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 fabulously detailed image of an interesting object that's high in northern skies at the moment. This emission nebula hides stars from both ends of the extended Morgan–Keenan scale.
Owen's chosen a rather bright galaxy on the doorstep of on of this seasons showpieces. In bright summer skies it's hard to see much else, but he's posed a challenge for those that are up for it.
Patrick's back on track with the Milky Way moving into prime observing position, and he's picked a showpiece planetary for those with a medium aperture and perhaps an OIII filter.
Two double stars that are well separated and excellent targets for smaller telescopes from Bob this July. These fields are rich in doubles, but there's a particular tricky challenge near his southern choice.

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.
