Can anyone relate how well the "visual" image quality of the C6 is improved by the Celestron Focal-Reducer / Field Flattener, PN 94175 ? This is the "standard" 0.63x unit that converts F/10 to F/6.3.
Years back I had the C6 and liked it a lot except for the field curvature that my older eyes can not accomodate. That is, when I had sharp focus in the center, the outer 1/3 of the FOV was out of focus. And likewise when focusing the outer 1/3, the center of FOV was no good.
Thing is, does the FR/FF allow for sharp focus across the entire FOV? Or, is the focusing -still- compromised somewhat?
I have this scope & FR/FF on order and wanted to get some opinions on what I can expect.
Thank You and Clear Skies!
