60 mm refractor on a light mountReviewed, not suggested by the advisor
Bresser Skylux 60/700 AZ
The listing at Lidl gives a “maximum useful magnification” of 525× — on 60 mm, an exit pupil of 0.11 mm. The usual rule — twice the aperture in millimetres, an exit pupil of 0.5 mm — gives 120×.
Before you buy it: what the advisor suggests for a similar price
Chosen by a rule, not by hand: catalogue models at 1.2 times its price or less (€118 at most, for €99), with at least 60 mm of aperture, in families the advisor scores at least 3 out of 5 for the Moon and the planets, in the order it ranks them at that budget — two models per family, three families at most. The advisor never suggests the model on this page. Everything else is the questionnaire's default: a first instrument, a garden, carried out by hand, a suburban sky.
No model in a family scored 3 out of 5 or more costs €118 or less today.

70 mm against 60 mm: 1.4 times the light, and doubles split down to 1.66″ against 1.93″ (arithmetic); €20 more.
Every price is the one the model's own page leads with, and that is the price the rule compares with the threshold. Whether a shop pays us plays no part.

The same Saturn, at both powers
Computed, not photographed: the same renderer as everywhere on this site, which darkens and blurs the view as the exit pupil shrinks. A suburban sky, a steady night.
