Planetary imaging

Lucky imaging on the moon with Moana

The scope was designed for deep sky imaging, but can be used for planetary imaging as well. The corrected field of view exceeds 30 arc minutes, so the full moon does fit in a single frame. For planets, the focal length of 1325mm is short (typically I like about 4 time this amount for planetary imaging), however, most of the time planetary imaging is limited by seeing, not by the focal length of the instrument. With 0.59 arcsec by pixel and the possibility to drizzle, Moana happens to be a decent planetary scope. On good days, with excellent seeing, performance could be increase with the use of a x4 Powermate and on site collimation. On most days, the setting is seeing limited.

I typically record lucky imaging videos with Fire-Capture, and remotely stack the videos with Auto-Stakkert-3, as the video files can get huge very quickly. Below I distribute RGB frames for the Moon and Jupiter.
