Bon, cette soirée du 17 février 2021 était destinée à tester la collimation du 200 que je ressortais pour l'occasion et j'avais coché dans ma liste de cible à aller voir un couple de galaxie en interaction, j'ai du attendre qu'elles montent un peu dans le ciel et qu'elles passent au dessus de mon toit (en attendant j'ai fait quelques poses sur Barnard 33)

au début, j'avais installé une barlow x2, beaucoup de difficulté pour faire la MAP, je me résouds à enlever la barlow et commencer l'acquisition.

alors, comment dire, c'est pas la photo du siècle. ouais bon un, j'voudrais vous y voir :-)

étant en congé, je voulais passer la nuit dessus, vers 2h30, j'ai du me résoudre à arrêter l'acquisition -> buée sur le correcteur de coma !!

beaucoup de gradient aussi qui a rendu le traitement pas simple

au fait, la collim, pour finir, n'était pas glop, au cheshire elle paraissait pas mal pourtant, un petit coup de laser avant de finir d'installer la caméra, petit test de défocalisation sur une étoile -> j'ai encore du travail sur la collimation

quand je vous disais que ce n'étais pas la photo du siècle

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
