IC1396 The Elephants trunk dark nebula Taken while the weather was clearish. 9 x 10 min, 7 guided phd Atik16IS on the Celestron C9.29@f10 (2350mm) and 2 unguided - I stopped because of trailed stars caused by what I suspect is mirror movement. Strangely the unguided shots had the rounder stars ! Link-words: Nebula
