Hello

I just received a slide with diatoms from Oamaru.
An Auliscus i think.

170 shots taken with an Olympus BH2 + DApo 40/1,3 + NFK 2,5 + Canon EOS 500D - Stack with Zerene Stacker.

Nicely done. You are using a really fine objective, and this makes such a difference with a subject like this. I'm interested to know how you used up 170 shots on such a relatively thin subject. Were you advancing the fine focus by hand or do you have a fine focus system driven by a stepper motor?

Hello

Thanks for your message.
I move the microfocus knob with my hand.
On BH2, one step corresponds to 2 microns, I can make four to five photos between two notches.
