How to image NGC 288
NGC 288 sits in the constellation Sculptor at right ascension 00h 52m 47s and declination -26° 35' 24". 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.
