NGC3628, also known as the Hamburger Galaxy, is a unbarred galaxy Type SAb pec edge-on spiral 35 million light-years from Earth in constellation Leo. NGC3628’s apparent magnitude is 9.5 and was discovered by William Hershel in 1784. It has an approximately 300,000 light-years long tidal tail, not shown because of processing out stray light artifacts. Along with M65 and M66, these three galaxies forms the Leo Triplet.

Due to the presence of an x-shaped bulge, visible in multiple wavelengths, it has been argued that NGC3628 is instead a barred spiral galaxy with the bar seen end-on. Simulations have shown that bars often form in disk galaxies during interactions and mergers, and NGC3628 is known to be interacting with its two large neighbors.

The list below exhibits the number of subframes used with the exposure time for each filter. All the subframes were calibrated with Flats, Darks and Biases by PixInsight. Afterwards the subframes were combined and processed to the final image.
