NGC 2237 Rosette Nebula

 

Distance from earth: appr. 5000 light years.

Diameter: 130-150 light years.

 

The radiation from the young stars excites the atoms in the nebula, causing them to emit radiation which is the emission nebula we see. The total mass of the complex is around 10000 solar masses.

IC 434, the "HorseHead" Nebula is an emission nebula in the constellation Orion and is 3.5 light years away. I setup my TS Optics 90mm CF APO f6 refractor with a Optolong L-Xtreme filter and shot this in a full moon! The filter did a great job cutting the moon light and I was able to get this beautiful narrowband image.

This large star forming region is called the Soul Nebula (or Embryo Nebula) and is found in the constellation Cassiopeia. This nebula is often shown next to the Heart Nebula (IC 1805). The Soul Nebula is about 6,500 light years away from Earth. The nebula contains several open clusters and there are few smaller emission nebulas around the perimeter. The star clusters are surrounded by hydrogen, which glows red from the young hot stars nearby.

My favourite target for testing telescopes, the North America Nebula, NGC 7000, in Cygnus, with its companion Pelican Nebula to the right, aka IC 5070. The bright star Deneb is at upper right. An odd little red nebula is to the right of the Pelican, of unknown identity as it is not in Deep Sky Atlas, Millenium Star Atlas, TriAtlas or SkySafari.

 

This is a stack of 15 x 6-minute exposures with the Astronomics Astro-Tech 90CFT apo refractor and its 0.8x Reducer/Flattener for f/4.8, as part of testing, and with the AstroGear modified Canon R camera at ISO 800. On the AP Mach 1 mount and auto-guided with the Lacerta MGENIII stand-alone guider. No filter was employed here, other than the Optolong IR Cut filter installed in the camera itself by AstroGear, replacing the Canon sensor filter.

 

Stacked, aligned and processed in Photoshop. with Lumenzia luminosity masks applied to a starless layer created with RC-Astro Star XTerminator to bring out the nebulosity independently from the rich starfield. Plus layers with PhotoKemi Nebula action and ON1 Effects Dynamic Contrast filter applied to further enhance the nebulosity and contrast.

 

Taken from home on a very fine warm and dry night, May 12/13, 2023, though with few hours of darkness at my latitude of 51° N in mid-May.

Here is the link to APOD - Astronomy Picture Of the Day (NASA): apod.nasa.gov/apod/ap171129.html

The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus.

 

It constitutes the visible portions of the Cygnus Loop, a supernova remnant, many portions of which have acquired their own individual names and catalogue identifiers. The source supernova was a star 20 times more massive than the Sun which exploded between 10,000 and 20,000 years ago. At the time of the explosion, the supernova would have appeared brighter than Venus in the sky, and visible in the daytime. The remnants have since expanded to cover an area of the sky roughly 3 degrees in diameter (about 6 times the diameter, and 36 times the area, of the full Moon). While previous distance estimates have ranged from 1200 to 5800 light-years, a recent determination of 2400 light-years is based on direct astrometric measurements. (The distance estimates affect also the estimates of size and age.)

M81 and M82 are a pair of interacting galaxies found in the constellation of Ursa Major.

 

M81 was discovered by Johann Alert Bode in 1774. The galaxy is approximately 11.5 million light years from earth and is one of the brightest galaxies in the night sky.

 

M82 also discovered by Johann Alert Bode, is known for its elongated cigar shape seen from Earth and contains high levels of star formation giving its alternative name the Starburst Galaxy. M82 is approximately 12 million light years from Earth.

 

This wide field image also includes NGC 3077, NGC 2961, NGC 2959 and NGC 2976.

 

One of the objectives for this wide field image was to capture the IFN (Integrated Flux Nebula) that surrounds the region. This is why over 50 hours of imaging was taken to pick up the weak background signal.

 

Primarily the RGB was taken using a UV/UR cut filter during the moonless nights, and then the Ha data was added from a narrowband session using the Optolong L-Extreme 3nm filter during brighter moonlit nights. This narrowband data improves the definition of the red Ha jets being ejected from the galaxy core go M82.

 

Imaged from my home in Gergal, Spain over 8 nights in February and March 2023.

This is the California Nebula (NGC 1499 or Sharpless 220) an emission nebula in the constellation Perseus that I imaged back in September. This nebula is about 1,000 light years from the Earth. The nebula is being lit up by the star Menkib which is the brightest star in the image. During the imaging sessions high clouds passed overhead causing the fuzzy display shown.

Horsehead nebula IC 434, is a beautiful emission nebula composed mainly of ionised Hydrogen gas that emits red light. The dark shape that resemble a horse head is a dark nebula that hides the stars behind it (B33). On the left, is another Hydrogen glowing gas cloud called Flame nebula NGC 2024. Alnitak star is shining just above the Flame nebula. Alnitak is one of stars that forming Orion belt (The Hunter). Also, this region of the sky contains a Reflection nebula just below the Horsehead nebula. NGC 2023 is a blue reflection nebula, it is composed of clouds of gases that reflect the young stars light to glow in blue light. All those nebulae are about 1500 light years from Earth.

First discovered by Edmond Halley in 1714. It was 50 years later when Charles Messier added the cluster to his list of objects that he was not interested in, giving it the designation M13.

 

The cluster is 25,000 light years away from us and can be found in the Constellation Hercules. Giving it it's more prestigious title of 'The Great Cluster in Hercules'.

 

M13 is one of the brightest globular clusters visible to us, especially from the Northern hemisphere. Containing over 100,000 stars it is quite easy to detect with a modest pair of binoculars and a dark sky.

Leave a comment below if you find it with some binoculars.

North America and The Pelican nebula.

Taken from a light polluted area (Bortle 7) using a 3nm narrowband filters, about 5 hours per filter.

 

Although the image is nicely detailed I strongly consider to add another 5 hours per channel to reduce the noise and enhance the details.
