Ving, get a hold of the cambridge star atlas. For each map it lists major multiples for the constellations covered with Mag and separation etc. Unfortunately all the names and designations are upside down

Oh Ving, you will regret that decision, it is annoying sometimes (and satisfying of course).
Try http://www.carbonar.es/s33/33.html a good starting source.

it all started woith the splitting of orionis beta...
twas a clear night. transparencey was good and seeing on a scale of 1-10 would have been about 6 or 7. I dont know why i looked at rigel, maybe to align my finder? but i had the scope at 80X and with the new mask my f6 dob was now f15 great, i found for planets and doubles. anyhow I noticed that there was a faint blob coming off the side of this star so i fiddled with the focus thinking that it was out... it wasnt.
later I cecked it out and behold! it was a double! and suposedly a hard one.
now i wanna chase them.

Hartungs Astronomical Objects for Southern Telescopes (ISBN 0521554918) has an excellent selection of doubles arranged by constellation.

I split alpha centauri with my 60 mm Tasco refractor without even intending to. I was surprised at that after hearing how crap the department store 60 mm refrators are. And that was with the stock eyepieces (I have 2 GSO plossls now).

I read that Sirius' companion is far too close to split right now, and will be another 20 years before they're separated enough to split. I know I can't even see a hint of a companion when I look at Sirius.

Good luck.
I try it every clear night, and neither the Mewlon (7"), or the newt (10") has come close yet.
I have ready that a ND filter can help. In respect of Antares an OIII has been used to facilitate this (in a small scope).

Gary, with my 80mm off axis ap stop (14.25f), at about 234x/308x, on a good night Antares splits fairly easily. No filters req'd. Already has heaps of contrast. ie, no stars vis in background.
Just the facts m'am.
