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 got a wonderful amateur image of an elusive large supernova remnant that's high in the night sky this month. This is certainly one for the imagers out there, or radio astronomers of course.
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.
This month Patrick brings you an planetary nebula that's held a fascination for him for over 40 years. He urges you to seek out detail in this object with whatever telescope you have to hand, you may be surprised.
Two more star pairings that are easily accessible to modest telescopes from Bob this August. There's some hidden complexity to the first and colour in his second selection.

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.
