It really depends on the situation but as a rule of thumb its best not to go over 30 seconds to avoid star trails. I average between 15 and 25 seconds depending on the lens, camera and phase of the moon. Here is a good explanation of the 500 rule https://petapixel.com/2015/01/06/avoid-star-trails-following-500-rule/
