Seeing = 7/10 Trans.= 3/6
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
Obs.site : Mozuhonmachi Sakai-City Osaka Japan
Exposure : 1/3 sec
Analog gain: 6dB
Image Processing;
Enhanced images;
The Maximum Entropy Method deconvolution after composite of the original taking images.
Blue channel imagess;
Only composite of the original taking images without any spatial images prosessing

Remark;
Good seeing.
SEBn and EZs become darker in Blue light.
So The color of EZs seems to change from white to yellow.
Remark(Japanese);
シーイング良好
SEBn とEZs が青色光で見ると暗くなってきている。
そのため、EZsの色が白から黄色に変化しているように思える。
