I bought one of these
https://www.amazon.co.uk/Erecting-Te.../dp/B00AZKNIWW
mainly because I wanted to also use my Ed 72mm as a birding scope, but as I have found out it will not work with either scope (in the images)
Is it just me, can not focus over 50', appears not enough inward travel on focusser and I am not going to start cutting my tube down
Thanks
