Imaged during the night of 2-3 March in continuing clear skies here. This is my take on the aptly named Jellyfish nebula complete with bell-shaped body and trailing tentacles!

 

Also catalogued as Sharpless 248 this object is actually the galactic remnants of a supernova which may have occurred within the broad timespan of 3 - 30000 years ago.

 

The nebula is located in the constellation of Gemini and the bright star is Eta Geminorum also known as Propus or Tejat Prior - a Class M star which actually forms part of a triple system.

 

The Jellyfish lies at a distance of around 5000 lightyears and is around 70 lightyears in size.

 

This is a straight broadband image taken with my Esprit 120ED refractor and a ZWO 2600MC camera. I used Skywatcher's 0.77x focal reducer.

Rho Ophiuchi Cloud Complex

........................................................

Located at about 500 light-years from Earth, Rho Ophiuchi is undoubtedly one of the most spectacular and colorful parts of the night sky.

Emission nebulae, reflection nebulae, dark nebulae or star clusters, all can be found in this small part of the sky. There is also a star nursery, practically the closest to Earth, and not to forget Antares (in the yellow area of the attached photo), a giant star, 700 times larger than the Sun, and 10,000 times brighter.

A book could be written about this area, so I will stop here with the description. I hope I will be lucky enough to repeat the experience at the next new moon.

It would have been amazing seeing this week’s total solar eclipse from Exmouth in Western Australia. From my location on the southeast coast of Australia, though, the event was a partial eclipse, meaning the Moon’s path between the Sun and my viewing position only obscured a small portion of the Sun’s disc. Unfortunately, the eclipse was partial for me in another sense. Clouds covered the sky for nearly ninety of the one hundred and twenty minutes of the eclipse.

 

When the clouds thinned out, I got a few images, including this one shot at the point of maximum eclipse. The clouds gave the Sun its mottled look and possibly made this a more interesting photo. In the enlarged inset, you can see the sunspot area known as AR3282, and the two large blobs at either end of this feature are about the same size as the Earth.

 

I’d hoped for better–and more–shots than I captured, but something’s better than nothing, right? I captured this photo with a Canon EOS 6D Mk II camera attached to my SkyWatcher 8” Dobsonian telescope—with a Thousand Oaks solar filter fitted—using an exposure time of 1/160 second @ ISO 800.

Following on from my previous aircraft/moon image this follow-up shows the full sequence of the aircraft's transit across the face of the rising gibbous moon.

 

The Easyjet Airbus A320 had taken off from Belfast International Airport (BFS) 4 mins previously, enroute to London Gatwick (LGK)

 

I was in the fortunate position of actively doing lunar imaging when the aircraft passed through!

 

My camera was operating at 3 frames per second so I was able to capture the aircraft's ingress, transit and egress!

 

The first image has captured the aircraft's navigation lights and it is fascinating to see the eddies and disturbances created on the moon's image by the plane's hot exhaust gases.

 

Imaged with a Skywatcher Esprit 120ED Apo Refractor and a ZWO 2600MC camera and a lot of luck!!

 

As always many thanks for looking. Always appreciated!

Following reports of this comet in outburst in the latter half of Dec 2015/early days of 2016, the first opportunity I had to get a look at home was 7 January 2016. A very clear but windy night with seeing approx 5/10.

 

Through my binoculars: Estimated mag. 8.5, coma diameter 4'.

Comet was passing very close to a mag 14.5 star at the time which threw me off quite a bit during processing.

NGC 7293 a.k.a. Helix Nebula

…………………………..

Helix Nebula, also known as the Eye of God, is a planetary nebula that was discovered about 200 years ago by German astronomer Karl Harding and can be found at 650 light-years from Earth, in the constellation of Aquarius. Specialists believe that Helix appeared due to a star relatively similar to the Sun, a star that reached the last stage of its existence and began to release large amounts of energy and gas in the outer space. The calculated diameter of this nebula is almost 3 light years, and the expansion speed exceeds 20 miles / sec.

In the northern hemisphere ( 45 degrees ) Helix can be observed / imaged only during the summer, August being the best month for this, but because it does not rise much in the night sky, those passionate about astrophotography and / or visual observations must use locations with a good opening towards the south, and away from the light pollution of the big cities.

Red hydrogen emission and blue reflection nebulae, dark molecular clouds and a bright star sitting in the middle, flooding the scene its yellow light... Sounds like the Rho Ophichui region?

 

Sure. There is, however, another smaller, but similarly colorful area in the sky:

Meet the Cave Nebula!

 

Officially designated Sh2-155, the Cave Nebula in the constellation Cepheus, is a diffuse nebula of ionized hydrogen with ongoing star formation activity, at an estimated distance of 2400 light-years from Earth. It lies within a larger complex containing emission, reflection, and dark nebulosity.

 

The name "Cave Nebula" for Sh2-155 was coined by Patrick Moore, presumably derived from photographic images showing a curved arc of emission nebulosity corresponding to a cave mouth. Earlier, the name was already used to refer to another brighter but unrelated reflection nebula in Cepheus, known as Ced 201. The name's application to Sh2-155 has come into vogue through the nebula's inclusion in Moore's Caldwell catalogue as object Caldwell 9.

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.

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.

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.

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.
