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.
The Webb Deep-Sky Society has a wide range of publications on offer.
Please note that due to a change in customs documentation requirements we regret that we cannot offer delivery to European destinations outside the UK after 31st October 2026. We hope that we will be able to resume once we've had time to fully understand the implications of these new requirements.
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 a favourite and familiar view in either binoculars or a telescope this month, but with a twist due to David's use of a little narrowband data. This pair of clusters are as amazing as they appear.
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.
A rich open cluster in one of my favourite constellations. This one's accessible to most instruments too, but not the naked eye. Patrick explains why it's worth your time to seek out this Autumn.
Bob brings you a bright binary in Pisces that's suitable for small telescopes and a more challenging uneven pairing in Cetus for nights of fine seeing.
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.
