12.5mm--16'
14mm--24'
17.5mm--not measured
10' is considered essentially perfect, and seen as a tiny dot.
These measurements are at the edge of the field, where you generally aren't inspecting star clusters or double stars.
At f/10, they are all essentially perfect.
I notice at f/5.75, the 14 is nearly perfect at the edge, so if that is the worst of them, this is a killer line.

My dream set is the Morpheus 17.5 and the 9mm with the APM 30mm UFF as I'm a dob user and there is next to nothing in weight difference.

I have the 17.5mm Morpheus. Just ordered the 9mm yesterday and the APM30 UFF is out of stock for a few weeks but plan to get that one as well and I think that's enough. I also got a Svbony 8-24 zoom which arrived today. Its cheap but it seems really well made. It reviews well on CN.
I am also wondering if I should upgrade my 9mm Nagler from a type 1 to a type 6. The T1 is quite sharp but advancements in the T6 may be worth it.
I think I'll wait to see how good the 9mm Morpheus is.
I also am interested in the APM 12.5mm Hi FW as it appears to be a clone of the Docter 12.5 which seems to be a legendary eyepiece.
Greg.
