Re: Telescope

Usually I have nice things to say about the US Postal Service. But this sucks:
Your item has been processed through our facility in ISC NEW YORK NY(USPS) at 7:22 pm on December 12, 2017.

Have a look at Sam's Laser FAQ. Search for "Unrandomizing the Polarization of a Randomly Polarized HeNe Tube".

Re: Pictures of my setup

Re: Holography Book

Note to Ed:
The link to the "Creative Camera and Darkroom Techniques, Summer 1986" version of the document is broken. You need to change the link from "7SBPCCDT.PDF" to "7SBPCCDT.pdf".
