This is a quite difficult star hopping session. Start from Arcturus,
hop to star 20,18-->14,15-->31--109-->110 and then hop to stars 5,6 & 10 in
Serpens caput. From star 31 to 109 is very difficult hopping due to long distant
and lack of bright stars. I used two double stars mag5 and star 31 form as right triangle
, the opposite side with right angle is the direction to star 109.
Stars 5,6 & 10 form as triangle, M5 locates near star 5 but outside
the triangle (approximately, star 6-->5-->point to M5).
M5 appeared as round, small, bright center; located on poor star field,
only star 5 are in same FOV.
