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.
A slight change to the date of our Annual Meeting for 2025 which we hope to hold on Saturday the 28th of June 2025 at the Institute of Astronomy in Cambridge.
Please note that this date is still provisional and subject to approval by the Institute of Astronomy. We'll add more details here as they become available.
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.
This April I bring you an object with many designations, all confusing to me. Nevertheless, this is detail packed image of a fabulous object from the southern skies.
A tricky trio of galaxies, even with a large telescope this April. Nearing the end of the galaxy observing season in the north, Owen's interested to know how many of this group it's possible to pick out.
Patrick is back with the story of his pursuit of this tricky star cluster. One of a notable group of globular clusters to see this spring, his journey is illustrated by his sketches, and there's a surprise at the end.
Bob has a couple of double stars that should be relatively easy for small telescopes. In the southern sky he's provided an additional pairing that should pose more of a challenge.
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.
