Subject: FOVs Celestron radial Guider..


Hi Milton, Some time ago you gave the range of distance in arc minutes from the centre of FOV for the CRG as 20- 35 arc minutes. I guess that`d be for your C8. (would things be remarkably different for my C9.25? This seems to place the FOV for a 0.3 Mogg reducer/extender outside this estimate (based on The Sky 6`s FOVI window). Would this work, having a FOV for the imaging camera larger than the guide cameras` or would the prism get in the way perhaps? I guess there`s only one way for me to check & I`ve found I need a Mogg 1.25-T yet! Mark.
