A lightsaber wielded by Darth Vader during one of the most iconic scenes in "Star Wars" history is heading to auction, with an expected price of at least $1 million.

Big picture view: The prop, used in the climactic duel between Vader and Luke Skywalker in "The Empire Strikes Back" where he tells Skywalker "I am your father," is among the highlights of Heritage Auctions' Ultimate Star Wars Auction on Nov. 12.

The weapon also appeared in "Return of the Jedi." More than two dozen lightsaber props spanning "Star Wars" Episodes I through IX will also be available at the November auction, along with memorabilia from other films and television shows set in the galaxy created by George Lucas.
