Paul, just do the sums. I just tried it with my 10", 254mm @ 1140 mm long dob f4.5 & a 6" 150mm @ 1000mm long ,f6.6. & 17.5" 445mm @ 2000mm, f4.5 truss dob. Naturally the AFOV will change.
Mine with a 32mm E/Pc, 52deg field gives me 36x mag@ 1.44 degrees AFOV.
6" with the 32mm E/Pc, 52deg field gives 31x mag @ 1.67 degrees AFOV.
17.5" with the 32mm E/Pc, 52deg field gives 62x mag @ .83 degrees AFOV.
Not exactly sure of prob. L.
