M45- The Pleiades Cluster

M45- The Pleiades Cluster

The Pleiades, also known as M45, the Seven Sisters or Subaru (Japan), is an open star cluster containing middle-aged stars located in the constellation of Taurus. It is among the nearest star clusters to Earth and is the cluster most obvious to the naked eye in the night sky.

The cluster is dominated by hot blue and extremely luminous stars that have formed within the last 100 million years. Dust that forms a faint reflection nebulosity around the brightest stars was thought at first to be left over from the formation of the cluster is now known to be an unrelated dust cloud in the interstellar medium, through which the stars are currently passing. Computer simulations have shown that the Pleiades was probably formed from a compact configuration that resembled the Orion Nebula. Astronomers estimate that the cluster will survive for about another 250 million years, after which it will disperse due to gravitational interactions with its galactic neighborhood.

Milky Way

Milky Way

The Milky Way is the galaxy that contains our Solar System. The Milky Way is a barred spiral galaxy some 100,000–120,000 light-years in diameter, which contains 100–400 billion stars. It may contain at least as many planets as well. The Solar System is located within the disk, about 27,000 light-years away from the Galactic Center, on the inner edge of one of the spiral-shaped concentrations of gas and dust called the Orion Arm. The stars in the inner ≈10,000 light-years form a bulge and one or more bars that radiate from the bulge. The very center is marked by an intense radio source named, Sagittarius A*, which is likely to be a supermassive black hole. Stars and gases at a wide range of distances from the Galactic center orbit at approximately 220 kilometers per second. The constant rotation speed contradicts the laws of Keplerian dynamics and suggests that much of the mass of the Milky Way does not emit or absorb electromagnetic radiation. This mass has been given the name “dark matter”. The rotational period is about 240 million years at the position of the Sun. The Galaxy as a whole is moving at a velocity of approximately 600 km per second with respect to extragalactic frames of reference. The oldest known star in the Galaxy is at least 13.6 billion years old and thus must have formed shortly after the Big Bang. Surrounded by several smaller satellite galaxies, the Milky Way is part of the Local Group of galaxies, which forms a subcomponent of the Virgo Supercluster.

Zodiacal Light

Zodiacal  Light

This panorama of 2016’s very first sighting of the Milky Way in the area was shot with a timeless beauty, a vintage Minolta lens, the MC Rokkor PG 58mm/f1.2 to be exact. I was skeptical about a vintage lens lacking all the modern lens coatings to perform the way it did. It is akin to using a 1968 slide ruler (Google it you, millennials!!) to perform a complex calculation that would require a computer now.

That is not what is special about this picture. What is special is the fact that I captured the more timeless beauty, the Zodiacal Light that is so coveted by astrophotographers.

Thanks to Wisanu Boonrawd for identifying it. Zodiacal light is a faint, roughly triangular, diffuse white glow seen in the night sky that appears to extend up from the vicinity of the Sun along the ecliptic or zodiac. In this picture you see the Zodiacal light right at the bottom center of the horizon. Zodiacal light is produced by sunlight reflecting off dust particles in the Solar System known as cosmic dust.

Pleiades, 50mm, No Tracking, Finger Lakes region of New York

Now that the Milky Way is settling down for the winter, I decided to move on to other subjects on this very clear night. My last few outings have been increasingly plagued by dew forming on my lens. Actually, my entire camera has been dripping wet most nights. So I went to Walmart yesterday and grabbed a few sets of hand-warmers and taped a pair around my lens. They fit perfectly! No need to wipe every 90 seconds. I shot for hours without any dew at all, while my car made puddles around its perimeter.

Because my nifty-fifty gets nasty real quick on any stars that aren’t near dead-center, I had to re-frame the Pleiades every 5 minutes or less. That makes a pretty big difference. I also shot nearly 600 dew-free frames of Andromeda last night. Here’s that:

I used DeepSkyStacker to stack 238 images captured with my Canon 50mm f/1.8 set to f/2.2, 5-seconds, ISO 12800 on a Canon 60D body.

I stretched the output just a bit in Photoshop — only 1-1/2 Levels adjustments — any more brought all the noise back. I was pleased to get this much dust glow without having a background that looked like a rain-soaked end-of-semester sofa sitting at the curb. I tweaked the colors a bit to get some blue back, and then cropped and re-sampled the image 200 percent.

My computer, my drives and my long lens are conspiring to get a cheap tracker for me this Christmas. They’ve had just about enough of these shenanigans.

Pleiades

Pleiades

The Pleiades (M45). This is a shot I’ve been wanting to do for a long time. Previous attempts were unsatisfactory because my 127 Mak has too much focal length for this object and looked straight through it and using a camera lens made unattractive spokes around the stars caused by the iris of the lens. With the 150mm Newtonian scope the framing is pretty much perfect and plenty of nebulosity can be captured. Also the spikes caused by the secondary mirror spider add to the image. Not perfect perhaps but definitely the best attempt so far. This image has been edited sine originally being posted with extra data added and flat files replaced.
