Astrosimo vs GREYN

Point your iPhone at the night sky and come away with a real astrophoto. Astrosimo finds tonight's best targets, helps you align, then focuses, captures and stacks on the phone. TONIGHT Tonight ranks targets your phone can actually capture, based on your night, location, weather and moonlight. Browse the Moon, star fields, star clusters, nebulae and galaxies, including Messier objects and showpiece deep-sky targets. Planets are included for locating and framing. Detail on planets needs added optics, so Tonight does not recommend them for automatic phone capture. CAPTURE Aim, align and hold still. Astrosimo handles focus, alignment and stacking, with a live view as the stack builds. Gradient removal and stretch run automatically.
