The 'Destination Star Trek' event was held at the ExCel centre from October 19-21, and gave fans of the iconic sci-fi the chance to meet stars from the series.
William Shatner, Sir Patrick Stewart, Kate Mulgrew, Avery Brooks and Scott Bakula - all five captains from the TV show - were among those in attendance, while convention-goers took the opportunity to arrive in costume.
The event broke the Guinness World Record for the largest gathering of fans dressed as Star Trek characters, and hosted the UK's first Klingon wedding.
