Our Annual Meeting

The date for our next Annual Meeting is set for the 17 June 2023 at the Institute of Astronomy in Cambridge. We have all the details sorted out now.

We hope to see you there for another interesting programme and a chance to talk about deep-sky astronomy, amongst other things.

Our Publications

The Webb Deep-Sky Society has a wide range of publications on offer.

You can grab a free PDF copies of Faith Jordan's 'An Introduction to Deep-Sky Observing' and Miles Paul's Atlas of Galaxy Trios from amongst our free publications.

With kind permission of Kent Wallace, we can now offer our own reprint of his titanic work Visual Observations of Planetary Nebulae. Kent sold out of his own print run some time ago, so don't wait too long.

Mike Swan's excellent Atlas of Open Star Clusters is now available as a single spiral-bound volume. This has a few additions over his earlier volumes 1 and 2, which as still available.

Owen has a new book out based on his long running Galaxy of the Month column. He's added new information and updated his older work. It also contains detailed finder charts.

Issue 191 of The Deep-Sky Observer (DSO) is now available.

Why not join us?

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.

Perhaps you'd like to join our groups.io mailing group? Access is limited to members, but you're all welcome.

A small and fascinating piece of the huge dust cloud near Antares this month. Sandwiched between two huge reflection nebulae this image contains reflection, emission and dark dusty clouds.

Galaxy of the Month: Arp 232 in Leo

Owen has moved slightly to Leo for an easier target for those bright summer skies. There's a bit of cataloguing confusion to be had. But may be these galaxies might be more challenging than he thought.

Nebula and Cluster of the Month: Messiers 4 and 80

Patrick is back in the northern hemisphere this month, barely. He has a pair of globular clusters that are going to be a challenge for some, and that could be considered opposites of their kind.

Double Stars of the Month: STF 1850 and SHJ 263

A trio of doubles that shouldn't provide too much trouble for most from Bob this May. The last of his southerly pairings conceals a few additional challenges for those with slightly larger scopes.

Object of the Season: Planetary Nebula M 57 in Lyra

Wolfgang Steinicke would appreciate your observations of M 57 in Lyra for his Object of the Season column in the Deep-Sky Observer.

The Deep-Sky Observer

The cover of The Deep-Sky Observer 184

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
