Q: Will the transit of Venus in a few weeks, be visible at Mars?
Could Oppy (or orbiters) resolve it ??? -------------------- CLA CLL

@Stu: Projecting the sun image on a cardboard shown there is one excellent method and the one that I am going to use.
And quite some of that go for me as well. Like those in the UK I am going to miss the first contact, but weather permits I will potentially be able to see most of the transit since I am further north. |

@Stu: Projecting the sun image on a cardboard shown there is one excellent method and the one that I am going to use. You do know that Sun's IR light can be focusing inside some of glass parts of your binocular which can damage some of them beyond repair...right? When you project Sun image through a telescope, you should use some cheap Kellner, or some other kind of simple eyepiece...because there are no glass parts in focal points. The best way to see Sun is through Baader solar filter which should always be in front of your optical instrument. NEVER BETWEEN your optics and your eyes. Also should be known that this film reduces the intensity of sunlight by 99.999% (optical density 5.0), optical density of 3.8 is not recommended for optical observation (Photo Film OD = 3,8). -------------------- The scientist does not study nature because it is useful; he studies it because he delights in it, and he delights in it because it is beautiful.
