I just came across this Free Book on Smartphone Astro- photography which seems to be growing in popularity. Its a Full Color 192 Page book downloadable as a PDF
Its remarkable that a book containing so much information with its beautiful images has been provided Free to the Public.
Having just purchased a pair of Celestron Echelon 16x80 Binoculars and a Celestron Nexyz Smart Phone Holder this will be the ideal reading companion.
