No it is correct. I dabble in astrophotography.

The purpose of stacking hundreds of photos is to get rid of noise and unwanted trails like this.

The effort involved here is to go out of your way to do the exact opposite, specifically make sure things that are in a single exposure show up in the stack.

Somehow you also seem to be missing the point.

You stack photos to enhance clarity and remove noise. Your work is not "mendacious".

But what you are removing is still data - and as you can see, some people find it to be very interesting.
