Hi, 

Is this site running only for now as a temporary solution, or it is something that always runs. Can it be used as a reliable option in the code when the main site is down? Thanks

[Dustin Lang]

It's only temporary.

Hi Dustin

Still, I face problem to obtain wcs image from http://nova2.astrometry.net/status/127

Please see the attached screenshot. It says job failed.

thanks

That means we weren't able to match your image with a known place on the sky.

Questions:

- what are the blacked-out features in your image?  It looks like you have done something weird to this image.

- I see that the file is called "fakesky.fits" .... is this an actual image of the sky? :)

Hi,

I tried resubmitting your image but setting the image scale to 10 to 12 arcmin across, and I got this solution:

Hi Dustin

Thanks for your response and for resolving the issue.
How did you change the image scale from 10 to 12 arcmin?
Did you change in the image (fakesky.fits) header ?

I would like to try by myseflf and see if I can get the wcs.ftis image from fakesky.fits (pixels coordinates).

thanks and regards
eswar

[Eswaraiah Chakali]

Because, I tried once again with the old header in the fakesky.fits but again endup with failed status

Hi Dustin

I would be grateful if you can help in converting sky images to those with wcs.

Please find the attached images. The problem I am facing might be because of poor seeing.

Most of the image I have converted are with better seeing (fwhm of the stars = 4-5 pixels).

The attached images are with poor seeing (5-7 pixels of fwhm).

You mentioned that possibly by increasing the image scale problem can be overcome. Please let me know how to do that if possible.

Thanking you very much

On the nova.astrometry.net/upload page, click on 'Advanced Settings', under 'Scale' select 'Custom', set units to 'width of the field (in arcminutes)', and range 10 to 12 arcmin.

I will try with your suggestions.

Hi Dustin

Thanks a lot. It seems 10 - 12 arcmin scaling limits work for few images.
Even after setting the scaling limits 9 - 15 arcmin I still failed (10 - 12 arcmin doest not work) to obtain the wcs image for one image.

If you look at the Source Extraction image,

http://nova.astrometry.net/extraction_image_display/2109712

you will see that you have not sufficiently masked the duplicate stars, because they are detected (shown with red circles).
