Stack and align

Post by David Cejudo »

Hello.

I have a question about how Demetra handles the stack process.

After extracting the spectrums, the next step is to stack them. My doubt is wether Demetra does an alignment of the spectrums or it just stacks them without alignment.

In case of imaging the same object during the whole night, the first and last extracted spectrums will probably be missaligned, even if slightly.

Thanks.
