Winners of WSC: General category

The following post list the winners of WSC 2017.

Comment from the jury:  A look to our stars and planets: which topic could be more suitable for introducing Science to the general public… The beauty of astronomical images is always eye-catching, hence it has been quite obvious to see this theme among the WSC finalists of the last phase. This image of the Sun and the Moon provides a glimpse in different areas of research concerning nearby celestial objects: the celestial mechanics of the eclipse, the orography of the surface of our satellite, the physics of the corona of our star. In the end, even if an image of an eclipse is ordinary, this image is a much-elaborated variation that also stresses the importance of image processing to extract meaningful information. For these reasons, it is also one of the most widely used on Wikimedia platforms amongst those uploaded for WSC2017.

Comment from the author (Michael S. Adler): I have always been interested in astronomy and as a child had a 4″ telescope. Over the years I also developed an interest in photography mainly with a focus on travels all around the world such as recently to Nepal twice, Scotland 3 times, Iceland 3 times, New Zealand 3 times, Spitzbergen, and South America and Antarctica. About 20 years ago I acquired a high quality 6″ refractor and then after retirement from GE in 2000, I also equipped the telescope with an astronomical camera and other equipment for doing astro photography. Then in 2014 I built an observatory here in Jackson WY and added a 12.5″ and a 20″ telescope.

The eclipse was a natural extension of this since Jackson was in the area of totality and represented a once in a lifetime opportunity. I ended up using the 6″ telescope with a focal reducer giving it a 900mm fl at f6. The camera was a Canon 5D Mk4 and was shot using exposure bracketing in 7 steps from 1/8000 to 1/2 a second. The images were combined in Photomatix Pro and Photoshop CC 2017 was used as the final step. I was very lucky as the weather was perfect for the eclipse.
