Several nights ago I easily split 72 Pegasi. The Burnhams handbook states a seperation of only .5 sec. I observed the star high overhead near the meridian. My 10" f/11 R30 handled it quite easily at 625x and 815x. The clean black void between the componets was estimated to be just as wide as the airy discs were in diameter!! 
I can't recall the exact specs on an aperture of this level but believe it to be about .465 arc sec. I'm hopefull that the new Raycorrs will allow a "cleaner" split although I'm sure that less than perfect seeing conditions were fighting me that night. Jupiter was high in the east about half way to the meridian also. So I rolled over to it and was tongue tied....something of a rarity for me IMOH. ;D Even with a Moon and cirrus in the sky Jupiter shown brightly. I have seen skies much better than tonight and I can't contain my eagerness. Istar's lens is really living up to it's "hype" which is a pleasant experience.

Well I can't wait for Jupiter. There a few clouds in the way but I'm hoping for a clear area out west to move in after bit. ::)Mike
The weight is what matters most.. and we took this chalenge seriously. How these perform side to side with fully closed tube design will be known soon.. say February 2013..
