My new book is out, and selling. It’s a niche book about microscope filters called:
How to Make Rheinberg Filters, for the Hobbyist and Professional

Here’s my site that tells about it:
www.rheinberg-filters.info

One of my fans just posted this on www.tardigrade.us :

Hi Mike
I am very pleased with the book and it’s updates.I bought a set of your filters in Sept.08(we had a email exchange on Land Rover ownership[hand cranking!] as well as the filters) and they are still going strong.
I’ve made filters myself in the past,but decided to buy the E book to find out how to improve my manufacturing technique.I’ve found it most helpful,thank you

Best wishes for the future
Tony

Well, here’s a picture from my Land Rover days:
