Mercury in transit on the disk of the Sun, at 11:01 am MST on November 11, 2019, only 3 minutes before egress. I shot from home in southern Alberta on a beautfully clear morning but with temperature a chilly -20° C at sunrise and warming to -12° by end of transit.

THis was the last transit of Mercury until 2032, but the last visible from North America until 2049!

I shot this with the cropped frame Canon 60Da camera on the Astro-Physics 105mm Traveler refractor with a 2X Barlow for an effective focal length of 1200mm at f/12. This was 1/500 second at ISO 100 through a metal-coated Thousand Oaks solar filter yielding the yellow tint.
