What is the experience using the Sky-Watcher Skyhawk 1145P SynScan AZ GOTO telescope and can it be recommended for a new astronomer? Is it any good?
No, I would not recommend this telescope. It has several counts against it:
Small aperture: 150 mm aperture is a recommended minimum.
Short focal ratio: Good mainly for low power wide field views, not suitable for planets.
Most of the money goes into the computer, very little into the optics.
Instead, I recommend a manual telescope with a large enough aperture to give satisfying views of both planets and deep sky objects. For the same money you can get a larger and more solidly mounted Dobsonian like Skywatcher Dobsonian Telescopes - Dobsonian Telescopes by OVL.
I don't have much personal experience of the cheaper goto mounts but I would be suspicious of any goto mount under £300 (thats just the mount! telescope would be extra.) I would recommend spending more on optics and solid mount rather than motorised systems for that budget.
A brief look finds this telescope of similar design but better spec, and a fairly trusty mount.
