doubles journey continues

Back on 26 July 2017, I had a trip down memory lane considering my interest in double stars, dating back to 1991.

At the time I thought it a fascinating journey—over 26 years—and concluded in the middle of 2017 that it had been a heck of a trip.

Could I have imagined the future, back then? Certainly I was pressing ahead for a certificate program since at least 2014. And I started thinking about measuring doubles as far back as 2008. Still. It still surprises me.

For fun, I thought I'd do another dive in the logs, to review what's happened in the last mere 5 years.
