Picard Crater in Mare Crisium


The largest crater in Mare Crisium is still quite small.

Observer Comments

Target DescriptionPicard is the largest crater in Mare Crisium, which isn't saying much. The crater is named for 17th century French astronomer and geodesist Jean Picard. Did he inspire the character name of Jean-Luc Picard of Star Trek fame? Perhaps. But, to be clear, a Trekkie didn't name this crater.
Image Capture DescriptionThis capture took place on the same evening as the conjunction of the crescent moon with the Pleiades (M45). So this image was taken "between" stacking of this cluster as part of one of the optional exercises in this program. The good news is that I had time to use the real-time lucky imaging and wavelet sharpening built into SharpCap. The bad news is that I could only use the Askar V configured with reducer to 384mm focal length, in order to be able to image all of M45 and the moon in the same frame.

All that said, it is a useful image and substantially better than the Seestar would have delivered.
