My goal with framing this shot was to include the Dumbbell Nebula (tiny, but bright, on the left), the asterism Brocchi's Cluster (lower right, AKA Coathanger) and some of the well-defined dark nebulae in the region (upper right). Emission nebulae are also fairly prominent near the center.

In my view of the Draco Trio you see a close grouping of three very different looking galaxies. There is a spiral galaxy on the top, NGC 5985, the elliptical galaxy NGC 5982, and on the bottom is the edge-on spiral galaxy designated as NGC 5981. All are part of a large group of galaxies called the NGC 5982 cluster. This image is about four hours of collected data.

The well known nebulosity in Orion's Sword lies 1350 light years away from our solar neighborhood . This huge area of star formation is consisting mostly by hydrogen while the glow of the gas is caused from the energetic stars in the central region, the "Trapezium".
Almost 8.5 years after, I returned back to reprocess one of my very favorite deep sky objects. 52 exposures with different exposure times were combined in order to preserve as many details as possible due to the extended dynamic range. Nonetheless the famous "Trapezium" is unfortunately not distinguishable at this image.
Alignment and stacking took place in DeepSkyStacker and there was a lot of work then as usual in Photoshop.

I'm somewhat, not completely happy, with this one. Pulling out the dark nebulae and dust among all of the stars, with a not-completely-flat field and a light pollution gradient from shooting fairly low, was tricky.
I plan to shoot this extent again 1) when it is higher in the sky later this year, 2) possibly with 90 sec subs instead of 60 sec (although tracking was spot on with a 90% keeper rate at 60 sec), and 3) I might experiment with PixInsight to better emphasize the dark nebulae while deemphasizing the stars.
April 26 update: Cropped
Aug 8 update: Reprocessed using raw instead of out-of-camera jpeg. Definitely some advantages to using raw.
Aug 26 update: Reimaged when closer to zenith, 54 x 60 sec this time, the two versions are extremely similar (so I just replaced the older with this one) although this one has the edge in that dust cloud representation is more accurate. Processing with this cleaner data was much easier, and involved much less manipulation.
Sept 13 update: Reprocessed with Astro Pixel Processor. I like the colors a bit better, and after several reprocesses I've decided to leave the dust cloulds fairly dim, since I don't like how it turns out when I stretch too far. This is just a tricky extent - the dust is so dim. Maybe I'm finally going to leave it alone. I'm excited to tackle the Dark Shark and Wolf's Cave nebulae widefield again, but am going to reshoot since I don't have raw files.
Oct. update: Alright, I wasn't done. I couldn't help but give it another try. The nebulosity is now a bit brighter, the color of the iris is bluer, and the stars slightly more reduced. I also upped the contrast and saturation of the Ghost Nebula. Maybe I'm done now.
April 2020 edit: Still wasn't done. I upped the brightness and contrast of the dark nebulae a bit more.

Galáxia Espiral Barrada M 95
[English Below]
Das poucas galáxias que registrei até o momento, esta é a de menor tamanho aparente. Além de se tratar de um objeto sem grande brilho e tamanho aparentes (visto da Terra), infelizmente a poluição luminosa estava bastante acentuada na direção inicial (e em grande parte do caminho) do alvo, o que prejudicou o registro, dificultando o processamento. Também tentarei fazer mais frames para revelar melhores detalhes em uma próxima oportunidade. Vale o exercício. Este registro contém 2 horas e 36 minutos de exposição.
Messier 95 (NGC 3351) é uma galáxia espiral barrada, com braços quase circulares, localizada a cerca de trinta e oito milhões de anos-luz de distância na direção da constelação de Leão. É uma das galáxias menos brilhantes no catálogo Messier. Fonte: Wikipedia (adaptado).
====================================
Of the few galaxies I have recorded so far, this is the one with smallest apparent size. In addition to being an object without great brightness and apparent size (seen from the Earth), unfortunately light pollution was quite accentuated in the initial direction (and in most of the path) of the target, which impaired the registration, making processing difficult. I will also try to make more frames to reveal better details in the next opportunity. Worth the exercise. This record contains 2 hours and 36 minutes of exposure.
Messier 95 (NGC 3351) is a barred spiral galaxy, with almost circular arms, located about thirty-eight million light years away in the direction of the Leo constellation. It is one of the least bright galaxies in the Messier catalog. Source: Wikipedia (adapted).

M27, The Dumbbell Nebula was the first planetary nebula discovered by Charles Messier in 1764. It is located 1360 light years away in the constellation of Vulpecula and is about 2.8 light years in diameter. Our own sun will produce a planetary nebula like this in about 5 billion years time when the hydrogen and helium depletes and it collapses into a white dwarf.

So, I’ve been putting off autoguiding for a long time now, after a lot of research, reading and asking a bunch of noob questions I decided to dive into autoguiding this week. I recently purchased a ZWO ASI290MC camera for planetary and moon photography and decided it would make an awesome guide camera when not in use. At the time of purchase, I also grabbed the Canon EOS adapter, why not. The next step was deciding to either go with an off axis guider (OAG) or a separate guide scope. I almost purchased a Celestron OAG and at the last minute decided to try out my Canon 400mm f/5.6 lens as a guide scope.
I had a piggy-back camera attachment for my Meade 12” LX90 and used that to mount the ASI camera and Canon lens to the Meade telescope. I installed PHD Guiding v1.14.2 by Stark Labs (www.stark-labs.com) for the first trial run. I kept all the default setting and was thrilled with the initial results!
I’ve never been able to take longer than 15-second exposures unguided. During this initial run with default settings, I was taking 60-second exposures at ISO 3200 using my Canon 6D DSLR, below is the first light image of the galaxy M82 (28-minutes total exposure taken on February 20, 2017) in the constellation Ursa Major, also known as the cigar galaxy.
Needless to say I can’t wait to image again.
The second run will be using PHD2 Guiding 2.6.3 and possibly using a Canon 100mm f/2.8 lens for guiding. My thoughts are the f/2.8 lens may bring in additional guide stars and also take a little weight off the mount (that I can use for other attachments, lol).
Also known as NGC 7822, The Teddy Bear Nebula. Found in the constellation of Cepheus and lies about 2,500 - 3,000 light years away.
Can you see the 3D?
Stare at the middle of the image and try to go cross eyed. You should see a third image start to appear in between the two, whilst going ALMOST cross eyed, try to focus on the middle image.
Any luck?
Still struggling to see it?
Try moving a little further away from your screen.

The NEOWISE pics I've posted so far have been taken via a lens or small telescope on a static tripod, which limited exposure length. With the comet now visible against darker skies as the Moon wanes, I've used a star tracker here to allow longer exposures and therefore to bring out the comet's ion tail, seen here pointing towards the 12 o'clock position. (The thin line to the right of the comet is a satellite track that was on one frame).

Comet Iwamoto was at its closest to Earth this morning, so I headed out to dark skies southwest of Brisbane early this morning to photograph it. This is a FAST comet, so even though I only had 20 minutes worth of exposures I had to align them to the comet rather then the background stars,

There is a faint tail visible extending towards 11 o'clock.
This is a planetary nebula in the constellation of Lyra. Planetary nebula are so named because, they are small, round and look like planets.
A planetary nebula is a star entering the final phases of it's life cycle. The more massive stars go out in spectacular style as a supernova. The smaller stars, like that of our Sun. Enter their penultimate phase, that of a white dwarf star, with a little less pazzazz. Though they are no less beautiful.

After spending some time on M5 I thought it would be fun to try some widefield Milkyway shots. I had to rebalance and go through the alignment procedure for my scope. I switched the 500mm for a more modest 35mm f/1.4 lens. I decided to shoot it at f/2.8 so it wasn't just wide open and trust my mount that had been polar aligned with SharpCap to do it's thing. I wanted a bright star to help define the area of the sky, so I chose Altair which can be seen in the middle right of this frame and let the gear do it's thing.

Barnard 150 is a dark nebula, also known as the Seahorse Nebula, located in the constellation Cepheus. It is about 1,200 light years from Earth. The nebula is so thick that it absorbs all light from stars behind it, making it stand out against the background of the Milky Way.
The nebula is shaped like a seahorse and is visible in silhouette against a background of stars. It has three dense dust cores, which are star formation regions. These cores were cataloged by Lynds and named LDN 1082 A, B, and C. This is almost 6.5 hours of collected light.

It'd been awhile since I'd been astrophotographing - felt great to be out under the stars and a smokeless sky. Fall is a excellent time for widefield astrophotography in the western US - there's a decent amount of astronomic dark, plenty of clear nights, temperatures aren't too cold, and quite a few interesting widefield subjects are available.
My goal with this small mosaic (only 2 panels) was to capture both the Fireworks Galaxy (NGC 6946, tiny here, bottom left) and the Elephant Trunk Nebula (IC 1396) in the same extent, with all of the interesting nebulosity in between, most notably the dark nebula Barnard 150 (AKA the Seahorse Nebula) in the lower left, one of my favs.
Surprisingly, I didn't detect much of the red emission Flying Bat Nebula (Sh2-129, center), part of which actually appears bluish (?, at first I was excited that I might have detected the Giant Squid Nebula (OU4), but nope, the blue is not in the right place). Previously I had captured Sh2-129, albeit faintly, with this same set up in the same location.
Part of the reason for this is that I stopped my Samyang 135mm down a half stop to f 2.4 (which I usually shoot wide open at f 2), not to tighten up stars, but to flatten out the heavy vignetting a tad. It did make a difference, but I did also notice that the Elephant Trunk Nebula didn't show up as strongly as expected based on my previous imaging of it. I'm still undecided whether I'll stay with f2 or move to f2.4, might depend on the subject.
There is a decent amount of what appears to be blue reflection nebulosity around star HD 198793 in the upper left quadrant; looking at widefield images of others, I can also see this faintly, but I haven't been able to find any closer images of it yet and it isn't cataloged in my astronomy app (SkySafari 6 Plus). It's possibly a processing artifact although it doesn't appear to be one.

The Orion Nebula (also known as Messier 42, M42, or NGC 1976) is a diffuse nebula situated in the Milky Way, being south of Orion's Belt in the constellation of Orion.[b] It is one of the brightest nebulae, and is visible to the naked eye in the night sky. M42 is located at a distance of 1,344 ± 20 light years and is the closest region of massive star formation to Earth. The M42 nebula is estimated to be 24 light years across. It has a mass of about 2000 times the mass of the Sun. Older texts frequently refer to the Orion Nebula as the Great Nebula in Orion or the Great Orion Nebula.
The Orion Nebula is one of the most scrutinized and photographed objects in the night sky, and is among the most intensely studied celestial features. The nebula has revealed much about the process of how stars and planetary systems are formed from collapsing clouds of gas and dust. Astronomers have directly observed protoplanetary disks, brown dwarfs, intense and turbulent motions of the gas, and the photo-ionizing effects of massive nearby stars in the nebula.
