AAVSO Observer Code
Variable Stars South (VSS)
Full Name
Roy Axelsen
Kenmore, Queensland, AU
Background/Interesting Fact
My first visual observation submitted to the AAVSO was made on 15 April 2002, and for some time I remained a visual observer. Then I moved into PEP, but did not operate within the AAVSO programme because I wanted to learn two colour photometry (the programme used a V filter only). My first submitted DSLR photometry observation was made on 24 April 2015, and most of my DSLR observations have been time series of delta Scuti stars, with a few publications in the JAAVSO. In 2006 I joined the Comparison Star Database Working Group, chaired by Vance Petriew (PVA), which created the forerunner of the database which now underlies the VSP. In 2019 I purchased a cooled monochrome CMOS camera and filter wheel for photometry and curently study southern eclipsing binaries with this camera imaging through a 200mm Canon camera lens. I live in Brisbane on the central part of the east coast of Australia, have an active membership of the Astronomical Association of Queensland, a local amateur astronomical society, and am also a member of Variable Stars South.
