Welcome to the website of the Derby & District Astronomical Society (DDAS). We were founded in 1974 and are open to all with an interest in astronomy. We currently number around 50 members from all walks of life and whose knowledge of astronomy ranges from complete beginner to advanced. The society holds regular meetings on the first Friday of each month (except July and August) at 7:30 pm at the Friend's Meeting House on St. Helen's Street in Derby. This period stone building is owned by the Quakers Religious Society Of Friends, and is next door to BBC Radio Derby. Please note that we are not affiliated with the Quakers Religious Society Of Friends, but rent the meeting space from them. This venue may be found on Google Maps. Meetings usually involve an outside speaker, but members also give talks, and the society holds a quiz in January. We also hold 'Introduction to Astronomy' evenings at the Friends Meeting House on the third Friday of the month, and these are designed to cover the basics of astronomy. See below for more information or check out our meetings programme. We are a friendly and, despite our subject, 'down to earth' society. Meetings are a great way for potential new members to see what we're about in an informal and relaxed atmosphere. The social aspect continues after most monthly meetings with a visit to, appropriately enough, The Seven Stars.
The society's Flamsteed Observatory houses a 10-inch Meade Schmidt-Cassegrain telescope and Altair ED-80 refractor on a computerised 'GOTO' mount. The observatory is named in honour of England's first Astronomer Royal, the Reverend John Flamsteed (1646-1719), who was born in Derbyshire and attended Derby School. Regular monthly observing sessions are held (weather permitting) at the facility and new people are always welcome. They are usually held on the second Saturday of the month and start times vary with the season. The observatory is located on North Lane, Ashbourne, DE6 1PL, about two miles north of the village of Brailsford, and may be found on Google Maps. The observatory is available for use by individual members at any time after some simple training. A barbecue is held at the observatory on the first Saturday in July instead of a meeting at The Friend's Meeting House that month. The society also takes part in a number of public events and observing evenings during the year, at which members share their enthusiasm for the night sky and bring along their telescopes. An annual trip provides the opportunity for members to visit a different site of astronomical or space interest within the UK each year. Several of our members photograph the night sky and our picture gallery is entirely comprised of DDAS member's work.

For further details please email the DDAS Secretary . Find our meeting location on Google Maps.
OUR NEXT OBSERVING SESSION will be held on Saturday 15th February 2025 from 7:30 pm onwards at the Society's Flamsteed Observatory.

Need advice on getting into astronomy, or on telescopes, binoculars or cameras? - just ask! For more details please email the DDAS Secretary . Our observatory may be found on Google Maps. Please note that anyone visiting our observatory and site, be they members or non-members, do so entirely at their own risk.

On the afternoon of Saturday 18th May 2024, we were delighted to welcome Dr Allan Chapman from Wadham College, Oxford, to deliver a lecture at Derby Museum on John Flamsteed - Derby's Gift to Astronomy and Founder of the Royal Greenwich Observatory. Here is a selection of DDAS members photos of the event.
AURORA LIGHTS UP SKIES FOR DDAS 50TH ANNIVERSARY PARTY... On the evening of Friday 10th May 2024, a spectacular auroral display lit up the skies over the UK. Many DDAS members were quick to observe and photograph this marvel. This included a group of members who were the last to leave the DDAS 50th Anniversary Party at the Littleover Social Club in Derby that evening, who witnessed the spectacle from the club car park! What a fantastic coincidence that it occurred on that evening! Here is a selection of DDAS members photos of the spectacle. Five months later another auroral display on the 10th October 2024 graced our skies.
ASTEROID 69273 DERBYASTROThe Derby & District Astronomical Society is delighted to announce that we now have an asteroid named after us! Thanks to a suggestion made by DDAS member Mike Dumelow, and the work of DDAS member Anthony Southwell in conjunction with the International Astronomical Union (IAU) Working Group for Small Bodies Nomenclature (WGSBN), our 50th anniversary year is now marked by a solar system body with our name on it! Asteroid 69273 Derbyastro (1989 TN1) is a main belt asteroid discovered by English astronomer Brian G. W. Manning at Stakenbridge Observatory near Kidderminster in October 1989. It measures 4.6 km in diameter, has an absolute magnitude of 14.6, and takes 4.6 years to orbit the Sun, with an orbit lying between Mars and Jupiter that is inclined 11 degrees to the plane of the ecliptic. Our naming citation reads: 'The Derby and District Astronomical Society is based in Derby, England and was founded in 1974 by Jane Kirk. The society holds monthly meetings and engages in public and educational activities. It also operates the Flamsteed Observatory and runs monthly public viewing nights.'. View our entry in the WGSBN Bulletin. More details of our asteroid my be found at the JPL Small-Body Database Lookup.
STARGAZING ON CATHEDRAL GREEN A GREAT SUCCESS... On Wednesday 17th April 2024, DDAS members, in collaboration with Derby Museums and Derby Live, put on an evening of stargazing on Cathedral Green. A photo journal of the event can be seen here.
