Star Trail - test of longer exposures

27x4 min exposures on this one (first one using an external intervalometer) - with a 5 sec gap between each. f8, ISO 200. Not sure the pause is needed - and you can clearly see the gaps (have read that it allows the sensor to cool down - but those gaps in the trails are annoying).
