The Cat’s Eye Nebula is a famous planetary nebula located in the northern constellation Draco. The nebula’s designation in the New General Catalogue is NGC 6543.

The Cat’s Eye is one of the most structurally complex nebulae known. It was formed around 1,000 years ago when a hot, bright central star expelled its outer envelope. It is sometimes also known as the Sunflower Nebula or the Snail Nebula. It lies at a distance of 3,300 light years from Earth.

There is an enormous but exceptionally faint halo of gaseous material surrounding the Cat’s Eye Nebula which is over three light-years across. Within the past years some planetary nebulae been found to have halos like this one, likely formed of material ejected during earlier active episodes in the star’s evolution – most likely some 50,000 to 90,000 years ago.

In my photo the Cat's Eye Nebula is the central, bright area. It is burnt out as I have probably overexposed the images but it means you can see the glow of the surrounding material.

The brightest of the knots in the nebula’s halo has its own entry in the IC catalogue: IC 4677.

Lower down in the image you can see NGC 6552 which is a barred spiral galaxy about 400 million light years from our solar system.

I wanted to image this nebula since I have seen this picture on astrobin www.astrobin.com/5l8pbx/

It looks absolute striking and way better than my own attempt. Guess mono and over double the exposure time doing their magic here.

If possible I will try to get a few more ours on this target, weather was an absolute catastrophe since early December for me, with only a few nights of clear skies.

The Flaming Star Nebula, also known as IC 405 or Caldwell 31, is a diffuse emission nebula located in the constellation Auriga. It is about 1,500 light-years away from Earth and covers an area of about five times the size of the full Moon in the night sky.The Flaming Star Nebula gets its name from the distinctive shape of the reddish-pink nebula, which resembles a fiery, flaming star. The nebula is primarily composed of hydrogen gas, which is ionized by the ultraviolet radiation from a nearby hot, young star called AE Aurigae. This process causes the gas to emit light, creating the glowing appearance of the nebula.In addition to the hydrogen gas, the Flaming Star Nebula also contains dust particles, which absorb and scatter light. This gives the nebula its intricate, filamentary structure and contributes to the overall reddish-pink color.The Flaming Star Nebula is a popular target for amateur astronomers and astrophotographers due to its striking appearance and relative brightness. It is best viewed from dark-sky locations using telescopes or large binoculars, and is particularly impressive when captured in long-exposure photographs.

M51, the Whirlpool Galaxy, is 31 million light years from Earth in the constellation Canes Venatici. It has a beautiful face-on appearance, as seen from Earth, enabling observers to make out its distinct spiral structure and luminous galactic core.

The spiral arms are packed with stars, gas and dust and make for the perfect conditions for new stars to be born, as that gas and dust coalesces, compresses and collapses to ignite star-birth.

In images of the Whirlpool Galaxy, hot young stars can be seen glowing bright blue along the arms, while older, yellower stars are seen glowing closer to the centre.

NGC 6543, also known as the Cat's Eye Nebula, is a planetary nebula located in the constellation Draco, approximately 3,300 light-years from Earth.

Its intricate shape and colourful appearance have earned it the nicknames the Cat’s Eye Nebula, the Snail Nebula, and the Sunflower Nebula.

It formed around 1,000 years ago, when an aging star reached the end of its life and expelled its outer layers of gas and dust into space. The ejected clouds of material now surround the hot, bright planetary nebula nucleus, which illuminates them. Those outer clouds are quite faint. I needed 4 hours with my Celestron C11 to capture this level of detail.

Planetary nebulae are relatively short-lived phenomena. They typically last only 10,000 years. The Cat’s Eye Nebula will gradually disperse over the next several thousand years and the central star will eventually cool down and slowly fade away as a white dwarf.

評審短評：

可能因為雜訊的關係，背景壓的有點太暗，進而導致暗星點呈現過飽和，同時因為降噪，讓塗抹感有點重。有保留星系中間的色彩，不過整體稍微偏綠。

Stephan's Quintet is a visual grouping of five galaxies of which four form the first compact galaxy group ever discovered. The group is visible in the constellation Pegasus.

Four of these galaxies are about about 300 million light years away. Because of the two dimensional nature of this image, the fifth member (to the left of the middle pair) appears to be with the others; but in fact it is “only” 40 million light years away, so it is not part of the more distant group.

You may recognise these galaxies from the opening scenes of the classic 1946 film, “It’s a Wonderful Life.”

The California Nebula is an emission nebula found in the Perseus Constellation. It is actually quite large, two or three times larger than the moon, but is very faint.

Another new target for me. Technically this photo came out pretty good. It is just not that interesting to look at for me. If I had framed it on the diagonal, I may have like it better. I did have trouble getting a good image at first, but then I tried a trial version of a different processing program that did a great job bringing out the detail. I guess I’ll be plopping down more money on this hobby yet again.

Messier 1 is better known as the Crab Nebula. Charles Messier originally mistook Messier 1 for Halley’s Comet, which inspired him to create his famous catalogue of celestial objects that might be mistaken for comets.

The Crab Nebula is an expanding remnant of a star's supernova explosion. Japanese and Chinese astronomers recorded this violent event nearly 1,000 years ago in 1054 AD, as likely did the Native Americans. The glowing relic has been expanding since the star exploded, and it is now approximately 11 light-years in width.

The orange filaments are the tattered remains of the star and consist mostly of hydrogen. The blue in the filaments in the outer part of the nebula represents neutral oxygen. These elements were expelled during the supernova explosion.

A rapidly spinning neutron star (the ultra-dense core of the exploded star) is embedded in the centre of the Crab Nebula. Electrons whirling at nearly the speed of light around the star’s magnetic field lines produce the eerie blue light in the interior of the nebula. The neutron star, like a lighthouse, ejects twin beams of radiation that make it appear to pulse 30 times per second as it rotates.

Cieli sereni 🌌

With the Perseid Meteor shower at its peak on 12 August 2024 I set up my camera with an Unleashed controller to take a series of 15-second exposures and hoped that a meteor would show up. One did.

I stacked all 86 photos with 30 darks in AstroPixelProcessor, processed them in PixInsight to bring out the detail of the Milky Way. That of course obliterated the meteor. So I then used Adobe Photoshop to reintroduce the meteor flash. Not ideal, but it shows what happened

The Elephant’s Trunk Nebula (IC1396), 05/30/2021

Weirdly last time I took the telescope out camping for the weekend the skies were exceedingly kind to me. The weather was forecast to be cloudy and I almost did not even bring my gear, let alone set it all up once I got on site. But the clouds buggered off so, what the hell, let’s give it a chance. One unfortunate thing however was that this target did not rise from behind the trees until after 12:30am. This totally put the damper on how much partying I got to do with my friends. However, the weather was so good I was able to shoot this object three nights in a row and it ended up being the most time I’ve sunk into a single image so far. I believe that this is the best image I’ve capture yet and it was definitely worth the effort!

The Elephant’s Trunk Nebula is in the constellation Cepheus and is about 2,400 light-years away from your couch. The “trunk” itself is over 20 light-years in size.
