29 Orionis

This is a yellow giant Mag 4.14 star which is 174 Light Years Away. To the upper right is the bright star Tau Orionis Mag 3.60. To the bottom right one can just about see the brilliant glow of Rigel. To the top left one can just about see HR1840 and Thabit.
Using my 20x80 binoculars in the field of 29 Orionis and going from center south and then anticlockwise towards south west are
HD35261 Mag 7.58
HD35353 Mag 7.69
HR1778 Mag 5.90
HD35155 Mag 6.86
Travelling north west from there
HD34892 Mag 7.54

Although stable hydrogen gas is invisible optically, its presence is especially concentrated along the disk of our galaxy in its vast spiral arms. One such region is associated with the Orion Complex. So take some time to scan the sky due south of 3.4 magnitude Eta Orionis and note how few stars are visible between it and 4.2 magnitude 29 Orionis - some 5 and a half degrees away. Such regions are known to have high concentrations of 21 cm radiation caused by hydrogen gas that has yet to begin coalescing into new Suns such as our own.

Destination Kuiper Belt

For the first time in the history of mankind, a mission to explore the outer reaches of the solar system beginning with the Kuiper Belt Objects Pluto and Charon is being launched now as I write.
The mission to explore the Astrophysical and Astrochemical properties of these icy bodies. Expected time of arrival 2015. Good Luck and Fingers Crossed for the fastest spacecraft ever launched in the history of Space Exploration.

Thabit 36 Upsilon Orionis

HR1855, HD36512, SAO132222, BD-7 1106, NSV16333
Can be found beneath Orion's Sword in between 49 Orionis and 29 Orionis

Upsilon Orionis (υ Ori / υ Orionis) is a star in the constellation Orion. It also has the traditional name Thabit (Arabic for "the imperturbable one").

What is quite distinctive about Thabit Mag 4.62 is how it is surrounded by its nearby stars to give the appearance of a sort of tetragonal pyramid in the night sky, as viewed through my binoculars at Mag8

The vertex of the pyramid would be HR1848 Mag 6.22 and the 4 base vertex points would be represented by HD36920 Mag 6.7, HD36814 Mag 6.45, HD36151 Mag 6.68, HD36285 Mag 6.33 Clockwise respectively from the lower left.

Thabit belongs to the spectral class B0V and has apparent magnitude +4.62 . Thabit is approximately 1545 light years from Earth.

NGC 1981

I was doing some doing some observation around Orion's Sword when I challenged myself to how many stars I could pick out within the upper part of the Open Cluster OCL 525 namely NGC 1981 at 400pc(parsecs)

This can be found directly underneath Epsilon Orionis in Orion's Belt, and above Orionis 45 and Orionis 42 that fall within NGC 1975 and NGC 1973

If you look at the image

I could quite easily pick out from my 20x80 binoculars atleast half a dozen stars within this cluster including notably
HR1898 HD37040 at Magnitude 6.38 Spectral Type B2.51V
HR1891 HD37016 at Magnitude 6.24 Spectral Type B2.5V
HR1890 HD37017 at Magnitude 6.56 Spectral Type B1.5V

Still trying to find out the distance to these stars, which you can quite easily infer to be very hot Blue stars. Anyone got data on the stellar distances to NGC 1981?

Anyone Out There

From the depths of the West Midlands, out through the stratosphere into the solar orbital plane, beyond the heliopause into the interstellar medium way past the milky way, beyond the local group of galaxies out into the local virgo supercluster into the unknown void to infinitum. Is there anybody out there interested in astronomy and all things myterious and inspiring.

Happy new year or should I create an alien talk of 209 binary sequential digits that can be translated into a prime number grid 11by19
For example have a look at this great article

I hope to share some of my finds of the deep sky with all so welcome to my world!
