Hi josue2503! :smile:

Hint: where (roughly) are the two foci of a shaving mirror? :wink:
 
I wouldn't recommend it. Would be kinda hard fitting it onto a cell. Check with your local astronomy club to see if they have any primary mirrors for sale, you might luck out.
 
Plus, the quality of the mirror can't possibly be good enough for astonomy.
