CHDK In Stratosphere, again!

Dear all,

last saturday I completed a launch of a CHDK-powered high altitude balloon over Italy.

The balloon has flown for about 100 km in a zig-zag fashion,  the complete flight lasted about 2h 40m.

Maximum altitude was about 32 km. I say about because even if the manufacturer said the GPS wouldwork over 18km in this case it didn't and I had to extrapolate the maximum altitude:



The camera was an Ixus 80 (the same model I programmed for the launch in Florida) A total of about 1.000 photos, plus 4 videos (the first one lasts 6 minutes, the other ones 3 minutes each)


Some photos

About 15km over lake Trasimeno, the camera looking down due to strong turbolence


From high altitude (about 29km) looking west, you see the Tirrenian coast of Tuscany, with islands Elba and Capraia.
Further on you can clearly see Corsica. As we are extremely high, the sky is dark and you start seeing that the Earth is indeed round!


Again  the Tuscan coast, mount Argentario, Giglio island. Far away you can barely see Sardinia


Looking east, you see the other coast of Italy (the Hadriatic sea). Along the sea you can see Ancona and the dark spot of Mt Conero. Far away, clouds over the Dalmatian coast.


The videos
Sorry for the crappy quality in youtube, I must learn how to compress them better!!!

wonderful transition from kids playing and dogs barking to silent and winds, up to about 2.500 meters

7.000 meters, very strong turbolence

13.000 meters, still some turbolence

24.000 meters: in the stratosphere.

Astounding silence!! Nobody is there to make noise, and anyware air is so thin (abut 3% of the pressure we are used to)

A couple of panoramas assembled from frames of the videos

At about 1.000 metes above the Chianti hills

in the beginning the balloon went up so straight that I annot even see my house, where I aluched the balloon, as it's directly beneath the balloon, in the "black hole" in the panorama

At about 13.000 metes above the Lake Trasimeno

The turbolence was so trong that we have a very good coverage under the camera...
Some more stitching and mending and I'll complete it!

Hej,
Wow too bad I threw up at the 3rd video, it was much enjoyable until then. ^^

Amazing panos, too.

You totally disrupted work here!  Everyone came over to my computer to see why there  were birds chirping and singing... accompanied by various gleeful shouts in Italiano... quickly followed by scenes of lovely Italian country side.  "Wow!"  "Look at that!"  "100,000 feet?!"

Bravo!

Can you talk about the balloon and the equipment?  How did you track it?  How far did it land from the launch point?  What was the payload weight?  Other interesting stuff?

Thanks!

Wow ! That's excellent, who needs NASA. I'm curious too, how do you track and retrieve the equipment.
Very well done.

yes, i am also interested in details of your equipment, and how did you retrieve the camera...
and how did you make those nice panoramas? i mean, html, flash, and stuff?
