These cosmic clouds can be found 1,300 light-years away in the constellation of Cepheus and is called the Iris Nebula (NGC 7023). This deep telescopic image shows off the Iris Nebula's range of colors and symmetries embedded in surrounding fields of interstellar dust. Within the Iris itself, dusty nebular material surrounds a hot, young star. The dominant color of the reflection nebula is blue, which is because of dust grains reflecting starlight. Central filaments of the reflection nebula glow with a faint reddish photoluminescence as some dust grains convert the star's invisible ultraviolet radiation to visible red light. Infrared observations indicate that this nebula contains complex carbon molecules known as PAHs. People tend to say that this nebula reminds them of a flower, so it’s dusty blue ‘petals’ span about six light-years.

Photo of the Iris nebula / Caldwell 4 / NGC 7023, I'm very pleased with this one since I finally managed to capture the surrounding dust (barely visible in the 2 previous attempts). This is a reflection nebula, this means that it's a dust cloud reflecting the light from a nearby star. Being one of the brightest reflection nebula visible in the northern hemisphere it's visible in relatively small telescopes (4-6 inch / 100-150mm diameter), unfortunately the outer dust clouds can only be seen on photos. Reflection nebula generally tend to be blue due to a more efficient scattering of blue light compared to red by the dust particles (M45 in my previous post is another good example).

Chapter 21! So this is a shorter chapter because it is setting up for three longer chapters and im pretty sure this chapter is marking our arrival to the end of this fic

I hope you guys enjoy

———————————

The wound still hurt but Gauche decided to power through because now Yami called Vanessa, Henry, And him, alongside Nero, Gordon, Magna, Luck, Finral, Charmy, hell even Nacht showed up, and he never showed up for anything before. They were all worried sick about Grey and they all wanted to save her as much as he did. And this was their chance, thirteen hours that’s how long it’s been since they lost her, but no longer they were planning on attacking the Zogratis head on and save their beloved. But it will be hard, they knew that. Yet they didn’t care.

“Alright listen up, I know how everyone feels right now.” Yami sighed. “But that doesn’t mean we’ll just roll over” he told them as he started raising his voice. “Will we just let them have Grey?”

No

“Are we just going to stay put?”

No

“Are we just going to leave her behind?”

“No!” Gauche yelled out.

“Exactly, We are a family and if one of us is in trouble we help them.” Yami told them all. “God knows if we’ll actually succeed, but I know we are all willing to die trying then just walking away.”

The room got tense.

“So, if you decide not to go we’ll understand, I don’t want to force any of you to risk your life.” Yami reassured them, wanting to give them a choice. “So if you don’t want to go just say, but if you’re with us please stand.”

Gauche was the first to stand.

Quickly followed by Vanessa.

Then Gordon.

Then Nero.

Then Finral.

Luck.

Magna.

Henry.

Charmy.

Even Nacht.

Yami Smiled, he knew they had made up their minds once they heard the news.

“Good, now listen up.” He took a drag of his cigarette. “Here’s the plan.”

They listened as Yami explained the plan to them. It was simple: Yami, the Black bulls, and the other Bosses would be the diversion stealing the Zogratis’ attention that way Gauche could sneak in and rescue Grey. Again Simple on paper but they all knew it would be no cake walk, The Zogratis had the fire power, the men, and the resources. So Gauche had to be quick and get to her before they crumbled, but they also had to be careful due to Vanica being the main commander of the Zogratis army, and they knew what a wild card she was. So for that they decided to assign different people to each Zogratis sibling. Vanessa volunteered Finral, and herself to fight Vanica (much to Finral’s dismay) And Iris barged in saying she volunteered too, Yami said that he and the other bosses will handle Zenon. And as for Dante, Gauche said he would handle him.

“Gauche, you know if you face him he won’t let you live this time around.?” Yami asked Gauche.

“I know, but I also don’t plan on letting him live.”

Yami looked Gauche in the eyes, and he saw a man, a man in love, wanting, yearning to save his beloved. Yami gave Gauche a nod knowing he was determined, and they need that determination.

“Okay, then operation: Save the cinderella, is a go.”

Everyone was ready.

Everyone wanted to save her.

They wanted to save Grey.

StARS Presentation

On Wednesday, April 24th, I presented at the Student Arts and Research Symphosium, or StARS for short, alongside my classmate, Cameron Williams. At the event, we presented our pictures of the Crab Nebula, comparing our edits against one another's. Alongside our Crab Nebula, we had pictures of the Flame Nebula, and Saturn, which I had edited, as well as Cameron's image of the Iris Nebula. Throughout our time presenting, we had multiple people approach our poster, asking questions about how we edited our images, as well as why we chose to colorize the images that we did. We received numerous questions regarding our class, as well as how long we worked on each image. We explained to people how long the images took to create and dove into the details of the steps we took, highlighting our use of the curves tool, and the levels tool. Cameron and I also explained how we aligned the several layers of each image, as well as explained the difference between each layer to the people who approached our poster. We touched on the three screen layers, and how each were either green, red, or blue, as well as the top layer, or the luminance layer. Presenting at StARS was a fun experience, allowing us to showcase our newly learned knowledge in image editing. It also allowed for us to see the differences in each other's posters, as well as other posters from presenters outside of our class. The presentation was a good and fun experience and allowed me to really discover how much I learned over the course of the semester.

Iris Nebula

This was a very quick assignment due to the time crunch but the Iris Nebula was the second set of images that I had edited. Unfortunately, I cannot attach the photo due to having a Chromebook and the GIMP software does not allow that. For this assignment I simply did what I did to the Crab Nebula. To begin, I exported the images into GIMP. Then I would go onto the "colors" tab and hit the "curves" tool. It was pretty simple, I just moved the bar from the graph up a bit and it began to lighten my image. I then did that step a few more times until I felt like the image looked brighter but not too much brighter. I also went on the "colors" tab and clicked on "levels." I then moved the histogram up a bit to help with the pixelation. I felt like my picture was not changing too much but it still turned out much better than what I had started with. I was not too happy with my image (just like my Crab Nebula image) just because I truly did not see a dramatic change. But it definitely did still turn out well.

SPACEMAS DAY 5 ✨🪐🌎☄️☀️🌕

Time to pull out one of my favourites! These stunning cosmic clouds have blossomed 1,300 light-years away in the fertile starfields of the constellation Cepheus. Known as the Iris Nebula, NGC 7023 is not the only nebula to evoke the imagery of flowers. Still, this deep telescopic image shows off the nebula’s range of colors and symmetries embedded in surrounding fields of interstellar dust. Within the Iris itself, dusty nebular material surrounds a hot, young star. The dominant color of the brighter reflection nebula is blue, characteristic of dust grains reflecting starlight. The central filaments of the reflection nebula glow with a faint reddish photoluminescence as some dust grains effectively convert the star's invisible ultraviolet radiation to visible red light.
