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.
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 really was going to bring you an amateur image this month, but I couldn't get permission in time. The professional substitute isn't bad though, and I've stuck with star formation and clouds of dust.
A tight group of galaxies that will provide a test for observers using a range of telescope apertures from Owen. The bright skies are arriving for northern astronomers, so have a go while you can.
Patrick's struggling for objects again, but he's broken his own rules for this unusual open cluster. Accessible to small telescopes, it's well worth closer study, and more aperture if you have it.
Bob has a bright and even double for small telescopes in Boötes this month, whilst his choice in Virgo is distinctly unequal. There's a serious challenge for large telescopes too.
Wolfgang Steinicke would appreciate your observations of the NGC 4038 and NGC 4039 galaxy pair in Corvus 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.
