Quote:For deep sky, there may be an advantage to the Delos. Some observers say the Delos have a bit better light transmission than the XW.

Quote:I'm aware that some fellow CNers report to be able to do so. But the noticed differences will almost certainly not been caused by intensity differences but something else. There are lots of possible sources for perceived differences between eyepieces.

Quote:The original question was for a favorite high power eyepiece for planet observation in an f/10 scope. My favorite eyepiece for high-power planet viewing in my C6 f/10 SCT is a Pentax XO 5.1 - amazing as that may sound to some observers. The C6 is my only f/10 scope, but I do have scopes from f/4 to f/13.Mike

It is a n issue I've seen rear its head elsewhere enough to think it worthy of mentioning.Cheers,Pete
