The brighter(closer) pair, at 0.9" was split at 153x showing the typical "snowman". 
Reaching 368x using my 5mm Pentax smc ortho & 2x Meade barlow, the split was so 
obvious, I could swear I saw a fine line of darkness between the 2 disks! The 
colour of the A star was white, with the B star being noted as blue. Splitting 
this close double reaffirms my suspicion that this 4" refractor has excellent optics.
Btw, the fainter pair, C & D, at 2.3" separation was so wide at 368x, you could 
drive a truck between them. ;^)
