Summer Triangle Challenge

M33 - Triangulum Galaxy


I'm pleased with this image given that the first subframe was smeared badly due to tracking errors caused by cloud. That cleared and stayed away until 5 minutes after the last frame that I took. I'm delighted with the detail that I captured, especially that of NGC604 (the red blob in the lower right).
M33 is a spiral galaxy approximately 3Mly from Earth and is part of our local group of galaxies. It is believed that it is a satellite galaxy of M31 (the Andromeda Galaxy) due to their gravitational interactions. NGC604 and NGC595 are large H II regions in the galaxy and are highly active. NGC604 is approximately 1500 light years across, over 40 times larger than the Orion Nebula and over 6300 times more luminous.
