コメント:昨日に比べてシーイングが少し改善された。
自転に伴う目立った模様は見えない。
拡大率を変えてみた。もうしばらく、拡大率は試行錯誤
してみようと思っている。

処理が遅れてしまいました。SEBにはいくつか白斑があるようです。後日動画も作りたいがいまは余裕がありません。極地方のエッジが不規則に見え、その外側のSSSTZは依然として赤みが強いです。
南極の中央部1/2程が1ヶ月程前(1月28日頃)に比べ色合いが白っぽく(うすく)なっているように見えますが、なにか変化があったのでしょうか。

土星の動画ですが、SEBには白斑がかなりあり活動も盛んな様子です。南極周囲のSSSTZにもなにかありそうですが画像処理に伴うもののようにも思いはっきりとは判断出来ません。

I have attached a set of images taken on the 4th and 6th of March.
The same set of filtered images were taken each night, the difference
being that a colour image from the ToUcam was taken to compare to the RGB
image constructed from the filtered monochrome images.  There is also a
false colour image each night created from the Methane/IR/UV data.

Seeing on the 4th was average (5/10), and started of good on the 6th (7/10)
but it dropped off soon after I started and became clouded out within an
hour of starting to image.  Temperatures on the 4th were around -15C and
-2C on the 6th (hence the steadier seeing).

Image details are listed below:

Telescope:     30cm SCT @ f28
Camera:        ATK-1HS, 320 x 240 mode
Filters:          Luminance - Schuler Clear w/IR Rejection, 30 sec @ 20fps
Red - Schuler Red, 30 sec @ 20fps
Green - composite from Red/Blue data
Blue - Schuler Blue, 30 sec @ 20fps
IR - Schuler IR Pass 830nm cut-on, 60 sec @ 5fps
Methane - Custom Scientific 889nm, 18nm FWHM, 50 x 3 sec
UV - Schuler UV 340nm, 50 x 3 sec
Image Capture via K3CCD Tools
Image Processing via Registax 3.0

I have had some problems with the main computer in the observatory during
the last week, and have had to shorten the length of video capture time and
the frame rate.  I expect to get back to capturing longer sequences
especially for the narrow band images which could use more data to build the images.

Please let me know if you have any questions
