Notes:
For understanding DIs and how they are calculated, please read this article!
(*) Distance, magnitudes and PAs are from Burnham's Celestial Handbook,so updated values can show some differences. Due to this, DI (DifficultyIndex) are given for Burnham's data, and for example, since Castor is moreopened than 1.8", the DI is more low than 83.
(1): Separation in 37 Pegasus is an estimation from members of this Group.
