Advice for a newbie telescope builder please

Postby Richard Still » Fri Jan 29, 2021 1:37 pm

1) I'm building an 85mm ø refractor. I now have a reasonable image but want to add a star diagonal (1.25"). Approximately how much distance do I need to subtract from the draw tube and eyepiece to allow for the extra length once this is added? I'll experiment to get it right but need a starting point.
2) Can anyone recommend a suitable source of information for amateur builders of small telescopes please - either books or websites.
Any advice gratefully received, thank you.
