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.

Our Publications

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

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.

Owen has added a Volume 2 to his Galaxy of the Month book series. We have a special price for those that choose to buy both volumes.

Issue 194 of The Deep-Sky Observer (DSO) is now available.

Picture of the Month: ESO 217-25 in Centaurus

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.

Galaxy of the Month: NGC 5223 in Canes Venatici

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.

Nebula or Cluster of the Month: NGC 5466 in Boötes

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.

Double Stars of the Month: STF 1825 and HJ 4651

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.

Object of the Season: NGC 4038 and NGC 4039
