Ich habe die Feuerrad Galaxie am Ostersonntag 2023 fotografiert. Etwa 7 Wochen später, am 27. Mai habe ich die Galaxie nochmals mit dem Optolong L-eXtreme Duo-Schmalbandfilter fotografiert. Ich habe hieraus den Hα- Kanal extrahiert und mit den RGB Daten verrechnet. Dabei ist mir ein kleiner weißer Punkt in einem der äußeren Spiralarme aufgefallen. Ich habe es zunächst für ein Stacking-Artefakt gehalten. Ein Gespräch mit einem befreundeten Astrofotografen und ein Blick ins Netzt hat dann die Gewissheit gebracht. Es handelt sich hierbei um die Supernova mit der Bezeichnung SN 2023 ixf. Ich war sehr überrascht aber auch froh dieses Ereigniss eingefangen zu haben, Die gesammelten Hα-Daten sind mit 3h noch nicht ausreichend. Daher habe ich im finalen Bild bisher nur die RGB Daten verarbeitet ohne die Supernova.

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.
