Can the Celestron f/6.3 reducer-corrector (#94175) be used for visual observing... (can't get M-45 inside my field of view even with a lower power 40mm. EP.) * C8 scope.. thank you John M

I have found the 6.3 F/R very helpful in viewing large open clusters (e.g., M39). It may not quite squeeze M45 or M44 within the field of view of my 8" scope, even with a 40 mm eyepiece, but what a thrill to see all of both Perseus double clusters within the fov as I saw them yesterday (Wednesday) with the F/R.

Yes, I've found it handy visually, for example,
- To get double duty out of an Ultrawide eyepiece.
- To get a big exit pupil for use with the H-Beta filter.
That said, whenever I did the exercise of tracking down galaxies with and without the reducer (using eyepieces that gave roughly equal magnifications), I've always found it more difficult finding faint galaxies with the reducer attached.
