Thanks guys, if that's the case then I'm forced to bin the lot and try and get the object again in a couple of weeks time.
Appreciate again your time and efforts.
Cheers.

Hi Bernd,
The image I dropped into dropbox was an original, straight from the camera which is a QHY8L using EZCAP as the preferred software for that camera.
The images were taken in 2016 (from memory as I don't have them in front of me at the moment) but now that I think about it I had an issue with calibration files not being the same geometry as the original images so that is more than likely why the the FITS were written by PI.
So I would have tried to calibrate them without success so was forced to alter the dimensions of the originals to that of the calibration files. I wouldn't have thought that would cause the lines but it might explain the dark edges.
Sorry, I should have remembered that but the issue still exists at the very start of the processing procedure.
Cheers.

Well the mystery just deepens because these images have never been in PI, they just sit in a folder on my laptop waiting to be processed.
I'm thinking that I might just need to bin the lot and wait until next summer although March in a couple of weeks is an option.
It's frustrating that's for sure.
So if you're out of options then I think I might just do that.
Cheers.

Forgot to add, I tried your suggestion of debayering before cosmetic correction was applied with the same result so it appears that the fault is right at the beginning. I took a single original image and applied debayer to it with the same result.

Hi Rob,
No, the camera saves it as a fits file, I just checked all my other images that are waiting to be processed and they are all fit files if that's what you mean.
These were taken in 2016 and I haven't, to the best of my knowledge, updated the software for the camera. The laptop I use is kept with my gear and I only image remotely where there is no internet available so no auto-update availability.
I might try and see what happens if I try to process subs from last year and see if I get the same result.
Cheers.

Hi Chris,
The link to the dropbox is https://www.dropbox.com/s/0tv07xkz7oiaa1f/HorseHead-1-600s-8-C0.fit?dl=0
Hope that works, I haven't used it before, if not let me know.

I'll try your suggestion this afternoon Rob.

Cheers.

Hi Rob,
I'll try giving the CC process a miss and see what happens then.

Hi Chris,
I'll drop one of the original subs into dropbox over the weekend. It's going to be stinking hot here so a perfect time to sit in the AC and do some processing.

Cheers.

Hi Rob, no, the process was cosmetic correction of all subs, debayered all subs and then registered them hoping that ABE or DBE might help resolve the problem.
I might have to go back to square one and start the process again. Even if the debayer matrix was wrong I don't think it should have done that to the images.
Cheers.

This is the second image Rob.

Hi Rob,
So I've uploaded the stretched images (I hope) over two posts as I keep getting an error message that they are too large. You should be able now to see what I'm on about.
Cheers.

Sorry Rob, I forgot that they don't save stretched. I'll repost it when I get a moment.
Cheers.

Hi all,
Attached are images of the Horsed Head, one is after cosmetic correction has been applied and everything looks okay the other is after the debayering process has been applied. The problem should be obvious.
I've never had this occur before and I was hoping subsequent processing would remove the lines and gradients (if that's the correct terminology).
All images were taken with a OSC QHY8L, calibration files added.
The debayer matrix for that camera is GBRG which was applied and has successfully been applied in the past.
I tried all other debayer combinations but they all gave either the same result or made the same result worse.
Blink did not give any indication that there was going to be an issue and even when I applied the debayer process to just one sub the same result occurred.
Is there a problem here or will this effect be removed later in the processing procedures. I have already tried DBE and applied ABE afterwards both of which took out the vignetting but the lines are now more obvious.
Regards, Steve.

Hi Rob,
Many thanks for your help, I'd be tearing what little hair I have left out by now as that is not what I would have expected.
I don't change the settings on the camera like that (not even sure I can or how to) but a system upgrade is quite possible.
Anyway, you've got me on my way so I appreciate you taking the time to help me.
Cheers.

Hi Rob, So I again ran the batchstatistic script over not just the calibration files but also the images I'm trying to calibrate them with and there's a difference in the size. The calibration files are 3040","2016","0","0","1", "3040","2016","0","0","1", "3040","2016","0","0","1 and the subs are
"3328","2030","0","0","1"
"3328","2030","0","0","1"
"3328","2030","0","0","1"
"3328","2030","0","0","1"
"3328","2030","0","0","1"
"3328","2030","0","0","1"
"3328","2030","0","0","1"
"3328","2030","0","0","1"
"3328","2030","0","0","1"
"3328","2030","0","0","1"
"3328","2030","0","0","1"
"3328","2030","0","0","1"
"3328","2030","0","0","1"
"3328","2030","0","0","1".
I think this could be the problem which you have alluded to. I will try to change the size and see if that makes any difference.
Cheers.

Hi Rob, okay so I ran batchstatistics over the calibration files that I've been using, I've attached them but I'm not sure how to interpret them.
The width and height are easy and all are the same, the channels though are throwing me.
As you can see each channel is 0, 0, 1. Is that normal?
I don't use mono, the only camera I own is the QHY8L so all images including calibration files are taken with it.
Cheers.
