M33 – The Triangulum Galaxy
Around 2.7 million light-years away, M33 is one of our nearest galactic neighbours. This spiral galaxy is alive with star-forming regions. This image is a combination of RGB data and Ha data,with the added Ha data bringing its glowing red hydrogen nebulae to life against the blue hues of young stars.
This image combines data from two telescopes at drastically different focal lengths. The RGB data was shot with the skywatcher 72ED@420mm while the Ha data was shot on my 6”RC@1375mm focal length.
Images where registered and aligned in Pixinsight and then channel combined to produce a HaRGB image which shows off the beautiful star forming regions in the galaxy.
