What focal length?

want to buy a new scope for imaging wide field narrow band from my orange zone home in Geelong.

Looking to find the optimal size/focal length to frame a good number of narrow band objects. Hopefully want to find a scope that has a focuser adaptable to mechanising rotation to make mosaics easier.

Budget is up to 4K. Hope to find a scope no slower than F5.5

Will be used with a KAF8300 chip.

Esprit's look OK, but hate the focus rotation method, cludgy and rough on the one example I've seen in the flesh, and not automatable.
