M102 is a small galaxy considered to be the same as NGC5866. It’s visually small even as galaxies go but it was in an easy part of the sky last night so i captured 30 subs of 60 seconds ISO 800 with the canon t3i and the william optics z61(360 f/6). The usual processing in Siril. The second picture below shows a broader crop where two other galaxies are obvious – NGC5879 on the lower left and NGC5905 on the right. M102 is about 50 million light years away. The third picture is a screencap of wikipedia’s image of M102 and the final one is wikipedia’s NGC5907 both of which blew me away.
