Total eclipse from Llano National Park, northern Chile, Nov. 3, 1994. Morning sky. Taken with Plaubel Makina 67 camera with Velvia 50 120-format slide film and 80mm fixed lens at f/2.8 at 1/8 sec exposure just after second contact so chromosphere adds red tint to corona. Lunar disk darkened in Photoshop to clean up irradiation and haze. Venus is at upper right of Sun.
February 26, 1979 total solar eclipse Questar 3.5-inch f/16 Maksutov-Cassegrain Kodachrome 64 film 1/8th second exposure Tracked at sidereal rate. Taken from site on Highway 1, near Carberry, Manitoba between Brandon and Winnipeg. A mid-range exposure showing prominences and some inner corona. Image is slightly soft from mis-focus (likely caused by temperature shift after initial focusing). Radial blur mask helped sharpen it up. A black hole mask was added in Photoshop over the Moon's disk to darken lunar disk separate from sky, which was made slightly blue for contrast.
February 26, 1979 total solar eclipse Questar 3.5-inch f/16 Maksutov-Cassegrain Kodachrome 64 film 1/4 second exposure (longest I did at this eclipse since a longer one would have recorded corona beyond the field of view of the scope) Tracked at sidereal rate. Taken from site on Highway 1, near Carberry, Manitoba between Brandon and Winnipeg. A longer exposure showing middle corona. Image is slightly soft from mis-focus (likely caused by temperature shift after initial focusing). Radial Blur filter helped sharpen it up. A black hole mask was added in Photoshop over the Moon's disk to darken lunar disk separate from sky, which was made slightly blue for contrast.
