I re-observed this pair with the aid of the hexagonal objective mask
to see how much it would help in splitting them. I have previously
split this pair with 98x without any additional aid. I tiried 48x,
72x, and 120x tonight. I could only split it at the higher
power. Without the mask, I could not split it at all, as the
conditions were such that the image of Rigel proper was considerably
smeared out and obscured the secondary.
