Focuser for 4" newt mounting holes
Need some help guys.
What would be mounting holes apart for 4" newton telescope?
Older scope has 0.96" focuser, so if I want to get 1.25" focuser would it be needed to drill new holes. Old one has 49mm holes apart.
If you can measure on your 4" newtonian, will be much appreciated.
Many thanks, cheers.
