What focal length did you buy? I think most are buying the 4mm. I am curious to how the 8mm works, especially through a telescope.

To steal ideas from one person is plagiarism. To steal from many is research.

a cold copper/selenium bath or a hot caustic bath should do the job
When God said “Let there be light” he surely must have meant perfectly coherent light.

I use this http://www.micromark.com/Blacken-It-4-fl-oz,7267.html
It works good but if the part has threads you don't want to soak it. I use a Q-tip soaked in the solution to apply to the inside of threaded housings.
