Standardising Jupiter images for posting. Do you have a preference

[[1ponders]]

This has sorta been bugging me for a while now (see thread "Which way up for Jupiter (http://www.iceinspace.com.au/forum/showthread.php?t=10290)") and I'd be interested to see if we can reach some sort of concensus on this issue.

The poll is: Is it important to have a standardized orientation for posting images of Jupiter.

The standard I am thinking of is the one used by ALPO (http://www.lpl.arizona.edu/~rhill/alpo/jupstuff/recobs.html) GRS at the top (south at top) with festoons sweeping west (left) and pointing east (right)

What are your thoughts?

[matt]

Don't know how important it is to have a "standardised orientation" but from an aesthetic standpoint that's how I like it: south up, and festoons sweeping left to right.

But for the sake of voting and not taking a negative option I'll go option 1.

Each to their own though:)

[asimov]

I voted 'it doesn't really bother me'

But I prefer to see the GRS at the bottom really. No preference as to sweeping/pointing of festoons etc.

[Chrissyo]

I think it depends on what kinda image you're getting. If its just a simple pic of the planet, then it doesnt really matter. But if you're trying to do something scientific with it, like tracking ovals/storms etc, then it would be best to have a standardized system for displaying them.

I'm certainly of the belief that a standard will help in simplifying the identification of features and comparison of images. I don't think it should be compulsory, but rather an (to use the politically correct terminology :P ) advisory standard. :lol: Man I sound just like a bureaucrat.

I also think each image would benefit from a UT timestamp. This is already done by some posters, but it may not have occured to those new to the imaging game how useful timestamps can be.

[jjjnettie]

It doesn't really bother me what orientation is used when posting a pic of Jup. I agree with Chrissyos reasoning.

[Astroman]

Doesnt bother me either, what happens if you cant see the GRS :P

[Wombat_In_Space]

I don't mind which way the image is when it is posted, who has the right to say which is the right way up. :P

[ballaratdragons]

Are you guys for real????

Does it really matter which way up, or which way the festoons are going!

If I was going to use a 'Stanard' as you call it, I would have to suggest GRS at the bottom coz EVERY astronomy book I look at, the GRS is at the bottom! Images from Earth, from Pioneer spacecraft, Voyager spacecraft, Aust Sky & Tel mag, S&S mag, etc. etc. have GRS at the bottom.

And if you have a Standard on Joop, how about Saturn! Rings up or rings down?!!! All the publications I just checked show Saturn in both aspects.

Does it really matter. Can't we just enjoy looking at the pics instead of trying to Standardise evrything.

:screwy:

OKay I will add to this now. This forum is not a scientificaly driven forum, meaning that it's sole purpose is not the study of Jupiter or its dynamic system. There is no specific research going on to have the images made to be one way or the other. Having everyone turn their images inside out back to front is not what this forum is trying to do. If there was actual research done on the side of the forum like in a "scientific study of Jupiters dynamic atmosphere" thread, then the image posters would have to conform to the rules or guidelinesset out by the research group.

As for this forum,hope I am not speaking out here, Post whichever way you want, its about bettering yourself if your into imaging, and showing or entertaining people with the images you are producing .Lets not get carried away with things like this, next it will be which way should the moon be imaged.

[ballaratdragons]

Just to throw a spanner in the works :D

[leon]

Making rules and regulations of how an image is posted takes away the enjoyment of those of us less experienced to enjoy just imaging, and posting for the pleasure of being involved with a group of people who enjoy the night sky.
to us an image others might find "crap" we see as our best at that point of our experience.

[[1ponders]]

Wow! I wasn't quite expecting such strong responses from this.

I agree Andrew, but it doesn't mean that what we are doing is not science, or that valid scientific data can't be achieved from it. I am an amateur astronomer, that makes me by definition an amateur scientist.



Once images are posted here we have no idea how those images might be viewed or used. I have used information gained from images from this site and elsewhere in my current Uni project. With permission and appropriate acknowledgements in the report.

There are many beautiful images posted on this site, there are also many images posted that would be of real scientific value, not just Jupiter images. If someone wanted to post an image that they felt could add to a scientific investigation at some time I believe it would be useful to them to know how to post their image in a way to be of the greatest benefit to others. This will not automatically take anything away from the beauty of the image, but it may add another dimension to the value of it.



It was never my intention to try to standardise anything Ken. I was simply asking the question what people thought of the idea and if it would be benificial to have some form of voluntary guidelines for posting if a person was interested.



No mention or rules or regulations was made Leon. To me part of the enjoyment of learning the art of imaging is learning how to best present the image. Not everyone will be interested in this aspect of imaging, and I have no arguement with that, but it doesn't mean if someone is interested they shouldn't be able to find out about it. And isn't this part of what the site is all about? Spreading information to those who are seeking it?

I voted 'Doesn't matter', simply because it doesn't.
For those that it does matter to, may I suggest that when you post your images, you stick to the standard.. To each his own..
Hope I haven't offended anyone, but you did ask... :shrug: :D L.

[ballaratdragons]

It's OK Paul.

Everyone will have a different view on the subject. (same as most subjects :lol: )

I'll trust NASA's aspect: http://www.nasa.gov/multimedia/imagegallery/image_feature_97.html

But then again my spacecraft might be upside down!

Now which way is upside down :lol:

[matt]

I too couldn't give the rat's proverbial which way people post their jupiter images, but I appreciate being asked what my personal preference is.

I think a few people have over-reacted to an honest attempt to simply establish or discover what the norm is for the "correct" orientation of a jupiter image,

I never saw the question as a prelude to a new bunch of rules and regulations.

Talk about authority paranoia:screwy:

[iceman]

I agree with Matt..

As to the subject, I voted ALPO standard and I'll continue to post mine using the ALPO standard, because my images are to be used for scientific analysis.

[ving]

I think the grs should be on the right... :rolleyes:

it doesnt really matter...

[Robert_T]

doesn't really bother me, so long as everyone does it the same as me ok:P

seriously though, I like the more casual approach - I found the more stringent and demanding criteria for presentation on Mars Observers, for example, a bit intimidating, though as a science site I understand why it's required there.

cheers,

[h0ughy]

Time to leave the padded room Paul, your thinking too hard:D Just take them as they come, let your mind work it out what orientation you like. :P

[sheeny]

I voted for "it doesn't matter to me".:) Cause it doesn't, but I can see value in it! As a novice imager, though, I like the freedom of being able to take the image and post it in whatever orientation it ends up, without feeling like a dill for doing it wrong! I think that is important for novices.

I'm quite happy just rotating the image so the bands are horizontal:P . I have to admit that at the moment, if I had to rotate a Jupiter image to the correct orientation without the GRS in view, I reckon I'd have a 1 in 8 chance of getting it right.

However, after having read this thread, I think I'll take a bit of time to try to learn how to do that.

A date/time stamp on an image I think is a good idea. I haven't done it on my images, I tend to rely on the K3CCD time stamp in the filename. If the file gets renamed though, that is quickly lost, and so is a lot of the image's scientific value I suggest.

Well, Jupiters location means that more and more southern hemisphere imagers will be getting good images over the next few years, and so the number of us contributing to online databases like ALPO is increasing - there are people in europe and the US who measure cloud movement in those images to help understand the dynamics of Jupiters atmosphere.

The orientation issue only matters for people who are considering contributing to ALPO, but the effort required to get Jupiter roughly horizontal during capture is so small that I don't understand why it's an issue? It takes about 10 seconds to rotate the camera to fix it, it's something I routinely do now, like polar alignment and aligning the finderscope etc it's just part of the normal routine.

As long as jupiter is horizontal when you capture then x/y flips can be used to get whatever orientation you like (south at top or bottom, preceding limb left or right) without damaging the image.
