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.
Our Annual Meeting for 2025 was held on Saturday the 28th of June 2025 at the Institute of Astronomy in Cambridge. Thank you to all our helpers, speakers and those who attended and stuck with us in the heat.
So now the work of organising the 2026 Annual Meeting starts. We'll have a date for you as soon as possible, keep watching this space.
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 found an image that's full of deep-sky objects across two of my favourite constellations. Emission nebulae, open clusters and a monster star creating patterns.
A faint and challenging pair of galaxies from Owen this month. There's plenty of confusion about which pair is which because there's another even fainter galaxy for the ambitious with large aperture.

Patrick's chosen a relatively bright and accessible planetary nebula in a frequently overlooked constellation for November. A testbed for stellar evolution, there's detail for those with enough aperture.
Bob has a faint and widely spaced northern double for you this month, whilst to the south he points out a couple of much closer and brighter pairings, albeit the second is rather uneven.

Wolfgang Steinicke would appreciate your observations of planetary nebula NGC 6543 in Draco 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.
