For normal Milkway shots with a wide angle lens on a tracker, it shouldn't be necessary to push the Star Adventurer beyond the 45sec or 60sec for trailless shots. I thought since I now know with accurate Polar alignment the Adventurer was able to achieve 45secs exposure without any trails, I ventured to test exposures beyond 45sec on the EF400mm. This might be useful for capturing images of Andromeda, Pleiades or Orion Nebula come next fall.
For this session I targetted Capellawithin the constellation Auriga. It was another clear sky night in Spring, though a tad foggy at lower elevations conditions around Auriga was clear.

Stack of 36 shots, each was exposed at 45secs, ISO 1600, pp in Gimp.
Stack of 5 shots, each exposed at 122secs, ISO 800, pp in Gimp.
After almost a week of cloudy and/or foggy sky the stars revealed themselves when both elements took flight finally. Though they are not completely gone it was clear enough for some night time imaging.

While some friends were chasing KP3-4 aurora in the moisture laden lower elevation sky, I decided to give the stars a shot or two. The temperatures wasn't extreme but the grip of winter has completely been let go so it was cold around midnight, colder still when wind blew.
I attempted another session at Vaulen with the intention of getting away from light pollution, however being located right smack in the city this proved rather futile. Light pollution is everywhere and it seems you can't escape it no matter where you are in the city.
