How bright does a star have to be to be visible with a small telescope in

About magnitude 1 (Antares) in broad daylight with my 12" LX200. A

polarizing
filter can help improve contrast. You need accurate goto or you probably

won't
find any stars.

I've seen Vega, Sirius, Saturn with just binoculars, and Jupiter and Venus

naked
eye.


I've done Satrun naked eye. As Chris says, there is not much contrast with
the background sky. It helps to get it when it is very close to the moon
(for reference). This past summer Mars was also seen naked eye in daylight
(albeit just before sunset) by several observers.
