Update; Euan's not so Grand.
The Glenrothes pro, world No.62, went down 9-5 to Welshman Mark Williams who was rated No.16 but is now provisional No.4.
Henderson was compensated with a pounds 32,000 cheque, while Williams pocketed pounds 60,000.
Euan said: "I now realise these top players are under pressure every time they play.
"It's serious business out there and while I enjoyed it, it's been a long week and a half."
Henderson handed Williams a five frames burst during the opening session.
He said: "I was really subdued and it didn't help me to settle down knowing that it was going out live across the nation."
Williams dashed off the last two frames in 22 minutes - including a 138 clearance which gave him an extra pounds 5,000 for the televised high break, beating Euan's 133.
