The Sky-Watcher Heritage 150 Tabletop Dobsonian is the number 2 pick in this guide, listed at £315.00 with 4.4 out of 5 from 104 Amazon ratings. It is a 150 mm f/5 reflector with a 750 mm focal length, a collapsible tube that Sky-Watcher says keeps its collimation, a reflex finderscope and a 1.25-inch helical focuser, on a tabletop altazimuth mount with rubber feet.

The interesting part is what the listing's own numbers do next to each other. An exit pupil of 0.2 mm on a 150 mm aperture only adds up at 750x magnification — five times the aperture in millimetres, and the same figure as the focal length. The optical tube length is given as 150 mm, exactly the aperture figure, on a scope whose focal length is 750 mm. The ratings are lopsided too: 78 of the 104 are five stars, but seven are one star. Everything on this page comes from the Amazon listing, not from testing on our side.
