Have you ever wondered if there was a complete and recent book for observing and imaging planets? … Now there will be one!
In 2015 me and six skillful amateurs published a book that has won a great success in France (… and even outside France!): Astronomie Planétaire. I am delighted to announce that it’s going to be translated into english so more people will be able to read it! Click on the image to learn more:
The book is a comprehensive study of the whole perimeter of planetary astronomy:
- Learning how to use equipment (telescopes, cameras, filters…)
- Learning how to use softwares (alignment and stacking, wavelets, derotation…)
- Learning how to identify activity observable on planets
- Learning how to analyse the data and even participate to science projects!
Planetary Astronomy will be published by AXILONE. More to come later!
Getting ready for the arrival of the JUNO spacecraft in orbit around Jupiter, a workshop was held this month in Nice, France, around scientists and amateurs from various countries in the world. High quality informations now available for everyone!
Some thirty astronomers from the entire world met for this two-days workshop […] Continue Reading…
I’m beginning a serie of articles dedicated to this little imaging bomb that is the ASI224MC camera from ZWO. It’s quite different from the PLA-Mx that I have been using this past years, first because of its pixel size… Let’s take things by the beginning: the setting of the […] Continue Reading…
In 2016, a major event in the Solar system exploration is going to take place: the arrival of a new space proble around Jupiter : JUNO. This should take place during the summer of 2016 and it will be the first since the Galileo orbiter (1996-2003). Scientists ask amateurs for […] Continue Reading…
After the mediocre to fair nights described in (1) and (2), here are my observations during the next two following nights (August 31th to September 1st and 1st to 2nd). Those two nights have been somewhat cloudy, but with a much better seeing. Meteorological conditions had changed too !
During […] Continue Reading…
After a general review of the AstroQueyras observatory context, here are some of my notes related to the observed weather and night sky quality during my stay. On the first two nights (August 29/30 and 30/31) the sky was clear but seeing was quite mediocre. I have note a particular […] Continue Reading…
AstroQueyras is an observatory located at an altitude of 2930 meters in the deep french Alpes mountains, very close to the italian border. It welcomes one-week amateur missions as well as one-night public stays. It’s equiped with a 620 mm F/15 Cassegrain, a 500 mm F/8 Ritchey-Chrétien and a 200 mm […] Continue Reading…
During the 2012 and 2014 apparitions of mars, we talked a lot about a very curious detail imaged by several amateurs: an object projected beyond the terminator, that could only be at a very high altitude. Seven scientists and six amateurs co-sign this month a paper about it in […] Continue Reading…
In my last article Jupiter under the jet-stream, what’s the result? I described the effect of one the worst meteorological conditions for the seeing. During my last observing night of January 17th, images were noticeably better (although still not really good…). It is possible to find explanations?
Here are some Jupiter images […] Continue Reading…
Last year I made a summary on the best conditions for a good seeing. Unfortunately there are as well other conditions that damage it. Here is a “good” example on Jupiter: the influence of the jet-stream.
What is the jetstream?
The jet-stream is a very narrow, but very fast, stream of […] Continue Reading…
