The main parts of a microscope include the eyepiece, objective lenses, stage, diaphragm, light source, and focusing knobs. The eyepiece is where you look through to observe the specimen, while the objective lenses magnify the specimen. The stage holds the slide with the specimen, and the diaphragm controls the amount of light passing through. The focusing knobs are used to adjust the focus of the image.

The diaphragm in a microscope controls the amount of light that passes through the specimen. By adjusting the diaphragm, you can optimize the contrast and brightness of the image being viewed.

November of next year is 50 years since the wreck; a big one. While Mixter acknowledges there will be a remembrance for the 29 guys who lost their lives, he says there's so many other chapters beyond this just being a grave site.

"It was just overwhelming what water could do and how this could have broken up on these big waves that we think were three stories tall. It snapped it, and the entire cargo area was like a massive cavern right in front of me."

"Sure enough, here's a guy on the bottom wearing what appears to be some kind of a jumpsuit. Clearly this guy had his life jacket on. So that brings in just a lot more clarity to what those final moments might have been."

GRAND RAPIDS, Mich. — It's part of Michigan and midwest lore. Lost to the depths of the Great Lakes, the SS Edmund Fitzgerald sank on November 10, 49 years ago.

A specimen is in focus when you can clearly see and distinguish its details when looking through a microscope. Adjusting the focus of the microscope allows you to bring the specimen into clearer view.

The substage in a microscope holds the condenser, which focuses and directs light onto the specimen. It also contains the diaphragm, which controls the amount of light passing through the specimen. The substage plays a crucial role in controlling the illumination and contrast of the specimen being viewed.

He said, "There's still that ethical question with so many people who lost loved ones who are still alive, is it fair to them that we go back and do that, and that's weighed upon my heart for sure.

The diaphragm or iris diaphragm controls the amount of light that passes through the specimen on a microscope. By adjusting the diaphragm, you can regulate the brightness and contrast of the image.

He said, "[it was] crystal clear water as we went down 200 feet, and then soon the light started to go away, where the sunlight cannot get down that deep,"

Mixter added, "Our submarine turned around, and on the port side was these massive letters that said Edmund Fitzgerald, but the plates were all crumpled from the impact of the bottom, and it was devastatingly destroyed, but I could still read through the little port holes Edmund Fitzgerald. And I couldn't believe it."

The Diaphragm or diaphragm control lever regulates the amount of light passing through the slide specimen on the microscope stage.

It's the largest ship sitting at the bottom of any of the Great Lakes. However, it's largely a mystery shrouded in darkness.

"Because of the notoriety, because of the song from Gordon Lightfoot, everybody wants to know about the Edmund Fitzgerald," said Ric Mixter.

"We set sail that night, and it was a late July day," Mixter shared. "I remember going through the Soo Locks, just not believing that we were going to actually go down 500 feet into Lake Superior."

"It's pointing now that this ship did not go down in one piece. It crunched on the surface and broke into pieces there."
