Hello Asher,
Here is an example of some experiments I did on HFD focus experiments as a "tutorial" for myself.
The tape measure was at HFD/2 and the red tip of the valve was at the HFD. This is one of a series of experiments testing the idead of focus at HFD (Kerr and Prevost) and focus at infinity (Merklinger).
And here is my polarisation experiment (the weather that day was really bad !)
Regards,
Jeremy.
