It appears that the charts are delivered as a PDF file and this is not actually a program that runs on the mobile device, is this correct?

J-VIEW BOOK is an e-book, indeed it is not a program. J-VIEW BOOK is compatible with almost multimedia devices. It is delivered both as PDF and JPEG files. You can display charts with programs available on your mobile device.

Are files included that tell what the object actually is? For instance I received chart 143; Object 151 is listed as a galaxy, is there any reference to what the NGC or Messier number is?

For easy purpose, NGC is never written. 151 stands for NGC 151. Catalog IC is designed as 'I' and Messier as 'M'. Anyway, a pdf booklet is sent with J-VIEW BOOK to customer in which all short names are explained (and much more...).

Is J-VIEW BOOK available in other langages ?

J-VIEW BOOK is available in 7 langages: english, spanish, italian, german, dutch, portuguess.
