I like the astrotrac a lot, even with a very very rough polar alignment using just a compass and declination I could expose for 1 minute instead of 20 seconds without it. With proper PA you can go for really long exposures. I tried 1 minute with a 200mm lens without visible trails too.
In this case I exposed for 1 minute because I was having a condensatin nightmare so I had to wipe the lens often.
