Can not calibrate Images captured with EKOS (stellarmate) in Pixinsight? was created by fusis

Hi!

I captured my first images with stellarmate. But when I load the images in Pixinsight I get this message:

** Warning: The FITS format does not define an unambiguous orientation of pixel data. The coordinates read on the image may be wrong.

I can view the image just fine but then when I try to calibrate the images I get: *** Error: Incompatible image geometry

Can someone please give me some directions on what to do? Am I missing something?

FYI: I am using ASI294MC Pro Camera, I added 1 captured file, so you can check if you like.

Thanks,

Marco

I think the fits warning is normal. Pixinsight tries to push you to use the xisf file format over fits for the reason described in the error you got.

If you are trying to calibrate with Cal frames captured with a different tool than ekos the incompatible geometry error can happen. This has to do with how different drivers read out the camera. Try grabbing some Cal frames within ekos.

This is interesting.. I wonder if this has to do with the FITS data read as top-down or bottom-up. Can you please open this same topic in the PixInsight forum and I'll follow up with you there?

The Calibration frames were also taken in ekos. Flats and darks.

This may be helpful:

pixinsight.com/xisf/#Why_XISF

Regarding the geometry error - frames pulled via indi w/ Ekos and other clients (PixInsight included) are definitely different than those captured with TheSkyX on Linux (incl RPi) for at least the FLI drivers. As an example I get overscan margins w/ indi but not with TSX. It's probable that other cameras are similar. I wouldn't be surprised if this is the case.

PixInsight will error if the image geometry (matrix size, possibly pixel depth too) is not exactly the same between the calibrating frame and the frame to be calibrated - they can't line up.

Same binning? No subframe?

If all the images are taken in Ekos with the same settings then it shouldn't be an issue. Let me try with PixInsignt here in just a sec.

I would submit one of the flatfiles but it's too big to post... you want me to e-mail it?

Hi
Siril has a workaround for it:

I was kind of hoping a similar setting would be available to be set in Ekos.

If there is none, then how would I go about and change te fits files (in batch) to be compatible?

Just to add, I use same binning, etc.

And what's more, the flats and darks do not give me: ** Warning: The FITS format does not define an unambiguous orientation of pixel data. The coordinates read on the image may be wrong.

So it's just the lights that seem to contain the unambiguous orientation data.

Hi
The flat and dark frames are not debayered before stacking. You the combine them with the light frames which are.
