It’s so interesting to disassemble a telescope especially those have a very precise and big gears. I’ve disassembled my computer since I was 8 and 8 years later I disassembled my LX90. I will tell you how to do so step-by-step. However, take it at your own risk, I will not responsible for any damage done to the telescope. I suggest that you read all the procedures before you do anything. If possible, read one more before you start and it’s advisable to print this article with you or leave your monitor on when you are doing your work.
The camera on Mars Reconnaissance Orbiter (MRO) captured its first light of Mars in the mapping orbit, thus the high resolution image is obtained.
The image is acquired by High Resolution Imaging Science Experiment (HiRISE) acquired at 8:16 PM. The image scale is 29.7 centimeters per pixel. At this moment, the spacecraft was at the altitude of 280 kilometers. To be more accurate, at this resolution, a people is visible in the image.
My friend March05 has contributed very much this time. He has done the lunar eclipse sequence photo. Credits to him! The photo above was taken by his lovely Casio EX-Z750.
What about mine? I still have to adjust some of their brightness and crop them out. It’s quite time consuming.
Oh yeah! I just received my copy of Sky & Telescope magazine directly shipped from US this morning! This is my first magazine subscribed from US as well as my first Astronomy magazine. Not to mention that the contents are really good; however, the advertisements are just too many that I can see them most of the time. Nevertheless, they are quite informative as I know more about the astronomical instruments after reading them. Credits to all the editors!
Don’t you feel that this photo is nice? I used my home garden as the background in this photo. I like it so much!
This articles is supposed to be posted yesterday night but when I online today, I just found that this is still in the drafts. There must be something happened to my internet connection. Anyway, it’s here now.
Continuing the Pros and Cons of DSLR Astrophotography, Pros and Cons of CCD Imager is here. The chip of the DSLR is not as great as the specially designed CCD imager’s chip. Let’s look at its speciality!
Cooling system
Operating the imager under low temperature allows you to easily capture a library of fixed-temperature dark frames always needed in serious astrophotography.

Noise is also significantly reduced becaused of the low temperature. There is a form of cooling called TEP (Thermo-Electric Power) fixing the temperature at a certain degree kevin. This is the best cooling system ever used.
I’m sure that some of your know what does DSLR stands for. It’s Digital Single Lens Reflex. Let’s straight into the topic this time.
Dual Use
As you see from the left image, DSLR is just like a conventional camera. Therefore, it’s able to take both your family’s photos and astrophotographs. It’s more valuable!
This farthest galaxy cluster observed from Earth is discovered by astronomers from the U.S., Europe and Chile.
Almost 10 billion light-years from Earth, cluster XMM-XCS 2215-1734 contains hundreds of galaxies surrounded by hot X-ray-emitting gas. The existence of the cluster so early in the history of the universe challenges ideas about how galaxies formed, said lead author Adam Stanford, a research scientist at UC Davis and the Lawrence Livermore National Laboratory.
