@jinouss you could try this out since you are good at Siril processing,@DILCHSKY ,@StuartTheAlien👽🖖 in case you didn't already try this target with your telescopes

The reason? Simply because using a external battery will give the Seestar enough energy to shoot for the whole night instead of only 3-4 hours.

After gathering as much light as possible, stack separately each of the panels in Siril or the app, and no matter what your astrophotography skill level is, do your best to process them with any astro software like Siril, PixInsight, GraXpert, Cosmic Clarity, Astroforge etc. After that, assemble your 6 panels with Microsoft ICE, PixInsight, Google Photos if you don't care about anything, or any other software you like.
