Mosaic of 6 images stitched together covering the Large Magellenic Cloud. 10 000 million stars about 180000 light years away form this barred dwarf galaxy. Recent proper motion studies indicate that the LMC and SMC have just arrived after being ejected from the direction of M31.
If you look carefully enough at this image you will see the impact of thermal focus shifts, variation in seeing and guiding differences over the three nights these images were acquired.
It's bad enough that I will do this again next year, perhaps using a focal reducer to limit the number of frames.
