M51 - The Whirlpool Galaxy

M51

(Click on the picture above to go to the main image.)

The smaller galaxy at the bottom of the image (NGC 5195) is slightly further away than the larger galaxy (NGC 5194) and has passed close enough to distort the outer spiral arms of its neighbor.

This is an updated image. For comparison, check out the previous ST-6 image.

Also see my ST-6 image of Supernova 1994I.

I took this picture from my driveway.
