Diamond dust halos on the night of 12/13 January – part I

0569

With this post starts the presentation of January 12/13 night results. All the photos are from the beam. The image above is a singe frame with 30s exposure. Just basic halos there. In the gallery images the emphasis is on the column 3-5-7 which shows up in crystals of psychedelic colors. The individual frames are all 30s exposures. The lamp is the usual 5 degrees below horizon.
