The amount of time needed for this, varies depending on the design of the telescope and the difference between temperatures inside to temperatures outside.
What netwolf has done to speed things up, is keeping his telescope near an open door, so it's already close to outside ambient.

I might have to enquire about the local star gazing community group and tag along to see for myself and then decide.

Definitely worth doing.
One question, Trung, where at your place in Melbourne will you be setting up your planned telescope? In a back yard, or on a balcony or patio?
