Image Description:

This is my first webcam shot of the moon, using the Orion ED80 rig I used to image saturn the same night. More of an experiment than anything else. I used the Lunar and Planetary Institute's Consolidated Lunar Atlas and the Virtual Moon Atlas to figure out what portion of the moon I had captured. North is up.

Image Description:

This is a closeup of the Western portion of IC 1396, a Dark Nebula known as the Elephant Trunk in the constellation of Cepheus. The Dark Nebula (LDN 1105) suggests the elephant-trunk shape, while vdB 142 actually refers to the tiny patch of Reflection Nebula around the 9th mag star HD 239710 near the elephant's snout (see the mouse-over labels). This image is "First Light post-nasal surgery" <grin>, and I'm pretty happy with it considering the poor seeing and transparency. It could definitely use some Hα exposures to improve the contrast. A higher resolution image is also available. North is up.
