M106
M 106 (also known as NGC 4258) is a spiral galaxy visible in the constellation of Hunting Dogs; it appears to contain a supermassive black hole inside.
M106 is an example of a Seyfert galaxy; the detection of unusual radio wave and X-ray emissions observed through the Very Large Baseline Array radio telescope indicates that probably part of the galaxy is precipitating into a supermassive black hole located in its center: in fact it seems that a mass equal to 36 million is contained in the core of solar masses, concentrated in a volume between 1/24 and 1/12 of a light year, or between 12,000 to 54,000 AU.
The shape of M106 resembles that of the Andromeda Galaxy (M31), but with a different inclination, so that all the structures of the dust clouds on the galactic plane are perfectly visible; the spiral arms are rich in H II regions which in the images are shown in blue and red color, depending on whether or not they are associated with clusters of particularly hot and bright stars. In 1981 a supernova appeared between its arms, classified as SN 1981K, which reached the sixteenth apparent magnitude; since the spectrum was not analyzed, it was never known what kind of supernova it was. The distance of the galaxy is estimated at 21-25 million light years and its total mass is approximately 190 billion solar masses; it moves away from us at the speed of 537 km / s.

Dolphin Head Nebula by Wael Omar, on Flickr
Hello,
My image for "Dolphin Head " Nebula.
This is the hardest target i 've ever imaged since i start this hobby . Its a very faint nebula just above the horizon by 36 degrees and few hours to capture every night plus its very small in size relative to my gears FOV. ( I use Redcat 51).
I traveled around 1000 km through EGYPT to capture this Nebula in Bortle 9 , 4 ,2 regions to catch enough Data for it.
Dolphin Head nebula is HII region in Canis major constellation. The nebula is the Blue Bubble around the yellow star of a type " Wolf Rayet " and called EZ Canis major , This wolf rayet star have completely lost their outer hydrogen and are fusing helium or heavier elements in the core. Their spectra showing prominent broad emission lines of ionised helium and highly ionised nitrogen or carbon and so have very high surface temp around 89000 Kelvin.This star is in the brief, pre-supernova phase of its stellar evolution.
The Nebula is about 4900 Light years from earth ,its HII region blown by stellar winds up to 1,700 km/s and ionized by the intense UV radiation.
I pushed my gears so hard to get most of the nebula and reach 1200 seconds of exposure / frame. I stack most of the frames but remove some taken in bortle 9 because the LP gradients were so heavy that wash out details of the cleaner frames in Bortle 2 after stacking.

Good afternoon,

I would like to share my latest work, this time on the Orion constellation with LDN 1622 and the Barnard's Loop. Thanks for your time.

Full HD: https://www.astrobin.com/full/mhl0qd/0/

The Lynd's Dark Nebula 1622, also known as Boogeyman Nebula, can be found in the Orion constellation very close to other well known nebulae such as the M78 nebula or the popular Great Orion Nebula (M42). The LDN 1622 shows an intricate silhouette mostly composed of dark nebulae. Complex structures of dust that can be detected through the use of long exposures with broad band filters.

Surrounding this dark nebulae we see the prominent structure of the Barnard's Loop Nebulae. This emission nebula is composed of huge HII regions that can be easily detected by the use of narrow band Ha filters.

Very very interesting, Osama!

Note that the supernova appears to be very bright compared with the parent galaxy. It is also bluish in color, so we may guess that it is a supernova type Ia. That is indeed the case, too.

Again, very interesting! Thank you!

Ngc3628 Hamburger

NGC 3628, also known as the Hamburger Galaxy or Sarah's Galaxy, is an unbarred spiral galaxy about 35 million light-years away in the constellation Leo. It was discovered by William Herschel in 1784. It has an approximately 300,000 light-years long tidal tail. Along with M65 and M66, NGC 3628 forms the Leo Triplet, a small group of galaxies. Its most conspicuous feature is the broad and obscuring band of dust located along the outer edge of its spiral arms, effectively transecting the galaxy to the view from Earth.

Due to the presence of an x-shaped bulge, visible in multiple wavelengths, it has been argued that NGC 3628 is instead a barred spiral galaxy with the bar seen end-on. Simulations have shown that bars often form in disk galaxies during interactions and mergers, and NGC 3628 is known to be interacting with its two large neighbors.

Horizons and roads

Copyright: Rafael Schmall


Only the center of our galaxy in the southeast starts to appear from Hungary at spring dawn. As the days go by, the period of total darkness becomes shorter and shorter, so there is less and less time to detect the Milky Way at first until the summer solstice.

My big favorite is the sight of spring rapeseed fields, but photographing the starry sky with a rapeseed foreground isn’t that easy because of the silly weather.

I took panoramas and all sorts of pictures this dawn, but still, this Milky Way, which swam from the left, caught the road the best. Simple picture but very cozy for me.

Southern Cross

One of the most iconic constellation of the southern hemisphere. It lies on the southern end of the Milky Way. The name Crux is Latin for cross. Even though it is the smallest of all 88 modern constellations, Crux is among the most easily distinguished as its four main stars each have an apparent visual magnitude brighter than +2.8. It has attained a high level of cultural significance in many Southern Hemisphere states and nations.

Wizard Nebula


Wizard Stars (rotated) by mark h, on Flickr

From Wikipedia:
"NGC 7380 is a young open cluster of stars in the northern circumpolar constellation of Cepheus, discovered by Caroline Herschel in 1787. The NGC 7380 complex is located at a distance of approximately 8.5 kilolight-years from the Sun, in the Perseus Arm of the Milky Way. The cluster spans ~20 light-years with an elongated shape and an extended tail. Age estimates range from 4 to 11.9 million years. At the center of the cluster lies DH Cephei, a close, double-lined spectroscopic binary system consisting of two massive O-type stars. This pair are the primary ionizing source for the surrounding H II region, and are driving out the surrounding gas and dust while triggering star formation in the neighboring region."

Messier 68

Situated opposite to the Galactic Center which is an unusual place for a globular, Messier 68 is orbiting the galactic bulge with an eccentricity of 0,5. Lying at a distance of about 33,000 light years from earth, the cluster spreads over 106 light years in diameter.
Messier 68 is quite difficult to observe for Northern Hemisphere because of its southern declination. Though it can be found by following a line from the stars Delta to Beta Corvi (mag 3), which points toward 5.4-mag ADS 8612 (SAO 180965). M68 is then easily located about 45 minutes NE of this star.

planet alignment by Wael Omar, on Flickr

Planets orbit around the sun in our solar system in elliptic path with different speeds and distance from the sun. Due to this difference there are times where the planets appeared visually from earth in aligned configuration. These days ,Four shiny planets are lined up over the eastern horizon before dawn (Saturn - Mars- Jupiter-Venus) , i started last week to plan an imaging session for them .
Two days ago i managed to take the shot away from the city by about 25 km ,i climbed a mountain of height 550 meters . I setup my gears ( Canon 5D mark IV) with canon 70-200 mm lens on a fixed tripod . My plan was to shoot the iconic towers and buildings in the new constructed city in the eastern desert of EGYPT called " New capital" in a panoramic rows with different settings to stack them into HDR image and make a blending with the sky when the 4 planets come over the horizon.
Foreground : 21 images at different settings for HDR.
Sky: 61 images with sigma 35 mm at F8 , iso 6400 , 8 seconds.
Location : New capital, Egypt.
The diffraction spikes around the planets are formed by making the aperture of the lens at F8, i intend to do so to make this beautiful spikes around Venus and Jupiter.
The 4 planets are in a very wide field in the sky so i succeeded in put only 3 of them into my FOV ( Mars - Jupiter - Venus).
