par focal distance / tube length

#1 Post by sombre » Thu May 30, 2019 2:17 pm

Hi everyone,
My microscope is an Olympus bh2/bhs.
My question is, how do I work out the amount of extension required when
I attach my Nikon D7200 in order to maintain the 160mm par focal distance.
ie:- between which two points do I take a measurement.
Hope this makes sense, as you can probably tell i'm new to all this.
Many thanks in anticipation of someone switching the light on to my query.

This should help answer most of your questions:

These are links to some articles that Charles Krebs has kindly written to help people set up their cameras.

If you have not seen Charles Krebs' photographs you are in for a treat.
Last link is to his website.
There are additional articles on there.
