This star is
located near a mag. 5 line of stars between Delta and Gamma Ori.
Although this is a binocular object, it took a very steady hand to detect the mag. 7.1 companion at 32". I detected the colours in the 25X100 as Pale or creamy White and Pale Blue in a dullish field. Comments: This is one of
three double stars in this group we visited in 33 Doubles, Orion and is
worth revisiting with the telescope.

Toughie. Took
time to verify split. Thought it was a flare at first, but other stars
didn't exhibit same flare, finally said yes, it was double.
