Any real benefits from having the Meade ACF and very the regular SC for visual?

 

The abbreviation suggest it is coma free, but is coma really visible for 6" scope at f10?

 

TIA

I have had a standard 8" SCT, an 8" Meade ACF, and an 8" EdgeHD.

 

I definitely notice coma in the standard SCT, particularly with a wide field eyepiece.  I find the views in both the ACF and the EdgeHD to be much better towards the edges of the field of view.

 

Note that this is a bit of a personal thing.  Some people are bothered by coma, and some don't notice it.
