Polarized Melatonin at 100x

Here is a picture of polarized Melatonin crystals. The image was taken at ISO 200 and 1/10 exposure. This was my first acceptable try at stacking.

Help with stacking in CombineZP

Has anyone used CombineZP for stacking? If so, I have some issues with regarding focus stacking. I was trying to focus stack a quartz photomicrograph with 15 frames. Each frame was focused in 4 degree intervals in my Olympus BH2. Each time I try to do the Macros to perform the stacking functions, ar...

I have bought an Olympus BH2-BHT Microscope a while back and found that the right focus knob is misaligned relative to the drive shaft. This leads to a crooked fine focus knob which may or may not function properly. Does anybody know if its possible to straighten the focus knob and align it back to ...

Thoughts on a reducing relay and a higher mag photoeyepiece

Hello, I am interested in using a higher magnification Olympus NFK 3.3 eyepiece and a reducing relay to mimic the image of a NFK 2.5 eyepiece or even a 1.67x. Does anybody have experience in doing such an optical setup where a higher mag photoeyepiece is coupled with a relay to increase F.O.V ? If s...

Re: Dovetail Condenser Adapter for Olympus BH2

The main thing that I am trying to look for is a dovetail mount that when attached can turn a circular mounted condenser into a compatible dovetail. The particular example I am looking for is seen in gekko's post where he modifies a condenser to fit into the mount.

Resale Value of a used BH2 Trinocular Microscope

Hello, I was wondering the potential resale value of a used Olympus BH2-BHT Trinocular Microscope with 5 objectives, 2 being an SPlan 40x 0.70 and SPlan 100x 1.25. The condenser is a fliptop 0.16-0.90NA condenser.
Kind regards, Microman2

Crystals

When I make crystals for observation I usually add the solute in a water/alcohol solution and let evaporation takes it course. My question is when crystals are made this way do I have to cover it with a coverslip to preserve it or can I leave it out in the air after evaporation is done?

My microscope is a no name without a field diaphragm or collector lens so Kohler is impossible? Would anyone inquire other methods of reducing uneven illumination when taking pictures? I was thinking of using a ground glass diffuser but I'm not sure about other approaches.
