IC410 - The Tadpoles in Ha

18:10 17/3/2010 UTC

Spring sky is pretty much void in emission nebulae, but this nice complex in Auriga is still well visible. I started shooting a tricolor narrowband project, beginning with H-alfa. Temperature was dropping quite fast and eventually my tracking went bad due to stiffness of the cables in cold. I managed to get 3h worth of 15min subs which is quite a satisfying result given the conditions. So here is part 1/3 of this project. Hope I can get a one good moonless night for OIII before summer nights.
