Well, I attempted a 3-panel mosaic of M33. With a setup at f2.9, the task was not easy...

The idea was to use a UHC-filter to bring out a lot of nebulae, because it's the main interest in this object in my opinion. I wanted to do 3x8h of shoots, but the weather only allowed me something like 3x3h, so the background stars and the faint nebulae are not totally there.

Furthermore, i had some trouble in merging the left pannel with the other two, as you can see, the background is not totally even. The problem is that the moon was bigger on that night, therefore the background correction was harder to do. There is a bigger amount of noise as well... which is a pity since it was by far the best night of the three seeing-wise.

Overall, i'm still pleased... it's my first mosaic so i've more to learn !

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.
