2 inch Diagonals and Focusser Travel


Recommended Posts


If anyone has made the switch from 1.25 to 2 inch diagonals recently - do the 2 inch ones need more inward focusser travel than the 1.25's ?.

I'm thinking of using a standard (ie: not dielectric) 2 inch Antares mirror diagonal in my refractors but some of my eyepieces already require some more inward focusser movement and I'm worried that I might run out with a 2 inch diagonal. I've currently got about 1 inch inward travel to spare with the most demanding eyepiece in this respect.
