Photo description / processing

Very little integration time (clouds rolled in) and an almost full moon. I didn't want to publish this, the quality is low, there's almost no data, but it's a very interesting object, or rather two. NGC 247 is 11.8 million light-years away from us, with a diameter of about 70 thousand light-years. The galaxy's angular size is 19.2x5.5 arcminutes. NGC 247 has a void that is clearly visible in photographs, which is why it is called the "Needle's Eye" galaxy. It is located in the constellation Cetus. It is difficult to observe at mid-latitudes in Russia. Nearby is a group of 4 galaxies called the "Burbidge Chain." This group of galaxies is about 350 million light-years away from us, which is almost 30 times farther than NGC 247. I hope to return to this most interesting object and take a quality photo.
