How to image Butterfly Galaxies
Butterfly Galaxies sits in the constellation Virgo at right ascension 12h 36m 33s and declination +11° 15' 29". 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. As a galaxy, Butterfly Galaxies needs the darkest skies you can find: surface brightness, not just apparent magnitude, drives whether it will lift out of the gradient.
