Here is my latest image processing project focusing on the re-observation of the Rosette Nebula. As before, the data was collected using the fully automated astronomy robot, Vaonis Vespera Classic (Mark I), over the course of eight independent nights spanning from December 2023 to January 2024.

I am delighted with the final image, as both the resolution and color appear significantly clearer and more natural compared to my previous work with the DSLR (you can view it in my earlier post: https://youtu.be/wJPspAQANJI). This improvement is primarily attributed to the higher resolution of the Vespera, with a pixel size of 2.9 µm, as opposed to the 6.57 µm pixel size of my old camera. Also the effect of narrowband filter was also contributed a lot for this pleasing result.

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.
