    Hello Gere,
    
    For getting started I'd just recommend a pair of standard-issue 
    mid-sized binos -- I use a pair of 8 x 40s, giving a 5mm exit 
    pupil size ( objective size / magnification ).  The current 
    theory is that's the optimum for viewing point-sources at night -- 
    7mm is better for wide, faint targets such as galaxies.
    
    The things that I'd look for if I were to buy a pair of binos
    now would be:
    
    1. 5mm exit pupil;
    2. Lowish magnification ( maximum of 8 or so );
    3. Sufficient eye relief so that you don't have to hold
       the binos pressed against your eye sockets;
    4. Light weight.  
    
    Lidl often have decent Bresser / Meade binos on special; you 
    might get lucky if there's one near you.
    
    But the best equipment by far -- a dark site.  I can only
    dream...
