You need to create a dark frame (use the same exposure times as your actual images, but with the telescope covered up) - take ~100 frame (or longer) recording this way, and use Autostakkert to generate an averaged dark frame.
This works quite well at eliminating the hot pixels as long as they're not completely overexposed.
