Hai-Nebel - Shark Nebula - LDN 1235 und LBN 541 u. 546

LDN 1235, LBN 541 und 546 (bzw. vdB 149 und 150)
Für die schwachen Objekte ist ein sehr guter und transparenter Himmel erforderlich, daher habe ich meinen (Astro-)Aufenthalt auf La Palma im Oktober 2023 genutzt, um diese zu fotografieren. Das Objekt trägt auch den Namen "Hai-Nebel" der mit etwas Phantasie auch gut zu erkennen ist, wobei die Reflexionsnebel vdB 149 und 150 dabei noch einen schönen Kontrast bilden. Auch ein paar Galaxien sind im Feld zu finden, u.a. UGC 12003.

Es handelt sich um ein Ergebnis aus zwei Nächten. Es kam kein Filter zum Einsatz.

LDN 1235, LBN 541 and 546 (or vdB 149 and 150)
A very good and transparent sky is required for the faint objects, so I used my (astro) stay on La Palma in October 2023 to photograph them. The object also has the name "Shark Nebula" which can be easily recognized with a little imagination, with the reflection nebulae vdB 149 and 150 forming a nice contrast. A few galaxies can also be found in the field, including UGC 12003.

This is a result of two nights. No filter was used.

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.
