Electronically Assisted Astronomy with a Jetson Nano

Hello,

it is time to make a brief summary about JetsonSky install.

JetsonSky can be found here :

Now, JetsonSky can manage :

  • camera (ZWO)

    ASI178MC, ASI178MM, ASI178MM Pro
    ASI224MC
    ASI290MC, ASI290MM
    ASI294MC, ASI294MM, ASI294MC Pro, ASI294MM Pro
    ASI385MC
    ASI462MC
    ASI482MC
    ASI485MC, ASI585MC
    ASI662MC
    ASI678MC
    ASI1600MC, ASI1600MM

  • videos

  • images

You will find in this repository :
JetsonSky_V40_18RC_INFOS.pdf (short manual of JetsonSky functions)
JetsonSky_V30_03RC.py (old version using PyCuda; no ore support)
JetsonSky_V40_XXRC (supported version using Cupy)

Lib directory :
Libraries from ZWO SDK (Windows and Linux)

zwoasi directory :
Python binding to ZWO libraries (camera)

zwoefw directory :
Python binding to ZWO libraries (filter wheel)

Place all those files and directory in you work directory. You will have to also create 2 directories :
Videos
Images

Jetson SBC install :

You will have to know which version of CUDA you have.

You will have to install those Python libraries :
numpy
PILLOW
Cupy
Opencv (with or without Cuda extension)
Pytorch and TorchVision (optional)

To install Cupy, just visit this website :

You will probably have to upgrade scipy :

pip install -U scipy

To install Pytorch TorchVision, just go there :

In the Lib directory, you will find two files :
asi.rules
efw.rules

Just make this commands :
sudo install asi.rules /lib/udev/rules.d
or
sudo install asi.rules /etc/udev/rules.d

sudo install efw.rules /lib/udev/rules.d
or
sudo install efw.rules /etc/udev/rules.d

From what i can remember, everything is done. JetsonSky must work.

And now…

Windows system install :

You will have to install Python :

I use Python 3.11 and it works fine (do not use beta version or RC versions of Python)

Python will install PIP on you Windows system

You will have to install CUDA :

You will have to install those Python libraries :
numpy
PILLOW
Cupy
Opencv (with or without Cuda extension)
Pytorch and TorchVision (optional)

You will have to use Windows PowerShell to do this and type for example :

pip install numpy
or
pip install opencv

To install Cupy, just look here :

To install Pytorch TorchVision, just look here :

You can install GSTreamer if you need it :

https://gstreamer.freedesktop.org/download/

To be honest, i don’t know if we need to install Microsoft Visual Studio in order to get a C++ compiler. I should say no but not sure.

No need to install asi.rules and efw.rules for Windows system.

I think there is nothing more to do.

Good luck !
