Apart from optical performance, portability may also be a factor in decision-making.
I separately bought a C11 & neq6 new for less than Au$3800 total.
I reckon that this combination is pretty much my upper limit, physically, in terms of being portable/transportable.
The basic set-up comprises 4 components (stored in a shed) which I assemble before use: the tripod, the mount head, counter weights & OTA.
An obs/pier set-up would be fab, but not all off us can go there <sob!>
If aperture fever might sway your mind, there's always this bloke to show you (in 2 parts) how *real* men feel about optical weaponry bigger than a C11 (!)
