The Official Star Trek Convention | Photo gallery

Trekkies were out in force at this weekend's Official Star Trek Convention at the Westin O'Hare Hotel, celebrating the 45th anniversary of the seminal sci-fi franchise's inception. Actors from every iteration of the series were on hand and merchandise booths were overflowing with all manner of phasers, autographed memorabilia and stuffed Tribbles. All of this is leading up to Sunday's appearance by everyone's favorite Vulcan, Leonard Nimoy, who will be making the final convention appearance of his career. We boldly ventured to the event and brought back these photographs.
