Saturn with NexStar11 GPS and ToUCam Pro II
 |
 |
| This
is two versions of the same image, one (left) stacked and processed
with RegiStax
Version 2, and the other (right) with RegiStax Versio 3. You can see
there are differences, but in the end it's difficult to get any extra
detail using RegiStax 3 simply because of the quality of the original
AVI file captured by the Philips software which came with the Philips
ToUCam Pro II. Exposure details: 1/25th, 15 frames per second,
medium-high gain, using Philips ToUCam Pro II through a Celestron
NexStar 11 GPS using a 2x barlow giving a focal ratio of f/20.
In both cases you can click the image to see a larger version. |

| Both
the above images were taken on December 28th, 2004, using a Philips
ToUCam Pro II through a Celestron NexStar 11 GPS with a 3x barlow.
This was only my third night ever trying to webcam the planets and
it taught me a few lessons. The elevation of Saturn was low and it
was a breezy night, so there was tonnes of turbulence in the atmosphere.
There was also strong moonlight. The formation of frost on the corrector
plate of the NexStar came on fairly early too, which didn't help at
all with the definition of the subject. However, the Cassini Division
is clearly visible in both images, and there is at least one darker
cloud belt visible on Saturn itself. Next time I think I'll wait until
Saturn is near the meridian. Image on left is stacked and processed
with RegiStax 3, while that on the right was done with V2. |

Although
slightly over-sharpened in Adobe Photoshop CS due to an unsharp image
resulting from frost on the corrector plate, this picture shows the
sort of detail which can be seen using a webcam during even unfavourable
conditions. Again the Cassini Division is easy to pick out, and their
is banding detail to be seen on Saturn itself. Not bad for a first
time effort! Looking forward to getting out during more favourable
conditions! |
