NGC 2903
NGC 2903 is among the brightest galaxies in the northern sky, and it is only a coincidence that Charles Messier missed it when compiling his catalog. It was only discovered by William Herschel in 1784.
Although the total number of images is quite high, the shooting mostly took place under occasional high cloud cover and the resulting image corresponds to this. The processing was not easy either, but the result is usable.
