How long an exposure can you take of the night sky before you need a tracking mount?
You can leave an optional "tip" with Mahalo's virtual currency, Mahalo Dollars. If you are asking a difficult question that might require some research, or if you'd like a wide variety of feedback, a higher tip often leads to more answers to your question.

at 75 mm it can be seen at 6 sec
