[QUOTE="WayneF, post: 214125, member: 12496"] No gaps. You don't see the stars move in 3 seconds. Stars roughly move (360/24) /60/60 = 0.004 degrees per second. That's a lot at 200 power in a telescope covering 0.05 degrees, but your star trails use a wide angle lens (creating pretty small image objects). 18mm FX for example would cover a 90 degree field.
