A "greatest hits" sampler of my favourite astrophotos, with images of all types of celestial objects using a variety of shooting techniques.
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.
