alan4908 Posted May 29, 2022 Share Posted May 29, 2022 A somewhat neglected image target, NGC 3359 is a barred spiral galaxy about 50 million light years distant located in Ursa Major. The central bar is relatively young at an estimated 0.5 billion years. The galaxy is very colourful with the bluish spiral arms incorporating young energetic blue stars and vast regions of intense star formation which appear as pinkish glows. The LRGB image below was taken with my Esprit 150 and represents an integration time of about 16 hours. Alan LIGHTS: L:39, R:17, G:20, B:18 x 600s all at -20C. 9 Link to comment Share on other sites More sharing options...
