This link will take you to the same marble shot with the Celestron InfiniView.

Nice concept.

I don't know about Earth, Brian, but my first thought was the moon with all those craters.

Everyone is free to agree with whoever. But i just spent the last few hours reworking the shot. What do you think of this version

It is just possible that a post apocalyptic Earth might look very similar to the Moon

The issue with this view is that the earth has an atmosphere, so even in a post-apocalyptic world, where would all the air and water go? The reason the moon view works is that the moon has no atmosphere to speak of, which is the reasons for all the lunar craters. Most of the things that make large craters burn up in the earth's atmosphere.

Hi Brian - Your second shot appeals to me much more than your first. I did not like the fuzzy outline of the first which reminded me of the view one would get from a cheap telescope. I will steer clear of the moon vs earth debate.
However, at the risk of re-igniting an old debate, I must ask you what you mean when you say that the shot was "exposure stacked in Fiji". The reason that I ask again is because the last time that I asked, you answered that you used the "Images to Stack" command in Fiji. That thread became, shall we say, toxic shortly after so I dropped out.
The "Images to Stack" command takes all the images that are opened in fiji and stacked them in the order that they were opened. So the top of the stack is the first image that was opened, the second one is next and so on until the last one which is at the bottom of the stack. The only processing that is done by the command is to optionally resize or align the pictures if they are not all the same size.
So my question is: What other fiji command do you use after the photos are stacked to create the "Exposure Stack"? I have searched the documentation and cannot find anything that would accomplish that. However, the program has so many plug-ins and options that it would be easy to miss it.

Andre, apologies but I have never figured out how to get an accentuated 'e' on my keyboard.

Okay after this answer I will not further comment on exposure stacking. If anyone takes a number of differently exposed shots and stacks them, just stacks them in Fiji the shots colors are changed. Both Stagecoach and Expat ran tests that proved me correct. That's all I do in Fiji, it works and that's all I will say on the subject.

One other statement on a different subject: Donald and Dave if this goes crazy once again please shut this thread down. And I will return to my new habit of not posting technical details with my shots.

WARNING SCIENCE CONTENT: THE FOLLOWING STATEMENT IS TRUMP SCIENCE

'The reason the moon view works is that the moon has no atmosphere to speak of, which is the reasons(sic) for all the lunar craters. Most of the things that make large craters burn up in the earth's atmosphere.'

The truth is that there is indeed limited atmosphere on the Moon and that there are many more visible craters on the Moon than on Earth. But the reason there are more craters visible on the Moon is that there is no atmospheric wearing away of the craters.

And, the Earth's atmosphere does not burn up the big stuff it burns up the small stuff. Ask the dinosaurs.

Bad camera science is not tolerated in this forum and it is my belief that just bad science shouldn't be tolerated either.

And that's all I have to say on this subject.

[shreds]

In a post apocalyptic world, do we know that an atmosphere would remain? Indeed what if anything would remain?

Keeping with the Photographic theme, I suppose the Hasselblad on the Moon would be there, but without a planet to orbit, the moon too may be fated?

Nevertheless I like your shot, we need things like this to keep us on the ball.

Brian - you are right. Weathering reduces the impact craters from the meteorites that have impacted the Earth, although in many cases the results are still visible even after tens if not hundreds of millions of years. With about 3/4 of the Earth being covered by water (primarily oceans), many of the ones that have hit have not left signs that are visible. The one that many scientists feel wiped out the dinosaurs, resulted in a meteorite impact in the Gulf of Mexico, just off the coast of the Yucatan Peninsula (Chicxulub crater). That one hit so close to land that it is relatively easy to identify.

Lac Manicouagan, in Quebec, Canada is an easily identifiable impact crater.

That being said, a mechanism that removes most of the air and water from Earth is one that is difficult to imagine. Gravity is our friend...

One of the joys of 'fantasy macro' is that one gets to suspend ones disbelief.

Hi Brian,
Sorry to take so long to answer your post but things turned unexpectedly hectic in the "Tuit" household. I just wanted to thank you for your unambiguous answer. It confirmed my suspicions and I guess that you and I will have to agree to disagree on this one since the results of Stagecoach and Xpat are also compatible with the process as outlined in my post.
If anybody else is interested in sorting this out for themselves, PM me and I will sent you a five minutes test that will shed light on the process involved.
André
P.S. I use a french canadian keyboard and don't know either how to make é on a standard keyboard.

André,

Are you on a Mac or Windows OS?

Holding down the 'e' for a couple of seconds on a Mac keyboard brings up a range of alternatives, which would be useful for you if your 'standard ' keyboard is an issue. It came in very handy for me when I was learning Mandarin! (which has four 'tones' for writing 'Pinyin' which is 'western' alphabet letters with different circumflexes depending on the meaning.

Obviously when using traditional Mandarin characters required a Mandarin dictionary/keyboard download and a keyboard overlay, things were very different.

Now there's a challenge……learning enough Mandarin to be able to write in that language…..very different to the Latin based languages common in Europe and your part of the world. Generally around 2000 'pictograms' to be able to read a newspaper as opposed to the 26 letters in English.

(Although I understand that English is very difficult for non native speakers too).

English is very difficult to learn in spite of a mere 26 letter alphabet. Comes from being a Heinz 57 language..

Reed, read, red, read, minute, minute and the list goes on.

Now this is what I call respectful. You have your understanding. I have mine. We allow the other to enjoy. Other members are free to make up their own mind. Thank-you.
