In late November 2013 the BBC’s The Sky at Night team travelled to La Palma in the Canary Islands to observe and study a handful of bright comets — including C/2012 S1 (ISON) and C/2013 R1 (Lovejoy) — with the professional telescopes located at the Roque de Los Muchachos Observatory.
Below are some of my personal photos from the filming trip, including some shots of ISON and Lovejoy taken with amateur equipment.
