Telescopes

For beginners, planets, deep sky, Dobsonian, refractors and reflectors.

How to align the secondary and primary mirror of a Newtonian, which tools to use, and the symptoms that tell you your reflector needs collimation.

What you actually lose observing from a city, what filters and target selection can compensate for, and what has no fix short of a darker sky.

What a GoTo mount actually does, what problem it solves, how much extra it costs, and when a beginner can skip it.

Why a good pair of binoculars is often a better first purchase than a cheap telescope, and when it makes sense to skip straight to a telescope.
