THE MOON

The Moon is one of my favourite photography object. Photographing the Moon at focal length less than 1000mm is quite easy. However, high resolution and magnification images of the Moon is very hard to achieve.
You'll need to have a very steady mount. The reason is that the exposure for photographing the Moon at high magnification runs into seconds, usually about 3 or 5 sec on ASA400 film. The most common reason for unable to achieve good print of the Moon is vibration during exposure and sometimes it came out as under or over expose.
However, recently, I was able to take countless high quality images of the Moon. The reason lies in the CCD which I had acquired few month ago.
My CCD camera is originally a security camera. The detector is a 1/2 inch CCD chip which has a sensitivity of 0.03lux. That's pretty impressive since most CCD in camcoder is about 3lux. And we can't use camcoder because it's heavy.
For imaging, the CCD is connected to my computer via a video capture card. The card have an input for video signal. The image on the PC screen is of real time. Whenever, the condition is good, I will save the image as either bmp or other format.
The raw images is seldom impressive. Enhancing the images is done using Adobe Photoshop. I was very thrill is the images so far. However, the CCD can only capture images of bright object, ie the Moon, Jupiter, Saturn, Venus and stars down to magnitude 7 or 8.
Check out the images yourself. What do you think?

This image of the Moon is taken on 20th April 1998. The time is about 6am local time.
Since the CCD field of view is small, I have to take about 12 images to cover the whole Moon. Then I joined them together using Adobe Photoshop. The actual images are in B&W but I added some colour to make it more realistic.

This is another view of the Moon. It was taken about one day after the first quarter, a couple of weeks before the previous image was taken.



Here is some example of how the individual images look like.

Here is some of the more famous crater of the Moon at high resolution.
