The imaging newts will generally have the mirrors and focuser configured that reaching focus with a DSLR is straight forward.

On the down side, they require more careful collimation and tend to lose it more easily due to the shorter f ratio and the fact the secondary and primary assemblies are rarely much better engineered than the standard scope, which can cause frustrations. Carbon fibre tubes can minimise tube movement and temp changes.
