Trevor, you are spot on, which is why I suggested the 127, which is a
Mak, and much more stable, even though it's on the same mount.
Anothernewbie, I had wrongly assumed that you preferred a motorised mount. Bintel and Andrews will be quite happy to help you on the phone.
There are several decent brands of 6" Newts on EQ mounts under $800,
including Skywatcher, and GSO. These can be fitted with a single axis motor drive fairly cheaply. Just be sure to ascertain from the vendor
that your choice of scope has sufficient back focus to enable it to
be used for prime focus photography, as many brands do not.
