NGC 1169 (UGC 2503) is an intermediate barred spiral galaxy in the constellation of Perseus. NGC 1169 has a reddish center, indicating the region is dominated by older stars. In contrast, the outer ring contains larger blue-white stars, a sign of recent star formation. The entire galaxy is rotating at approximately 265 km/s. NGC 1169 was discovered on December 11, 1786 by William Herschel. Measurements of its distance range from 20.9 Mpc - 49.7 Mpc with an average of 35.1 Mpc.

The Bubble Nebula (NGC 7635) is an HII region in the constellation Cassiopeia. Its iconic “bubble” shape was created from the stellar wind created by the intensely hot central star (SAO 20575). Also designated Sharpless 162, and Caldwell 11, this unmistakable emission nebula sits within a giant, glowing molecular cloud. The Bubble itself is about 10 light-years in diameter.

The Veil Nebula is a supernova remnant located 2,100 lightyears away in the Cygnus constellation that spans 110 lightyears across. A supernova remnant is the remains of a star that has ended its life in an explosion known as a supernova. In the case of the Veil Nebula, the star in question was 20 times the mass of the Sun and exploded about 8,000 years ago. A blast wave from the stellar explosion is hitting cooler, more dense interstellar gas and emitting light in the process. The Veil Nebula is part of the larger Cygnus Loop structure, and the delicate filaments and almost fragile-looking structure are what give the Veil Nebula its nickname. Because the Veil Nebula is so expansive, astrophotographers love to capture separate sections of the nebula, which have been allocated different names.

The Crescent Nebula, or NGC 6888 as it is formally known, is a distinctive emission nebula that stretches about 25 lightyears across and is located about 5,000 lightyears away from Earth in the Cygnus constellation. Discovered by William Herschel in 1792, the Crescent Nebula is produced by a type of star known as a Wolf-Rayet.

This is a 2x2 mosaic of Pelican Nebula. The Pelican Nebula is a star-forming region about 30 light years wide located 1,800 lightyears from Earth. It is also known as IC 5070 and IC 5067, and is found near bright star Deneb in the Cygnus constellation.

M17, also known as the Omega Nebula or Swan Nebula, is one of the largest star-forming regions in the Milky Way galaxy. The Omega Nebula was discovered in 1745 by the Swiss astronomer Jean-Philippe Loys de Chéseaux. It is located 5,500 light-years from Earth in the constellation Sagittarius. The nebula has an apparent magnitude of 6 and can be seen with a pair of binoculars. M17, which appears near M16 and M18 in the sky, is best viewed on clear nights in August.

This 3x3 mosaic of M31 is my largest project so far. The 9 panels total 6 hours of exposure, using my QHY533M and a luminance filter. 36 files where stacked using Pixinsight into the nine raw panels. The mosaic assembly was done using Pixinsight (image solver, mosaic by coordinates, and gradientmerge mosaic). Further processing was also done in Pixinsight and Photoshop.

Barnard 104 is a dark nebula in the constellation Scutum , just north of the star Beta Scuti. It is commonly called the Fishhook Nebula, the Checkmark Nebula, and the "L" Nebula. Dark nebulae – or absorption nebulae – are clouds of gas and dust in space dense enough to obscure and block light from background stars. These vast clouds are mostly composed of molecular hydrogen. Often, they are locations where material is coalescing to form new stars.
