Just one more question: how can I disable the AF and set the focus to infinite with the 11-22 or 32mm?
Some lens have a specific leverage but EF-Ms don't (the 32mm has but I don't know what it serves..)

One of the SHOOT menus has a Focus mode setting which appears when you fit a Canon EF-M lens, that lets you choose between AF, MF or AF+MF. Make sure the Retract lens on power off is Disabled in the C.Fn menus (I can't be specific which menu as I don't have an M50). Use the screen magnification to focus manually on a bright star or planet, refine the focus on the dimmer stars that appear when you get close.  (Using the articulated rear screen can save you a crick in the neck. Use a tripod.) The Canon EF-M lenses don't have a hard stop at infinity, and the hard stop on other lenses can't be relied upon for sharp focus on stars.
