Hi all,
A friend of mine has bought a 2nd hand QHY10 and would like
to apply the correct debayer mask for it.
Aparently ( as he states ) this is not in the dropdown list for
the specific bayer masks one would like to apply.
Any suggestions I can pass on to him? ( he also has APP license
but is not "handy" in English .
Thanks for any tip!!
Mert
Dear @Lammertus,
If the sensor is a Bayer CFA sensor, then APP provides all 4 posibilities as stated on wikipedia for a Bayer CFA sensor
https://en.wikipedia.org/wiki/Bayer_filter
Has he tried all 4 posibilities that APP offers ?
If you or your friend think, it's not correct, you are welcome to send a frame so I can check.
Maybe it's also good to verify the image dimensions ( widthxheight) and which software is used to capture the data.
Some capture software do some weird output of the sensor, at least I have seen this before...
Cheers,
Mabula
Thanks Mabula,
I will try and see ( when the rain goes away ) that we do as you suggested.
Basically he images using the software for the QHY, I think EZcap?
I will let you know!
Best regards,
Mert
Hello Mert,
Maybe I can help. I do not have a QHY10 camera, but I used to image with a camera with the same sensor (SXV-26C).
I have used BGGR as the deBayer setting (and set it to "force CFA"). I found this by trial and error. I first started with RGGB (as this was in the manual) and worked my way down. First look at the color of your individual subs (does not have to be calibrated, just set the deBayer setting and double click on the image in the list). Look at the image. Is the color more or less what you would expect? I almost always have a green background, but that is OK. I live in a light polluted area. The star colors and the object colors need to be there. Secondly, zoom in and look for strange raster patterns. Should not be there. If yes, then try another deBayer option. If I can remember correctly, I had two settings that looked OK color wise, but one showed a raster pattern, the other did not. Do not forget to double click again on the image after you change the deBayer pattern to see the changes.
Good luck,
Anne
P.S: You can test this in daylight as well...
Thanks Anne, apreciate your feedback!
I will advise my friend to check on this, likely it is just nervs since he
just got the camera!
Best regards,
Mert
Hi @annehouw & @lammertus,
Thank you Anne for helping out as well 😉
Indeed, probably the Force Bayer CFA needs to be turned on and then simply check the bayer patterns by double clicking an image after a Bayer pattern change 😉
Please let me know if all is allright,
Mabula
