You need to set the exposure according to the '600 rule' to avoid star trails. (600 / focal length = exposure time) So for a 50mm lens the exposure time is 12. A fast wide angle lens would give a full capture of the Milky Way while allowing longer exposure times without trails. (drools at Zeiss Distagon 21
)
My home is quite far from the city so it's pretty dark here in the midnight, no light pollution issues. Yesterday I could see the arm of Milky Way with my bare eyes so tried to give it a go. (A mobile app like Sky Map is very helpful to locate the position of deep sky stuffs.)
