If you made a link to your own image hosting would that be okay because it would mean you could change your image as much as you want without pestering anyone

The way I interpret the rule is practical. We allow a link to an image stored elsewhere, as long as it's the same image. It can be a higher resolution version. But, it must be the same image. When I make up the poll I capture the image posted in the submission thread for the poll. I will include the link to the higher resolution image. But, for the purposes of the poll, the image posted in your submission is the image entered in the contest.

For example, I don't think the poll would work if, instead of a posted photo, there was just a link. Also, if there were only a link there would be no control on changing the image even after voting in the poll had begun. There is also the risk that the link may break or your other site could go down.

If I'm understanding the poster correctly then what he's saying is that the image on the remote site is displayed *as* the entry on CN. In this case the poster could conceivably edit the remote copy to their heart's content as long as:

  • the URL back to the image doesn't break (i.e. the file name remains the same)
  • the image meets the criteria specified in the rules in every respect


If either of these conditions weren't true then the image would be disqualified.

That's a very interesting idea- I'm going to try that. Now I just have to get out and image if I can get a clear night up here!

We'd have to use the UBB Image tag I assume.

Hiyas

IMHO, rules are there for a couple of reasons, one of which is the help even the playfield somewhat. As i see it, having a 2 MB pic that's 800x600 is going to look undiscernable to most as compared with keeping under the 100k limit...however, not everyone has access to storage of large files so I think if someone posts a super widefield at 12 MB and is able to enter it as valid, then there may be an unfair advantage here. Lets be serious, no one's going to win a Pulitzer Prize here...its a fun contest for amateurs such as myself and limiting an image to 800x at 100kb is a simple rule, easy to follow and allows the submitter to have everyone see what the entry has to offer. Let the images stand on their own merits, and everyone upload them here. If there's a concern regarding frequent changes to a pic, then I see no problem limiting 1 change per contest and that way, we may be a bit more careful about our submissions.

I think that's what Charlie was saying- only 100k, 800x600 max images are allowed whether they are stored offsite or on.

Many websites offer free storage of fairly large images- Google offers a gig of free storage for example- that's almost 10,000 images at 100k each!

That might be ok, but it's not currently possible to limit it to one change. It's currently limited to x number of days- I suspect it's around a week or less.

IMO, I think we should encourage early entries to get more images uploaded. If someone shoots something and it's a little off focus or there was a full moon, then is able to get out again and get a better shot I think that should be encouraged rather than discouraged. I like to think one point of these contests is to challenge us to improve our imaging ability. By saying you've got one and only one shot at imaging I think that discourages this aspect of the contest. As you say the main rule is to have fun! I just want things to go smoothly between the entrants and the moderators. Rule 8 has been causing problems hence this discussion.

Heya again

I just seem to remember at one time clicking on offsite links and seeing massive images submitted...mabey i'm just senile.

Anyways, if the size limit etc are the same, then i'm all for it...will save Knuk alotta work as well having to check his mail daily for reposts near the end of the contest.

Well, the weather never cooperated long enough for me to attempt a replacement image this month.. However, I just realized, the comments on my existing image were oriented around my first post(of the wrong crater) which I removed. Wondering if I could change that? I'm far beyond the self editing time, so I'm locked out..

Exactly (except that the new limit is 800X800 and 100K). Your off-site image *is* your entry and must be legal in every possible respect. The up side for this is that you can edit the image to your heart's content if you're careful not to break the link to the image in some way, and I like the idea that you guys can tweak things right up to the last if you want. The down side for the moderator is that it requires us to monitor these images closely to make certain they *stay* legal, but that is actually easier than changing out the images for guys who have run past the edit window - and as John has noted it promotes early entry into the contest.

PM sent.

In addition, I'd like to explain the current process a bit.
The only time that editing becomes an issue for me is when it occurs close to the deadline. I usually start working on the poll about a week before the last day of the month. That way I can get the poll up quickly after the close of submissions. Once I have started making up the poll, if somebody who submitted early changes their submission the number of steps to get the new image into the poll more than doubles. The probability of me screwing it up probably triples.

Well, I guess I am being hoist on me own petard!

There is only one submission in the DSO Challenge! I can only guess that there are going to be bunch of submissions while I am at WUTS. Looks like a busy Sunday afternoon, when I get back. Oh well.

Charlie and I have been discussing the idea of allowing the use of links to other sites. I see a consensus here that it is something the group wants to try out. Now would be a good time to voice objections, if you have any that you haven't mentioned.

I think the sky was too bright for the DSO challenge, clusters would work better in summer.

I don't like off site photos. I would rather scroll down and view all of the entrees at one time with out clicking and going back. IMHO

How about posting early, and if you have a better photo, then just add a new post. But only the last photo gets posted to the poll. The mods could delete the originals during the month, but I would like to see the progress as we get better.

The point of the contest is to have fun, and learn how to get better.

The NGC7023 was a great target for me. I have learned a lot about my DSI and it's limits. I have plans for a chiller to keep the signal noise down for long exposures. I'll start a post in the CCD thread, but this contest has shown me the weak point of my CCD.

Since each winner chooses the next (well, month after next) challenge, I think it will be hard to convince all the winners to choose only clusters in the summer. Also, why do you think the sky is brighter in the summer? AFAIK, there's not much difference if the moon is not up, other than fewer hours to image.

This can still be done with offsite photos. Contestants much use the UBB 'image' tag and point to their offsite image. The picture will still show up as an image rather than a link.

I'm hoping to still enter if I can catch a break in the clouds in the next few days. Not easy in Wisconsin

Here's an example image (my first Jupiter with my SPC900 from a couple of weeks ago!) using the UBB code. This image is actually stored in my google images folder, but you should be able to view it inline. Hopefully this will work from my google images folder:

Oops sorry about that. I think I pointed to a temporary google image. Look now- I moved it to a different server that I have more control over. Maybe Google won't be the best place to put these images...

I'm going to try with the google site again- would be nice if we could use google since it's free and huge. Let me know if you can see this image.



helps to include the link!
