Size Comparison - Day 1, 2, 428 viewsPrime focus, 10"f/5.6, iso 1600
I did no histogram stretching (contrast enhancing) on these three images so the surface brightness has not been changed from the camera's normal response.
The noted diameters are approximate.

Comet 17P/Holmes In 3D33 viewsI "borrowed" an image image Joe Comeau took the evening of Oct 28 (see Joe's album on this site - Comet Holmes 10-28-07) and combined it with one I took the morning of the 29th to produce this 3d image. Joe's image details - 40 25 sec images average stacked in Maxim DL taken in the evening ~ 10:30 pm using a SAC10 camera on a LXD-55 10" F4 scope. My image - single 3 sec exp, iso 1600 on 10" f/5.6 newt. processed with Noise Ninja. Used StereoImage Make V3.03 to combine them into 3D.
