Equinox crepuscular rays
equinox_crepuscular_rays_abraham.jpg
As I was playing football with my sons in the garden, I observed the crepuscular rays. Running up on the stair for the camera and running down to catch the view from the garden. The scene was beautiful with my almond tree and Cotynus coggygria bushes.

Blue Horsehead and Rho Ophiuchi Cloud Complex with Guest Planet
Credit: Amit Ashok Kamble

Had this little project in mind for a wee while, Had collected the data back in April when the Galactic core was rising and going over head. I took whole bunch of data over few weeks and ended up with 5 hours worth of data.
BUT, one thing I did not consider is the position of mars over few weeks (Center super bright object), I thought if I keep collecting data and stack them, I might be able to get rid of it, but because it was in a stack of few hundred images, I could not get rid of it and the stack look horrible with 5 bright red Mars across the image, so decided to ignore rest of the data and only stack from one session.
The image shows an interesting part of the night sky:
1) The blue horsehead nebula (IC4592) is a reflection nebula in the Scorpius constellation that is lit by Nu Scorpii.
2) Rho Ophiuchi cloud complex is a dark nebula of gas and dust around 460 Light years away. Temperatures of the clouds range from 13–22 K, and there is a total of about 3,000 times the mass of the Sun in material. Over half of the mass of the complex is concentrated around the L1688 cloud, and this is the most active star-forming region. The million-year-old star at the center of the disk has a temperature of 3,000 K and is emitting 0.4 times the luminosity of the Sun. (Source : Wiki)
This image is made up of 115 x 60 sec = 1.91 Hrs (The clouds rolled in so had to skip around 30 frames)
Exif for each frame: 60sec, ISO 1600, f3.2 at 135mm using Tamron 70-200 on Canon 6D, tracked using iOptron Skytracker
Image was processed in PixInsight and Photoshop CC

Interstellar matter and dust

Banquet of interstellar dust matter and looking at the internal threads of our galaxy somewhere between Centaur Sagittarius and the powerful Scorpio in the constellation Ophiuchus, where the secular horse galloping our imagination inside the stars.

The main disc of our galaxy has a diameter of 80,000 to 100,000 light-years, the perimeter 250 to 300 000 light years and a thickness of about 1,000 light years. It consists of 200 up to 400 billion stars. If we define a natural scale and assume that the Milky Way has a diameter of 130 km, the solar system would have a length of 2 mm. The Galactic Halo extends over a diameter of 250,000 and 400,000 light years. As reported extensively in the galaxy structure below, new research has shown that the disk extends much more than we thought until last.

Officially, since 2005, the Milky Way is now considered to be a large barred spiral galaxy SBbc type the Hubble sequence (small barred spiral helix) with a total mass of 600 to 3,000 billion solar masses (M☉) [5] [6], comprising from 200 to 400,000,000,000 stars.
The galactic disk has an estimated diameter of about 100,000 light years. The distance of the Sun from the center of the galaxy is estimated at 26,000 light years. The disc is protuberant in the center and symperikleietai from the so-called thick disk.

The Sun (and thus the Earth and the Solar System) is quite close to the inner ring of the Arm of Orion, local cloud, at 7,94 ± 0,42 kpc from the Galactic Center. The distance between the local arm and immediately nearest, the Perseus Arm, is of the order of 1 · 1019 m (6.500 light years). The Sun and by extension the solar system, located in what scientists call the Galactic Habitable Zone.

The direction of the Sun's path (apix or corymb), refers to the direction of the Sun as it travels in the Galaxy. The general direction of galactic motion of the Sun is near the constellation Hercules, at an angle of approximately 86 degrees from the Galactic Center. The orbit of the Sun in the Galaxy is expected to be approximately elliptical with the addition of influences from the galactic arms and uneven mass distribution. We are currently 1/8 of the track before perigalaxio (the shortest distance from the center of the Milky Way).

The solar system takes about 225-250000000 years to complete an orbit (one Galactic Year), so speculation has performed approximately 20-25 orbits during its lifetime. The orbital speed of the Solar System is 217 km / sec, ie. One light-year every 1,400 years, and 1 AU in 8 days.
