Not sure about binaries...

EDIT: Nevermind.

This really cool exploration tool helped me find my second sheperd moon ever. I'm sure I went past several, scanned them and never noticed, but now I have something that tells me it is there.

 

[Baxder]

I just came across this little guy thanks to the app. It's so close that the rings drop you from orbital cruise. So freaking cool.

 

[Orvidius]

This one isn't quite as close to the ring, but still it was one of the first "oh cool!" moments that I found with the app that I would have missed otherwise. The moon was still close enough to the ring that I could watch ring particles moving by from the ground. Then I flew around to the night side and found brain trees, totally unexpected.

I've already sold the data. This moon is Plio Eurl YK-O d6-13 5 a

[herzbube]

At first I was skeptical, then I gave it a try, now I'm hooked. Thanks for making Elite Observatory!

 

[MattG]

Started playing with this recently. Found this yesterday that I'd have not bothered looking at otherwise

Spoiler

I started adding similar functionality to this to EDJPO quite some time ago... but I never got round to finishing it so I'm glad someone is more driven than me

I've added a pull request to add Telegram notification support - feel free to ignore it. This is also my first github pull request so be gentle if I messed up

 

[Vithigar]

Glad to have you along!

Ignoring a pull request is just bad form, I'd never do that.

I have problems to write my own Customs criteria... i need one for terrestial planets greater than 20.000 km, and one for terrestrial planets with more than 100 earth masses...

Looking forward to using this heading back to colonia over the weekend. Thanks for developing this, feels like I got a cool Christmas present already.

If you want to check for all terrestrial planet types you'll need to check the eventdata value for every planet class that you're looking for. You could use a chain of "or" criteria, or nest a bunch of addition operations, since you'll only ever have one planet class at a time that value will end up being 1 or 0, which you can then multiply against the radius or mass so that you only have a non-zero value on a matching planet type.

Hopefully that's enough to get you moving, but if it doesn't make any sense I can put together an example.

 

[MK Regular]

This one is sort-of possible currently. A planet can be landable with atmospheric pressure as long as it's under 0.001 atmospheres.

Huh, TIL.

Also, fun fact. The surface pressure of the sun is actually low enough (~0.00088 atm) that it would qualify as a landable body in ED while mars (~0.006 atm) would not

Is there any way to override the default "Wide Ring" criterion? It's set rather low for my liking and it's flagging all the time (1 ls is not a wide ring in my opinion).

The wide ring check isn't for >1Ls, it's for >5 * parent body radius.

But yes, you can override by disabling the check and creating your own custom criteria, or cloning the GitHub repo locally and building a version with whatever modifications you like.

I thought you said once that there was a list of the existing built-in criteria written in custom criteria format somewhere? Does that exist? I have to admit that right now I find the way that criteria are defined to be really unintuitive

Just to be completely unambiguous:
There is definitely not a list of all the built in criteria in custom criteria format. The built in criteria are written in C#, while custom criteria are in a janky xml format of my own creation. I have not taken the time to write xml versions of all the built in checks at this point.

If you need a new custom criteria written I can certainly try to help you with it. What would you consider a reasonable threshold for a wide ring?

I will also give an answer here because I think we are after the same thing really. The wide ring compared to parent body radius can give us some fairly narrow rings, I found a body of just over 1k klm in radius the other day with wide rings, they were around 50k klm across, and to me that simply doesn't fit what I am after. The widest rings I have discovered personally were 25m klm across, but rings plus 5m klm is the sort of base number I think of as a "wide ring" and I think that's the sort of thing Malenfant is after.

So we could have two criteria, a "wide ring to compared body radius" and a "ring wider than 5m klm." That's just an example of course, the exact width is not relevant, just that I also see a lot of unnecessary hits for wide rings but aren't matching what I want, but if I turn it off I may miss what I am actually looking for.

 

[malenfant]

Looking at what I've recorded so far, I've found 283 "Wide Rings", 262 of which are less than 13 planetary radii. There's a pretty sharp cutoff above 13.0 radii:

5-10 radii - 179 worlds
10-13 radii - 83 worlds
13-20 radii - 5 worlds
20-100 radii - 4 worlds
100-200 radii - 2 worlds
200-300 radii - 2 worlds
300-400 radii - 5 worlds
235035 radii - 1 (Neutron star )

All the ones above 13 radii (except for two worlds) were > 0.01 AU radius (5 ls).

From that I'd say 13 radii (or 5 ls) is a good cut-off for flagging Wide Rings (smaller ones are rarely interesting). I'd be curious to see if other folks' distributions are similar - do they get a similar cutoff at 13 radii?

I haven't broken it down exactly but that appears to be about right at a quick glance. Now I did mention my smallest ring, but I was way out, it was actually 0.03ls, 10k klms on a 1.6k radius body, my largest was 150.1 ls, 45m klm radius but I don't think I was the first to discover that. Yes above 5ls there's a big drop off in numbers.

 

[Orvidius]

Yeah, I've had the wide rings check turned off for a while, for the same reason. The wide rings I really want to find are the truly jaw-dropping ones. I've found a few in the past where the gas giant was several thousand lightseconds away, but the rings were already visible from entry (or nearly so). Truly massive. Those are the ones I'd like to be alerted to.
