I have an old Canon PowerShot A630...not a great camera, I know, but I wanted to give it a try!
I have flashed the firmware of the camera with "Canon Hack Development Kit" in order to have custom exposure time (factory limit is 15s) and RAW output images.
The camera was on piggyback to a Celestron CPC800. I've taken 14 frames of 30s each, with darks subtracted by the camera (each shot is actually 60s: 30s dark + 30s collection). The settings were: 800 ISO f/4.1 140mm effective focal length and 30s exposure. I've stacked the 14 frames with Sequator and played a bit with PS mobile...again..it's nothing compared to pictures of Pleiades taken with DSLR cameras but considering the gear I've used I'm really happy with the result...You can even see some of the bluish gas halo around the brightest stars!
