Saturn 12.11.2011

[riklaunim]

The Lord of The Rings have returned. Captured before sunrise in no so stable conditions. C11 + Basler Ace + Atmospheric dispersion corrector...

f/20; IrRGB 5:15 UT:

f/20; Yellow, ProPlanet 742; 5:06 and 5:15

f/20; Yellow, RedLum; 5:19 and 5:21

Some avis were spoiled by Basler artifacts. I wonder why Saturn so easily gets those artifacts.

[Klesk14]

Those are great images, I'm looking forward to seeing Saturn myself.

[rawhead]

Lovely shot through the murk Rik

Another target. Wahoo

How usefull is the Dispersion Corrector?

Cheers

[Virgoman]

Great shots so early in the season, Rik. I second Rawhead regarding the dispersal corrector? Best regards.

[riklaunim]

Atmospheric dispersion corrector is quite essential for imaging planets that are low (like Saturn), and they do help on those that are higher. It corrects the focus point of each wavelength - to focus at once (while atmosphere spreads focus).

When it's corrected broad filters may be used (like L - ir/uv cut, or other like my #12 yellow longpass filter) without any blur caused by atmoshperic defocus. Visually dispersion shows itself as the red/blue edge.

Nice to see Saturn back. You have inspired me to get up early and try some imaging Saturn and Mars myself.

[Space Cowboy]

Wow! I had no idea Saturn was up already. Super images Rik and so nice to see how much more the rings have opened out!

[Whirlwind]

Lovely image, but what is a Basler artifact?

[riklaunim]

Ring-like artifact:

It's not as rings in old DMK at 60 FPS, it's quite random, but 99% of them occurs on Saturn

Great set of pics! Can't wait to have a go at this when the clouds stay away for long enough!

[Ringrocket]

Super, it's back

I was so busy with Jupiter I almost forgot

[Admiral Crispy]

Wow, these are some pretty amazing pics! Its nice to see that the rings are beginning to really open out and make Cassini more obvious! And even a bit of the Encke gap too! Awesome!

[FranckiM06]

Wow, it is splendid image of Saturn. Also, we can see now the ring is more open.
