to capture data for the barred spiral galaxy NGC1300 to see if we could detect the aftermath of the supernova that  occurred in this galaxy in 2022. We could not find any bright stars where they shouldn't be so we concluded that the supernova has faded to a magnitude below the depth of the exposure. We have however included a HST image of this spectacular galaxy which highlights its

"Bold and beautiful, NGC 1300 is a marvellous example of a barred spiral galaxy. Unlike in other spiral galaxies where the starry arms curl outward from the centre of the galaxy, NGC 1300's arms twist away from the ends of a straight bar of stars that stretches across the galaxy's core. Observational evidence suggests that our own galaxy, the Milky Way, is a barred spiral as well.


NGC 1300's spiral arms include blue clusters of young stars, pink clouds that are forming new stars, and dark lanes of dust. Two prominent dust lanes also cut through the galaxy's bar, which contains mostly older, orangish stars. These dust lanes disappear into a tight spiral feature at the centre of the bar. Interestingly, only galaxies with large bars appear to have such a "spiral within a spiral." Hubble's image of NGC 1300, taken with the Advanced Camera for Surveys, reveals finer details in these features than ever seen before". NASA
