Venus, through my 8-inch dobsonian telescope, in the late afternoon from my house north of New York City.
It's easy to see that Venus is a little bit more than half-full at this point. Venus is harder to find in the daylight, but the bright background can make it easier to see the phase of Venus. Sometimes the phase is hard to see at night because Venus is so bright. I've posted details at my Heads UP! blog at http://bkellysky.wordpress.com/ bob |

Wow. Thanks. I do believe that's one of the best Earth-based images of Venus I have ever seen.

Agreed. I've always heard that Venus was often best viewed in daylight; now I believe it!

I watched the most recent occultation of Venus by the moon with my telescope (14 cm reflector). It was definitely daylight, sun was up and all. Couldn't see Venus with the naked eye but could certainly see it through the telescope.
As bkellysky said, it definitely looks better against the background (foreground I guess) of the sky. The lighting difference isn't so great and you can much better make out the shape of the planet's phase. It's more challenging to do, but definitely go out and observe Venus during the daytime.

Crescent Venus with a Canon XS and my 8-inch dobsonian telescope.
Venus is in front of the sun, in the sky about a fist width to the upper right of the sun (the distance increases every day). I was able to find Venus in 8x25 binoculars, then pointed my telescope in the same area. Venus is large for a planet and a thin crescent. See my blog for the full photo, cropped here to save space. The rainbow colors are due to the turbulent atmosphere and camera motion. Venus was only about 10 degrees above the horizon at the time, a half hour after sunrise. I haven't seen it without binoculars, but Venus is amazingly bright once you find it and the crescent shape could be seen by other people with the binoculars when I told them where to look. bob http://bkellysky.wordpress.com/ |

Nice one, Bob - though I was a bit before reading on your blog "...I blocked out the sun".
Thank goodness for that. Andy |

Venus was impossible to miss, low in the southeast, less than 30 minutes before sunrise this morning.
It showed a tiny crescent shape in 8x25 binoculars, which was easier to see as the sky got brighter. I'll try to get a photo Thursday morning (the forecast for Wednesday morning is cloudy). bob |

Anytime up to an hour before sunrise, Venus is brilliant. I've posted an example at http://bkellysky.wordpress.com/

This morning's photo of a skyscape including Venus and Saturn is at my blog (at 3MB, too big for this server)
