Begin by choosing brighter deep-sky objects as your destination. 
The brightness of an object is measured by its visual magnitude; 
the brighter an object, the lower its magnitude. Choose an object 
with a visual magnitude of 9 or lower. Most beginners start with 
the Messier objects, some of the brightest and most beautiful 
deep-sky objects, first catalogued about 200 years ago by 
French astronomer Charles Messier.

Using your star chart, determine in which constellation your 
object lies and locate that constellation in the night sky. Turn your 
binoculars to face this general direction. Find the brightest star 
in this constellation and center your view on it. Consult your star 
chart again, and determine the next brightest star between your 
currently focused star and your object destination. Move your 
binoculars slightly to focus and center this next star.

Continue on this course, using each star as a guidepost for the 
next, until you reach the area in the sky in which the object of 
your hunt should be seen. Center the object and bring it into 
focus. You’ve just found a deep-sky object.

If the object is still not in view, retrace your starhopping steps and 
start again. Remember, expertise in this hobby will require both 
patience and practice. 

Good luck out there!
