NGC 869 oraz NGC 884 – Double Cluster

Also known as Caldwell 14 or open clusters NGC 869 and NGC 884, ( often designated h Persei and χ Persei, respectively), which are close together in the constellation Perseus. Both visible with the naked eye, NGC 869 and NGC 884 lie at a distance of 7,500 light years.

There are more than 300 blue-white super-giant stars in each of the clusters. The clusters are also blueshifted, with NGC 869 approaching Earth at a speed of 39 km/s (24 mi/s) and NGC 884 approaching at a similar speed of 38 km/s (24 mi/s). Their hottest main sequence stars are of spectral type B0.

Double Cluster – also known as Caldwell 14 or open clusters NGC 869 and NGC 884

I remember the first time, I saw both clusters in the eyepiece of my old Newton 1000/200 [mm]. My eye stuck to the lens. I couldn’t take my eyes off it.

Unfortunately, I did not capture both clusters as I would like, the coma corrector was not well matched as seen on the edge of the frame. It will be better next time. I promise 😉

Albireo (Beta Cygni, β Cyg)

Is a double star designated Beta Cygni (β Cygni, abbreviated Beta Cyg, β Cyg). Beta Cygni is about 415 light-years (127 pc) away from the Sun. When viewed with the naked eye, Albireo appears to be a single star. However, in a telescope it resolves into a double star consisting of β Cygni A (amber, apparent magnitude 3.1), and β Cygni B (blue-green, apparent magnitude 5.1). Separated by 35 seconds of arc,[16] the two components provide one of the best contrasting double stars in the sky due to their different colors.

Albireo (Beta Cygni, β Cyg)

Somehow I have a weakness for this pair of stars. Whenever I look at them through the telescope eyepiece, I am fascinated with their colors and that they are so close together.

M33 / NGC 598 – Triangulum Galaxy

is a spiral galaxy 2.73 million light-years (ly) from Earth in the constellation Triangulum. It is catalogued as Messier 33 or NGC 598. The Triangulum Galaxy is the third-largest member of the Local Group of galaxies, behind the Milky Way and the Andromeda Galaxy. It is one of the most distant permanent objects that can be viewed with the naked eye. The galaxy gets its name from the constellation Triangulum, where it can be spotted.

Veil Nebula (NGC6960)

Is a cloud of heated and ionized gas and dust in the constellation Cygnus. It constitutes the visible portions of the Cygnus Loop a supernova remnant. The source supernova was a star 20 times more massive than the Sun, and it exploded around 21,000 years ago. The distance estimates of 2400 light-years is based on direct astrometric measurements.

The Hubble Space Telescope captured several images of the nebula. The analysis of the emissions from the nebula indicate the presence of oxygen, sulfur, and hydrogen. The Cygnus Loop is also a strong emitter of radio waves and x-rays.
