Lu,
A daytime planet observation requires a good scope for sure. Normally it would take a good scope and a split mirror horizon to pull off a daytime Jupiter observation so I was just surprised that the whole horizon had enough light transmitting ability to make the observation. I can only recommend the Cassens & Plath whole horizon not having tried any other brands.

Greg and James:
Your pair of emails are an excellent example of the controversy of whole-horizon mirrors. But I do have to ask Greg whether his ability to capture a daytime sight of Jupiter was due to using a whole-horizon mirror or something else -- like using a scope on a high-quality sextant.
