Happy New Year to everyone and Merry Armenian Christmas (January 6th) to all my Armenian friends.
On January 3rd, as the sun set, I noticed in the navy blue sky, that a thin crescent moon was visible in the sky. Therefore, I decided to take my telescope out and take images of the moon.
For Christmas, I got nice additions to my telescope: a new T-Ring and T-adapter for use with DSLR cameras. Therefore, I decided to take the photos using my brother’s DSLR camera, which was a Canon EOS D60.
I took my telescope out in the bitter cold night at -16 degrees celsus, and quickly got it set up aligning it to the crescent moon. Looking at the crescent moon, I saw a small portion of a mare, and many craters on the lower part of the crescent. It was beautiful. Since I was using a DSLR camera, I could take long exposure images, which I could not do using my CCD imager. With that feature, I have the ability to obtain different kinds of pictures of the different bodies of the solar system. I quickly went about taking the photo.
I experimented with the exposure setting, and tried to figure out how to eliminate the wobble that I created by pressing the shutter button. Eventually, I found the right setting for the image and captured a fair number of images of the moon. The moon captured in my images were two second exposure photos with the other settings set to auto. It showed the lit portion of the moon completely white due to the collection of light from the moon, and the dark portion dimly lit. The reason that happened is because the Earth also reflects the sunlight that it receives from the Sun. The reflected sunlight travels to all different directions, and a certain amount of the sunlight hits the moon. This phenomenon is called Planetshine, and it creates this photographic phenomenon called, “The Old Moon in the New Moon’s Cradle.” It is a unique sight for those who know how to find and capture it.
Below is a comparison of the crescent moon and the Old Moon in the New Moon’s Cradle.

After the Moon set below a row of houses, out of my sight, I decided to focus my attention on Jupiter. It would be reaching opposition the next day, which means it would begin moving backwards relative to the Celestial Sphere, it orbits closest to the Earth, which makes it seem closer than it actually is, and it is visible all night, much like a Full Moon. Since the next day was predicted to be cloudy, I decided to look at it now.
Looking at Jupiter through the DSLR camera was a different (no, difficult!) experience than through the eye piece. Jupiter looked quite over-exposed. Any attempt to take a long exposure image of Jupiter failed as the camera wobbled too much and my telescope tracking feature was not doing a good job at keeping the image still. I didn’t have enough technique to take a good image at that time.
As a result, I decided to pack it in for the night. I took all my equipment inside and got warm by the fire. It would usually be over for the night, but the sky was still clear, and I felt the need to take my telescope out once more. Therefore, I did just that.
