  1. Stones were small but the sky looked very scary (and beautiful). All photo's were taken in Amersfoort, Netherlands (17:50 local time).
  2. Actualy it is a combination of 3 photo's (stitcht it together) because of 18mm lens the photos are shown in a bit of an arc (birdeye view). Thanks for the comments (i didn't like all the hail and rain... but it gives wonderfull photo's).
  3. In Amersfoort, Netherlands. Morning Sunshine (7:35h local time) Afternoon Arcus hailshower (17:35h local time)
  4. at 8 o'clock.... when i was driving (scooter) to work.
  5. wish we had landscapes like that in the Netherlands Wonderfull photos
  6. After photographing 2 bright comets in Januari (McNaught) and November (Holmes), last night the weather was finaly good enough to try to photograph the comet 8P/Tuttle. I used a Canon EOS350D set at 2,5 minutes, 800 ISO and a 100mm telelens piggyback on telescope. The comet itself was a bit hard to see. Here are the results, I hope you enjoy them. On the same evening i also photographed te planet Mars.
  7. more photo's made this morning (15-11-2007) from Amersfoort, Netherlands.
  8. Finaly a short moment (due to clouds and rain) to take photo's of this wonderful comet. (for more info about the comet see www.Spaceweather.com) Also took this photo of the big dipper above Amersfoort's old city center. (to give you an idea of the bad sky conditions i am in).
  9. This is a composite of two photo's made trough my 11,5cm Newton telescoop.
  10. In visible light there was nothing to be seen, but in H-alpha........
  11. Sunspot 960 has a "beta-gamma-delta" magnetic field that harbors energy for powerful X-class solar flares. NOAA forecasters estimate a 20% chance of such a flare during the next 24 hours. A big eruption could trigger ion storms, radio fadeouts and, if all goes well, auroras. For instance, an M3-flare from sunspot 960 on June 1st caused a shortwave fadeout over Europe.
  12. All photos were made with a 400mm F 6.3 telelens (1.6x analog lens so actually 600mm) a Canon Eos 350D piggyback on a telescope. Longest exposure: 40sec on 200 ISO. Enjoy :lol:
