Where is Saturn in sky over Huygens landing site?

Given the known longitude of the Huygens landing site,
how high above the horizon is saturn in the sky?

Would any of the planned imaging views include enough sky
to spot Saturn?

My guess is 'no', that it would be a
waste of bandwidth to even bother to try
for such a picture -- but all the same,
what's the view like?

Thanks,

Saturn is well below horizon at the Huygens landing site. Even if it were
above the horizon, it would still be invisible due to the same thick haze
high in the atmosphere that prevents us from seeing Titan's surface!

Misled but only temporarilly -- my instincts made me ask for certain.

Titan is tidelocked, no? If so there's no possibility to see a Saturn-rise.

Even if it were
above the horizon, it would still be invisible due to the same thick haze
high in the atmosphere that prevents us from seeing Titan's surface!


How opaque is Titan's atmosphere? I recall in Los Angeles I could see
the sun, the moon and even Venus.

True.

Even if it were
above the horizon, it would still be invisible due to the same thick

haze
high in the atmosphere that prevents us from seeing Titan's surface!

Sun's intensity at Saturn is about 1/100 that of Earth. Also, the haze is
expected to diminish lighting by another factor of 10. Overall, it's said to
be 1000 times darker than broad daylight on Earth, which is still about 1000
times brighter than a full moon. A dusky, twilight environment, but still
bright enough to read a newspaper, supposedly. As for the thickness of the
haze, it's completely opaque at visible wavelenths so there's no chance of
seeing stars or anything.

It's too bad; that would have been the space picture to end all space
pictures.
Still, I'm looking forward to some great photos later today.

Actually this site was not available (HTTP 500 error) at the time I wrote
this - can't think why!
