This digest has two aims.  

The first is to cover in depth, without being too technical, advances in our knowledge, equipment and techniques that I hope will be of interest to all amateur astronomers.

The second is to add to the content of the books recently published by Cambridge University Press and so keep them up fully up to date.

The author also writes a guide to each month’s northern hemisphere night sky.  Just search for ‘Night Sky Jodrell’.
