 I found this pair to be difficult, but resolvable during the steadier moments, at 150x. I saw the stars as blue and white

Telescope: Celestron C8
Eyepieces: 25mm, 17mm, 10mm
Magnification:

Fairly dim and tight, only 0.5" wider than 174 but none the less I was able to split this one. I estimnated the PA at 30°, then saw that the southern most star is actually the dimmer by 0.02 mag (by consulting the list on-line) and that I was 180° off. Blue in color.
