Re: Astroart 7
I am using Astoart6 for almost a year now and I have to say it is just fantastic.

Re: Astroart 7
Hello, the jagging is correct in integer mode, as shown in the graph every step is exactly 1 ADU, which is the best resolution for an image in integer format.
For fractional values, you should work in floating point. But I wouldn't do that considering that a typical CCD image has a random noise of 5-10 ADUs.

As another solution, if you need to reuse that synthetic flat field for the future, you could multiply the image by 10 or 20 before the filter, so that the dynamic is higher. This is valid only for the option "Create flat field".
Instead, if that option is not enabled, the flat field is used internally in floating point, so no defects will be visible in the corrected image.
