Gassendi Compared
Originally published January 15, 2004
Gassendi Compared The advent of webcams and image compositing and enhancing software has given amateur astronomers with modest size instruments the ability to acquire lunar images that equal or surpass the very best professional images. Now amateurs are pushing up against the resolution of space craft imaging. In this comparison of the lunar crater Gassendi, Dutch astroimager John Sussenbach notes that his image has a resolution of about 0.3 seconds of arc, which is both better than theoretical for an 11" and comparable with the Lunar Orbiter image. Gassendi (diameter 110 km) is another floor-fractured crater, like Posidonius and Petavius. The crater has been shallowed by floor uplift and lava flooding.
