Last night I finally received my Celestron cam! After some adventures between Amazon.com, my bank and VISA, because of warranty & delivering issues towards me as a European customer it’s finally in my hands. I’m eager to start working with this camera as soon as possible whenever weather circumstances allow me.
The installation worked smoothly on my Windows XP service pack 3 for both my PC and the laptop. This cam is used to record a planetary object such the sun, moon or the planets. The software that follows with the camera assists you to filter out blured and badly exposed images due to atmospheric conditions. I’m giving you a couple of examples on the results below.

Be aware of the sound:
It was almost full moon (-1 day) and I was in big hurry to get a few shots of the moon surface before fog and clouds would set an end to this observing session. The results of this session were not up to my expectations but I hope for a cloudless and clear night for next time. The individual exposures were quite good considering the fog and small clouds that passed before the moon from time to time.
On the southern hemisphere of the moon you clearly see the Tycho crater named after Tycho Brahe, a Danish astronomer from the mid 15th century. It got a high albedo and the impact resulted in a crater which is quite recent in astronomical terms (108 million years ago). Samples from this crater were collected during the Apollo 17 mission which was the last manned mission to the moon.
Apollo 17 was unique in its way, partly because the first scientist (Harrison Schmitt) was onboard on a mission to land on another celestial object and also because of the lengthy moon-walks. The goal was to gather as many samples from soil and stones as possible.
One of the questions that often arise is, how is it possible that the moon is battered by so many impact craters while the earth does not reveal such landscapes? Scientists have come to the conclusion that earth does not look the same due to erosion and atmospherical and geological activities.
Today it is known that the moon had volcanic activity and also that the existence of the moon was a result of a great impact by another large celestial body that crashed into the proto-earth. This is proven by the fact that the moon and the earth share the same basic geological structure according to the samples gathered from moon’s surface during the Apollo space missions!
Sara and myself where about to walk to the grocery store when I asked her if by any chance it would be possible to spend this evening with an observing session. I wouldn’t normally have asked her if it wasn’t because it was our last night together before she would go visit some relatives in Stockholm for a week.
Around 10 pm I started carrying out the mount, tube, camera and all other instruments needed. It was about time to set mt sights toward Jupiter. A planet that fascinates everyone that knows a little about it. Apart from it’s size and beautiful colors few people think how important this gas giant has been for our lives and our very existense! Yes… Because Jupiter has acted as saviour for this pale blue dot (C. Sagan) many times. The gigantic gravitational field pulls all the garbage floating around there in the outer solar system towards Jupiter. In fact, Jupiter’s role is as big as the one assigned to our Sun.
Polar alignment kept me busy for the most part, even though a DLSR camera wouldn’t give the same results as a CCD webcam, and the only webcam I own is a CMOS one. Nevertheless, the result you see below and thanks to Sara we could enhance the colors pretty well. So the result of Jupiter with my EOS 300D Digital Rebel was actually good!
And it was time again to turn the telescope toward the closest star we know. The Sun. And this dwarf star is also the most fascinating! It shows us how other stars work, considering fusion, magnetic fields, solar winds and all other kinds of phenomena making scientists drop their jaws. He still surprises us to a moment of silence during the ending of the 11-year cycle to the moment of violence. “Here I am, and I am alive!”.
It felt like some sort of an instict to bring out my telescope that day without checking spaceweather.com. To my astonishment I saw two solar spots emerging to the southeast on the visible side and the photo to the left is the result. Unfortunately some hot spots appeared and I forgot to handle it.
The following image is an enlargement of the previous one.
