In December 2012 I was humbled to receive the Bill Bradfield Astronomy Award.
From the ASSA awards page:
The award is named after Bill Bradfield, a Past President and Honorary Life Member of the Society and discoverer of 17 comets – the most comet discoveries by an amateur astronomer in the 20th century.
The description of my award on that page is as follows:
David received the Award for the creation and development of VStar. VStar is a variable star data visualisation and analysis software tool, which David has provided free to the astronomical community. Visit the VStar web site to download the software and for more information.
The physical award has been sitting next to my 2011 AAVSO Director’s award but it took awhile for the web page to be updated.
