Like this? They are called Planispheres.
Phone apps are more versatile but planispheres don’t need batteries (though you will need a red torch to use one in the dark!)
So you will need batteries after all

Mine too, though when I don’t want to be disturbed I switch to ‘ignore’. 
There is due to be a nova (not supernova) ‘soon’ in the western sky which occurs every 80 years (approx).
It should be visible to us in the evening and may even be visible in daylight depending on where on the planet you are situated.
It is named T Coronae Borealis and is a binary system consisting of a white dwarf star and a red giant star. Lots of info online.

It doesn’t get that bright. It’s normally around mag 2.5. Lots of things are brighter including lots of normal stars. Sirius is about mag -1.5 which is nearly 40 times brighter. Venus is mag -4.6 which is around 240 times brighter.

Betelgeuse in Orion is due to go supernova “soon” in cosmic terms - but “soon” means sometime i the next 100,000 years, so no need to get tinfoil hats ready just yet…
