I've recently upgraded most of my eyepiece collection for my 8" SCT to ES and Meade 68's and 82's (also a couple of Hyperions). The 82-degree eyepieces and Hyperions naturally soften a bit in the outer 25% due to the normal spherical curvature of an SCT system. I'm contemplating adding a Celestron or Meade f/6.3 Reducer/Corrector to flatten the field and sharpen the edges a bit. However, since SWA and UWA eyepieces (particularly the 82's and Hyperions) tend to have edge softening and exhibit greater coma in faster scopes, will I gain anything?
Does an R/C improve edge performance even though the system is now f/6.3, or does the faster f/6.3 system essentially negate any improvement from the correction/field flattening the R/C provides? I am primarily a visual observer, so I'm not concerned with AP issues.
Thanks for any guidance you can provide.
