NGC 7129 is an open star cluster located in the constellation Cepheus. This cluster is associated with a reflection nebula, meaning it shines due to the scattered light from nearby stars rather than emitting its own light. NGC 7129 is situated approximately 3,300 light-years away from Earth.

M94 is classified as having a low ionization nuclear emission region (LINER) nucleus. LINERs in general are characterized by optical spectra that reveal that ionized gas is present but the gas is only weakly ionized (i.e. the atoms are missing relatively few electrons). M94 contains both an inner ring with a diameter of 70 arcseconds (approximately 5400 LY, 1.700 kpc at the distance of M94) and an outer ring with a diameter of 600 arcseconds (approx. 45,000 LY, 14 kpc). These rings appear to form at resonance locations within the disk of the galaxy. The inner ring is the site of strong star formation activity and is sometimes referred to as a starburst ring. This star formation is fueled by gas that is dynamically driven into the ring by the inner oval-shaped bar-like structure.

NGC 2419 is a globular cluster located in the constellation Lynx, being about 300,000 light-years from the solar system, it is also called the intergalactic wanderer, because in the past it was not considered as an object in orbit around our galaxy.
