I just finished building my first Galileoscope!
This is an excellent little kit telescope developed during the International Year of Astronomy 2009, and it’s intended to be used as an educational resource.
You can put it together and take it apart as often as you like – you don’t need glue to assemble it – and in its half-constructed form it can be used as an optical bench to test the optics.
I haven’t observed with it yet, but by all accounts it’s very good. Especially given that the objective lens is made of glass rather than plastic, which reduces aberation, and the eyepiece lens system is composed of two plastic acromatic doublets.
I’ll take it out next time it’s clear and have a look at the Moon and whatever else is up!
