The Crab Nebula is a supernova remnant that lies some 6500 light years away in the constellation Taurus. The nebula was discovered in 1731 and has the 1054 supernova event recorded by Chinese astronomers as it's progenitor. At the heart of the nebula is the Crab Pulsar, which is a neutron star some 18 miles across and spins 30 revolutions per second. It emits very bright pulses of electromagnetic radiation from gamma rays on down to low energy radio waves. It's one of the brightest sources of high energy photons in the sky. The inner portion of the Crab Nebula has been shown to continue to expand, driven by the persistent pulsar wind.

From Wikipedia:
The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus.
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 3 degrees in diameter (about 6 times the diameter, and 36 times the area, of the full Moon). While previous distance estimates have ranged from 1200 to 5800light-years, a recent determination of 2400 light-years is based on direct astrometric measurements.The distance estimates affect also the estimates of size and age.

The Crab Nebula is a supernova remnant and pulsar wind nebula in the constellation of Taurus.
It exploded just about 1000 years ago and is well recorded at the time. It is located 6 523 light years from the earth. Photographed from Spain (TelescopeLive) with a Officina Stellare 700 RC telescope
Aperture: 700 mm
Focal Length: 5600 mm

Sh2-157, also known as the Lobster Claw Nebula, is a bright emission nebula in the constellation Cassiopeia. It lies just south of the better-known Bubble Nebula (NGC 7635). The Lobster Claw Nebula is approximately 11050 light years (3390 parsecs) from the Earth. The predominantly yellow part of the nebula is a very large H II region that is ring-shaped by the stellar wind of several giant stars, including the bright and very young Wolf-Rayed star WR 57. The small bright region at the left and up of center of the image is Lyn's Bright Nebula 537 (LBN537 or Sharpless 157a). The blue colored regions at the right part of the image mainly consist of highly ionized oxygen (OIII) and other gases. The small open star cluster NGC 7510 is located at the bottom right part.

This Is a Narrow band shot of Thors helmet using two filter's Ha Red colour and O3 Blue colour to get the colour photo with the B/W camera. A lot of detail has come out of using the filters as well. Slowly coming to terms with the world of filters one of the drawbacks I am not able to rotate the filter wheel without upsetting the balance of the mount. the shot needed to be rotated a few degrees to the right to square up the wings on the helmet.
As it was just two filters I took 110 shot with each filter to make up this shot Combined in the Pallet of Ha O3 O3 to get the colours you see here much like the pure colour shot from before.

Herbig–Haro objects are small patches of nebulosity associated with newly born stars, and are formed when narrow jets of gas ejected by young stars collide with clouds of gas and dust nearby at speeds of several hundred kilometres per second.
The Pelican Nebula, IC 5070, has perhaps the most famous of these, HH 555.

New Messier object captured! M101. I was planning to do 4 hours on this target, but my wife fell asleep in the trunk of the car after 2 hours so I decided to cut it short 😂
My main goal was to have NGC 5474 in the same frame. This dwarf galaxy is tearing the arms of M101, which is one of the reasons why the Pinwheel Galaxy is not symmetrical.
I made a video of the entire capture, you can see it at: www.youtube.com/watch?v=KvxSCWAiZpY

Containing around 500,000 stars M3 (Messier 3) can be found in the constellation of Canes Venatici. Given it's distance of 34,000 light years away, surprisingly you should be able to pick out M3 with a pair of 10x50 binoculars from say a bortle 6 or 7 sky.

This is a total re-process from the ground up of the data captured earlier this month. The previous version had some issues, including a set of out of date flats which I had forgotten to refresh after changing focuser.
I also discovered the gamma settings on my iMac screen were much too high, making the blacks too deep, I was compensating by processing the background too light.

Shot this image of the M81 and M82 galaxy region with the goal of simultaneously capturing the Integrated Flux Nebula (IFN), something I've never done before. The IFN is an interesting and extremely faint subject that lies within our own galaxy. It is a type of reflection nebula, however it's illumination is not provided by nearby stars that is typical of reflection nebula. Rather, the IFN gains it's eerie glow from the total integrated flux of all the stars in the Milky Way! In short, our whole galaxy is the illumination source.
PixInsight's background extraction tools make pulling out the IFN surprisingly easy. Shooing at f/2.8 certainty helps too. This is just over 4hrs of exposure (52x300s) with unmodified Canon 6D and SharpStar 150HNT. To capture the equivalent amount of photon data with my 80mm refractor, this would have taken over 20hrs! Sky quality is approximately Bortle 3/4 at my location.

This is only a partial shot of IC 1805, the Heart Nebula, because the scope I took this with has a very narrow fields of view and the Heart Nebula is a very large object. So large it covers an area about four times that of the diameter of the full moon.
This is the result of 642 ten second images processed in PixInsight, NIK collection plugin for Photoshop, Topaz sharpening, and ProDigital Software's Star Spikes 4. I actually took 695 images but by the time the Weighted Batch Preprocessing of PixInsight was finished 53 of those had been rejected.
This nebula gets its name from its heart shape ... the top of which you can see the start of on the left side of the photo. A Google search will show you what the full image looks like.
The Nebula is located about 7500 light years away in the Perseus Arm of the Galaxy in the constellation Cassiopeia ... the group of stars that looks like a W in the sky.

M16 Like you may have never see it before. I have to confess I know where the Eagle( its so small you would miss it) is but as a whole I see a sleeping face with closed Eyes and what looks like a beard. I even asked my wife to come look she did not even get past the door "there is a sleeping face, you can see the hair and the beard" and I did not say a word.
This is only possible With Carlos Taylor Smallrig getting to feel like its home. I do think we all get 100% dominated by longer focal lengths we do lose sight of the leaves on the tree . This is in part why I will not forget to use my nikon lens to bring to life the whole not just the macro with a 10".

Close up to the Markarian's chain centred on the most estrange galaxy there, estrange in my opinion, of course.
Virgo cluster is a large cluster of galaxies due that, on this frame also appears other three NGC objects, other three IC and more than 30 galaxies from the PGC catalogue, please check the annotated version here:
It was necessary a long integration of more than 33 hours to show all this details.
On the right down side is noticeable the glow generated by the M86 galaxy that does not appear on the frame.

A Via Láctea, também conhecida como Via Látea, é uma galáxia espiral da qual o Sistema Solar faz parte. Vista da Terra, aparece como uma faixa brilhante e difusa que circunda toda a esfera celeste, recortada por nuvens moleculares que lhe conferem um intrincado aspecto irregular e recortado. Sua visibilidade é severamente comprometida pela poluição luminosa. Com poucas exceções, todos os objetos visíveis a olho nu pertencem a essa galáxia.[1]
Esta imagem é um close-up da região central de nossa galáxia. A nuvem escura mais pronunciada ao centro é conhecida como Nebulosa do Cachimbo. O objeto acima, o mais brilhante na imagem é o planeta dos anéis, Saturno que no momento da foto está localizado próximo à constelação do Serpentário (ou Ofiúco) e do Escorpião.
A imagem contém uma exposição total de 01h18m (26 subs), ISO 800, f/3.2 e foi registrada na zona rural de Campo Belo - MG em 06 de julho de 2016.

The Milk Way is a spiral galaxy that contains our solar system. Earth view, it appears as a bright and diffuse band that circles the entire celestial sphere, cut by molecular clouds that give it an intricate and irregular appearance. Your visibility is very compromised by light pollution. The most of visible objects naked eye belong to this galaxy. [1]
This image is a close-up of central region of our galaxy. The great dark cloud in center is known as Pipe Nebula. The object above, the most bright is planet of rings, Saturn that at moment of this image is located between Ophiucus and Scorpion constellations.
The image has total exposure of 01h18m (26 subs), ISO 800, f/3.2 and was registered in rural zone of Campo Belo - MG - Brazil at July 6th 2016.

Comet C/2022 E3 (ZTF)
The result of 30+ hours of "pushing the outside of the envelope" in PixInsight image processing. See the 3.5 hour time-lapse animation here: flic.kr/p/2ofokk7
C/2022 E3 (ZTF) is a non-periodic comet from the Oort cloud. It reached perihelion (1.11 AU from the Sun) on 01/12 for the first time in 50,000 years. Since its orbit has changed, the comet will either return in many millions of years or be ejected into interstellar space. On 01/24, the comet clearly displayed an ion tail, dust tail, and rare anti-tail as Earth passed through its orbital plane. The green glow in the coma is the emission of diatomic carbon. It passed 0.28 AU from Earth on 02/01.
On the morning of 01/20, I took a huge gamble and tried to shoot this comet with my new Tamron 70-200mm f/2.8 lens. It was a massive sacrifice to sleep 3 hours, wake up at 02:00 EST, set up/troubleshoot the previously untested rig, shoot until dawn, pack everything up, and leave for a long, exhausting work day. After stacking the images later that day, I was extremely disappointed with the result.
The otherwise fantastic lens suffers from internal reflections that are impossible to correct or remove. I spent days desperately trying to salvage the data with new calibration frames, different focus distances, etc., but I realized it was no use. From what I can tell it seems to be a pupil ghost (www.cloudynights.com/topic/536295-flat-not-correcting-cen...) caused by the glass elements and/or reflective rings inside, and there is no solution. I would have discovered the issue if I had tested it before. It was an excruciating lesson to learn.
Somehow, I was lucky enough to get another clear morning on 01/24. This time, I switched back to my trusted and proven deep-sky telescope. I woke up at 01:00 (4 hours of sleep), set everything up to start shooting around 03:00, packed up at dawn, and left for another long, painful day at work. Comet image processing was another mountain to climb, but I figured out a good workflow (influenced by Adam Block's technique: youtu.be/TaEwvC1lzKM) after 10 days of experimenting. The hard work has finally paid off and I'm super proud of this result!!
