1 min. exposure, 2009-09-12 UT 22:24, 12" SCT  f-7 + CCD ST10XME
11.85 mag, coma: 7'12", tail: 8' in PA 40°


The comet is now changing to the morning sky and not easy to photograph.

Because my flagship ST10XME is out of order till now, my wife Wen and I took this image with our Canon EOS350D out of desperation on New Year's Eve.
The image is not bad for this snapshot camera, the colors were easily to adjust and the magnitude limit is 16 mag at least.
You can compare the picture with the image of Pepe Manteca from December, 23.

The ST-2000XCM Color ccd camera of SBIG provides color images with very short exposure times.
Pepe Manteca from Spain took this amazing image at December,23 2008. The colors are very similiar like images with ST10XME and CFW8 filter wheel.

No Moon was disturbing the photography, but a moderate South-East wind effected some blurring on the image.
Although the skies were really clear, I remarked a decrease of the magnitude since seven days.

Today the 70% Moon was a little challenge, but the very clear wheather offered superb deep sky conditions.
Also I used another focal length for the exposure as usual. In combination with my old Lumicon Giant Easy Guider the LX200 can be reduced to f-7.0.

Some chainging wheather conditions forced me to start several times a new sequence of images of this nice comet. Finally I am happy for my patience...

At this night I tried out a RGB image of the comet. The comet is just passing a rich star area in the winter milky way in constellation Chepheus. The red background colour comes from the millions of faint stars on the image. Some yellow stars are also remarcable, they have good red and green,  but almost no blue colour.

At November, 27 2008 I took a series of 50 images, 3 minutes each. So you can see very different views of the comet of this magnificent night.
