Sunspots - March 2000
|
March 2000 was a good time for
sunspots as these images by Graham Ensor show. Graham projected
the Sun's disk using his 80 year old Watson & Sons 'Century'
3-inch brass refractor. The resulting image was captured with
a Sony Mavica digital camera and processed in Photoshop to show
detail and structure. |
