How to image Table of Scorpius
Table of Scorpius sits in the constellation Scorpius at right ascension 16h 54m 11s and declination -41° 49' 27". To frame and integrate it well, AstroPlanner will compute the optimal moonless window for tonight from your location, the field-of-view fit against your sensor and focal length, the suggested total integration time given your aperture and sky Bortle class, and a cloud-aware schedule that drops it from the plan if your nearest cloud forecast spike overlaps the best altitude window.
