I'm not sure whether the Skywatcher Equinox 100 is available in Australia, or indeed how it compares with other scopes. It is more expensive than the normal Skywatcher 100ED. I have the Equinox 80 and it is a really beautiful piece of equipment with an excellent dual speed focuser. There's no hint of needing to replace it with a better focuser (as seems common with the 80 ED).

Maybe someone has one and can comment with some authority.
