The M81 and M82 group
The M81 and M82 group extends over the constellations Ursa Major and Giraffe. The distance from our sun to the center of the galaxy cluster is approximately 12 million light years. The M81 group is a group of galaxies that is located in the immediate vicinity of the so-called “Local Group”. In addition to the Milky Way, the Andromeda Galaxy also belongs to the Local Group. The two most famous galaxies in the group, M81 and M82, were discovered on December 31, 1774 by the German astronomer Johann Elert Bode.

NGC 6960 the Cirrus Nebula is part of the Cirrus Nebula complex
NGC 6960, the Cirrus Nebula, is part of the Cirrus Nebula complex – a supernova remnant in the constellation Cygnus that formed approximately 8,000 years ago. Due to its appearance, this beautiful emission and reflection nebula is generally considered to be „Sturmvogel“ known.
The bright star in the center is 52 Cyg (4.2 mag). NGC 6969 was discovered on September 7, 1784 by William Herschel.

NGC 7023 is a small open star cluster
NGC 7023 is a small, open star cluster, which is enveloped by a faint dust nebula (LBN 487).
It was discovered on October 18, 1794 by the German-British astronomer Wilhelm Herschel.
Dreyer described NGC 7023 as a 7th magnitude star embedded in a very faint but large nebula.
Due to their color and shape, the nickname “iris mist” refers to the blue flowers of the iris (Iris versicolor) and not the iris of the eye. Distance about 1300 light years. The star HD 200775 is a hot, blue Herbig Be star with an apparent brightness of about 7.4 magnitude. It emits most of its radiation in the UV range.
The mass is estimated to be around 10 to 15 times that of the Sun and the age to be 100,000 years.

The giant “squid nebula” is cataloged as Ou4 and, along with Sh2-129, is also known as the flying bat and giant squid nebula.
The giant “Squid Nebula” is cataloged as Ou4 and, along with Sh2-129, is also known as the Flying Bat Nebula, or “the flying bat and giant squid nebula.” The field is 3 degrees or 6 full moons wide.
The Squid Nebula was discovered in 2011 by French astrophotographer Nicolas Outters.
We can recognize its charming bipolar form here by the special blue-green emissions of doubly ionized oxygen atoms.
The Squid Nebula appears to be completely surrounded by the reddish hydrogen emission region Sh2-129, although its actual distance and nature have been difficult to determine. But a recent study shows that Ou4 is about 2,300 light-years away and really lies inside Sh2-129. Accordingly, Ou4 would be a spectacular outflow from HR8119, a triple system of hot massive stars that we see in the center of the nebula.
The truly massive Squid Nebula is physically nearly 50 light-years across.

Abell 85 also known as CTB 1 is a large supernova remnant
Abell 85, also known as CTB 1, is a large supernova remnant, which is located in the constellation Cassiopeia.
The southern part of the supernova bubble also made it into the Lynds Bright Nebula Catalog as LBN 576. Originally cataloged as a planetary nebula by George Abell, it quickly became clear that it was a supernova remnant. Abell 85 was also recognized as a radio source and was given the alternative designation CTB 1. On the left side of the field are a small reflection nebula (GN 23.50.6.03), clearly visible in this image, and a small possible planetary nebula (We 2-262). Abell 85 has relatively weak OIII and H-beta emissions compared to the traditional supernova remnant spectra of H-alpha, NII and SII.
In fact, this object is therefore often considered one of the most difficult objects to visually observe and continues to represent a major challenge for astrophotography.

Sh2-157 or Lobster Claw Nebula is a large emission nebula area in the constellation Cassiopeia
Sh2-157, or Lobster Claw Nebula, is a large emission nebula region in the constellation Cassiopeia which, in addition to Ha, OIII, also shows clear structures in SII. In the lower central area of the image, the Herbig-Haro object HH170 can be seen next to a brighter star.
This is gas ejected from a star that hits interstellar dust.
At the bottom right of the image you can see the glowing outcrops of the nebula around NGC7635. A bright compact open star cluster NGC7510 can be seen on the left edge of Sh2-157, at around 8 o'clock - its elongated shape is striking.
At the very left edge of the image you can find the small emission nebula IC1470.

The small planetary nebula PN LDu 14, PN G137.7+03.3
Elaboration from April 26, 2023
Sharpless Sh2-200 or PNG 138.1+04.1 or also known as HDW 2 (Hartl-Dengl-Weinberger 2), is a fairly old planetary nebula (PN) in the constellation Cassiopeia. In English the nebula is also called “Bearclaw nebula” – in German “Bear Paw Nebula”. The bright part of the object is about 6′ in diameter, north is at the top. It is a little-studied object that was initially cataloged as the H-II region. It was only recognized as a planetary nebula in 1983, in a study of some nebulae of unusual appearance.
Its distance is estimated at approximately 3590 light years. According to W.A. Weidmann and R. Gamen, who studied the central stars of various PNs, the central star of HDW 2 is a binary star.
The color of the object is a mix of the blue/green OIII and red/magenta Ha. The planetary nebula is almost spherical with pronounced streaks and a darker area to the south, surrounded by a thin gap. What appears to be an outer bright H-alpha ring or halo is probably the edge of an extensive spherical shell from another previous explosive event. This faint halo extends to a small open star cluster, Trumpler 3.
In my photo you can see the faint little round one at the bottom right Planetary nebula PN LDu 14, PN G137.7+03.3 recognize.
