Another thing to watch out for other than regions of non-scoopable stars is close binaries. If you apprach a binary pair of stars that are really close, you can pop out of hyperspace between them and nicely cook your ship. I took my cobra down to 77% hull doing just that and I was very quick to react to the situation after it happens. Nutter has a fantastic thread with a guide on how to avoid this exact problem. Worth a read BEFORE you do what I did and knoack around 30% of your hull off lol, especially if you are in an Asp.
