I have uploaded an image. This could not be platesolved with astrometry in astrobin. However, I have solved the same image with Platesolver 3.0 within a few seconds. Has everyone an idea, why this happens?
Why astrometry failed but Platesolver 3.0 succeeded on same image
Try resubmitting
Resubmitting for platesolving does not help. The problem is a little bit more complex. I have made the first image only with Pixinsight (Weighted Batch PreProcessing). The result is an image with a little bit green-yellow background. This image I have uploaded at first to astrobin. The astrometry as well as platesolving with Pixinsight in Astrobin was done very fast. As the colorisation of this image was not, what I expected at the end, I have prepared a second image with the same data. However, calibration and stacking was done with Astro Pixel Pocessor. This second image I have then uploaded as version of the first image. The astrometry with this image fails several times up to now. Platesolving this image with Platesolver 3.0 comes with the result within a few seconds. The question for me is, why Platesolver comes with the result but platesolving in Astrobin cannot resolve the image.

Are you submitting/uploading a fits file or a xisf file. Or is it a bitmap. Also, try directly https://nova.astrometry.net/
Hello, I tried to submit the resulting *.jpg file to upload directly to Astrometry, The reslut was the same; not solved within 10 minutes. After this I have tried to upload the fit output from PixInsight before I did the final corrections with Capture One an Photoshop. Then the Image was resolved. Probably this is a problem of the removing internal image data when exported to a *.jpg file.

Probably the problem is deeper than just the image format since I routinely use bitmap files both here in AB and in astrometry.net and they all work if enough stars are showing.
I thonk there are enough stars in the image. in Platesolver 3.0 are 97 stars used (94 matched) and solvong was done within 5secondes (strecked fit image). Astrometry.net needs less thau 60 seconds for the fit image. I will now export the fit image from Pixinsight (no additional finalization with Capture one and Photoshop). and look what happens.
Ok, the image direct from Pixinsight was solved with both methods within a few seconds. Probably the final process with Capture one (mainly black point setting) and Photoshop (reducing contrast) makes the touble.
That is what I thought…
