During my last trip in the US, I was able to pick a 114mm/25.4mm primary/secondary mirror pair for 18$ (Telescope warehouse on eBay). After a lot of back and forth, I decided to make a travel telescope out of it.
A travel scope is a telescope that is designed to be pulled apart and reassembled relatively rapidly and that can therefore be used for trips (as its name indicates).
This article explains the design that I used what I learned and the things that I learned during the process. Hopefully, it can serve as a warning to others!
The total cost for the scope (I had wood and nuts available to me), was around $40! Not bad!
See this 7-page PDF for a more complete description of how to build this scope,
illustrated with 17 photos (6 of which are shown below).
