HR4661 (mag6.5&8.2@1.9") - difficult but straight forward split at 160X. The primary was yellow and the very faint, very close in companion a pale white.

Gamma Corvi (mag2.6&9.7@1.1") - failed to split this difficult pair. I tried higher magnifications but it was obvious that the seeing was not good enough. I also suspect the pair requires more aperture to resolve given the large delta magnitude. I'll try again at our Astro camp weekend in a fortnight where we will be at a higher altitude and under pristine dark skies.

Scope Vixen NA140SS with LVW5 giving 160X.
HUGE mag delta indeed Steve..Dawes Limit no good here..
And yes, a bigger aperture, or EXCELLENT seeing will be whats needed here.
Your Vixen combo should do it in excellent seeing still..I didnt manage even a figure eight as seeing ordinary here..
Will attempt one more time..
PS:Getting ready to post Leo Doubles soon.
