NGC 1491 is called the Fossil Footprint Nebula. It is a bright emission nebula and hydrogen (HII) region, located on the edge of a vast cloud region of neutral gas, about 10,700 light-years away in the Perseus arm of our Milky Way Galaxy in the constellation Perseus.

HII regions are well known for being places where new stars are born, and are created when ultraviolet radiation from hot stars ionizes the surrounding gas, causing it to glow in visible light. The surrounding dust is also heated by this radiation, so we also see it glow in infrared light.

The bright, blue star near the centre is illuminating the nebula while its strong stellar wind is “blowing” a bubble in the gas that immediately surrounds it. The intense radiation from the star is also eroding the gas clouds surrounding it.

The entire nebula is quite irregular with a subtle bite cut out of the nebulosity that creates a darker hollow, and a high surface brightness region as seen in this image. A faint, elongated haze extends from this patch past the star, giving an elongated appearance.

The Owl Cluster is a bright open star cluster located approximately 8,000 light-years away in the northern constellation Cassiopeia. It has the designation NGC 457 in the New General Catalogue and is listed as Caldwell 13 in Sir Patrick Moore’s Caldwell catalogue.

The Owl Cluster is one of the finest telescope targets in the northern sky. It is easy to find because it appears in the region of Cassiopeia’s W. NGC 457 is also popularly known as the E. T. Cluster, Dragonfly Cluster, Kachina Doll Cluster, and Phi Cassiopeiae Cluster. I'll go with Owl Cluster as it is easier to spell.

The brightest members of the Owl Cluster are blue stars which are hot, massive, luminous stars that burn through their supply of fuel quickly and evolve into giants or supergiants within only a few million years. They have very short lives due to their high mass. The most massive of these stars will end their lives as supernovae, while others will cast away their outer layers to form planetary nebulae and slowly fade away as dim white dwarfs.

NGC 457 gets its most common nicknames – the Owl Cluster and the E.T. Cluster – because of two bright stars that appear in the same field. These two stars look like a pair of eyes, while the fainter stars form an outline of an owl - or the popular character E.T. from Steven Spielberg’s 1982 film.

This image was taken by integrating 20 two-minute exposures using my C11 telescope. That is not long for astrophotography, but the camera sensor picks up light from the stars much faster than the faint glow from nebulae.

On the 4th April 2023 the nearly full moon was casting its light across the sky, but up in the Northern constellation of Cepheus the Iris Nebula was still visible.

Many of the nebulae visible in the night sky are emission nebulae since they are clouds of dust and gas that are hot enough to emit their own radiation and light. The Iris Nebula or NGC 7023, is a reflection nebula. This means that its colour comes from the scattered light of its central star, which lies nestled in the abundant star fields of the constellation Cepheus. Located some 1,400 light-years away from Earth, the Iris Nebula’s glowing gaseous petals stretch roughly 6 light-years across. You can also see extensive streams of brownish dust and gas obscuring the distant stars beyond this nebula.

I managed about two hour on this target in the small hours of the morning before finding myself falling asleep. Stayed awake just long enough to pack up all my gear and in bed by 4:30 am.

There is something wrong with this hobby.

Despite the light pollution from the bright moon I spent about four hours on this nebulous target before it dipped too low in the sky. The larger, predatory looking nebula is IC 417 and the smaller, brighter nebula is NGC 1931.

This fun pair are sometimes called the Spider and the Fly nebulae.

IC 417 is an emission nebula in the constellation Auriga, lying about 10,000 light years away. The glowing centre of the nebula is energized by the hot, massive blue stars embedded within and it is a hotbed of new star formation.

NGC 1931, the Fly Nebula (towards the top) is an emission and reflection nebula, and has been referred to as a miniature version of the Orion Nebula, as it shares some of the same characteristics.

Western Veil Nebula (Caldwell 34), 06/25/2020

This object is part of a super nova remnant from a star that was 20 times more massive than the sun. When that star blew up some 10,000 to 20,000 years ago, it left behind ionized gas and dust that has expanded to cover an area of the sky roughly 6 times the diameter of the Moon. This picture is only one small part of that explosion.

This night was kind of a last-minute decision. I looked outside and saw clear skies so I quickly setup the gear. It was my first night using some new toys, a new light pollution filter and an Asiair Pro computer. The new equipment worked great but I did have a few issues. I had my gain set to 200 for some reason and the polar alignment was crap. But I think I salvaged the data and the image turned out pretty good.

La Nebulosa Elica o Occhio di Dio (NGC 7293) la quale si trova nella Costellazione dell’Acquario è uno degli esempi più spettacolari di nebulosa planetaria, creata da una stella morente che un tempo era simile al Sole. La nube ha una geometria sorprendentemente complessa, che include filamenti radiali, anelli esterni e addensamenti gassosi di ignota origine. Quando il combustibile necessario per le reazioni di fusione nucleare si esaurisce, le stelle di massa medio-piccola vanno incontro alla fine della loro vita gloriosa, espellendo gli strati gassosi esterni e lasciandosi dietro un nucleo denso e caldo, una nana bianca, Il puntino bianco visibile al centro della nube è proprio la densa nana bianca.

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.

Not exactly thrilled with this, but just another learning experience.

Andromeda Galaxy (M31), 09/27/2020

Took advantage of the unexpectedly clear skies and went to Belfair Start Park for a few nights. Last month I took a picture of M31 with my small system (T5i, 200mm lens and a star tracker) and I thought I’d compare it to my full-size setup. Yep, you guessed it, it’s a much better photo.

M101, o NGC 5457 è conosciuta anche come la Galassia Girandola, nome, che le deriva dalla sua conformazione a spirale, si trova nella costellazione dell'Orsa Maggiore. A 19 milioni di anni luce di distanza,in condizioni eccellenti, M101 può essere osservata anche con un semplice binocolo; infatti, grazie alla sua estensione e alla sua relativa vicinanza a noi, M101 è una delle galassie più brillanti del cielo.

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.
