NGC 281 a.k.a. Pacman Nebula

…………………………..

Discovered nearly 130 years ago by E.E. Barnard, an American astronomer, NGC 281 is an emission nebula that spans nearly 100 light-years and is located about 9,500 light-years from Earth in the constellation Cassiopeia.

NGC 281 is also known as the Pacman Nebula for its resemblance to the video game character.

Although it is an emission nebula, the Pacman Nebula is bright enough to be seen with a medium-sized telescope, preferably from low-light locations.

Imaged with my ZWO ASI071 camera on Skywatcher Esprit 120 telescope, this time with a Televue 2X Powermate.

I had only recently purchased some narrow-band filters and was keen to give them a test run; for this, I chose NGC281. The aim was initially to capture data in LRGB along with Ha, OIII, and SII; the telescope and weather had other plans. I hadn’t looked at the data since the initial night, and using a process in Pixinsight inspired by Cuiv’s recent mastering Pixinsight YouTube video, I was able to bring together this HOO image of the nebula; it is a target that I plan to revisit this winter to capture more Ha and OIII, along with LRGB and SII data.

 

NGC 281, IC 11 or Sh2-184 is a bright emission nebula and part of an HII region in the northern constellation of Cassiopeia and is part of the Milky Way’s Perseus arm. This 20×30 -sized nebulosity is also associated with open cluster IC 1590, several Bok globules and the multiple star B 1. It collectively forms Sh2-184,[3]spanning over a larger area of 40 arcmin.[4] A recent distance from radio parallaxes of water masers at 22Ghz in 2014 is estimated to be 2.82±0.20 kpc. (9200 ly.) from us.[5] Colloquially, NGC 281 is also known as the Pacman Nebula for its resemblance to the video game character. Source: Wikipedia

Messier 104 a.k.a. Sombrero Galaxy

…………………………..

Discovered 250 years ago, the Sombrero galaxy (The Hat) is an elliptical galaxy located just over 30 million light-years from us and can be seen between the constellation Virgo and the constellation Corvus. According to measurements made by specialists in the field, M104 has a diameter of about 40,000 light-years, being about 3 times smaller than our galaxy. The name of the Hat is given both by the angle from which we can see it, and due to that prominent ring of cosmic dust that surrounds this galaxy and which is also the main source of new star formation. Regarding the nucleus of this galaxy, with the help of special infrared measurements it was found that in the galactic center of M104 there is a massive black hole, larger than in any other galaxy located within a radius of 40 million light years around the Milky Way.

Reasonably clear skies on the night of 19-20 March allowed me to try to image NGC 2403 in the constellation of Camelopardalis.

This is my first attempt at imaging this system.

 

The galaxy lies at a distance of around 8-9 million light-years from us. The galaxy was discovered by William Herschel in 1788 and is an intermediate spiral system.

 

The galaxy bears a striking resemblance to its more illustrious colleague, M33 The Triangulum Galaxy, having the same somewhat flocculated appearance but also a plethora of pinkish-reddish star forming HII regions.

 

The galaxy is considerably larger than M33 making it one of the largest HII regions observable.

After a long break from doing astrophotography, I decided to spend some time last night and use the new gear I recently got shooting a popular and relatively easy target, The Pleiades. It does appear the lens was slightly off on focus, but whatever. Most people will never pixel-peep it anyways. It all worked great, and it felt good to capture the heavens again.

I polar aligned my mount using SharpCap Pro. My Sony a7RIII and adapted Nikkor 500mm f/4 P AI-S were mounted on an ADM vixen rail and secured to the SkyWatcher EQ6-R mount. The guide scope/camera was attached to the camera's hot shoe. I used PHD2 to autogude during the imaging session. DeepSkyStacker was used to combine all frames, and then I processed the TIFF file in Photoshop. I stretched the 32-bit file and used Gradient XT on the image. I then made it a 16-bit file and stretched it in levels, then curves. I used the color sampler tool and levels to do my best to help keep colors accurate. I then used my skillset and relied on Astronomy Tools Action Set and Topaz Denoise and Sharpening to give the image a polished look. I brought it into Lightroom to do final color corrections and add EXIF data.

Have not been very well lately and unfortunately it is ongoing. So haven't been about.

 

I did managed to get some imaging done this month (weather has been hopeless as usual - so not helping!)

 

This is an image of the emission nebula, "The Great Orion Nebula" M42, with the attendant reflection nebula "The Running Man" Sharpless Sh2-279 to the right. Both these beautiful systems are found in the sword area of the magnificent constellation of Orion.

 

M42 is one of the brightest nebula in our skies, lying at a distance of over 1300 light years. This massive cloud of glowing gas and dust is a stellar nursery and is the closest massive star forming region to earth.

 

The Running Man Nebula to the right is so-called because many observers liken its appearance to a human running with arms flailing! (you might need to use a bit of imagination!) This is a reflection nebula. This means it is only visible to us because light from an illumination source, such as embedded stars, lights up the surrounding gas and dust.

 

Extensive dust clouds can be seen throughout the whole image.

 

Imaged with a Skywatcher Esprit 120ED refractor fitted with a focal reducer (scope at f5.4) and a ZWO 2600MC camera.

This is an image of The Sunflower Galaxy. Located in the constellation of Canes Venatici the galaxy lies at a distance of around 27 million light-years.

 

Discovered by Pierre Méchain in 1779 the galaxy was catalogued by Charles Messier as M63 in his catalogue. It is also known as NGC 5055.

 

The Sunflower Galaxy is an example of a flocculent spiral. Instead of well-defined spiral arms it appears to have many discontinuous arms giving a loosely lumped appearance hence the name.

 

A large, prominent dark dust lane is also visible at the front margin of the Sunflower.

  

Imaged with a Skywatcher 120ED Triplet Apo fitted with a field flattener. Images were captured with a ZWO 2600MC camera.

 

A total of 5.8hrs guided exposures during the night of 1-2 April. An annoying breeze during capture caused some guiding issues but you take what you get here!

  

Calibrated with temp. matched Darks, Dark Flats and Flats.

 

Thanks for looking!

The Eastern Veil nebula is a cloud of heated and ionized gas and dust in the constellation of Cygnus, located at around 1470 light-years from Earth. It is part of the Cygnus Loop which is a 7000 years old, faint supernova remnant, covering roughly 3° on the sky (almost 6 full moons). The red hues in this image are from ionized hydrogen gas clouds, emitting light in the H-alpha wavelength, while the cyan hues are from oxygen ions.

A somewhat curtailed (very frustrating!) imaging session yielded this image of the iconic Great Orion Nebula M42.

 

Lying just over 1300 light years distant M42 is one of the brightest nebula and is visible as a fuzzy patch lying below Orion's belt as the middle "star" in Orion's sword.

 

This is only my second light with my new ZWO 2600MC camera and the forecast for 10th February looked good here - how wrong it was....

 

I only managed to get 7 usable subs of 1min each in the bitter cold before cloud and snow flurries ended my efforts!

 

Pretty pleased with what I was able to acquire with 7 subs including a satellite trail along the bottom (perhaps Courtesy of Mr Musk.....)

 

Hopefully I will get a much longer session with this camera soon.

Bodes Galaxy (M81) and the Cigar Galaxy (M82) are known to form a beautiful pair of galaxies. M81 is strongly interacting with M82 and a third galaxy, named NGC 3077. This galactic trio was the target of this image.

 

M81 is a spiral galaxy about 12 million light-years away, in the constellation Ursa Major. It is the main galaxy of the 'M81 Group', which includes 60 Galaxies.

 

M82 is a starburst galaxy and a member of the M81 Group. It is it is about five times more luminous than the whole Milky Way and has a center one hundred times more luminous than our galaxy's center. The starburst activity is thought to have been triggered by interaction with neighboring galaxy M81.

 

NGC3077 is thr small galaxy on the left and a member of the M81 Group as well. Despite looking much like an elliptical galaxy, it is a spiral galaxy. It shows wispy edges and scattered dust clouds that are probably a result of gravitational interaction with its larger neighbors.
