An international society of amateur and professional
astronomers specialising in the observation of double
stars and 'deep sky' objects founded in 1967.
Membership is open to anyone who shares the interests
of the Society.
Our Annual Meeting for 2025 was held on Saturday the 28th of June 2025 at the Institute of Astronomy in Cambridge. Thank you to all our helpers, speakers and those who attended and stuck with us in the heat.
So now the work of organising the 2026 Annual Meeting starts. We'll have a date for you as soon as possible, keep watching this space.
You can now join the Webb Deep-Sky Society online using PayPal. Options include Paper and PDF versions of the Deep-Sky Observer journal, or PDF alone for a reduced price.

A look inside the star-forming regions of the Perseus molecular cloud with an infrared space telescope this month. Yes, it's a professional image, but a rather unique perspective on a well known object.
Owen has a field full of galaxies that offer observing challenges for a range of telescope apertures. They can all be squeezed into the same field of view, but how deep can you go?
Frequently overlooked, yet accessible to most telescopes, Partick invites you to take advantage of the dark and mild autumn nights to look at one of the many open clusters in Cassiopeia.
Bob's offering an attractive unequal northern pair which will be tricky for smaller telescopes, whilst his southern choice is less extreme, there's a much more challenging split nearby.

Wolfgang Steinicke would appreciate your observations of planetary nebula NGC 6543 in Draco for his Object of the Season column in the Deep-Sky Observer.
Profusely illustrated, The Deep-Sky Observer is printed on art paper. Its magazine format encourages all amateurs to make a contribution to the Society's work.
Double Star Section Circulars (DSSC) feature the latest techniques and measurements from double star observers around the World. They are available as PDFs for free download.
Some observations and images provided by amateur astronomers around the globe. We're happy to receive your images, sketches and observations of the deep-sky made in pursuit of your projects.
