Description

First Quarter Moon. My main imaging CCD has a minimum exposure of 0.01s which is much too long for the moon with a luminance filter, so this image is a single 0.01s exposure through the Ha filter. Being the very deep red end of the spectrum this probably helps by reducing atmospheric distortion. Using "Lucky imaging", this is the best out of 50 x 0.01s images.
