Who is the ARO?

Hi, and welcome to my website.  My name is Jim Thompson, and I'm an Aerospace Engineer working and living in Ottawa, Ontario, Canada.  I've created this site to document my journey into and through the field of amateur astronomy.  As a boy growing up in south-eastern Ontario I was an avid fan of star gazing.  Even then I would set my alarm and get up in the wee hours of the morning just to see the Perseids at their peek, or catch a glimpse of Orion's belt.  As I got older however, grown-up distractions like university, work, and family pushed astronomy to the side.  Now that I'm in my 50's, I have rekindled my interest in astronomy after its >20 year hiatus, inspired to a large extent by my kids.
