|[Note Guidelines] Photographer's Note|
|This composition of the Moon is from two photos. The top moon is in Ulsan South Korea(14/03/06) and the bottom is Brisbane Australia(17/04/06). The Korean moon was taken with a Tamron SP AF Di 180mm Macro f3.5 and Kenko Teleplus Pro 300 DG 2.0X and the Australian Moon with CGE-800 Schmidt-Cassegrain Telescope 203. What I find interesting here is that the macro teleconverter combination seemed to do a better job than the telescope. This is just a point of curiousity.|
There are two reasons I placed these two images together. The first is the perspective of these photos taken from 2 hemispheres at roughly the equally opposite latitudes. They are taken just over a month apart. They are both just short of being a full moon. The bottom image from Australia is a few days more shorter of the full moon than the Korean moon. Both moons are roughly the same position and the same height in the sky. What is interesting here is the different views from each hemisphere, how the moon is at opposite positions. I know this should be obvious but when put together like this it puts our location on the earth surface into some form of perspective.
The other point of interest is the varying colours of the moon. The air over Ulsan, South Korea would be probably considered not the best. Ulsan is one of Korea's largest industrial cities. It is the base of operations for HHI, which is Hyundai heavy industry. They make obviously cars but also refine oil and is the largest ship producing port in the world. With that said ther is some pretty awful stuff that goes into the air. Compare this to Brisbane, Australia which is an urban center with alot of open spaces and pockets of bushland. It does have industry but not on the scale as Ulsan. Brisbane's air is very clean most of the time. By now you can see where this is going. The colour of the Ulsan moon although a clear night is very brown and I believe it is the air pollution. Compared to the Australian Moon at the bottom of the picture, which is very white grey. Now I know the moon when it rises will appear different colours as one is looking though a thick part of the earths atmosphere. As the moon slowly gets higher in the sky the colour changes to the more grey colour found here as the atmosphere thins. This was not the case with the Ulsan moon. It remained this colour well passed midnight.
Ok I have ranted on long enough, I can only hope somebody finds this as interesting as I do.

interesting combination, matt! :-)
i did a few moon-shots, too, so i now the
thw one above is nearer and clearer,
but iīve never seen such a golden moon, cool.
and itīs very interesting to see how different
the moon looks on each side of the earth.
good job & take care, thor.
Sure is interesting note!!
Never thought about how the moon looks from different hemispheres.
As for the colour - how did you make sure the metering did not cause the colour difference?

An interesting and unique idea. Well framed. Too bad you weren't able to use the same equipment for both shots. Glad you are having fun with that new lens and evern newer teleconvertor. BTW, HHI only builds the ships as I understand. HMC makes the cars. As for the oil, I am not sure but I think that remains in the hands of SK Petroleum, Samsung and others besides Hyundai.

Excellent capture! The details are superb and interesting note.
Thanks for sharing!

FANTASTIC work Matt! I'm really astronomy freak, and this one of the best Moon pictures I've ever saw. I like your idea to bring together two shots from different hemisphers. Perfect note also!

Hi Matthew, you did a great job whith this two moon from very far places.
I know too how is difficult to shot the moon, because it is moving!!!
I did a picture of the moon too with a poor instrument and i was very surprised of the result.
You can see it in my portfolio.
I do find this comparison VERY interesting, and I wonder how much pollution effected the result?!?
