virtual sky not showing ? also no startrails

[stuartsmith-nasstar]

ignore - no startrails bit - i fixed that but can't seem to edit topic above.

sorry chaps if this is obvious but I've been through settings and discussions - I assume something stupid.

my config:
{
"comment": "See https://github.com/thomasjacquin/allsky/wiki/allsky-website-Settings for a description of
these settings",
"id": "starmap",
"meridian": true,
"ecliptic": false,

"showgalaxy": true,
"galaxywidth": 0.75,
"live": true,
"lang": "en",
"objects": "virtualsky/messier.json",

}

but no overlay showing (even set it to 1 as you can see). have I not turned something on I should ?

Also - got a new build - will post pics soon

@stuartsmith-nasstar, for the startrails you need to play with the threshold. Anything image whose average brightness is ABOVE that value is ignored, like daytime images. I stretch my images and set the threshold to 0.2. See also the Wiki page on startrails.

For the overlay, there are two configuration files: config.js and virtualsky.json. If either has a syntax error, like a missing comma, the overlay won't appear. In your browser press F12 to get into "developer" mode. On the top right side click on "Console" (may need to first click on >>>), then refresh the page and display the overlay. Any errors will appear in the Console.
If you can't find the problem, please ATTACH the two configuration files, do not copy paste their contents. You will need to append .txt to their names first.

When you say 'and display the overlay' this suggest I am in fact doing something stupid... this is on the live view page yes ? I don't see any 'display overlay' option. should I ? Or when you say 'display the overlay' do you just mean look at live view ?

nothing obvious wrong in files I can see.
configjs.txt
configsh.txt
virtualskyjson.txt

I am not suggesting you are doing anything stupid and hope you didn't think I was.
"display the overlay" simply meant to click on the Casseopia icon on the left side (the top icon), which displays the constellation overlay.

[stuartsmith-nasstar]

OK ignore me.. I did not realise that the 'website' is on /allsky. I just assumed it was the images tab of the admin gui.

I told u it was something stupid!!

[EricClaeys]

Ah, ok. The WebUI is the page with all the links on the left side, like "Live view", "Images", Camera settings", etc. It is usually only used by the person who owns the Pi.

The AllSky Website is an optional package that shows the latest picture and can show a constellation on top of the pictures. It is often on a separate server that can be viewed from the Internet.

So next issue though, is that after an hour of faffing I can't get the overlay to match up. I'm using the regular asi120 allsky lens. I think it's about 120 degrees fov. IF I could make the overlay maybe 4000px or so it might line up, but otherwise not a chance. I've tried other projections. It seems like ideally it needs a field of view in degrees projection option. I'm sure this must affect others? Is there a hack?

@stuartsmith-nasstar, getting the constellation overlay to be on top of your stars is a hassle.
Take a look here.
If you find an easier way let me know.
