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’.

I would like to dedicate this website to Rod Mollise whose posts in ‘Uncle Rod’s Astro Blog’ have, for many years, been a source of great inspiration for me.
Ian Morison FRAS is an astronomer and astrophysicist who served as the 35th Gresham Professor of Astronomy. Though a radio astronomer by profession, now in his 54th year at the Jodrell Bank Observatory of the University of Manchester, he has been a keen amateur optical astronomer since making his first simple telescope with lenses given to him by his optician when 11 or 12. In 1990 he helped found the Macclesfield Astronomy Society of which he is now patron and he is a past president of the UK’s Society for Popular Astronomy, now acting as its Instrument and Imaging Advisor. He writes a regular ‘Telescope Topics’ column for ‘Popular Astronomy’ and has made many contributions to the ‘Sky at Night’ and ‘Astronomy Now’ magazines.
His recent books published by Cambridge University Press are shown below and all can be purchased from Blackwell’s, just search for ‘Ian Morison’.
A book aimed to bridge the gap between books for beginners and the specialised books about individual practical astronomy topics.

[The opening image is of the galaxy M33 in Triangulum. It was taken remotely using an ASA 8-inch Newtonian Astrograph located in Spain. The data acquisition and image processing used to achieve this image are described both in ‘An Amateurs Guide…’ and ‘The Art of Astrophotography’.]
