Machined threads for telescopes explained

Unread post by Pete » Thu Sep 20, 2018 12:26 pm

Just stumbled upon this super guide to what thread size is used for different filters, etc. https://agenaastro.com/astronomy-threads-explained.html

Don't know any astronomy hobbyist who hasn't bumped into thread incompatibility problems explained in this great article.

Pete this is not the first time I have come across this piece of information.As you mentioned and as I have found out,Can be very useful for matching equipment up. In most cases it can be after the fact that a buyer finds out that things don't fit. :o :o

Agreed Pete. Manish has a great site. Very informative.

When I buy astro-gear I look to his site 1st. Manish and I were Antares distributors when ClearVue Optics hung out its shingle. I recently bought my ZWO camera from him. It shipped priority mail and it was shipped that day. Highpoint, and OPT didn't have the camera I bought in stock. His website said "18 on hand". Great guy and stands behind his products. 8)

Thanks, Pete. Very useful reference.

Like Mark, I too have always had a great experience when dealing with Agena Astro. One time I ordered something and Manish somehow knew that I was ordering the wrong thing and contacted me helped me figure out a better solution!
