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've chosen another fabulous image of a well known planetary nebula, because they're fabulous. This is a visual target, as well as a fine one for those with cameras, but it's a challenge either way.
I've chosen a pair of galaxies from the archive for this month that are most suitable for large telescopes. Nonetheless, a modest 20cm (8in) of aperture might be enough to find them.
This month Patrick has ventured onto a list of new open clusters, the first entry on that list in fact. A large cluster in plain view awaiting those with large binoculars or a wide angle eyepiece.
Bob has something for smaller telescopes and a few challenges too this month. He has a colourful pairing in Aquarius and a bonus double in Lacerta to keep you all busy this autumn.
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.
