C'est un outil de traitement d'images pour l'astronomie, capable de convertir, pré-traiter, d'aligner manuellement ou automatiquement, d'empiler et d'améliorer le rendu final d'une séquence d'images.

You can actually see protoplanetary disks here: disks of dense gas surrounding stars that have basically just been formed!A quick reminder for those interested in playing around with the latest AutoStakkert!2 lucky imaging software: there is a beta version of AutoStakkert!2 available at the The versions displayed on that site have not been tested a lot, but it generally works quite well and has interesting functionality such as:And of course, all of these nicely hidden from view (but easily available) so if you just want an easy to use, fast and high quality lucky imaging stacking program, it is still there.If you find any problems with a beta, please let me know so I can fix them. Luckily, accurately determining offset in images is no problem at all for AutoStakkert!2. Anyway, here is the first part of the rather long story that will probably be completed in a year from now…I did not want to go outside, because I had to get up early the next morning and was already tired. At the moment I seem to be very interested in getting the best performance out of AS!2, without a decrease in image quality of course. Post-processing with Photoshop and WinJUPOS, to derotate the stacks.Occasionally, I’m going to use this blog to show some of the images I made. (AS!3, AS!2) is lucky imaging software used to automatically analyze, align, and stack images of the Sun, Moon and Planets that were taken through a telescope. But if you have a lot of slightly different and under-sampled versions of those pixels, then you can significantly increase the resolution of your images! However, if you can decrease the total processing time a lot, you could for example process more recordings in the same time, or experiment on the same recording to find better stacking parameters that will actually end up improving the image quality. Je hais les spams : votre adresse email ne sera jamais cédée ni revendue. Dans cette vidéo, ... l’utilisation de logiciels de traitement d’images est presque obligatoire si on veut obtenir un résultat plus fin et détaillé. Whenever there is an opportunity to observe the night sky, you take it, even if you don’t really want to. Une fois téléchargés, certains seront même directement exécutables sur votre ordinateur, c’est-à-dire que vous n’aurez même pas besoin de les installer. )A couple of nights ago I was lucky enough to have some decent seeing conditions to image Jupiter. But it does take forever though. Vous pouvez vous désabonner à tout instant.Bienvenue sur Les Curieux du Cosmos ! Super Resolution does indeed give you super resolution.AutoStakkert!2 uses an advanced technique called drizzling – officially known as Variable Pixel Linear Reconstruction – which was originally developed for the hubble telescope to achieve sharper results for undersampled images. I don’t know if I can fix it, but I certainly can’t fix what I don’t know.We are interested in trying out your software and wondered if there is an End User License that we can look at before proceeding.

A new beta version shall be released soon, including support for better spectral stacking, direct reading of all avi files if you have the appropriate avi codec installed, etc etc.Well, it is indeed impossible if you only had those few pixels to work with, but if you have more than one image of the same target, either from slightly different viewpoints or taken over time with a slight offset in the images, it turns out it actually is possible. Voyager 4.5 est le logiciel d'astronomie permettant la meilleure expérience utilisateur. Stellarium est un logiciel qui vous permet d'observer les merveilles du ciel. And then I noticed Orion, and in particular the fuzzy spot at the center of three stars making up the sword of the Hunter, close to the larger structure of the three stars making up its belt. Stacking monochrome* images is more than twice as fast, and performing surface alignment received a speed boost of about 30%.Now it is back to the boring list of other to-do’s…* I still need to have a look at the color stacking code (and drizzling), but I don’t think there is a lot of performance to be gained there.Around the end of August I’ll release a new version of AS!2, featuring some bug fixes and of course new features so I can find more bugs in the following months.
Alors je dis ça parce que, si vous prenez la Lune au smartphone par exemple, au travers l’oculaire de votre instrument, vous ne prendrez certainement pas le temps de vous embêter avec la partie traitement.

Much better than anything I had soon during the past months, if you only see poor seeing you quickly forget what decent seeing looks like. Of course, it does not come close to what Unfortunately, this is where the story ends for now. Today I will discuss an image of M42 that I made over a year ago on the night of November 18-19 2012. Tomorrow I was going to be tired.I pretty much never look through the telescope myself, but let a camera do that for me. I’m currently using 2.3.0.8 myself without any problems, but small updates are frequently performed that might brake or – preferably – improve the software further.O, and keep an eye on this blog, because I haven’t been sitting still lately!

I planned to post this story soon after the images were taken, but for some reason that never happened….
