1.25" or 2" diagonal?

I have a Celestron 9.25 SCT and am thinking about buying a binoviewer. I currently have a Tele Vue 1.25" Everbrite diagonal. I plan on using 16mm Tele Vue Nagler type 5's. (I already own one) Will the 1.25" diagonal be sufficient or is it a must to have a 2" diagonal? Vince

Hi Vince,

I use a 1.25" in my 9.25 with no problem in regards to focus but I'm not sure about the Nagler issue though.

Clear Skies,

Steve
