Michel Deconinck (150mm refractor,300mm Newtonian) | |
This is a pastel (white on black) made of Venus with my refractor 152/1200. To improve the contrast I used one set of two filters: orange plus green,#12 and #58 together. A red filter was used to detect the atmosphere limit. The used magnification was 300x. [Michel Deconinck : [Artignosc-sur-Verdon,France]]
