An other example of turbulence management. It works really well.

Hello,

i have decided to explain things about JetsonSky so i started with my first spoken video : Where does come from ?

 

For now, it is French spoken with English subtitles.

 

https://youtu.be/D51...?feature=shared

 

I will make at least 3 more videos :

 

- JetsonSky functions with a camera plugged
- examples of treatments with Moon and planetary videos
- examples of treatments with deep sky videos

 

If things goes well and if people are interested in thoses videos, i will try to make some English spoken videos. This will be quite funny and rock 'n roll i guess.

Wow, that turbulence stabilization is crazy good. Nice work! 

[easybob95]

Many thx Taylor.

Hello,

2nd video about JetsonSky : the functions

 

It explains the main functions of the software. In French with English subtitles.

 

https://youtu.be/8Z-...?feature=shared

 

Still 2 more videos to come.

Hello,

 

3rd video about JetsonSky : exercises on Moon and Jupiter videos

 

In French with English subtitles.

Hello,

 

4th and last video about JetsonSky : exercises with deep sky videos.

 

French spoken and English subtitles.

 

https://youtu.be/PQY...?feature=shared

 

Quite long videos but i wanted to explain how JetsonSky works. Very few will look at them but i hope those videos will inspire the few.

Hello,

 

still using JetsonSky with a picture of the Moon this time to enhance colors of the Moon's soils while preserving details and sharpness of the image :

I think there is no equivalent result anywhere else.

Hello,

 

some tests yesterday. The sky was not bad.

 

I used the 7 Artisans 35mm F0.95 lens with an IR cut filter. Not bad but i bit disappointed. Not a really great lens. My old Canon FD 50mm F1.4 gets better optics. It is the problem with optical system. Most of time not bad but not good.

 

The video :

Awesome. If ever you set up a company selling live feeds into a VR headset, I will be your first customer.

Quite a good idea !

Hello,

 

i decided to make some Moon craters detection with JetsonSky.

 

I used YOLOv8L to train my crater dataset.

 

Here is a test video :

 

https://youtu.be/nFu...?feature=shared

 

If i consider i trained the model with only 300 images, the results are not bad.

 

To get something more serious, i would need 10 times more images but training the model would be a bit long (with my RTX4080 laptop GPU, it needs 2 hours to train the model with 300 train images).

Hi,

 

i made a model to detect satellites (and planes & shooting stars but for them, i get not enough data to make something reliable).

 

So, i trained my model with YOLOv8n.

 

here is a video about satellites detection.

 

I show the RAW video, the preprocessing and 2 detection method :
- my old OpenCV simple blob detection method
- the YOLOv8n based model to detect satellites

 

https://youtu.be/H_SVnOut2zM

 

The result is interesting.

Hello,

 

i have released on Github some small programs to allow you to test some of my basics functions i use in JetsonSky.

 

You will need some specific hardware (NVidia GPU) and specific software (Python, CUDA SDK, numpy, opncv, cupy).

Oh the satellite tracking is very cool. Love following your progress on this project.

Many thanks klangwolke.

extremely impressive! I'm hoping to setup a basic rig to do some testing on at some stage, really great work

[easybob95]

JetsonSky can also manage gradient (or vignetting).

 

An example of video gradient removal (in fact light pollution) :

That is really cool, thanks for sharing! I feel CUDA will be a big player for lucky imaging in the future

[easybob95]

For fast treatments, CUDA will be a must have. Parallel computing with GPU or at least multi threading computing on multiple cores will bring fast treatments for heavy calculations. This will bring improvement camera sensors can't bring now, considering sensors don't bring new interesting things for years.

Hello,

 

JetsonSky is back on Github (V50_15RC) and free to use for non commercial and personal use only. For any other kind of use, please ask me before.

 

https://github.com/A...illou/JETSONSKY

 

This version is supposed to run with Linux and Windows systems. I must say i made very few tests with Linux version & AGX Orin. It seems to work but it is really slow comparing to Windows version. Keyboard management seems to work but i must say i am not pleased with pynput. I don’t have a better solution for now.

 

I guess Windows system will bring better experience with JetsonSky.

 

Alain

[easybob95]

i have uploaded a new version of JetsonSky on Github : V50_17RC.

 

Some bugs removed and i have added the ability of managing AZERTY or QWERTY keyboards, considering the functions we access with the keyboard.

 

I recommend you to read the up to date documentation i have also uploaded on Github :

Hi,

 

a small test yesterday, despite the clouds (but no choice, i had to deal with them).

Hello,

 

a daylight video with JetsonSky to see 8 bits VS 16 bits captures to retrieve very small signal in a live video (EAA capture) :

Alain

[easybob95]

Hello,

 

i made an other test to compare 8 VS 16 bits captures. This time, it is outdoor at night but still no deep sky because of the weather.

 

I hope 16 bits capture will bring many things with DSO targets.
