NGC 7479 (2022)
- Constellation: Pegasus
- Right Ascension: 23h 04m 56.6s
- Declination: +12° 19′ 22″
- Distance: 105 million ly
- Galaxy Type: SB(s)c
NGC 7479 is a barred spiral galaxy located in Pegasus. A prominent bar along with some what asymmetrical arms are visible. The asymmetry is probably due to a recent merger as the galaxy is still undergoing star burst activity throughout the galaxy.

Messier 8 - Lagoon Nebula (2022)
- Constellation: Sagittarius
- Right Ascension: 18h 03m 37s
- Declination: −24° 23′ 12″
- Distance: 4,100 ly
Messier 8 is a large emission nebula located in Sagittarius. Intense ultraviolet radiation emitted from hot young stars in the nebula cause the atomic hydrogen to glow a pinkish red. A star forming region, the nebula contains the open cluster NGC 6530 along with several Bok globules, which are dark collapsing areas of the nebula, along with 4 Herbig-Haro objects which are patches of nebulosity associated with newly born stars. The entire nebula spans a radius of 55 ly x 20 ly. It is one of only two nebula in the northern hemisphere barely visible as a patch of nebulosity. The other being the Orion Nebula.

NGC 4647 and Messier 60, Dance of Galaxies.
- Constellation: Virgo
- Right Ascension: 12h 43m 32.3s
- Declination: 11° 34′ 55″
- Distance: 56 million ly - 63 million ly
NGC 4647 is an intermediate spiral galaxy, and Messier 60 is elliptical galaxy that are just beginning to interact with each other. The pair of interacting galaxies are cataloged as Arp 116, which is a catalog of interacting galaxies. The pair are a part of the Virgo galaxy cluster.

NGC 5897 (2022)
- Constellation: Libra
- Right Ascension: 15h 17m 24.40s
- Declination: −21° 00′ 36.4″
- Distance: 40,000 ly
NGC 5897 is a globular cluster that is a satellite globular of the Milky Way Galaxy. Forming at or before the formation of our galaxy, they typically range in age of 10-12 billion years old. Age is estimated based on the amount of metal located in the stars, which is considered to be anything other than hydrogen and helium. It's measure of metallicity is measured at -1.9 (Fe/H). NGC 5897 has a low density of stars, and using the Sawyer Concentration class which ranges from 1 to 12 (most to least), it is ranked as a low 11.

Draco Dwarf Galaxy
- Constellation: Draco
- Right Ascension: 17h 20m 12.4
- Declination: +57° 54′ 55″
- Distance: 260,000 ly
A bit difficult to see, it was only noticed in 1954 from Palomar sky survey photographic plates. It is a satellite galaxy of our Milky Way galaxy.
Consisting of mostly old population stars its virtually dust free thus not creating very many new stars.

Baade's Window (2022)
- Constellation: Sagittarius
- Right Ascension: 18h 03m 32.14s
- Declination: -30d 02m 06.96s
Baade's Window is the largest of 6 relative dust free zones allowing astronomers to study stars in the central bulge of the Milky Way Galaxy. Nothing illustrates the billions of stars in our galaxy like a view of the view of the galactic center, even if only a tiny slice.
Also visible are two globular clusters, NGC 6522 at the center and NGC 6528 below. NGC 6522 is centered in the view of Baade's Window, and at an estimated age of 12 billion years makes it one of the oldest around our galaxy and lies at a distance of 25,100 light years. NGC 6528 is 25,800 light years distant and is unusually meta rich for a globular
The bright star in the lower left is W Sgr, which is a multiple star system, and the primary star is a classical Cepheid variable star that it's magnitude varies over 7 1/2 days.
