Lasse Nurminen

Early in the morning, driven by the hopes of yesterday's single pillar. Yesterday’s visual booth took place after about half past nine at dawn, so now the idea was to take advantage of an even darker morning. And after all, there was still ice fog even today, and with it the pillars to be photographed again. The best pillar workshops were found in the yard's "backyard", on the actual façade side of Raisio's marina there was nothing more to see on the yard.

Binocular comet Leonard

Matti Helin, Ursa (Länsi-Suomi)

I went to put the car in the heating. I took the camera and tripod with me and pointed the lens towards Arcturus. I grabbed a dozen squares in the breezy twenty-degree frost and then hurried my fingers to warm up by the coffee mug. Nice target and I guess to be my tenth comet.

Light pillars
