Notes:

1. Stars #1 and #2 are saturated and their magnitudes and colours are approximate. They should be used for guidance only.

2. There are two bright stars in this field with reliable Tycho-2 
magnitudes. The brightest is at 19h 07m 49.1s  +52d 58' 50" with 
V=8.54+/-0.01 and the other is at 19h 07m 37.9s  +52d 54' 47" with 
V=10.43+/-0.04.
