Distance learning has long been a part of society. The important thing is that you can get your MBA online through distance learning, no matter what your schedule, budget, or learning style.

I couldn’t get a good dark sky / clear horizon / cloudless sunset. But then, I think the UK is one of the hardest places to find a dark sky.

The faintest object I’ve ever seen from the UK was the Ring Nebula when it was nearly overhead … until it was occluded by a power cable (I then lost the track).

Still, the linked photo (from Bruce Langdon’s comment) is very nice.

Venus may also be brighter due to the planet’s phases. Since Venus is farther away it should be on the far side of the sun and therefore has most of its sunlit surface facing us. I don’t know what phase Mercury is in though. The lit side could be facing us or away from us.

Here’s a nice picture of the planets from from Mount Hamilton:

As to the directions being reversed in the southern hemisphere:
Being in the southern hemisphere could be compared to standing on your head. If you stand on your head facing the same direction as when you were standing, left and right will switch directions from your previous viewpoint.

Although now that I think of it, I suppose it would be more precise to say that the their relative positions with respect to the horizon would rotate the same number of degrees as the difference in latitude. You’d have to go from the north pole to the south pole to completely reverse left and right.

Mark Bukal, plane of the ecliptic? The planets are roughly in line. While the Earth’s axis is tilted, there’s a definite plane that matches the plane of the ecliptic that cuts through the Earth. That plane will define a North and South. North of that line, the planets will be south of you and fall more left as they are higher in the sky. South of that plane the planets will be north of you and fall more right as they are higher in the sky. The same way the Sun’s path in the sky is either slightly south or slightly north for most people, and not directly overhead.

saw it…awesome; Took my 7 year old (who has a reasonable interest in astronomy) to show it with a 8 inch Dob. He was mesmerized.

I’m confused. You said that an observer in the southern hemisphere should reverse left and right. For objects in the western sky, would they really be reversed? (I understand how something in the southern sky in Ohio would be in the northern sky in Chile, thus switching left and right, since the observers would be facing each other. I’m thinking that this is different though.)
