The Witchhead Nebula and Rigel from Lizard Island

Here I have pointed towards zenith on an object I can see from Sweden but which is usually too low on the horizon for getting a good image. This is a 2-frame mosaic so I could fit in both the Witch and Rigel shining on her. 90 s exposures on the Witch and 30 s ones on Rigel. I really doubt I can get this deep on the Witch from back home, and I had almost none of satellite trails that mess it up when shooting at it from Europe. One challenge was of course to tame Rigel. For the first time here on Lizard Island I had a gradient issue, but not from light pollution but from Rigel, so natural in a way. Dynamic Background Extraction in PI did a good job on the gradient.

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.
