Charlie Sheen, Patricia Heaton, Camryn Manheim, and more descended upon the illuminated ET stage Thursday to support our own Mark Steines. Our host took time off from his on-camera duties and stepped behind the lens as he traveled through Africa, chronicling his trip with photographs in the book "See the Light -- A Passage to Sierra Leone."

Steines said, "This is just my way of bringing about a little change in the world. I'm making a difference and doing it with something that I absolutely love doing, and that is taking pictures."

The stars gave Steines' photography rave reviews with Heaton and Manheim both calling him a "spectacular photographer." Heaton, who accompanied Steines on his trip, added that "the images he brought back were stunning."

Steines, an Emmy-winner, was blown away by the friends and family he attracted to the event, saying, "Everybody is standing right smack dab in the middle of my dream."

Sheen thanked Steines for taking him on "an amazing journey" through the images he presented Thursday night.

Steines said the trip "really changed my life to see what they have to cope with and how they have to live. It is a nation of children raising children. They have the highest infant mortality rate in the world and yet I've never seen highs so high in my entire life and it's because their lows are so low..."

He proudly announced to attendees, including ET's Mary Hart and Kevin Frazier and "The Insider"'s Lara Spencer and Chris Jacobs, that his efforts through the book have already raised over $50,000 for Lighthouse Medical Missions. Click here to purchase "See the Light -- A Passage to Sierra Leone."
