Barnard 33 Horsehead Nebula

After more than 6 weeks of clouds we had one night without any cloud. Seeing was fair, it was cold and dry. Perfect night for the horsehead nebula. The position in the sky is really good in january, though IC 434 will never rise more than 35° in my spot. Everything worked fine until i realized (while postprocessing) that a huge reflection of the spider came from the nearby bright star Alnitak. Damn. Don't know where this comes from? Version B shows the uncropped image where you can easily spot the reflection. There is another problem: My PI-skills are not good enough to reduce the noise in these large nebula-areas, so dont zoom in or you will see a lot of nasty noise :-(

Nevertheless i am somewhat happy with this image. I can learn a lot from processing it and i am sure i will add new versions in the future.

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.
