NGC 1291 stands out with its distinct morphology and attractive outer ring structure that makes for an eye-catching spectacle in space. Astronomers love studying this galaxies because its outer ring has an approximate diameter of 65,000 light years - making it one of the most visible galaxies ever. NGC 1291 belongs to a double bar lenticular galaxies category and features a similar outer structure including an outer barlens with central bulge that surrounds inner bar. NGC 1291's outer barlens is connected with this outer barlens via outer barlens; further distinguishable features include connecting outer barlens-connected to an outer barlens - connecting back into its core galaxy structure!
The outer ring is home to dense H II regions, providing evidence of rapid star formation rates. Ionised hydrogen emission does not follow an even pattern and the galaxy features faint spiral arms due to a barlens structure.
Capturing NGC 1291
An amateur telescope has captured NGC 1291 at its finest using RGB broadband filters to produce this composite optical image that showcases NGC 1291 to its best advantage. However, due to Milky Way interference and distant galaxies in the background, its true beauty may remain somewhat obscured by these elements.
