I forgot to mention before that when I adjust my gain/exposure for lunar shots I’m aiming for about 40% on the histogram

Yes, it was definitely a learning experience. The ISS vanished in the second frame as it crossed the over exposed, right hand edge of the moon, which is to be expected. Next time, I will keep the exposure lower and ditch the 0.5x reducer so that the focal length will be 2,032 mm.
The frame rate could to be USB limited. The computer is USB 3.0 and the camera USB 3.0/2.0. According to ZWO, I should be able to achieve 23 games per second (10 bits) and 15 frames per second (12 bit) with full resolution (16 MP). I am only getting 3 frames per second at the moment. The PC has an SSD drive. It could be a dodgy USB C to USB A adapter perhaps.
