Visiting the BBSO at Big Bear, California / USA

I have been privileged to visit the world biggest solar observatory during my holiday to my friends in Big Bear, California. Thank you very much to Professor Wenda Cao for its kindness and explanation during the tour. Thank you also to Dr Phil Goode for having forwarded my email to Wenda.

PixInsight training in Besançon / France

BB, Feb 05 2017, No. 192-squashed

3 days training on PixInsight software given by the AIP (Astro Image Processing) group.

Astro-Image-Processing Training, St-Luc (Switzerland)

Astro-Image-Processing training dedicated to Nightscapes and Timelaps with Jean-Luc Dauvergne (Scientific Journalist specialized in Astronomy) and Stéphane Vetter. This training took place at the OFXB observatory in St-Luc, Switzerland.


Exceptional encounter with NASA Astronaut Edgar Mitchell

I have been invited to a special conference by a colleague of mine. Thank to Raphaël Domjan (the guy who made the first around the world with solar energy PlanetSolar), I had the possibility to personally meet NASA Astronaut Edgar Mitchell (Lunar Module pilot of Apollo 14).
A privileged encounter with NASA Astronaut Edgar Mitchell, who walked on the surface of the Moon in 1971 during the Apollo 14 mission.

Astro-Image-Processing Training, La Grande Garenne (France)

A special training dedicated to Solar/Lunar/Planetary imaging. A lot of new tips learned thanks to our teachers Thierry Legault, Christian Viladrich and Jean-Baptiste Grillet.

We also planned a visit to the Nançay Radio Telescope.

New Skin for the SoldatiSpace Observatory Website

After a very long period since the last post, it was time for a come back. So you will find the SoldatiSpace Observatory Website in a new look. Some technical features have been added. The new website will now automatically adapt the content to the size of your screen. That will increase the ease of navigation when looking with a smartphone. Hope you will enjoy! Thank you for looking!

NEAIC and NEAF 2010 in New York


AIP in Saint Michel l'Observatiore

After this Astro Imaging Processing convention, I developed a technic to minimize the gradient on astronomical images. A link will be available soon.

Space Shuttle in Washington DC

On the way home from the NEAIC and NEAF in New York, I missed my connecting flight in Washington DC. That gave me the opportunity to see the Enterprise Space Shuttle (Officially called the Space Transportation System or STS). The only place in the world where a true Space Shuttle is exposed.


NEAF 2009, New York

The main purpose going to the NEAF was to meet some “famous names” that we hear on the internet and see on the Astro-magazine. Here are posted some images.

A must to see on his website.

NEAIC 2009, New York

To celebrate the International Year of Astronomy, I went to New York for the North East Astro Imaging Conference. Here are some photographs.

AIP Convention in Paris

Last week-end I went in Paris for the AIP (Astro Images Processing) convention. It has been a good opportunity to improve my knowledge in images processing and to meet some of the best astrophotographers like Thierry Legault, Eric Mouquet, Laurent Bernasconi, Franck Bugnet, Nicolas Outters and others...

I would like to thank Olivier for his car-sharing. That gave me the opportunity to meet an another guy who is working with refractors and Mac’s. Thank you Olivier!

I also want to thank the AIP comity for all the volunteer job they did to organize this very helpful processing training convention.


SoldatiSpace Weater Station

Since beginning October, the observatory is equipped with a near research grade Weather Station. This equipment allowed to register and monitor: Temperature, Humidity, Barometric pressure, Rain, Wind speed and direction, Solar radiation and UV index.


My Astro-Physics mount PE curve

I recently measured the Periodic Error accuracy of my Astro-Physics mount with PEMPro. The data recorded shows an extremely high accuracy of 2.0 Arc-sec. peak to peak without PEM. The PE curve has been downloaded into the mount for the PE management. The PEM aloud me to capture images with an exposure of many minutes without auto-guiding!

I asked the author of PEMPro, Ray Gralak , (from San Jose, California) to confirm the reliability of my measurement. This is his answer:

“Hi Nicolas,

I looked at your data and it shows 2.0 arc-secs peak-peak, with an RMS of 0.334 arc-secs with quadratic curve fitting. The very low RMS indicates that the certainty is very high that the PE is actually 2.0 arc-secs.”



First Light With the ProLine Camera

The sky was not perfect but I finally had the opportunity to test my FLI ProLine camera. This picture is the first I took with it. I am pretty satisfied about what came out even if I need some more experience. I am looking forward for the next target...


Partial Solar Eclipse

We had a cloudy day for the partial eclipse. I hope that the friends who went to China for the Total Eclipse had a clearer sky! Anyway, I still could take some pictures trough the clouds during the maximum phase. They have been captured with a Nikon D300 on the prime focus of the observatory Zeiss APQ 150/1200 refractor.

This picture has been published on the swiss radio and swiss television website.


Lars Carlém's visit

While visiting his daughter in Switzerland, Lars noticed the observatory’s dome. That made him curious since he has been an active member of the Tycho Brahe Society's observatory, Sweden. He had the nice idea to deposit a letter in the mailbox of my parent's home explaining his interest for a visit. We scheduled that on saturday. Unfortunately the telescope was disassembled for a repair but we could still observe the sun in the Ha light through the Coronado filter. You are always very welcome Lars. I am looking forward for your next visit.
