An oldie-but-goodie…this was unguided (hence the misshapen stars). Nonetheless, Annie's Astro Actions once again proved their worth:
Southern Pinwheel Galaxy, 2018-05-04, 53˚ elevation
Canon 200mm f/2.8L II@f/3.5, Canon T3i (unmodified)
8×120 sec@ISO 400, no darks or flats
Skywatcher SkyView Pro EQ Mount (unguided)
Aligned & stacked in Lynkeos 2.10
Processed in Photoshop CS5 w/Annie's Astro Actions v7.0
Full sensor scale, cropped to 1600×1067
Tropic of Capricorn, NT, Australia
Cheers, Annie!
