Hi Vincent, it's near a star, so maybe that's the problem and yes it's faint. I have to confirm almost every frame. See my pasted image. I will load up the dataset but how do I have to do this?
Vincent, this is the final registration. It worked fine. Can you tell me from this streched image of this is due vignetting or light pollution? I use flatframes.
Kind of looks like vignetting, are you sure the flat frames are correct and applied as well? I'll have a look at the data as well, so can probably tell. Light pollution is also possible, but you'd have a lot then indeed. The LP tool should work pretty well on it.
Loading in the lights I noticed in the FITS header that the mosaic type could be different to what is reported. Which is kind of odd to me. I changed it manually to RGGB and that looks better, otherwise the blue channel was more pronounced which didn't make much sense to me.
It indeed does involve a few manual actions, but it also processes quite a few automatically. I think the data is somewhat on the borderline of what the algorithm can nicely detect. Nonetheless, always perfect for trying to optimize it.
So yes, the flats do have an issue. Not all dust spots are removed and it's over-correcting. This usually is the case with either a bias or dark not being correct or an issue in the flats.

I use Sharpcap Pro and in Sharpcap I can click on Inverted. Sharpcap suggest that this is for APP. Is reverse the bayer. Is that what you are saying?

Ah how interesting, never seen that before. When I loaded in your data, the standard pattern as reported in the fits header is used and that was showing GBRG. Which I overruled manually to RGGB in tab 0. I guess the setting in Sharpcap will do that then.
What do you suggest I do to get correct flats? Bias and darks are from last month.
That depends on how exactly you're taking them. What procedure do you follow exactly and what program do you use to capture it. How are you taking proper bias and darks..
