Long-Distance-Microscope/i-Rj7q3Zw I had built this a few years ago but had to cannibalize it. The above is "first light" te...

Re: 1908 gold coin
Thats a nice fixture and it seems to work great. ( I have a very ugly version of that and it works pretty well, mirror salvaged from a dead digital projector. ) Where did you source the mirror?

Re: Corn kernel showing endosperm
Amaizeing! But really, nice imagery and something I had not seen in that sort of detail before. Interesting. Any idea what the different stains are targeting?

Re: Horse Ascaris egg mitosis
Those are the type of eggs you don't want in your egg salad. I think a lot of that grain is just just inherent in the staining, there is actually a lot of structure to cytoplasm. You have some very eggciting images from this and your other recent eggsplorations.

Re: 2nd try stacking with... Kalanchoe?
They are very nicely composed, and well executed. If this is your second attempt, you are doing pretty well, IMO.

Re: A micro riddle
That is gorgeous and the comb like structure is very much unexpected. I wonder if this is growing at a fast enough rate you could observe it with a time lapse.

Re: Bleb formation, amoeboid movement
So is this in response to a "food this way" sort of chemical signal? Or does branching just occur, and whatever ones are successful are reinforced?

Re: How to get bright white backgrounds?
( The suggestion about using collimated rear illumination is likely the best solution. ) It may also be possible to use chromakey to enable your masks to be selected more reliably. You could distinguish between the chromakey background and white-ish specular highlights from the coins edges. Also the...

Re: Mud Dauber Cache
Honestly I never really thought too much about what was inside those things. Very interesting and nicely photographed. I'm thinking they would also make for a great timelapse subject.

Re: Black Widow Spider
Are those individual eggs, or is that like a dozen egg sacks which warrant some sort of military response?
