How to image Foxhead Cluster
Foxhead Cluster sits in the constellation Cygnus at right ascension 19h 41m 18s and declination +40° 11' 12". 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.
