How to image Caroline’s Rose
Caroline’s Rose sits in the constellation Cassiopeia at right ascension 23h 56m 60s and declination +56° 43' 48". 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.
