I ran into a similar issue with missing exposures and things getting out of sync (move, wait, MUP, wait, raise front shutter curtain, wait, trigger strobes and close rear curtain, wait, move, and so on). I tried many things, some mentioned here and some others not. One very interesting issue is the ...

I use the Stackshot focus rail connected via USB to a MacBook Pro running Zerene stacking software. Zerene has the ability to directly control Stackshot. The Stackshot controller has an output to trigger your camera, you need a special cable which Congisys offers. This works well for my use; Nikon 1...

I was lucky, I already had the 70-200F2.8..so I only needed the 77mm to Mitsutoyo adapter ($20).

I have used a Nikon 70-200F2.8 @ 200mm as a tube lens for the Mitutoyo objectives with good results. I also have used the Raynox 150 reversed as a tube lens with good results. The Raynox requires a bunch of 42mm screw tubes and a few adapters, but overall not expensive. You can find lots of informat...

I like the diffuser, good idea!! I have been using large styrofoam cups and also light tents (actually two, one inside the other) trying to get uniform lighting. The tents work well with the 4 strobes in double diffused light boxes, but create a large setup. I have been using the Ikea LED lamps with...

I found that mounted the base plate on a sheet of styrofoam and/or thick cardboard helped. I have the aluminum base tilted at about 30 degrees from horizontal on some thick cardboard and held up at one end with a tripod sitting on cardboard. All this sits on a foam table top cover on a sturdy table ...

Neils, I went thru some of these issues shooting silicon chip images. Vibration can come from all sorts of places. I turn the AC off, pool pump off, TV sound off and don't walk around during exposures. Lately I have been using a tube lens setup with a reversed Raynox, this setup is very long and sub...

I picked up a extruded rail from Thor Labs, they sell them in different lengths. The rail bolts directly to the base. Thor sells plates that attach to the rail, I used one plate with Stack Shot attached to the plate and another plate where the subject positioners (two cheap focus rails) were attache...

Chris,

Santa Barber Instrument Group, SBIG, has astrophotography cameras that might be useful. I have an old one that utilized a Kodak image sensor. These cameras have thermal electric coolers to cool the sensor, which improves the noise.

Thanks for posting this, very nice setup! Do you have any issues with the LED lamps giving even illumination on the subject? And, how did you attach the LEDS to the ARCA mounts (these look like the Ikea LED lamps I have, that have a clamp on the opposite end)? I assume you drilled a hole in the moun...

Nice setup. A couple questions, please describe your positioning fixture, how does the 180 f2.8 work with the Mit objective, and do you get good illumination uniformity from your clever light tent? I used a 70-200 f2.8 with the Mit and then tried the reversed Raynox described by others (Rik) here. I...

I noticed on the setup daemonoropsis has, that a iris diaphragm is being utilized behind the objective lens (# 4 in the images). This is between the 200mm lens and objective. The setup is really well done. Does anyone know the source of the iris diaphragm and what adapters are needed to get to the s...
