Thanks Blue - by the way, does the Mak Cass focus in a similar way to a refractor ? EG... 2 wheels either side of the focus tube for easy right or left handed people
Different scopes have different ways of focusing. The Celestron has a focus ring around the lens like a regular camera lens. The Meade ETX-90 has a small knob you turn on the back of the scope for focusing. That one is pretty awkward to focus and shoot at the same time.
