#14 there is an app for that. You can use a telescope or your smart phone to see what is in a particular area of the sky on any given night without asking a Druid.
I personally prefer paper charts (or at least PDF on my tablet) to using electronic anything, but, my new-to-me scope has Sky Commander Digital setting circles, and a blu-ray connection to Sky-Safari 5 on my tablet. It also has a Tel-rad instead of a proper finder, something I hope to fix soon.
If all is working right, I can either look up items on the sky commander and it will tell me where to point, or, I can use the tablet to find an item and point the scope. I mostly use it to tell me what I am looking at.
I can find 95% of the Messier objects by memory, it’s the NGC objects I can’t remember too well.
If you are going to have one app for astronomy, Sky Safari is the best by a LONG shot.
