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.
We held our 2026 Annual Meeting on Saturday the 20th of June 2026 at the Institute of Astronomy in Cambridge.
It's all done for another year, and the planning for 2027 can begin. Thank you to all our speakers and everyone who turned up, we hope you enjoyed yourselves.
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.

I have a fabulously detailed close-up of the outer structure of this month's planetary nebula. Whilst this is an infrared view, this nebula is great target for amateur imagers and visual observers too.
Owen's left us with a group of galaxies that might be available to more modest telescopes, try it and see. For those with monsterous aperture, or EAA observers, he's also provided a serious challenge nearby.

Patrick suggests that this is the perfect time of year to observe one of the essential objects in the life of an amateur astronomer. It is a tricky object but he has one important tip that makes all the difference.
This month Bob has a couple of bright and close doubles for you to observe. Those to the north have changed little in two hundred years, whilst those to the south are hurtling around each other.
Wolfgang Steinicke would appreciate your observations of the bipolar planetary nebula M76 in Perseus 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.
