1350-161 - The Sun setting into a pall of forest fire smoke over Alberta from fires in B.C. and elsewhere, on August 17, 2018. This shows the dimming and reddening of the Sun as it set, with it disappearing from view long before it reached the horizon.

1350-97 - The partial eclipse of the Sun, October 23, 2014, as seen from Jasper, Alberta, shot under clear skies through a mylar filter, on the front of a 66mm f/6 apo refractor using the Canon 60Da for 1/8000 (!) sec exposure at ISO 100. The colours are natural, with the mylar filter providing a neutral 'white light' image. The big sunspot on the Sun that day is just disappearing behind the Moon's limb. The mylar filter gave a white Sun, its natural colour, but I have tinted the Sun's disk yellow for a more pleasing view that is not just white Sun/black sky.

1350-130 - Particularly large groups of sunspots on the Sun on September 4, 2017. The group at bottom is AR 2673, the group at top is 2674. The small spot at left on the emerging limb is AR 2677, while the groups disappearing at right are AR 2675 (top) and AR 2776.
