Astrophotography

Downtown Toronto is not the ideal location for astrophotography, due to the light pollution and the heat turbulence in the air from roofs all around my backyard, but I finally have a chance to give it a try with digital equipment which can capture an image with a shorter exposure than film would need.

Equipment

I hope to make this stuff work better over time. These are the first attempts, all from my backyard:

. Comet Holmes worked better, but still some trails due to tracking errors


Lyra - Vega is the brightest star, this image shows stars to VMag ~6.5; Canon SD200 15 sec exposure



M57 - a planetary nebula in Lyre - Meade Deep Sky imager, 10 x 15 sec. exposure



M13 - globular cluster in Hercules - Meade Deep Sky imager, 10 x 15 sec. exposure



M31 - Andromeda Galaxy; this light is ~2900 million years old - Meade Deep Sky imager, 10 x 15 sec. exposure
