Tidal action of the Mice Galaxies (NGC 4676)

NGC 4676, known as the Mice Galaxies, are two spiral galaxies in the constellation Coma Berenices, approximately 290 million light years from Earth. The long tails result from tidal action — the relative difference in gravitation pull on the near (colliding) and far sides of the galaxies. The galaxies are incredibly dim and small, providing quite a challenge from our light polluted skies outside of Bangkok.

This image was taken with our Officina Stellare RiLA 600 f/5.0 telescope on an Officina Stellare direct drive polar fork mount. An FLI ML16200 CCD camera, chilled to -25C, captured 16-1/2 hours of luminance detail and 9 hours of color detail. The imaging system is controlled using Voyager software. Image processing in PixInsight and Photoshop.

Imaged and processed in Samphran, Thailand by the SC Observatory team: Mike Selby, Andy Chatman, Stefan Schmidt.
