Hello all,
you surely know about StarNet and its PixInsight module and we all know it can be very useful for generating Star Masks. However we also all know that is very slow.
We (well technically, @patdufour) have found and documented a way how to run StarNet on the GPU. At least for Windows and nVidia GPUs. It might be very specific but maybe this will help someone out running StarNet faster.
In terms of speed; I did test runs on my example images (8.3MP, drizzled 2x, 6708×5058)
CPU (Ryzen 7 2700X): 03:45.94 (that's 3 minutes, 45 seconds)
GPU (2080Ti): 25.804 seconds
For me this gives a 9 times speed increase. Results may vary but the GPU will pretty much always outperform the CPU.
Edit: The Guide has been udpated for PixInsight 1.8.8-6
Long story short, you can find the tutorial how to set it up here: https://darkskies.space/pixinsight-starnet-cuda/
Thanks for reading and have clear skies,
Stanley
