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 (Difficulty Index) are given for Burnham's data, and for example, since Castor is more opened than 1.8", the DI is more low than 83.
Note: Espin 2625 + PPM 97528 was not originally on our program, but since a lot of members from the group noted this double while watching the total Moon Eclipse on 9th, January, 2001, we have named it as LE-1 (Lunar Eclipse).
