Jurgen Landrie Posted June 5 Share Posted June 5 Hi, When trying to use plate solving, as explained in the tutorial video "PLATE SOLVING AND PHOTOMETRIC COLOR CALIBRATION IN SIRIL", I always get the message: "When trying to plate solve, I always get the message: "Plate Solving Failed. The image could not be aligned with the reference stars." Any clues on how to fix this? Thanks in advance!! Link to comment Share on other sites More sharing options...
Alexander Curry Posted June 11 Share Posted June 11 Hi Jurgen, At what point in your workflow are you performing the plate solving? Link to comment Share on other sites More sharing options...
Jurgen Landrie Posted June 19 Author Share Posted June 19 Hi Alexander. I tried several points. Usually I do it right after the initial stretch, following the workflow in your latest Siril Tutorial. Sometimes it works, sometimes in doesn't. More not working though. Link to comment Share on other sites More sharing options...

Are you having issues with certain datasets, narrowband for example? If you could send more screenshots of the settings (including dataset information) of the plate solving we can see what parts are potentially missing Link to comment Share on other sites More sharing options...
Jurgen Landrie Posted June 22 Author Share Posted June 22 (edited) Hi Alex, So, on this one I took M1 as an example. Taken with the SPA-2-CMOS. First you see my initial stretch (quickly done, could be better, but it's just to get the idea) Second screenshot are my settings for plate solving. Third screenshot is the error message that pops up. The same happens with M51... I also have no idea why it keeps using the local catalogue...

ERNESTO GUIDO Posted June 22 Share Posted June 22 Hi Jurgen, Just a note about the resolution: SPA2-CMOS telescope was working with bin4, so the resolution for this dataset is 0.55"/pixel (instead of 0.138 I see in your screenshot). Clear Skies, Ernesto Link to comment Share on other sites More sharing options...
Jurgen Landrie Posted June 22 Author Share Posted June 22 Hmmm but I can only put in the the Focal Length and the Pixel Size? Link to comment Share on other sites More sharing options...

You should change the pixel size to 4x (equal to the binning) the size. As this is now the "new" pixel size when binned To your earlier comment, the local catalogue is used when installed as it's much faster than running through the internet.

Jurgen Landrie Posted June 22 Author Share Posted June 22 (edited) Oh gosh!!! This did it .... Thank you so much both! Maybe it's worth mentioning in your tutorial about plate solving to first set the correct info in "Image Information -> Information" And not setting in the plate solver dialogue? So glad we got this sorted!! I still have a few questions about initial stretching, but I won't bother you too much 🙂 Edited June 22 by Jurgen Landrie forgot something 2 Link to comment Share on other sites More sharing options...

So glad we got this sorted!! I'll review and update accordingly. Glad we got it working! 🙂 1 Link to comment Share on other sites More sharing options...
