Every year, when it becomes available, I can't help but aim my rig at this big target, every time hoping to get something more, of doing something better.

I used again the EOS 1300D for the first time since I bought the 2000D about a year ago, in part to avoid unmounting the clip filter on the 2000D, in part because it has less pixels and creates smaller files, in part because it is unmodified and hence it should be easier to white balance.

Unfortunately, after having been left dormant for so long, it had many speckles and spots on the sensors that flats couldn't properly fix, so I had to do some "cut and paste" to cover imperfections.

Some star elongation is visible, particularly on the left side, which means the imaging train was not perfectly symmetric.

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.
