I've seen it once. Through Zane Hammond's 25" Dobzilla. I can't remember what eyepiece we were using, but, it was easily split and the colour could be made out, too. It was a rather beautiful sight.
Interestingly, using the same telescope, we were able to see faint colour in the Orion Nebula and easily see the Running Man Nebula. Top instrument, that!
