Large Perseus Cluster of galaxies. NGC 1272 is elliptical galaxy, and NGC 1275 - lenticular. Many other galaxies have accumulated around this pair. Very productive area for imaging.
These galaxies were discovered by the German astronomer Henry Louis D'Arré on February 14, 1863.

NGC 4565 (also known as the Needle Galaxy or Caldwell 38) is an edge-on spiral galaxy about 30 to 50 million light-years away in the constellation Coma Berenices. It lies close to the North Galactic Pole and has a visual magnitude of approximately 10. It is known as the Needle Galaxy for its narrow profile. First recorded in 1785 by William Herschel, it is a prominent example of an edge-on spiral galaxy.
L = 31 * 900 sec. bin1, R = 12 * 1000 sec. bin2, G = 12 * 1100 sec. bin2, B = 12 * 1200 sec. bin2.

NGC 2903 is a field barred spiral galaxy about 30 million light-years away in the constellation Leo. It was discovered by William Herschel who cataloged it on November 16, 1784. NGC 2903 has a very high speed of creating new stars in the central region.
L = 34 * 900 sec. bin1, R = 10 * 1000 sec. bin2, G = 10 * 1100 sec. bin2, B = 10 * 1200 sec. bin2, Ha = 12 * 1800 sec. bin2.

The Ghost Nebula (designated Sh2-136 and VdB 141) is a reflection nebula located in the constellation Cepheus. Looking at the adjacent image, the nebula's name is easily understood. The Ghost nebula is referred to as a globule (cataloged CB230) and over 2 light-years across. There are several stars embedded, whose emissions make the nebula shine in brownish color.
L = 17 * 1800 sec. bin1, RGB = 10 * 1000, 1150, 1300 sec. bin2, in each channel.
