Sirius B
I've been trying for a few months now to split Sirius with my 127 x 1200 ( f 9.4 ) achro and even on nights of steady seeing I can't say conclusively that I've seen "B" , I know the PA and Separation, in other words, where it should be in relation to "A" using that scope and magnification, but no definite sighting.
Can split Rigel and Adhara no problem, which supposedly is a good test to see if your optics are good enough for Sirius, I'll keep trying.
