Almost any galaxy or nebula that the Celestron Origin Intelligent Home Observatory can find will fit in its field of view in a single shot. But there is a short list of exceptions.

For instance, the Andromeda Galaxy (M31), the nearest major galaxy to our own and a popular first target, stretches about 3° from end to end. And the iconic North America Nebula (NGC 7000), which lies just 2,600 light-years away in Cygnus, spans roughly 2°.

Celestron’s answer is Mosaic Mode, a free update that brings automated mosaic imaging to the Origin smart telescope. In the Origin app, users draw a box around their target.…
