Description

AAPOD² du 24 octobre 2018

Tentative de mise en évidence du noyau de la comète 21P Giacobini-Zinner.
Image traitée : empilage de 20 poses de 60s L bin 1 alignées sur la comète.

Traitement par gradient rotationnel.

Il me semble qu'on distingue clairement 3 jets, en plus de la trainée de la comète.

Attempt to show the core of comet 21P Giacobini-Zinner.

Stack of 20 images of 60s L bin 1, comet alignement.

Rotational gradient processing.

I think that 3 jets are visible.
