On my CPC925, more in-focus is required. I cannot use the FR with my binoviewers, for example. I also find that there is some CA at high magnifications. Of course it's primary visual purpose is not for high power viewing.

Using my Denk II binoviewer with dual arm Power X Switch in focal reducer StarSweeper mode is no problem in my C9.25.
