As you would expect my presentations are all Variable Star related.  I make no excuse for this, as it's best to talk about stuff you know about!


Talks on Variable Stars don't usually lend themselves to nice astronomical photographs, but I do include lots of interesting animations to graphically demonstrate certain aspects of how variable stars behave, and which tends to keeps the general audience interested.  These talks are aimed at both observers and 'armchair' astronomers, with the exception of the  'How to observe Variable Stars' presentation, which  is definitely one for the active astronomer interested in making valuable Variable Star observations.


I'm prepared to travel up to 150 miles to talk to Astronomical Societies, but this could be extended depending on circumstances.  Travelling expenses only (fuel diesel).


Currently doing the rounds...


Variable Stars - How and Why They Vary!

A talk explaining why some stars vary in brightness - Pulsating, Symbiotic and Cataclysmic stars are covered.  Slightly technical. PowerPoint presentation.  Running time 60 minutes.


Historical Novae

From ancient records to modern day, this talk looks at Novae through the centuries, what the early astronomers thought Novae actually were, and finally a more detailed look at some landmark discoveries of the 19th/20th centuries.  Running time 1 hour. PowerPoint.


An Introduction to Variable Star Observing

A talk specifically put together for the Dalby Forrest Starfest in August 2013 and Norwich AS in October 2013. Would suit a mixed group of active and armchair astronomers.  Here I give a brief account of the science behind a selection of Variable Stars, explain how to observe them and discuss the reasons why we observe them.  A bit of an amalgamation between 'How and why they vary' and 'How to...'.  Running time 60 minutes. PowerPoint.

The Monster in the Crab

The story of the largest black hole yet detected - OJ287.  This is an update to a talk I put together 12 years ago.  It details the discovery of OJ287, Pro-Am campaigns to observe it since the 1990's, the results of these campaigns up to 2019 and the association with gravity waves.  Running time 60 minutes.  Powerpoint presentation.


How to observe Variable Stars

A basic talk on how to make, record & report a visual Variable Star observation, taking in the methods used by both the BAAVSS & AAVSO. Running time 60 minutes.   PowerPoint Presentation. Better suited to an active group!

Variable Stars around the Perseus Double Cluster

A basic talk on the Variable Stars which can be observed in and around the Double Cluster.  Powerpoint.  Running time 45-60 minutes.


Talks to non astronomical groups:

I'm planning on expanding this to include different topics which would be of interest to non astronomical clubs etc.  My first venture into this was a succesful meeting at Canwell Womens Institute in October 2016 where I spoke about womens role in astronomy.

Ladies of the Night - the role of women in astronomy

From Hypatia to Jocelyn Bell Burnell.  Non technical.  Running time 45 minutes.

Legends in the Sky

A look at some of the more popular Greek myths seen in the night sky, and how other cultures see star patterns.  Non technical and probably better suited to a non astronomical audience.  Running time 45 minutes.
