Alnitak and the Horsehead nebula - by Mike O'Day ( 500px.com/mikeoday )..Orion's Belt - centred on "Alnitak", is a 1.7 magnitude triple star 740 light years from Earth and appears at one end of the belt. ..The Flame nebula ( cat: NGC 2024 or Sharpless 2-277 ) ( lower centre left of the image) glows yellow-pink due to the ionising radiation that comes from Alnitak. Seen from Earth, the Flame nebula is behind Alnitak and around 80 light years further away from Earth. ..The Horsehead nebula ( cat: Barnard 33 ) ( centre right of the image ) is a dark dust and gas cloud that is only visible from Earth due to the backlight illumination and silhouetting caused by the bright pink glow from the ionised hydrogen gas in the emission nebula IC 434. The bright blue reflection nebula below and to the left of the Horsehead is NGC 2023. ..Details:..Skywatcher Quattro 10" f4 Newtonian. .Skywatcher AZ Eq6 GT Mount .Orion 80mm f5 guide scope and auto guider - PHD2. .Baader MPCC Mark 3 Coma Corrector, no filter.Nikon D5300 (unmodified)..14bit NEF, Long Exp.

The Eagle Nebula (Messier 16 or M16) is nebulosity surrounding a young open cluster of stars in the constellation Serpens. The dark center of the nebula was made famous as the "Pillars of Creation" when imaged by the Hubble Space Telescope. It is approximately 5700 light years from Earth.

While the Shot looks like the Coloured camera shot but it is far from it. This is the filters in the Hubble pallet but using the Foraxx version which removes all the green and brings out the red. The finer details in the wisps is certainly far more visible that the coloured shot. This pure Narrowband Background and RGB (Coloured camera) stars added.

Seeing conditions were fairly good with the target about 39.8° above the horizon at the time of capture.

M45, The Pleiades, or Seven Sisters, it’s an open star cluster in Taurus.

 

I photographed this on the 23rd December 2021 and managed to capture 49 minutes. Due to the field of view of my setup, I had to capture this as a mosaic across 4 separate panels.

 

This came out much better considering how minimal amount of exposure time I had between those 4 panels.

 

This was also a good test for Astro Pixel Processor’s new mosaic algorithm and speed increase, which I can say worked fantastic over the previous version!

NGC 55, is a Magellanic type barred spiral galaxy located about 6.5 million light-years away in the constellation Sculptor. Along with its neighbor NGC 300, it is one of the closest galaxies to the Local Group, probably lying between the Milky Way and the Sculptor Group. It has an estimated mass of × 10¹⁰ M☉. Wikipedia

First Look at the NEQ6 pro, this is 44 shot on the only night in lock down to be able to shoot now its back into rain and clouds.

44 Shots 10min each till the tree got in the way and clouds came over in the early hours of the morning.. when you see the number of stars in this one shot really puts thing into perspective.

This is a second look at this Nebula with a whole new Camera QHY183C a replacement for the ZWOASI183MC that was faulty. I could focus automatically with this camera hence the detail in the eye is much better than the first one with the ZWO. This camera took a bit to get use to as I had to change wires and ports on the computer to get this to run and download photos.

I grabbed this shot on the evening of 5/15, through some surprisingly thick high-level clouds just about a minute before it entered totality. The clouds resulted in a neat aura/halo effect in the photo.

 

I'm just thankful to have gotten anything since we were surrounded by storms at that moment. Distant lightning was lighting up the upper atmosphere as I snapped this shot from my front yard. I hope you enjoy!

Referred to as Bode's Nebula, it is however, a spiral galaxy located close to the Big Dipper or Plough asterism in Ursa Major. It has a close companion galaxy M82 the Cigar galaxy, so close together, they are often imaged as a pair.

 

Lying about 12 million light years from Earth and about 90,000 light years across. Binoculars will pick up M81 as a faint fuzzy patch of light under reasonable sky conditions.

First discovered by a German astronomer by the name of Johann Elert Bode in 1774, hence Bode's Nebula. At the time no one had any clue it was a whole other galaxy.

 

Johann Elert Bode is the person responsible for all the butt jokes we astronomers have to endure. He's the person that gave the planet Uranus it's name. After William Herschel discovered Uranus, he originally named it Georgium Sidus (George's star), has it was first thought by Herschel to be a star or comet.

At a certain angle of the sun's illumination a number of volcanic lunar domes are visible near the craters of Hortensius, Milichius & T. Mayer. This area is also referred to by the popular name "Domeland"

 

A two pane mosaic obtained with my Skywatcher 254mm Newtonian, Tal 2x Barlow and a recently purchased ZWO ASI385MC.

 

The pane with the Hortensius Domes is a much better quality compared to my previous capture uploaded with the Copernicus crater.

 

4000 frames captured on each pane using Firecapture. Then approx. 1400 to 1500 frames stacked with AutoStakkert! 3.1.4.

For a reference to scale, the diameter of the crater Hortensius is 15Km (9 miles).

The Orion Nebula is a diffuse nebula in the constellation of Orion and is one of the brightest nebulae. It is also visible to the naked eye in the night sky. (It is the middle "star" of the handle of the saucepan.) It is located approximately 1,344 light years from Earth and is the closest region of massive star formation.

 

This is just a short image run of RGB only as orion didn't rise over the roof of the house next door until late in the evening. It is also probably one of the most photographed nebulae in the night sky.

Imaged on the evening of 14.07.19. A beautiful moon presented a target to good to resist.

 

The moon was just over 12 days old when this image was taken and is presenting at just over 96% illuminated. Also known as a gibbous phase.

 

This image represents the first taken (first light) with my new Skywatcher Esprit ED120. The camera used was a Nikon D5300.
