Northern Skies without guiding test

This image of the northern night sky was taken with multiple short exposures (30 secs) without guiding (just sitting on the tripod) with my Canon t3i and then processed with Deep Sky Stacker. Deep Sky Stacker is a program that will take astrophotography images of the same subject and stack them together to make it look like a much longer exposure. This one was about 8 images. You will see that the trees are blurred but the stars are not ! It helps bring out fine detail in the northern part of the Milky Way. With a little more post production (see next image) I made the Milky Way appear even more, but this was simply a test.

Note: if you click on this first image a larger view will be shown. Then if you use your left/right arrows on your keyboard you can toggle quickly between each image.
