One of the most important things before an astrophotography session is planning. You can never go out shooting with your camera without being well prepared in advance. There is something however, that you can never predict – weather!
So here comes my critisism towards SMHI (Metereological Institute of Sweden).
There is no weather website that turns ou to be wrong 9 times out 10 than SMHI (http://www.smhi.se). I am totally disapointed by their forecasts for the weather in Scandinavia. And because of our unpredictable and hard mistaken summers in Sweden it is most crucial you get at least the forecast right. Not to forget about their lousy website and the services that demand a fee in order to subscribe e-mail or link their reprehensible forecast through a flash application which has large limitations and is badly designed.
Contrary to this primitive and lousy website you have the Norwegians who’ve made an effort in forecasting, website layout and usability. It is one of the best I’ve seen so far (conserning weather forecasts in Scandinavia). This is the page I’m sticking with from now on. http://www.yr.no
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.
