Cygnus Mosaic artemis ii NGC 1300's arms twist away

NGC 1300's arms twist away from the ends of a straight bar of stars that stretches across the galaxy's core

Our total integration/exposure time for this image is about ~90 hours and we split this time up into 250 individual panels (which have been merged from over 5000 single exposures)

It is thanks to this phenomenon that every year we can observe Perseids in the sky

Cygnus Mosaic artemis ii NGC 1300's arms twist awayThis ambitious project began in mid to late March 2023 when I conducted automated mosaic tests with my newly installed remote telescope at e EyE in southern Spain. However, let's rewind a bit: I've always been captivated by large images, whether they're expansive landscape panoramas or deep sky mosaics with a broad field of view. Last year, I closely followed Bray Falls as he set up his new telescope rig for such images; a Takahashi FS Q 106 with a
