I’m still working on the translation, but still:
Astronomy with Binoculars is an introduction into stargazing with a simple pair of binoculars. It is also an experiment: It is avaiable as EBook and as real, softcover book via Amazon (in colour or black and white, and with a small observation log – you can find the links on the right hand side), but you can also find the whole content on this webpage (with adaptions to the medium) . You can find the star charts from the end of the book here as PDF for download. The test chart for the resolution of your optics can be found here.
