David, I am more a refractor user, however, I recall reading a number of comments on this forum that RC scopes are not considered highly for visual use. These comments have been driven by the RC design having a quite large secondary mirror in relation to the main mirror. This results in a central obstruction in the 40-50% range. Such a large obstruction adversely impacts the visual image, such as lowered contrast. Such a large obstruction is immaterial for astro photography.
Perhaps someone with actual visual experience using an RC can chime in on this.
Cheers
Steve.
