  • Now we're going towards the Clayton Observatory.

  • Well, it's the only observatory at Clayton, So this is my little observatory, and I'm known as the mad astronomer here.

  • This is a small observatory's bet.

  • 10 square meters.

  • Um, built this three years ago.

  • This photograph is off satin taken at three different periods during the course of the night.

  • It actually shows a photograph off what's called the Dragon Storm.

  • It's a big storm that became evident after the ring crossing for long periods of time in sentence orbit.

  • The rings cover one hemisphere the planet with the Northern Hemisphere.

  • It's just come out of, Ah, long period time.

  • About 13 years.

  • All of a sudden we started getting this storm activity.

  • The reason why this is fairly important because I came second.

  • Thio Damian Peach of the UK in the Solace is system section for the astronomy photographer of the Year award.

  • Absolutely state totally did not expect any of this at all.

  • I honestly thought that your door okay, but that was that was a bit of a surprise.

  • I knew on the night that the equality was very still.

  • I could see Cassini's division through the eyepiece and I could see hints of the Ikea division, which is very, very small.

  • It's technically not, you know, I will see it, but I could see it.

  • So I thought, This is fantastic, not think a division rise.

  • This is a consumer division that's the black, the black one.

  • And on these little pieces here you can just on the edge.

  • You can just see a little thin line here.

  • Very tiny thin line.

  • That's the division.

  • It's about 300 kilometers in which so it's very, very special to be out to get that when I processed it.

  • It's the sharpest image I've ever produced off that particular object really enjoy taking planetary work and when the the equality is very, very good, very still very transparent.

  • You get great images like this, and they have very rare and few and far between here and set Australia.

  • Actually, this image wasn't taken here.

  • This was taken in at a light.

  • I have a similar amount in that light, much bigger telescope, a 14 inch telescope made by Celestron a little bit bigger than that particular tell escape there.

  • That telescope is designed purely for taking planetary work, so the conditions were very, very still.

  • It's very stone.

  • I walked outside, I looked up and the stars weren't twinkling.

  • But all that was no simulation.

  • There was nothing.

  • It was just still when I looked in the our pace that I knew what was going on.

  • This this sort of imaging is is done with tri color imaging, red grain and blaze filters.

  • I take a video in rid.

  • So for this one, for instance, about two minutes in red two minutes and green two minutes and blue in that period of time, the camera takes lots of lots of friends, like a video at about 30 30 to 40 frames per second.

  • At the end of that, when I go to go inside the processing starts, that's where the real work starts.

  • The capturing sort of is be automated works.

  • I have some software tens of filter will takes turns the camera on off that sort of thing.

  • Damn lights.

  • That sort of stuff processing side of it is a little bit complicated, but the short of it is, it stacks all the good frames, so there's a selection prices of the good frames, and then you combine all those good friends together and then shopping a little bit, taken into another piece of software, shopping a bit more, and then finally into fighter shop tow.

  • Get the color rendering rock.

  • So when you look through your telescope with your naked eye, can you even do that?

  • Is there an eyepiece on your telescope?

  • See that?

  • Did you see satin with your naked?

  • Absolutely, Absolutely, Yes.

  • You can see in any telescope setting looking like this on a really good night.

  • Most people see it much smaller, much smaller 20.

  • It'll be a P attorney, but you could see Daito at higher magnification.

  • The air moves in a bit, but if the on that particular night it looked like this, you could see that storm.

  • And yes, you can see the storm.

  • That's because that storm has what's called a quite high albedo feature.

  • It's actually contrast.

  • Did quite well against the planet.

  • Doesn't look that colorful.

  • Will you cut it with your eyes on?

  • That is interesting most the time it looks like a yellowy orangey color.

  • Um, on some nights, particularly around the time of opposition, that's when it's opposite the sun and to us and we're in the middle, you'll get the rings being really, really brought on by all sort of.

  • That's called the ceiling graphic.

  • Jupiter, on the other hand, produces color.

  • You can see red, and you can see festoons of blue and all that sort of thing.

  • You got a picture?

  • Yes.

  • So you can see here There's some color here and that the festoons in the in the central area, which is called the the Equatorial Belt.

  • You can see the moon here that has some detail on it and, of course, the great red spot, which has been around for 300 years.

  • Most people would know about that.

  • Jupiter is more colorful.

  • Visually, it is.

  • Yeah, you need a good night to get good detail, but you can see more color in it, the blue festoons in particular, off obvious to the R.

  • In this day and age, there are some amazing pictures of satin going around.

  • There's a space probe currently at seven.

  • What's the role for someone like you?

  • What's the point of taking pictures of setting on earth when we can just go into the NASA website and look amazing pictures setting what?

  • Why do you do it well.

  • Interestingly, amateurs can contribute quite a lot.

  • We have the capacity to take a lot of lots of images because there's thousands of us during this now.

  • Admittedly, when, in 2004 when I first started doing planetary imaging, there weren't many people around.

  • There were probably 100 or so, um, contributing.

  • Now there's thousands and thousands of people, which is great because any one point in time someone is taking an image off one of these great planets.

  • And the beauty of it is that we can contribute to science programs.

  • Scientists need to have photographs to compare, and Hubble's not always available.

  • Cassini is not always taking images at the same time, so we can actually contribute as emitters to actual science programs.

  • The Jupiter images, for instance, I contribute Thio GPA switches through the British Astronomical Association.

  • Scientists use these images just specifically firm confirmation of their theories and their ideas so we can contribute.

  • Is that why you do it?

  • Yeah, absolutely.

  • That I like to make pretty pictures.

Now we're going towards the Clayton Observatory.
