Not just you "dobbers" (your words, not mine
), I've wanted something like this for ages, something to let me turn the collimation adjusters on the primary while my eyeball is looking in the focusser.
Yes, ok, you SCT guys can stop smiling now...
I keep thinking about building something, maybe just 3 cables a-la slow motion controls on scopes without motors, but I haven't quite got there yet.
