Hi all,



It's been a long time that I've not shared with you datas from Pic du Midi.
So here is the last image obtained by François Colas and Thierry Legault. I've just made the processing.

2020-11-01-2205_0-244_lapl4_ap226-ASCN.jpg

With other datas that they made previously in the month with other friends, I've been abble to make a global map. It's realy rare to have enough data to achive this ultimate goal.

I was not expecting that much from this opposition. I've observed as much as possible at home with my Mewlon 300 but I don't have enough images to do that because of the bad weather in october (no data at all this month !).

And of course, once you have such a map you can put it back on a shpere to make it rotate.

Thierry Legault made a 3D animation with this map.
Here it's visible in cross-eyed vision

And here in parallel vision.

Enjoy.

Good team effort Jean. What does s2p, imcce, omp, image optic stand for?

It must be really pleasing to work with data with so much image scale and detail - well done

 

Also do you realise this is not the imaging forum? This is the observing forum - cloudy nights change the names  some time ago!

This is what you are looking for - Major & Minor Planetary Imaging wink.png

S2P is Station de Planétologie des Pyrénées. IMCCE is a laboratory of Paris Observatory, OMP is Observatoire Midi-Pyrénées, and Imagine Optic develop an adaptive optic that we have tested during some of the observations. 

I did not realized that I'm not in the proper part of the forum no. I did not knew this change. May be that the owner of the forum cam moove this topic ?

Moderation:

Although it is an image, we are discussing it in terms of the map and observing, not in terms of image acquisition or imaging technique.  It a fine discussion in this forum.  Observing is not limited to the image through the eyepiece...

 

Jaimo!

         I thought that was a Hubble pic myself when I saw it. In fact, I've seen Hubble Mars images that are of lesser quality than this one. Just... WOW!bow.gif

That is absolutely jaw-dropping! So great to see images from the historic observatory and telescope, done by superb observers and imagers. Thank you for sharing!

P.S. - any chance for you to get on the 2-m telescope? Sedna needs a map ... ;)

Thank you for the comment :) The 2 meter is not as good for planetary imaging ;)

           You sure? Because we only got one good image of Phoebe as Cassini went by on its way to Saturn proper. It needs a Map as well! LOL

 

  Clear Skies,

Thanks, will use your map in WinJUPOS.

 

I think your images are even better that HST images!

Jean are you able to explain in more detail about the adaptive optics - how the light is being corrected?

Yes, the wavefront is analysed with a Schack Hartmann (very classical methode) and it's corrected with a deformable miror. That's also very classical. The inovation here is to make a analyse of the wafefront directly with the image of the planet rather than a star. 
It's not 100% efficient yet but we work on it.

I saw your Mars 3D simulation on Spaceweather.com 2 days ago. It was one of the best cross-eyed 3D images I have seen, and the fact that it is a video showing the planet in rotation was amazing!  Thanks!

J-Luc, I'm shocked, I absolutely agree this is the very best image of Mars from Earthbow.gif  Pic Du Midi is not far from me, I need to visit one day...

 

Luckly your observation has been done before the new dust stormwink.gif

 

Calar Alto in south of spain has a 1 meter telescope available for "amatour" astronomers, did you never thought to try it?

 

From that location Jupiter and Saturn will be a little bit higher in the sky next yeargrin.gif

 

Thanks for sharing!

Congratulations on this wonderful map.

 

I spent a fabulous day some decades ago visiting the Pic du Midi observatory. Apart from the telescopes I remember Apollo butterflies feeding on thistle flowers nearby. There were even eagles soaring high overhead.  David

Absolutely superb. 

 

This opposition was favorable for a lot of people.....except me of course.  Don't think I got one night of average seeing but oh well.
