Webcam imaging of the Moon (and Planets)

Coming up on 10th/11th February there will be a Penumbral Eclipse of the Moon. There are three kinds of lunar eclipses: total, partial and penumbral. A penumbral eclipse is very subtle. At no time does a dark bite appear to be taken out of the moon. Instead, at mid-eclipse, observant people will notice a shading on the moon’s face. They might say the moon looks strange. Others will notice nothing at all. We’ll use this as a background to discuss webcam imaging and processing. We’ll also have our regular items – planetary round-up, Cullen Objects and a Book of the Month.
