After stacking 499 pictures at 135mm, I noticed that there was something weird in the head of the comet. Could this be the nucleus or?
Is this the comet nucleus or?
This is a stacking artifact. The nucleus would just show as a tiny dot similar to a star, given that it's not entirely over-exposed that is.
EDIT: Judging by the image I take it that you have stacked it the normal way by aligning on the stars, not the comet core?

It is normal stacking using siril

Ok, that's how the artifact has been created. The comet has become streaked, much like stars streak if you don't track when imaging, and the rejection algorithms have also rejected parts of it which is why the dark area is present. So this stack will only serve as a star layer, in order to get the comet properly aligned you need to go through a series of other steps as well. I only use Pixinsight, but maybe this info page by Siril will be of some help to you: https://siril.org/tutorials/comet/

Strange persistent structure/artifact in old (2025) subs — what could it be?
Hi everyone, Quick (and kind of funny) question. I revisited some March 2025 data of the Dolphin Head Nebula—only 13 × 180s frames. A few days ago I resumed the project and decided to register/align those 2025 subs to my new 2026 data so I could comp...

Strange moving object in Dolphin Head Nebula data
Hi All, I was just going through some recent data I have acquired on the Dolphin Head Nebula (Sh2-308), and while blinking through the data I noticed this weird spot that kept bouncing erratically around in my subs. It shows up in slightly different ...

Did I caught a meteor train?
While processing frames of comet C/2025 R2 (SWAN) taken with a Seestar S50, I noticed an unusual feature on three consecutive frames. It doesn’t look like lens flare to me. Could this be a meteor train? Exposure: 10 seconds each Frame times: - 19:59:...
