Ive build a nightscape 8300 driver that's still pretty 'alpha' but perfroms fan/cooler and exposure control correctly. The image saving/downloading isn't completely stable because of some USB data transfer issues.
For stability, it needs the FTDI d2xx libraries but can run with libftdi1.
Is there any intereest in this? I know the camera is discontinued and support form Celestron limited now.
It was built based on reverse-engineering the messaging from the windows driver.
I have no idea how to run the non-KAF300 version of this.
