Gill Head: Kirkby Luneside's neighbour

As requested by a few people, another moon pic - this one was taken last Wednesday, May 11.

 

The original TIF file was over 20Mb, obtained from 4Gb of data taken over a 50 second period.

 

The large crater is Copernicus, one of the youngest on the moon (only 800 million years old) and about 100km across.

Incredible image Jeff.

100km crater takes a step to convert that to something

familiar in the uk.

About 62 miles in pounds shillings and pence.

I suspect that most of us don't really appreciate just how big the moon actually is, because we're just used to it hanging in the sky.

Rob, agreed, about 60ish miles.

 

So, Ade, the distance from left to right across the photo is about 600 miles, or the distance from Land's End to John O'Groats.

 

The moon is 2160 miles in diameter, a quarter as wide as the Earth.

 

I'll remember to put data in both metric and Imperial in future.

Glorious shot of Copernicus, Jeff.

Regarding it’s age -

Is the lack of impact sites within the main crater a clue?

Sorry but you piqued by inner geek.

No problem, David.

 

I'm away from the laptop at the moment, but if you look on here in an hour or two I'll post another mosaic from last Wednesday, from a totally different area of the moon with much older terrain.

Right, here are a couple of images from last week.

 

For those not interested, switch off now, as I want to explain something about these pics.

 

What you see is not a simple "fit the camera, press the shutter, take a pic" type of thing. You can do that, but the results wouldn't be anywhere near as good - for reasons that I'd have to ramble about, and you don't want to hear it on here!

 

The first pic is a composite image of 5 separate images, "mosaiced" together. EACH of these separate images is the result of 4000 images taken over a 45-50s interval, with 80-90% rejected (so keeping the best 10%, or 400 frames), and the best ones stacked by software to produce - effectively - 400 pics superimposed EXACTLY on top of each other to produce one, low noise image. Amazing that the pic you see is really the end result of about 30,000 images taken over 5 minutes and using 30Gb of hard drive space.

 

The final loss-free TIF file comes in at around 40Mb. I can't post that on here, so have to degrade it to a 2Mb Jpeg file.

 

Similar story with the second image.

 

 

 

The first pic shows the northern part of the moon, covering around 800 x 800 miles. 

 

The large "curved" feature at middle left is the Sinus Iridum. This is the north/western remnants of what would have been a 150 mile wide crater, whose southern/eastern flanks were flooded by lava fill when the large, plain area (Mare Imbrium) was created around 4bn years ago. The Mare is covered in smaller craters, but by the time this formed, most of the major bombardment of the moon (and Earth etc) had diminished as debris from the early solar system had already impacted other objects or had fallen into the sun.

 

The second pic shows the southern area of the moon. Very heavily cratered, with the newer (3.5bn years!!) superimposed on the older. The moon's crust was thicker here, and no major bombarding objects penetrated deep enough to cause large scale lava flows to "smother" the craters. The very large crater is Clavius, around 140 miles in diameter - it has several craters inside it. The smaller (55 miles) crater towards the top is Tycho, one of the youngest large craters on the moon (300 million years?)  Tycho was the site of the discovery of the black sentinel in Kubrick's 1968 classic film "2001, A Space Odyssey".

 

There you go, a potted summary in a few paragraphs!

 

Btw, these pics are very data rich - the original TIF files can be expanded to larger than laptop screen size with no pixellation. Don't think the jpegs will be so obliging!

[AdeMoore]

Those 2mb images on a browser and iPad look amazing, I imagine your Actual image on a big screen would be breath taking!

Superb stuff Jeff an enjoyable diversion to someone like me who has not a clue on the solar system!

 

Now about these overdue over bridge photos, last time I looked it was still Wednesday tomorrow, I must stay strong and not show weakness and hold out until Thursday! No pressure to post them earlier you understand 😅….

Bridge, Ade? What bridge was that?

 

I've actually just (in the last 2 hours) sprayed the track on the bridge with sleeper grime. Assuming I can breathe in there tomorrow I'll get more grass down and by Thursday it may be presentable enough to get the pics I promised.

 

I also, in the steps of Putin, have an on going "special operation", but that will be evident by the end of the coming weekend. I hope....

 

Glad you like the moon pics. More moon over the next few months and Jupiter later this year.

Hi Jeff,

 

Thanks very much for the great images and the background information regarding production. Perhaps I need to think along these lines to improve the amazingly poor quality of my layout/loco pictures...

 

2001, A Space Odysessy Was a great event back in 1968, you just had to see it. It was a true film classic. The more we learn about our Universe the less certain Physics becomes about explainations. It really is chaos out there......

 

Sorry to interupt the bridge discussion Ade!

 

Kind regards,

Absolutely fine, Richard. There'll be a flurry of layout stuff in a few days, so discussing Kubrick's film, space etc sounds good to me!

 

I went to see the film when it was released. I was in awe of the special effects, music score and enormity of the whole thing. Though as a ten year old, like many older people, I hadn't a clue what the ending meant. Worth reading Clarke's early 50s novella "The Sentinel" and the original 2001 book - set at Saturn, not Jupiter - for insights. First time I read the phrase "It's full of stars" I tingled all over, and it still has that effect.

 

As a Physicist I'm strongly in the camp that there are many, many discoveries yet to be made. Revising current theories based on evidence, throwing them out if necessary, is just part and parcel of the Scientific Method. Very exciting!

 

On the subject of the Moon, one of my April images has been published in the June 2022 issue of the national magazine "Astronomy Now", so chuffed about that.

By changing Physicist for Railway Modeller you get your approach to your layout, I think.

I'll second that but from the viewpoint of both an engineer and an artist. 😉

[Physicsman]

I'd better put a short update on here as I DID "promise" some pics on Thursday. And, of course, they didn't materialise.....

 

I'll post 3 pics below, but I have to admit that no work has been done on the underbridge area for a couple of days, so the rear embankments are still in need of tidying up and grassing etc.

 

I'm currently working on something that I think may take me 10 days to 2 weeks to complete. A really fun project, but I'm just going to get on with it and I'll post details once things are finished. And I'm not giving any teasers or hints!

 

 

 

[lambiedg]

Even relatively humble railway bridges have a fair degree of heft to them.

Captured wonderfully here.

I fully support that view Mr Wolf, I too am an Engineer (retd) and enjoy fine art. Even us engineers dabble(d) in Physics and the scientific method. The way that maths and physics are converging around cosmology is fascinating. The huge gulf between us clever apes and the universe that we contemplate and try to explain is simply amazing. As a rather famous scientist once said, the human imagination is our greatest attribute and tool, or words to that effect.

 

Back to building a N15 4-6-0......

Well I booked a day off work stayed in all day yesterday and nothing not a glimmer of any pics turning up! 🙄😉

promised delivery and everything! I feel a bad review coming on 😂

Joking aside Jeff looking the business.

Now on the other piece of news no hints or teasers! You rascal! Reel em in reel em in I know that’s what you’re thinking. We’re not rising to it are we lads?

Cheers

Isn't the mere mention of a "fun project" teasing in and of itself?

I was fooled into decorating our new flat with that one.

Still, that has opened the door for railway projects.

Railway modelling is really great fun all the time, isn't it? Don't think I was being serious there.

 

Watching glue dry isn't exciting, but productive.

 

No clues or hints, except to say don't expect anything spectacular!

I'm simply modelling a prototype situation on the S&C and it's going to take quite a while to build all the components of the scene.

 

No further comments from me until I post something modelling related, whenever that might be.....  😀😊

Layout's coming along well Jeff, I always look forward to checking out your thread. You do seem to have the knack of capturing the essence of the Settle & Carlisle.

Away I'm glad I still seem to be able to put a smile on someone's face!

 

Hope that you are well

Hi Shaun.

 

Good to hear from you, and the humour is much appreciated. Very much in keeping with the input from the rest of the gang on here.

 

The elements of the layout - viaduct, bridges, shed, walking etc. - take a lot of time, as you well know from your own experience. For some things it'd be easy to go for the quick fix, but then it wouldn't be my own work.

 

The current construction might be at a presentable stage in a week's time, we shall see!

Edited May 22, 2022 by Physicsman

[Sasquatch]

Looking forward to it. 

It does take time, I spent the winter building a warehouse and this month putting right a wiring job that I did in a rush and totally hashed up. In my defense, it was a bit complicated but I did have to dismantle most of the layout. However I'm glad to report that it now works and that I can get back to the more creative side to the hobby. Grass etc. 

There's just not enough time. What's needed is a couple of clones but if I actually think about it, things would take much longer if there were three idiots procrastinating, arguing and getting in each others way all the time.
