Galaktische Nebel IC 59 und IC 63 in der Kassiopeia

Diese beiden schwachen galaktischen Nebel sind eine extreme Herausforderung für Astrofotografen, liegen sie doch nahe bei dem hellen Stern Gamma in der Kassiopeia, der fast immer für eine starke Reflexbildung im Strahlengang des Aufnahmeteleskops sorgt, sofern man nicht ein Spitzenequipment (z. B. Komakorrektor, Filter) mit sehr guter Vergütung der opt. Oberflächen benutzt. Zudem sollte man seinen Newton für ein optimales Ergebnis eigentlich von innen mit Velourfolie auskleiden, Fangspiegelkanten schwärzen usw. Gamma Kassiopeiae ist auch für das Leuchten der Nebel verantwortlich, die hier als Emissionsnebel (rötlich) aber auch als Reflexionsnebel (bläulich) zusammenwirken, je nach Abstand zum strahlungsintensiven Stern Gamma. Ich war aber froh, sie zumindest in der hier gezeigten Form auf den Sensor meiner EOS 1100 Da gebannt zu haben, denn die Nacht war vergleichsweise sommerlich warm, was das Rauschen der EOS nicht unbedingt positiv beeinflusste.

Description: Neubearbeitung mit PS CC 2019 (selektive Anhebung des Kontrastes des Nebelgebietes, der Farbsättigung sowie Optimierung des Himmelshintergrundes). Mein damals verwendeter 2-linsiger Komakorrektor sorgte für einen unschönen Lichtreflex im Aufnahmefeld, den ich nur mühsam mittels BB halbwegs beseitigen konnte. Derartige Reflexe sollten mit meinem neuen Komakorrektor (multivergüteter 4-Linser) erwartungsgemäß der Vergangenheit angehören.

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.
