To infinity and beyond (my longest \”lens\”)

Today\’s featured article on the German Wikipedia start page was the one about Hubble Deep Field (English version here). That reminded me about a feature on N24, one of the many private news broadcasters which I had recorded, so after dinner we watched that and learned quite a bit about Hubble.

I told Zuleikha that this space telescope was \”slightly bigger\” than mine, and after explaining the differences (the mirror of mine is 15cm, the one of Hubble 240cm) it made her laugh 😉

Now that she\’s in bed, I played around with my DSLR and the longer one of my two zoom lenses. That E-520 is from 2009, has only 10 Megapixels, and is still working nicely. Here\’s a shot of the telescope head from quite a distance:

To infinity and beyond (my longest \”lens\”)

Took this with aperture f/16 and with indirect lighting from one of my studio strobes. I was about 0.2 stops too high, which I corrected with the Olympus Viewer 3 raw converter, but the image is pretty much like out of camera.

As you can see, the telescope is of the Newtonian type where you look into it from the side. When used as a lens, it has an equivalent focal length of a 1500mm lens on a film camera (real focal length is 750mm, and (Micro) Four Thirds has a \”crop factor\” of 2, compared with 24x36mm film). So this is indeed my longest lens, which gives something like this:

Not quite like Hubble, but a bit easier to handle, isn\’t it? A bit cheaper as well…

Thanks for viewing.
