HDR Composition Problem. Can someone Help?

[ajbarr]

I have 5 fits files, calibrated and stack all with different exposure times. I have tried to run HDR Composition on them several times and I keep getting this error message:

"Inconsistent HDR composition detected (bad linear fit, Channel 0)"

This has never happened before. Can someone advise me on how to deal with it?

Thanks

Hi Albert,

I am sure you have probably checked this.  If not, please make sure that all images have the same number of columns and rows.  If those are all the same, are you able to HDR combine only two or three of your base images.  My thinking is that maybe only one base images are the source of your problem.

Cheers,

Don

Thanks Don. You are probably right but I couldn't find the culprit. So I stacked three shorter exposures together then stacked three longer ones and ended up with two fits files. I did a star alignment on the two files then ran HDR Composition and it worked. I later ran HDR Wavelets on the combined file and it worked beautifully. The Trapezium in M42 is perfect.

Thanks again

Albert
