@philcameron59 The Cathedral is in Detroit Michigan http://www.detroitcathedral.org
We'd had a little incense going for prayers earlier and I left the thurible over the heat grate while I was at lunch. the sun came from behind the clouds and the light hit the smoke.
Notice the Organ pipes below, nice view of your Cathedral were is it ?
