Advice on buying simple telescope

From my own experience, I would advise you to get the best you can afford. A cheap one would be false economy.

I went to a camera specialist, Jessops, to buy ours. I think you’d be disappointed with a child’s version. The shop had the technical knowledge and advised what was suitable for our needs. We bought a sturdy tripod separately.
Our GCs use it with ease. I’d tell you the make, but it’s at our 2nd house.
