NGC 1291 and its Dwarf Companion
NGC 1291 is a well-known ring galaxy that has an unusual inner bar and outer ring. It has been imaged and described many times, but its elusive dwarf companion has been ignored. My main mission was to capture this tiny object. And there it is! To the lower left of the main galaxy.
NGC 1291 meets the requirements of the Catalog of Southern Peculiar Galaxies and Associations, by Halton Arp and Barry Madore. It satisfies Category 8-galaxies with apparent companions, and Category 20-Dwarf Galaxies (Low Surface Brightness).
Tech Notes for ASA 500/3.6:
ASA Newtonian, 500 mm aperture, 1900mm focal length, F3.6
FLI Proline 16803, 9 μm pixel, 4096 X 4096
ASA DDM85 equatorial mount
Processing with PixInsight, StarTools, and Affinity Photo
