Meetings

All these meetings are held on a Friday in the Junior Hall at the Royal Russell School, Coombe Lane, Croydon, Surrey CR9 5BX, start at 7:45 pm, and finish at 10 pm.

Our society is a registered charity. We do not charge a mandatory admission or membership fee, instead relying on voluntary donations by the following methods:

We try to structure the meetings to appeal to our members and guests of all levels, from beginner to expert. They normally consist of an introductory talk by one of our members, society news or an observers section; then a refreshment break followed by the main lecture where the speaker presents a more in-depth talk. A small nominal charge is made for refreshments.

Friday

16th Nov 2018

Chairman Tony Roberts, on: Astronomical Oddities; strange observations, strange mistakes, strange astronomers. It will look at some of the weirder things that have happened in astronomy (Herschel’s rings of Uranus, the planet Vulcan, that sort of thing).

Schedule detail

There are speakers pledged to give talks, and more details of these will appear on this page, Facebook, and on our forum croydonastro as soon as they are determined and also given at the meetings and the regular email notification to members.

_____________________________________________________________


There are no meetings from mid-July to early September.


Details of our meetings are also available on the CAS Web Calendar found on the home page. Using this calendar you can set up email or SMS text alerts to remind you of the lecture times.

Friday

15th Dec 2017

This will be our regular Christmas meeting. There will be no main talk but members Carl Rich and Pauline Gorman will talk on: Eclipses and Space Toys, and there will be a short video and quiz after an extended break.

Friday

24th Nov 2017

We welcome Prof. Steve Miller who will speak to us on the Cassini/Huygens mission.

Friday

10th Nov 2017

John Timmins will speak to us on: Optical quality and a comparison of optical systems.

John has over 50 years of observing experience, using most brands and types of telescope available to the amateur astronomer. The talk starts with a brief reminder of key telescope developments over the past 400 years.

Critical measurement of optical performance is discussed, directly related to the functionality of modern commercial amateur and professional telescopes.

Based on this analysis, recommendations follow for all types of optical systems with the aim of improving the performance of the amateur's telescope.

Friday

27th Oct 2017

We welcome our own established speaker Konrad Malin-Smith, who will be talking on White Dwarfs, the future of ordinary stars like our Sun. Come and learn what will be its fate and learn many interesting things along the way.

This talk will be preceeded earlier in the meeting by an Extraordinary General Meeting, called because the accounts could not be audited in time for the AGM of 12th May. The agenda is: To approve the 2016/17 accounts.

Friday

13th Oct 2017

We welcome Damian Peach who will present to us a talk on High Resolution Astrophotography.

This talk by the world renowned amateur astronomer will focus on high resolution imaging of the planets using amateur telescopes. From advice for beginners to advanced observers it will show you how to get the most from the equipment you own, and his own examples have been shown on television and many magazines.

Friday

22nd Sept 2017

Dr Tim Rickard will present to us the bright star Vega.

Fifth brightest star in the night sky, described as the second most studied star after the Sun. First star after the Sun to be photographed and heavily studied in early work on spectroscopy and the determination of astronomical distances. Recently used in setting benchmarks for stellar brightness. Work in the last few years revealed more surprising features about Vega. This talk will outline some of the discoveries, both old and new, and how they helped us understand a little more about the universe in general.

Friday

8th Sept 2017

For this first meeting of the 2017-2018 season we start with Ellis Owen on: The birth of stars throughout the Universe.

Molecular clouds are the factories of new stars in our own galaxy and others. In this talk he will discuss their evolution, from initial collapse to the ignition of stars. He will outline their structure, and talk about the magnetic fields which permeate them. He will introduce some of the physical concepts involved in understanding how molecular clouds are supported, and the factors which can affect their evolution - from ultra-high-energy particles to cooling processes. He will discuss how our understanding of star formation and molecular clouds in the nearby Universe can help us to start to understand the formation of stars in the furthest reaches of the cosmos.

Friday

13th July 2018

Prof. Andrew Coates spoke to us on the subject titled ExoMars.

Friday

6th July 2018

James Fradgley from the Wessex Astronomical Society, spoke to us on the subject of Life in the Universe. Are the aliens really there? Astronomical and evolutionary factors for assessing the probability of there being complex life 'out there'.

Friday

22nd June 2018

Member Bernard Winchester presented a talk on: Space and Spirituality. Interviews with astronauts returning from space in articles and news reports often indicate that they feel fundamentally changed by their experiences. So what happens when we "slip the surly bonds of earth to touch the face of God", and why?

Friday

8th June 2018

Our Chairman Tony Roberts presented a talk on the History of the Telescope.

Friday

25th May 2018
