NightCap Camera app for iPhone

I forget exactly where I learned about NightCap Camera.  I think in an astronomy magazine.  NightCap Camera is an app for the iPhone that helps with low light situation and sounded like a possible solution when using the iPhone and an adapter for astrophotography through an eyepiece on a telescope.

I read through the articles on the NightCap Camera website and identified some things I would like to try once I settle on an iPhone adapter to try.

Specifically, the modes for the moon, star and star trails.  It had some options to image galaxy using a telescope but not sure.  But, maybe that would work for planets.
