This came out earlier this year. It is in German, but I think it is well useable with minimal knowledge of German - at least if you manage to translate the names of the constellations
The 144 DSO objects covered are listed with their M or NGC number, and where there is no such number (as with some asterisms, e.g. the "Eiffel Tower" close to Mizar/Alkor), the name is given in English.
Other books for binocular astronomy (e.g. S. Tonkin, Binocular Astronomy; G. Seronik, Binocular Highlights; Scagell/Friedman, Stargazing with Binoculars; Craig/Crossen, Binocular Astronomy; Harrington, Touring the Universe through Binoculars) provide more information in text form; the Big Binoscout is essentially based on graphics, overall perhaps more targeted towards relative beginners rather than experienced observers.
I found it easy to use with its double page structure - one page showing a section of the sky with constellations and the approximate location of the DSO objects, the other page giving precise coordinates / size / brightness and showing a drawing of the objects and a simulation of what the objects look like in a handheld binocular (6 degree image, assuming something like 10x50) or a large binocular (3 degree image, assuming 20x100 or the like), respectively.
And: the pages of the Big Binoscout are fully waterproof, therefore no problem using it in cold nights.
