How to image NGC 2245
NGC 2245 sits in the constellation Monoceros at right ascension 06h 32m 41s and declination +10° 09' 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.
