The spiral galaxy NGC 7814 (Caldwell 43, "Little Sombrero") in the constellation Pegasus. The galaxy is seen edge-on from Earth. NGC 7814 is about 40 million light-years from Earth, has a diameter of 60,000 light-years and was discovered by William Herschel in 1784 (source: Wikipedia).

Forty-eight 3-minute exposures (144 minutes total exposure) at ISO 800 taken on September 30 / October 1, 2019 were added for this shot with the DeepSkyStacker software and the final image processing was done in Photoshop.

Equipment: Canon EOS 450D Baader modified camera, TeleVue Paracorr Type II coma corrector, 16" f/4.5 "Ninja" dobsonian telescope riding on a dual-axis Tom Osypowski equatorial platform, Lacerta MGEN autoguider, Lacerta off axis system (field of view comparison: image of the moon with the same equipment).
