Astrophotography of the Year 2025
LTNF 1, PNG 144.8+65.8 is an old very faint planetary nebula in the constellation Ursa Major, here elaborated in H(L)OO narrowband
LTNF 1, PNG 144.8+65.8 is an old very faint planetary nebula in the constellation Ursa Major with very low surface brightness and a diameter of about 6 arc minutes.
The central star of this planetary nebula is a cataclysmic variable star known as BE UMa. It is a highly excited nebula with an eclipsing binary star system (BE Ursae Majoris) at its center, which has given rise to its unusual morphology. It is about 5,000 light-years from Earth and is so transparent that galaxies can be seen through it.
It was discovered in 1995 by James Liebert, Richard Tweedy, Ralf Napiwotzki and Michael Fulbright.
At that time it was a joint project with Sven Eklund.

LTNF 1, PNG 144.8+65.8 is an old very faint planetary nebula in the constellation Ursa Major, here elaborated in LRGB without narrowband data
LTNF 1, PNG 144.8+65.8 is an old very faint planetary nebula in the constellation Ursa Major with very low surface brightness and a diameter of about 6 arc minutes. In the LRGB elaboration, the LTNF 1 only guess.
An incredible number of small galaxies are located in the LRGB shot with only 1 hour 47 minutes exposure.
The central star of this planetary nebula is a cataclysmic variable star known as BE UMa. It is a highly excited nebula with an eclipsing binary star system (BE Ursae Majoris) at its center, which has given rise to its unusual morphology.

Messier 97 and Messier 108 in the constellation Ursa Major (Ursa Major), here in LRGB+Ha
Messier 97 and Messier 108 in the constellation Ursa Major (Ursa Major), is home to many galaxies worth seeing.
Messier 97 (NGC 3587), known as the "Owl Nebula," is a planetary nebula in our Milky Way galaxy, 2,600 light-years away. It has an apparent diameter of about 3.5′ and an apparent magnitude of 9.9. The actual diameter of the ejected gas envelope is about 2 light-years, and it is expanding at about 40 km/s.
Messier 108 (NGC 3556), known as the "Surfboard Galaxy," is an extragalactic object, a Hubble-type Sc spiral galaxy located 34 million light-years away. It appears to us with angular dimensions of 8.7' × 2.2' and an apparent magnitude of 9.9. We see the galaxy almost edge-on, comparable to Messier 82.
M97 and M108 were discovered in 1781 by the French astronomer Pierre Méchain.

NGC 5363 and NGC 5364 = NGC 5317. The NGC 5364 group, also LGG 362 with Abell 1809, is located in the constellation Virgo in the northern sky.
NGC 5363 and NGC 5364 = NGC 5317. The NGC 5364 group, also LGG 362 with Abell 1809, is located in the constellation Virgo in the northern sky.
It is about 54 million light-years away from the Milky Way and has a diameter of about 105,000 light-years.
The object has a companion galaxy, NGC 5363, whose gravitational forces are responsible for the extensive star-forming regions in the spiral arms.
The galaxy was discovered on February 2, 1786 by William Herschel (listed as NGC 5364).
“Rediscovered” on April 7, 1828 by John Herschel and listed as NGC 5317.

The Whirlpool Galaxy, Messier 51 or NGC 5194/5195, is called, is a large spiral galaxy in the constellation Canes Venatici.
The Whirlpool Galaxy, Messier 51 or NGC 5194/5195, is called, is a large spiral galaxy in the constellation Canes Venatici.
It is a Hubble-type Sc star, meaning it has a distinct spiral structure. According to current measurements, its distance from our Milky Way is 24.3 ±0.8 million light-years. M 51 has a nearby, interacting companion, listed in the New General Catalogue as NGC 5195; M 51 itself has the number NGC 5194.
M 51 is currently experiencing exceptionally active star formation, likely caused by tidal interaction with NGC 5195. Therefore, the galaxy has a high proportion of young and massive stars, but these will have relatively short lives, a few million years. Three supernovae have been observed in M 51 within 17 years, and a supermassive black hole is located at its center.
The galaxy was discovered on October 13, 1773 by the French astronomer Charles Messier discovered and added to his catalogue of diffuse objects with the number 51.
In 1845, the Irish astronomer William Parsons (Lord Rosse) with his giant telescope Leviathan was the first to observe the spiral structure of the object.

Messier 102, also known as NGC 5866, is a lenticular galaxy in the constellation Draco.
Messier 102, also known as NGC 5866, is a lenticular galaxy with dimensions of 6.5′ × 3.1′ and an apparent magnitude of 9.9 in the constellation Draco.
Because it is considered the prototype of a lenticular galaxy, i.e., a Hubble-type S0 galaxy, it is also known as the "Spindle Galaxy." However, this name is ambiguous, as, for example, the also lenticular galaxy NGC 3115 is also referred to by the same name.
Diameter: 60,000 ly, distance: 44 million light years, surface brightness: 13.0 mag/arcmin².

The Ursa Minor dwarf galaxy UGC 9749
The Ursa Minor dwarf galaxy UGC 9749 is an elliptical dwarf galaxy approximately 225,000 light-years away in the constellation Ursa Minor.
Its diameter is about 2,000 light years.
It was founded in 1954 by Albert George Wilson discovered at the Lowell Observatory and is a satellite of the Milky Way.
217 / 5.000
Although unspectacular, UMi Dwarf is difficult to image and therefore rarely photographed. The galaxy consists primarily of an older star population and shows little to no recent star formation.
In 1999, the Astrophysiker Kenneth Mighell und Christopher Burke Using the Hubble Space Telescope, scientists were able to show that the Ursa Minor dwarf galaxy experienced only a single phase of star formation until about 11 billion years ago, which lasted for about 2 billion years.
