SHELF II · TELESCOPE
“The telescope came out twice, showed me a blur, and now it lives in the hall cupboard.”
Choosing and Setting Up Your First Telescope
Refractors, reflectors and catadioptrics compared honestly, mounts that do and do not wobble, aligning the finder in daylight, collimation, cooling, and the eyepieces that are worth buying first.

Questions about this course
What do I need before I start?
A telescope. Nothing has to be bought in advance: the course opens with what to choose and why.
How long will it take me?
There are 40 lessons, 8 h of video in all. At about 3 hours a week that is roughly 3 weeks, but the pace is yours: clear nights decide more than the calendar.
How long can I watch it, and is there a tutor?
You can stream every lesson for 18 months from when access starts. The lessons are recorded: there is no live tutor and no marking, and the videos cannot be downloaded.
