Description

The Large Magellanic Cloud (LMC) is a satellite galaxy of the Milky Way. At a distance of 50 kiloparsecs (≈163,000 light-years), the LMC is the third-closest galaxy to the Milky Way, after the Sagittarius Dwarf Spheroidal (~ 16 kpc) and the putative Canis Major Dwarf Galaxy (~ 12.9 kpc, though its status as a galaxy is under dispute), lying close to the Galactic Center. The LMC has a diameter of about 14,000 light-years (4.3 kpc) based on readily visible stars and a mass of approximately 10 billion solar masses, making it roughly 1/100 as massive as the Milky Way.[3] Based on this, the LMC is the fourth-largest galaxy in the Local Group, after the Andromeda Galaxy (M31), the Milky Way, and the Triangulum Galaxy (M33). However, an emerging case for the LMC and the SMC being gravitationally bound, along with much of the material in the Magellanic Bridge plus Stream, traveling at a velocity too high to be in orbit with the Milky Way, suggests a total mass of up to 25% of the Milky Way.

The LMC is classified as a Magellanic spiral. It contains a stellar bar that is geometrically off-center, suggesting that it was a barred dwarf spiral galaxy before its spiral arms were disrupted, likely by tidal interactions from the Small Magellanic Cloud (SMC), and the Milky Way's gravity] The LMC's present irregular appearance is likely the result of repeated tidal interactions with the SMC primarily, as well as the Milky Way's tidal field.

With a declination of about −70°, the LMC is visible as a faint "cloud" only in the Southern Celestial Hemisphere and from latitudes south of 20° N, straddling the border between the constellations of Dorado and Mensa, and appears longer than 20 times the Moon's diameter (about 10° across) from dark sites away from light pollution.

I have a short period to use Southern Hemisphere scope so give this a try with idea perhaps make a mosaic as I have never tried such.
