Messier 45 (2021)

Constellation: Taurus

Messier 45, one of the more famous open clusters. Often called the Pleiades or the Seven Sisters, with the name Pleiades coming from Greek mythology. The cluster has been known since ancient times, and can be seen as a grouping of 6-7 stars, so it was interesting that Charles Messier included it in his catalog of objects that are not a comet, but could be mistaken for one.

The cluster is surrounded by a reflection nebula that the group is currently passing through, and not related to its original birth in a compact nebula. The cluster consist of at least 1,000 stars located in a radius of 8 light years. The cluster is dominated by hot blue luminous stars, but also contains many brown dwarfs that are not massive enough to initiate nuclear fusion. The estimated age of the cluster is around 100 million years, and its expected to take 250 million years to disperse due to gravitational interactions.

NGC 457 - Owl Cluster (2021)

Right Ascension: 01h 19m 32.6s
Declination: +58° 17′ 27″
Distance: 7,900

NGC 457 is an open cluster located in Cassiopeia, often called the Owl cluster, or a more recently the E.T. cluster with the two brightest stars forming eyes. I tend to see it more as an Owl. The cluster contains some 150 members and has an estimated age of around 21 million years. Less than idea weather for imaging, with a thin cirrus clouds, but a good bright target for commissioning the RC 10 scope and the ZWO 2600 mono camera.

NGC 157 is a spiral galaxy with somewhat distorted arms located in the constellation of Cetus. Discovered by William Herschel in 1783. Many other distant galaxies are visible in this area notated by PGC numbers.

Messier 2 is a globular cluster located in Aquarius. Containing around 150,000 stars. it is also one of the older and largest of the Milky Way globular clusters. Esimated age is 13 billion years and spans 175 light years in diameter.

Was using it as a test object for my new to me camera.

NGC 2261 Hubble's Variable Nebula (2021)

Constellation: Monoceros
Right Ascension: 6h 39m 10s
Declination: +8° 45′
Distance: 2,500 ly
Star InactiveStar InactiveStar InactiveStar InactiveStar Inactive

So named because of its changing light and dark patterns on the nebula is though to be caused by dust clouds near the illuminating source by the star R Monocerotis casting shadows on the nebula. The star itself a T Tauri variable, is encased dense clouds of dust.

The patterns are know to change over weeks and months. Discovered by William Herschel and studied by Edin Hubble.

Emission nebula NGC 1491, sometimes called the Fossil Footprint Nebula located in Perseus. Located about 10,700 light years away. Illuminated by a 11.2 magnitude star actually blowing a bubble in the nebula from its intense stellar "wind".
