36 frames composite
Comment-
I got about 300 shots.
I made 9 pictures from those pictures by composite processing.
But, I could not find a thing which moves with rotation of Saturn.
So, I did composite of 36 better frames which I got for 40 minutes, and I made one picture.
That rotates for 40 minutes about 24 degrees.
From this picture,I often appreciate a condition whereby the surroundings of the South Pole become red.
Comment(Japanese)-
約３００コマ撮影しました。
ここからコンポジットして９コマの画像を作りましたが、自転に伴って移動するものは見つかりませんでした。
それで、４０分間で、良さそうな３６コマからコンポジットしてみました。
４０分間に、約２４゜自転します。
この画像から南極の周りが赤くなっているのがよくわかります。

All images are taken with ;-
Telescope : C11 (SC) D=280mm fl=2800mm
Camera :Minolta DimageEx1500 Digital Camera taking lens removed
Effective F No.: 25 (XP24mm Eyepiece Projection)
Filter: IR cut & Low-pass built-in the camera

Image Processing;-
the Maximum Entropy Method deconvolution after composite of the original taking images (the left images)
Enhanced the bright area of the Saturn to indicate the datail of EZ (the right images).
Remarks;-
Some active area was seen SEBn and EZs at CM = 110 - 120 deg.
