Another Mega-Mosaic! This time - what else? - the Christmas Tree Cluster. 7 mosaic imaging sessions from the last few months, restacked from 2396 x 10s frames. Two sessions on the cold and clear winter solstice night: NB filter on one Seestar and built-in LP filter on the other (bright moon and snow reflecting from all angles) - see imaging scene. Bonus handheld cellphone pic w/ Enhance-X mark-up.
