Deefstes, I have to compliment you as I think that that sequential arc of moon pics, with the building in the foreground, is fantastic! :clap: :clap: :clap: Did you leave the shutter open and expose by alternately removing and covering the lens with the cap? The black-and-white close-up is also tops. Thanks for sharing. :dance:

Thanks mate. No, I had the camera on a tripod and used a remote shutter release to take a picture every ten minutes without the camera moving. I then basically just combined all the images afterwards.

I think it could be an interesting idea to leave the shutter open for the 2.5 hours and just cover/uncover the lens for every exposure. I think I'll give that a try some time. In a way it is more "purist" as it would not require much or any post processing.

And the "black and white" picture is actually not black and white. It's just that the sky was black and the moon was white :D

For those interested, have a look at this unbelievable picture of the lunar eclipse. It is also a combination of several pictures taken during totality, eight in fact, each of them a 40 seconds exposure. There is not a great deal of information available on how the image was taken but I would assume the camera must have been on a equatorial mount to allow tracking of the moon so as to avoid motion blur.

Here are two more sensational shots. The first one was taken of this same eclipse but from Hungary. The photographer had a similar idea than me but clearly a better lens and also a better vantage point. His being on a much higher latitude means that the moon didn't climb as high in the sky making it possible for him to get the full eclipse fairly close to a foreground building.

The second one was taken of the March 4, 2007 eclipse from Iran. This guy left the lens open for the entire umbral and total stage of the eclipse. This resulted in a sort of star trail (in fact, you can see some star trails on the picture as well). Notice how the trail starts bright (full moon), fades to red (eclipsed moon), and then brightens again (full moon). Of course, this would have been far more difficult with the recent eclipse as it was a very long eclipse and would have required a shutter opening of something like 2.5 hours.
