The forces of rotation caused red hot masses of stones to be torn away from the Earth and to be thrown into the ether, and this is the origin of the stars.

Took your advice Joe and image M51 for 2 consecutive hours, guiding did not work again, so I did it the OLD FASHION WAY, 120 one minute combined images in MaximDL/CCD.   Was a great night until the Moon came up causing a hazy sky throughout the East and Southeastern skies.  Tried guiding with the software that came with the mount after completing the above image, it showed that it was guiding, star did not go outside the crosshair.  I did not image as it was already 1:30 am Monday and I was tired.

Again M51 (seems to be popular on this site) taken on Saturday evening when the sky was clear. I notice some dust mites on image, need to clean camera. Just over one hour exposure. Also note that there is another galaxy in the lower right hand corner, 14.5 magnitude IC4263, faint but large.

Another night of perfect skies, just before the muggy weather comes in this weekend.  Tuesday evening I took M51 combined one hour exposure.  Orion 80ed on Vixen mount.  There is another galaxy lower left hand corner, 14 mag I.C.4263, highlighted in dim circle.
