I took this picture with my HS20 on October 2nd (06-15 am) from NW London.

There was a bright light in the sky which I thought to be the space station , when it turned out to be Jupiter I thought "cool" even better ..

The 4 small white dots are not visible to the naked eye,and I was surprised to see them when I viewed the pic full size.
Once again this camera (30x zoom) amazed me ...



 
Beautiful.

But are you sure they are not flares? Seemed to me they all have similar distances each other, and too straightly linear. Probably reflection within the lens. Not sure though, you could be right.
 
You did Goooooood :D

Hi Leokids,

Originally I thought it was the space station because the dots are so aligned,until some one put me straight on my flickr page.Then I done some googling ..
 
It's cool when the camera sees stuff you can't. I like reviewing macros and seeing details that otherwise aren't visible...at least to my eyes. Did you hand hold it?
 
Yes, most definitely a tripod shot. The four dots are definitely the four "Galilean Moons" based on not only their spacing but their planar orientation at the equatorial plane of the planet. The planet, being a gaseous giant, is oblate, meaning spun wide at its equator due to tidal effects and centrifugal forces. That the four small dots are clearly oriented along the imaginary equatorial plane is proof enough that they are the four largest Jovian moons, Io, Europa, Ganymede, and Callisto.

A very nice image!

Wow, this is now an explanation.
Congrats for the OP. Great job.
 
Hi:

These are the 4 conditions that must be met to see the International Space Station...

The satellite must be above the horizon
The observer must be in darkness (sun below the observer's horizon)
The satellite must be in sunlight (sun above the satellite's horizon)
The correct side of the satellite must be lit

Normally at night the International Spacestation is so close to the Earth that the Earth's shadow from sunlight covers it at night so it can't be seen..The best times are around sunrise and sunset when the Sun is slightly below the horizon and the ISS is above so that the Sun's light still luminates the ISS...

Sometimes at the right angles the reflection of light from the Moon off the solar panels of the ISS makes it somewhat visible...

Also, the ISS moves quite fast in comparison to stars and planets...It moves across the entire horizon in anywhere from 5-10 minutes depending of the path..As such viewing with telescopes is not recommended...Binoculars are/or video cameras are preferred...

P.S. Very nice shot of Jupiter and it's 4 visible moons..Supposedly at least one of those moons even have moons of their own..

There is a really good iPhone app from NASA that details where and when and in what direction you can see the shuttle according to your location

For example my next shuttle sighting opportunity is 10th Nov 4.19AM for 6 minutes approaching from 10 degrees above SSW and departing 12 degrees above ENE at an elevation of 38 degrees

That sounds good I'd like to have a look at that (but don't use mobile phone)
Is there something similar on the web ?

I believe the space shuttle has been end of lifed. For real time ISS tracking here's one if I'm not mistaken: http://www.n2yo.com/?s=25544

Currently over the Indian Ocean in daylight. From that link you can do multi-day predictions of a satellite wrt your locaion, see what's in your location now, etc. It uses IP as a proxy for latitude and longitude of your location to tell you what's above or what will pass over. IP is not always reliable depending on network architecture, but in my case it is.

I find this site to be one of the best, not just for the 'ISS' but for a lot of other satellites, and star charts, sun, moon, planets, etc...

http://www.heavens-above.com/

...you'll need to set your location coordinates (use their place-name database) then bookmark/save the subsequent homepage into your favourites, and your location will then be in the saved URL.

Sort of useless now as they have parked the shuttles.

I checked out the position of the ISS to see if I could capture it one night and by luck it was due to pop out of the shadow for about 5 seconds that night ... I was on pins and needles as the map did not make it quite clear where it would pop out.

When it did it was superb bright and moving pretty quickly. I focused and shot a burst ... not too many, but a few worked ok. Since the magnification was low (a 70-300VR was what I had available), the best I could get was this:

Thanks for the link Dotbalm,I checked it today and it seems it was passing over at 4.30pm. Problem was it was still light and very overcast.But I will be checking it regular ..
