How to image Omicron Velorum Cluster
Omicron Velorum Cluster sits in the constellation Vela at right ascension 08h 40m 32s and declination -53° 02' 08". 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.
