Description

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.
