I teach astronomy at all levels all over the UK

It is still taught in all schools but at differeing levels

Usually as a part of the physics syllabus, but it is available as a
separate GCSE exam qualification through Edexcel (formally London
board). Details available at:

(it was an easy extra certificate for anyone keen on astronomy)

A quick glance at the modern syllabus suggests that it has become more
qualitative and all the spherical trig for rising setting and
coordinate transforms has been removed.
