Discovered in 2011 by French astrophotographer Nicolas Outters, the Squid Nebula (Ou4) is distinguished by its elegant bipolar shape and the vivid blue glow of doubly ionized oxygen (Oiii). It is nestled entirely within the reddish hydrogen-rich emission nebula Sh2-129, also known as the Flying Bat Nebula.
Recent research indicates that Ou4 lies roughly 2,300 light-years from Earth and resides within Sh2-129. This makes Ou4 a dramatic outflow, originating from HR 8119, a triple system of hot, massive stars at the nebula’s core. With an enormous physical size of nearly 50 light-years, the Squid Nebula stands as one of the largest and most intriguing emission structures in the night sky.
Capturing the Squid Nebula is a real challenge and requires very long integration times over several nights... The perfect challenge to test my new deep space imaging rig.

This is a montage of the best bits of 2016 ..... It's been an interesting year for sure and I've had some imaging fun!
2017 is already turning into an interesting year, with things in the pipeline that I am looking forward to.
There are many hundreds of hours of total exposure time in this complete montage. Some of the images have been published in magazine and one of them got a NASA APOD as well.
I hope you enjoy looking over it as much as I've enjoyed the imaging and processing time spent doing each and every image on here.

The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus, at about 2400 light years from us.
It constitutes the visible portions of the Cygnus Loop,a supernova remnant, many portions of which have acquired their own individual names and catalogue identifiers. In modern usage, the names Veil Nebula, Cirrus Nebula, and Filamentary Nebula generally refer to all the visible structure of the remnant, or even to the entire loop itself. The structure is so large that several NGC numbers were assigned to various arcs of the nebula. There are three main visual components: 1. The Western Veil (also known as Caldwell 34), consisting of NGC 6960 (the "Witch's Broom", Lacework Nebula, "Filamentary Nebula"; 2. The Eastern Veil (also known as Caldwell 33), whose brightest area is NGC 6992, trailing off farther south into NGC 6995 (together with NGC 6992 also known as "Network Nebula"; 3. Pickering's Triangle (or Pickering's Triangular Wisp), brightest at the north central edge of the loop, but visible in photographs continuing toward the central area of the loop.
The source supernova was a star 20 times more massive than the Sun which exploded between 10,000 and 20,000 years ago. At the time of the explosion, the supernova would have appeared brighter than Venus in the sky, and visible in the daytime. The remnants have since expanded to cover an area of the sky roughly 36 times the area of the full Moon.

The cluster and nebula lie at a distance of 5,000 light-years from Earth and measure roughly 130 light years in diameter. The radiation from the young stars excites the atoms in the nebula, causing them to emit radiation themselves producing the emission nebula we see.

Discovered in 1786 by William Herschel, the North
America Nebula shows its characteristic shape only in wide field astrophotographs.
The North America Nebula is separated from the Pelican Nebula by a dark dust cloud catalogued in 1962 as L935.
It took until 2004 for astronomers to identify the star that ionizes both the North America and the Pelican Nebula. The light of the inconspicuous star, named J205551.3+435225, is almost entirely blocked by the dark cloud L935. As J205551.3+435225 lies just off the “Florida coast” of the North America Nebula, it has been more conveniently nicknamed the Bajamar Star ("Islas de Bajamar," meaning "low-tide islands" in Spanish, was the original name of the Bahamas).

This is the 2nd brightest globular clusters after Omega Centauri and one of the most massive in our galaxy. The cluster has a very dense core where the light falls off to a point vs reaching a flatter profile near the center as in a typical globular cluster. It has been proposed a massive black hole may reside near the center. In the night sky this object is about the size of the full moon.

Mars reflects the sun's light and is ~22 light minutes from Earth. The Pleiades is an open star cluster that is ~ 442 light years away from us. While these two are so different, both of them are prominent and easy to spot in the night sky. It’s very cool to witness the two so close to each other. I knew this was happening, but my life and job have been so busy lately it slipped my mind until it was basically happening already.
Step outside tonight and take a lookup. You can find this event just ahead of the constellation Orion. The next time these two will be near each other in our night sky again in 2038!

My mount was polar aligned with SharpCap (what an amazing system for aligning). I'm not comfortable using my SCT as my lens yet. My solution is to piggyback my Sony a7RIII and adapted Canon FD 300mm f/4 L on a ADM dovetail rail on the top of my optical tube. I used DeepSkyStacker to combine all frames and then 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 in level, then curves. I used the color sampler tool and levels to do my best to keep the background space black. I then using my skillset and relied on Astronomy Tools Action Set, and dodging and burning a bit to give the image the finishing touches.

After listening to another lecture on quantum physics, I realized that I hadn't spent much time in this area... We will make up for it ! ;)
You are looking at a galaxy edge-on that is located 30 million light years away in the constellation Andromeda.
Consider our own Milky Way galaxy which is a huge disk of stars measuring 100,000 light years in diameter but only 1000 light years thick. So galaxies are quite thin relatively speaking.
A so-called edge-on view of a galaxy is like looking at the edge of a dinner plate and trying to see to the other side through the most dense portion. In the case of a galaxy this is mostly interstellar dust which is the dark linear region you see here. NGC 891, also referred to as the “silver sliver” galaxy, is very similar to our own Milky Way in size and luminosity.
The next time you see the Milky Way in a dark sky remember you are actually looking at it edge on also but this time you are on the inside looking out!

In-depth Description:
This is a dynamic looking region of the constellation Auriga where spherical nebulas appear hurled to crash into each other. This image includes the nebulae Sh2-232, Sh2-235, Sh2-231, Sh2-234 and LBN 796, among others, and the open star clusters M38 and M36.
The eyeball looking nebula (Sh2-232) has been mistaken for a planetary nebula, but none of the round or semispherical objects in this image are actually classified as PNs (per Galaxymap and SIMBAD). In fact, the big fuzzy ball in the lower left center (right above cluster M36) does not seem to have any designation at all and is merely a part of the greater nebula LBN 796. A 2012 study suggests that these unusual forms are all part of an expanding shell, the result of an ancient supernova.
These nebulae are all features of a larger molecular cloud located 1800 pc from us. By comparison the two clusters are much closer: M36 (bottom center) is 1330 pc distant, and M38 (center right) lies only 1066 pc away.

IC 2177 a.k.a. Seagull Nebula.
.....................................................
IC2177 is a region of nebulosity that spans about 240 light-years along the border between the constellations Monoceros and Canis Major, at a distance of about 3,800 light-years from Earth.
This is not the first time I have shot at the same targets with both the color and mono cameras, but it is the first time I have used both data sets for a single image. The color camera data was used as the Luminance channel, along with the Halpha data, and for the final result I used an LRGB approach.

NGC 7635 a.k.a. Bubble Nebula
……………………………................
Space is full of things / situations / events that intrigue us, NGC7635 being one of those. In short and for everyone to understand, a massive star is caught in a "bubble". This star is almost 50 times larger than the Sun and the emitted radiation is about 1 million times stronger than it, producing a stellar wind that exceeds 5 million km per hour, wind that pushes dust and gas outward creating thus a shell or a bubble, a situation that obviously led to the popular name of this nebula.
As general information, the Bubble Nebula is an emission nebula with a diameter of about 7 light-years, located in the constellation Cassiopeia, at a distance of over 7000 light-years from Earth and it was discovered in 1787 by the British astronomer, William Herschel.
Specialists believe that in a short time ( meaning in the next 10-20 million years), the "guilty" star will consume its energy resources, and will explode, forming a supernova.

Less than a week since our last image, and the tail of Comet C/2025 A6 Lemmon is stealing the show! Stretching longer and more vibrant, this comet is a stunning sight as it blazes through its orbit. ✨
Captured on October 22, 2025—just one day after its closest approach to Earth at about 0.60 AU (90 million km)—this latest view highlights the comet’s growing tail.
C/2025 A6 Lemmon is a long-period comet on an elliptical, retrograde orbit inclined at 143.7° to the ecliptic, taking it on a journey of roughly 1,350 years around the Sun. Currently, it’s hurtling toward perihelion on November 8 at a mere 0.53 AU from the Sun (closer than Venus!), where solar heat will vaporize its icy nucleus and fuel even more dramatic displays. This passage will shorten its orbital period to around 1,150 years—a true cosmic wanderer! 🌌

NGC 4565 a.k.a. Needle Galaxy
.....................................................
NGC 4565, better known as the Needle Galaxy, is a spiral galaxy located in the constellation Coma Berenice, at about 40 million light-years from Earth. This galaxy is larger than the Milky Way, with a diameter of 130-150000 light-years, and appears to be brighter than Andromeda. Due to its shape, in addition to Needle, NGC4565 is also known as Flying Saucer Galaxy or Berenice's Hair Clip. Very well known and popular in astrophotography, Needle Galaxy can be imaged with a small telescope, but a longer focal length would lead to a more detailed result.

Processing Pixinsight 1.8 - I have had this data set around for a while and have never been happy with my processing results.
Prospetticamente attorno ad una delle più luminose stelle del cielo, la stella multipla e variabile Gamma Cassiopeiae (γ Cas), chiamata Tsih o Navi, si trova la regione di H II (idrogeno ionizzato) conosciuta con la sigla Sh2-185, e al cui interno spiccano due nebulose catalogate con le sigle IC59 e IC63.
Pensavo che riuscire a fotografare questa regione fosse una cosa più semplice invece devo ammettere che la nebulosità più debole di Sh2-185 è veramente molto evanescente e la presenza di gradienti causati da Inquinamento luminoso ha complicato le cose; quindi sono stato costretto mio malgrado ad utilizzare con decisione i tool di denoise per ridurre il rumore.
Ma ciò che ha reso più difficile elaborare questa immagine è stata la presenza della luminosa Gamma Cassiopeiae il cui riverbero abbagliava una parte dell'immagine e attorno alla quale c'era un antiestetico alone penso causato da riflessioni all'interno del riduttore 0.6X.
Ciò malgrado penso di aver raggiunto un discreto risultato.
________
Perspectively surrounding one of the brightest stars in the sky, the multiple variable star Gamma Cassiopeiae (γ Cas), called Tsih or Navi, lies the H II (ionized hydrogen) region known by the acronym Sh2-185, within which stand out two nebulae cataloged as IC59 and IC63.
I thought photographing this region would be easier, but I have to admit that the faintest nebulosity of Sh2-185 is truly very evanescent, and the presence of gradients caused by light pollution complicated matters; so, against my will, I was forced to vigorously use denoising tools to reduce the noise.
But what made processing this image more difficult was the presence of the bright Gamma Cassiopeiae, whose glare dazzled part of the image and which had an unsightly halo around it, I think caused by reflections within the 0.6X reducer.
Even so, I think I achieved a decent result.

The New General Catalogue of Nebulae and Clusters of Stars (abbreviated NGC) is an astronomical catalogue of deep-sky objects compiled by John Louis Emil Dreyer in 1888. The NGC contains 7,840 objects, including galaxies, star clusters and emission nebulae. Dreyer published two supplements to the NGC in 1895 and 1908, known as the Index Catalogues (abbreviated IC), describing a further 5,386 astronomical objects.
The clouds of IC 63 shown in the image, about 600 light-years distant, aren't actually ghosts. They are slowly disappearing though, under the influence of energetic radiation from hot, luminous bluish star gamma Cas to the upper right.
Gamma Cas is physically located only 3 to 4 light-years from the nebulae. Slightly closer to gamma Cas, IC 63 is dominated by red H-alpha light emitted as hydrogen atoms ionized by the hot star's ultraviolet radiation recombine with electrons. Farther from the star on the top border, IC 59 shows less H-alpha emission but more of the characteristic blue tint of dust reflected star light. (courtesy APOD 10/26/2024)
