衝直前だし、季節風が弱まったので、撮影しましたが、
相変わらずシーイングが悪く、眼視でもモニター表示
でも、土星像が拡大収縮飛び跳ね状態で観測になりません。

1月9日と1月13日のSEBの白斑の位置が比較しやすいように体系�Vをもとに２枚の動画を作りました。体系�Vに対して後退しているように見えます。
1月9日は�V＝216.8　1月13日は�V=218.2ですから、同じ経度にあるなら、ほんの少し前進しているように見えるはずですが、それにも関わらず後退しています。
更に云えば、SEB上の模様の多くは後退しているように見えますが、STrZにある白斑はほぼそのままの位置にいます。


シーイングがいまいちで解像度が劣るため期待していなかったのですが、14:43:03(UT)以降の画像を動画にしたところ、SEB上に移動する模様がなんとなくですが、けっこうあるように思われました。

I herewith submit two pictures of  Saturn and its Moons close to the descent of Huygens and  the moment of the 2005 opposition.
I am a first time submitter and hope I have filled out the information in the proper way.
The satellites mosaic is a combination of a 1 sec picture of the moons made with the modified webcxam and a 1/25 sec picture of Saturn alone.
The larger Saturn image was made with a C11 plus 3x Barlow

Good conditions in Normandy during the opposition. Rings brigthness was evident, specially in visual observation.

SATURN IMAGE, JANUARY 13th, 2005. 22:26 UTC.
9.25" (23.5 cm) Celestron SCT @ f/39.5
ATK-1HS CCD camera + RGB filters.
Seeing excellent (Pickering 8-9.) Later deteriorated somewhat.
Transparency very good (5.5mag) occ clouds.  Wind SW (0-5mph.) Later calm.
Eq Diam=20.5"  Altitude=56 degs.


Here is the full seqeuence of images from opposition night.
SOme vague streaks in the equatorial zone, and a white spot in the mid-SEB zone are present, but little else, hence no animation is attached (over 1MB.)

David Tyler and Myself decided to collaborate for a joint Saturn image since we were both imaging on the night of opposition under excellent seeing.
Youll find the attached image of our joint effort. David sent me his raw data which i processed, and added to my own. Here is how it was made:
Celestron 11" and 9.25" SCTs both @ F/39.5.
Both using ATK-1HS II CCDs.
Both using True Technology type II RGB filter set.
2005/01/13. 22:10-22:25 UTC time window.
Approx 9500 images for luminance image.
This must be the first time two amatuer telescopes were used to produce a high resolution image. These methods certainly have benefits, especially for filtered imaging.
Best Wishes
Original picture


One last effort from opposition night.
This time, processed rather differently to give a more true rendition of the colour bands present, and also a lighter processing for the most natural appearance.
I prefer this result to the original i think which shows the colour tones/view i saw visually.

Sorry for the late but on this period I never had time to process any recent Saturn image.
Here I send a just fair image taken at opposition.
