One thing to consider is that many Newtonians [Dobs] do not have enough back focus to allow the mounting of a camera, if the owner
decides to give some photography a go. Skywatcher Newts do have
enough back focus, and part of the focuser screws directly onto
the appropriate camera T-ring.
My 10" Skywatcher collapsible holds collimation as well as my 8"
solid tube Newt. Extending the tube takes about 15 seconds, which
is not exactly a chore, and the 5 yr warranty sealed the deal for me.
