The Terminator

Moon Terminator Detail on 2/17/08

Tonight, we had storms and then all of a sudden, it was clear – very humid, but clear. I brought the scope out and after setting up realized there was too much wind for any long exposures, so I headed straight for the Moon. It was quite bright, casting shadows on the ground and after taking an overall shot (used above to display the detailed area) I decided to use my 3X Barlow to take a series of images that I could combine into a larger panorama. The terminator is the line where the shadow and light come together as the moon grows or shrinks and is usually the most interesting place to look at the moon. This is because shadows are magnified near the terminator because of the angle that the light shines on the features found there. I was able to stitch together this series of 18 images that cover the entire length of the terminator. If you’d like to really see the detail click on the image and you can see a much larger version (go to “all sizes”) or see notes about some of the features visible in the image. You can see how Sinus Iridum which I imaged yesterday has changed just in the past 24 hours.
