Tabletop Dobsonian vs GoTo Telescope: Which First?
A tabletop Dobsonian puts almost all your money into aperture, which is what determines how much you actually see, and it is ready in seconds. A GoTo puts a large share into electronics and finds objects for you, with less aperture for the price. Buy the Dobsonian if you want the best view per dollar; buy GoTo if finding objects is the barrier that would stop you observing.

Frequently asked questions
What can I actually see with a 130mm telescope?
Lunar craters in detail, Jupiter's belts and moons, Saturn's rings, and the brighter nebulae and clusters. Galaxies appear as faint smudges rather than the coloured spirals in photographs, which is worth knowing before you buy.
Does a tabletop telescope need a table?
It needs something solid at roughly seated height. A sturdy stool or a purpose-made stand works; a wobbly camping table will spoil the view at high power.
Is aperture really the most important thing?
Aperture and how often you use the telescope, in that order, and the two trade against each other. The largest telescope you will actually carry outside beats a bigger one that stays in the cupboard.
How we choose: we compare published manufacturer specifications, optical figures we can verify, and reviews from owners who have used the equipment under real skies. We do not test gear in person. Never point any telescope, finder or binocular at the Sun without a certified full-aperture solar filter fitted over the front of the instrument.
