This image is amazing because of the thinness of the Venus scythe. The thickness is only 0,6", exactly equal to the diffaction limit of my 20 cm telescope! Image realized from the best three frames from a Panasonic DS-15 digital camcorder at the indirect focus of the 20 cm SC f/10, used at full aperture and with a 40mm eyepiece + barlow 3x. Seeing II-III. Bigger image: 35 Kb. |
