astroenthusiast 279 Posted March 22, 2021 The galaxy NGC 3938, lies at 30.7 megaparsec away, putting it at around 65 million light years from our planet. In 2017 a blue supergiant star, located in NGC 3938 went supernova and exploded with the mass of 50 suns in what Astronomers call the force of a Type 1C category supernova explosion! The amateur-astronomical equipment used, Explorer Scientific F/7, 165mm Triplet APO refractor, a 0.75x focal reducer and ASI2600 CMOS color camera. All stars and galaxies were processed out. 1 Link to comment
skybadger 538 Posted March 23, 2021 30.7MP equates to 95 M ly since a parsec is 3.2 ly. IIRC. 1 Link to comment

astroenthusiast 279 Posted March 28, 2021 Found a space ly to mpc converter, puts it at around 19.292 mpc away. Link to comment
