Hi,  Thought I'd share a star trail and ML & photoshop settings.

ML settings

Exposure 20 seconds (ISO 800 f4)
Intervalometer photo ever 30 seconds


Import each frame into photoshop stack (File, Scripts, Load Files into Stack)
Select all layers
Select blending mode to Lighten
Add a threshold adjustment layer and adjust as desired
Add a curves adjustment layer and adjust as desired ( I used the double arrowed icon on lhs and dragged down on a dark area)


There's quite a lot of light pollution where the shots were taken.  the bright trails show the stars of Ursa Major  (big dipper)

Hope you like oh and btw I'm using the beta of Canon 100d
