The second more or less clear nights in a row. Time to try my first astro mosaic shot made out of two panels. In addition to the sisters, their two parents Atlas and Pleione also made it into the picture.

Both panels have 50 180 seconds exposures each. For the stitching I first tried Photoshop, PixInsight didn't really convince me with the workflow either. Stitching in daylight is actually way easier. With Alcyone's long spikes in the centre, it's noticeable that it didn't work perfectly, but fair enough.

As nice as the square sensor of the 533MC is, and as forgiving as it is for slight misconfigurations of the optics (because they are simply not part of the image), you do wish for a sensor with a 3:2 aspect ratio from time to time.

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.
