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 wonderfully detailed SHO narrowband image of one of Stewart Sharpless' H-II regions. This one comes complete with a fugitive in its midst and a pile of astronomical designations.
Owen's starting the New Year with a pair of galaxies that will challenge UK observers. Those further south should find one of them easier and than other, but there's a real challenge for large scopes.
Patrick starts 2026 with a historic and unusual open clusters surrounded by nebulosity. The cluster is easily seen in modest telescopes, the nebula will be much more challenging.
Bob offers a wide binary system some distance from the Hyades, of which it's a member, and a much closer, very uneven, pairing with a touch of colour. Both are available in modest telescopes.

Wolfgang Steinicke would appreciate your observations of the galaxy Pair NGC 4567/68 in Virgo 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.
