to identify celestial objects

A short time ago, I received a message from a reader, Peter in Ottawa, regarding sky viewing apps.

I read your April column in the RASC [Journal] with interest.  I'll probably get the [Astro Clock] but what I'm looking for is a program for my portable device to give me a view of the night sky in real time as I point up in different directions, with names of planets, stars and nebulae.  Those visible to the naked eye and binoculars.

I apologised for the delay and recommended SkySafari for its augmented reality and identification features.
