Venus is getting large enough now to show it's phase without magnification, for those with excellent vision. To cut the glare, try using a fairly dark neutral-density ("moon") filter, or a pair of polarizing filters adjusted to block most of the transmitted light. A dark sunglass will work in a pinch. Another trick is to use a pinhole aperture. Punch a tiny hole in an index card and sight through the hole an inch from your eye. With my glasses on, I can just tell that the planet is apparently wider than it is tall as of this evening. It will get much larger in the next couple of weeks leading up to the transit, but don't wait too long or you'll be trying to detect the crescent in the morning instead of evening. Please post if you clearly discern the crescent without magnification, thanks! __________________________________ Do you Yahoo!? Yahoo!

To cut glare also try viewing after sundown, but before dark. I like twilight viewing of Venus because I feel I can see more detail. I could see the crescent in the twilight.

Testing, no need to reply. I want to see if this will get through to me via the discussion group. Last night I tried to set up some filters and I think I accidentally filtered out some email addresses that I DO want mail from. This is a test to see if the astronomy news group is among those. Meanwhile, I don't know how to undo filters in Eudora, so will have to get our systems people to help me. Thanks, Joe
