I've accidentally found that the comet C/2018 N2 (ASASSN) was in some old and low quality data from the Andromeda Galaxy. What a great surprise! The comet is towards the bottom of the left side of the image.
Technical Details:
20 x 60 sec frames taken under suburban skies on November 2, 2019. Canon 550D at ISO 800, Samyang 135mm f/2. Tracked with a Star Adventurer Mini bundle. More details at AstroBin.
The heart of the Heart nebula revisited using the "natural palette" with special attention to the dark nebulas there.
It a complete rework of a previous image made on SHOrgb.
A total of 57 hours of integration and a lot of intermediate version on the process.
Still I think that I could obtain more details, but this will be next year (maybe :P ).

The Crescent Nebula (also known as NGC 6888, Caldwell 27, Sharpless 105) is an emission nebula in the constellation Cygnus, about 5000 light-years away from Earth. It was discovered by William Herschel in 1792. It is formed by the fast stellar wind from the Wolf-Rayet star WR 136 (HD 192163) colliding with and energizing the slower moving wind ejected by the star when it became a red giant around 250,000 to 400,000 years ago. The result of the collision is a shell and two shock waves, one moving outward and one moving inward. The inward moving shock wave heats the stellar wind to X-ray-emitting temperatures. [WIKI]

The Great Orion Nebula (Messier 42). We all know it. It’s one of the first targets we point our telescope or camera at before stumbling down the ridiculous rabbit hole that is astrophotography.
One of my main goals in astsophtoogrpahy has been to meticulously create the most detailed and deep image of the Orion Nebula I could manage. A perfect challenging in astrophotography, in my opinion, as Orion is both a delightful and easy target for beginners, and as advanced a target as we might like for revisiting in years to come. Over the past three years or so I’ve accumulated some 150 hours of data on Orion, scattered amidst assorted experiments and attempts in editing (which, up until now, I’ve never finished). Over the past four months I’ve collected the images for this rendition, and spent an embarrassing amount of time learning and experimenting with new (to me) post-processing approaches to arrive at this result. I’m sincerely delighted to share this labor of love with everyone.
Constrictive feedback and discussion are absolutely welcome.

Post-Processing
Source data includes two nights of long and short exposures captured with my Celestron RASA-8 and ZWO ASI2600MC Pro, and numerous nights captured with my Takahashi FSQ-106EDX4 and ZWO ASI2600MM Pro with Astronomik UV/IR L2 and Deep Sky RGB filters. With the Takahashi I captured short and long exposures in luminance and color, along with a separate 4-panel mosaic in LRGB (binned color) which I used for stars and fine detail in highlights. I discarded sub-par data from sessions liberally. A master luminance image was created with data combined from both telescopes (blended into RASA data for the larger field of view, which was a point of challenge). A master color image was created with the RASA data, which contributed color for nebulae and background. And the four-panel mosaic was prepared and processed separately, ultimately contributing detail in highlights and the stars in the final rendition. And just because, why not—I’ve gone this far—I used my best subset of 5s exposures captured in Hα, last year, for luminance on the Trapezium. (The original is more than 16000 pixels across, and I went out of my way to present fine detail so a large print could end up on my wall, allowing me to appreciate details up close, returning me to these fun and stupidly cold nights whenever I like.) Starless versions were sent out to Adobe Photoshop for final combination and blending. Some normal PixInsight steps, like HDR combination, also ended up being handled, in part, in Adobe Photoshop. PixInsight was used during this process for features such as Local Histogram Equalization.
It’s challenging to outline post-processing details on this one because the workflow ended up looking like the stereotypical insane person’s wall cataloging a crime scene investigation, but I’m delighted to answer any questions someone may have.

Another M82 :D
More that 20 hours of integration time. Specially dificult to display the fine details but it was easy to use only one telescope to capture all data.
Messier 82 is a starburst galaxy approximately 12 million light-years away in the constellation Ursa Major. A member of the M81 Group, it is about five times more luminous than the Milky Way and has a center one hundred times more luminous.

Another nice object from the amazing Sharpless catalog.
Close to 80 hours of integration time and really surprised by the blue bubble that appears in the middle (not the bright blue triangle, the big blue subtle bubble on top of that) .
As usual on my latest pictures, I used this "natural" palette that I really like so much.
The process was long and hard and the acquisition also due to the weather in my observatory's region.
This object was never something prioritari on my desk but I am really happy with the results, even with the hard work to process all this data.

Due to some troubles with the filter wheel it was not possible to do a deeper picture with this rig.
It's only 28 hours (latest objects on my list are about 60 hours each) but seems enough integration to provide good details on these Ha clouds.
It's a nice object that I revisited after more than two years, with new equipment, techniques and personal tastes.... I like to see my evolution

Another new image captured with this "not so much expensive" setup: Canon 200mm, Openastrotracker and ASI1600.
It's not easy to operate this mount on a remote site, but they are so fast preparing new versions and they are improving the software a lot. The community is so active and the drivers are evolving so fast.
At the end is a long exposure of 8 hours using a 2.8 aperture. Not an easy process due this nebulae is more dark and sutil than others tha I know.
The dark nebula Barnard 22 and the tiny flame-shaped reflection nebula IC 2087 are both part of the Taurus Molecular Cloud, which in turn contains many complex organic compounds in its extensive dusty nebula.

Preliminary result of one of my favourites.
I have to double the total exposure time with longer subs for a smoother background and to enhance the weaker parts of the nebula.

Probably the last picture with this setup, the last one with the ASI1600M / ASI183M.
I am upgrading my set up to QHY268M / QHY294M and also from the Riccardi reducer to TS-Optics RC 0.8x. (more info here)
It's a long process, to many changes.
But here is my Sunflower version.
It's an integration time of a little more than 24 hours.
From that version in 2017 astrob.in/292513/D/ to the current one, a lot of things happen.
It's a difficult object to me despite that I saw a good evolution over the years.
Always was like a defocus image, on this last picture I do all my best to correct that.
This is my last try with that focal
Now I changed my cameras but I am not sure if this change could produce better results. Maybe will check next year.
The distance to this Glaxy M63, based upon the luminosity-distance measurement is 29,300,000 light-years. Meaning that the light of the stars on this galaxy needs more than 29 million years to arrive to my camera.....
It's interesting how many other galaxies appear on the field.
Only with the PGC Catalog you could see another 7 but including the SDSS catalog up to mag. 19..... another 216 galaxies are annotated (it's full of galaxies, not stars!!)

LDN 1235 (or Lynds Catalog of Dark Nebulae n° 1235) is a dark/absorption nebula in the constellation Cepheus. It is composed by interstellar dust that is so dense that it obscures the visible wavelengths of light from objects behind it, such as the Horse Head Nebula or the Cone Nebula. It also blocks light from background stars.
Lynds Catalog of Dark Nebula is an updated version of the original version of the Lynds’ Catalog of Dark Nebulae that was published in 1962.
The data was acquired by my friend Démoniak's Alexkid using his ASKAR 400 in August 2021 from Ardèche in France (bortle 4). Two CMOS were used to capture this faint object:

In this image Comet C/2020 R4 (ATLAS) cruises by the Whale Galaxy NGC 4631 and the Hockey Stick Galaxies NGC 4656 & 4657 from our perspective here on Earth. This image was captured at Grand Mesa Observatory and processed by Terry Hancock and Tom Masterson.
Using two telescope systems last week this image was captured over two nights, 5/5 and 5/6. The first night, Wednesday 5/5 we used System 1 which has a Takahashi 130 telescope capturing images with the monochrome QHY 600 and System 4 where a Takahashi E180 telescope is used and images are captured on a QHY410 color camera. On Thursday night 5/6 only System 1 was used, on this night we focused on capturing more data to get a better background image of the galaxies since by this time Comet C/2020 R4 had moved out of this field of view.
Total Integration Time 7.75 hours
Both systems are available to subscribe to or request data from at Grand Mesa Observatory. If you would like to know more, please visit www.grandmesaobservatory.com/equipment-rentals.

This was just a quick 2 hours of data that I grabbed on a whim, as my actual target was too close to the moon to gather any useful data.
Quite happy with this process, even though, again, this was just a quick effort I smashed together at 1 AM when frankly I really should have been in bed ready for work at 7 AM.
This is my first attempt at an HDR image, so be kind.
10-sec subs for the core and 180-sec for the DSO.
All comments welcome.
Thanks

APOD: 2021 October 29, Haunting the Cepheus Flare
Imaged by me at Negev Desert during two nights this summer.
These cosmic clouds in Cepheus have blossomed 1,300 light-years away. Located near center of this field, the Iris Nebula, NGC 7023 is not the only nebula to evoke the imagery of flowers, though. Within the Iris itself, dusty nebular material surrounds a hot, young star. The dominant color of the brighter reflection nebula is blue, characteristic of dust grains reflecting starlight. Central filaments of the reflection nebula glow with a faint reddish photo luminescence as some dust grains effectively convert the star's invisible ultraviolet radiation to visible red light. Infrared observations indicate that this nebula contains complex carbon molecules known as PAHs. The pretty blue petals of the Iris Nebula span about six light-years.
The dusty ghosts in the right side of this field are close to the edge of the Cepheus Flare molecular cloud complex. Over two light-years across and brighter than the other spooky chimeras, VdB 141 or Sh2-136 is also known as the Ghost Nebula, seen at toward the bottom of the featured image. Within the reflection nebula are the telltale signs of dense cores collapsing in the early stages of star formation. A protostar can be seen forming at the lower right end of the nebula. The V-shaped projection is one side of the bipolar outflow induced by the protostar's rotating accretion disk. Light from the protostar itself can be seen feebly glowing at the vertex of the V. The opposite bipolar outflow exiting the opposite side of the nebula can just be glimpsed to the left of the bright yellow star above the nebula.

NGC 6357 The lobster nebula
After 3 months of constant cloud cover / rain in Melbourne Australia, I finally managed to gather enough data to process this wonderful celestial object.
This is an SHO image with RGB stars. This is a crop of the wide filed image I took with my 430mm refractor as I found it more interesting to look at it this way.
There are some wonderfull details in the middle of this nebula with what looks like a Koala reaching out for a star. Everyone I showed this image to seems to find a different animal in there... snakes, crabs, lobster of course!
This nebula is on the faint side with Ha and Sii being the predominant emission and Oiii being highly concentrated in the middle of the nebula, shown by the blue hue in this image.
NGC 6357, The lobster Nebula also know as War and Peace Nebula is a diffuse nebula located in the constellation of Scorpius. It includes an open cluster Pismis 24 made out of massive stars, the biggest one approaching 300 solar masses!

The Tulip Nebula (Sharpless 101) is an emission nebula in Cygnus.
It lies at an approximate distance of 6,000 light years from Earth and has a linear diameter of about 70 light years.
It's apparent magnitude is 9.0 and it occupies an area of 16 x 9 arc minutes of apparent sky.
I used HSO palette with RGB stars. More than 33 hours of integration time, selecting only the best frames of the total valid frames captured (80%).
All c&c will be appreciated.

The comet was setting towards West. Its altitude was very low, especially during the end of imaging. Thus, due to atmospheric refraction, bent star trails are apparent at the lower left corner of the image. Since this is the result of a comet integration with no rejection in PixInsight, several meteors trails and cosmic ray hits are visible. With a fast-evolving comet tail, one hour of integration may have dispersed the fine details of the comet's ion gas (blue) and dust (green) tails.
There is a gap at the middle of the star trails due to a brief pause during the imaging session.

C/2020 M3 (ATLAS) makes for a temporary fourth green ‘star’ in the constellation Orion’s belt in this image comprising of 47 x 2 minute and 29 x 15 second exposures taken from Grand Mesa Observatory on 11/11/2020.
While you’ll need a decent pair of binoculars from a dark location to see Comet C/2020 M3 with your eye, in photographs it shows up quite nicely as it photobombs the constellation Orion. Discovered over this past summer by the ATLAS telescope system, C/2020 M3 is at its closest approach to Earth today, 11/14 at about 33 million miles away.
The data used in this setup “System 2C” is available from Grand Mesa Observatory’s legacy datatbase

I've imaged the Heart Nebula before with my FLT91 and my Redcat 51, so I wanted to get closer and see the difference in detail with my FLT132. My previous project was to image the Fish Head Nebula up close (see flic.kr/p/2qg6dbf) , so I decided to move the scope a little bit and image the Heart Nebula as a follow up.
In my personal opinion, this area of space consisting of the Heart, Soul and Fish Head nebulae, is one of the most beautiful and rewarding to image. I hope you like it too.
I used my FLT132 with the Flat8 0.72x reducer, ZWO ASI2600MC pro with the Antlia ALP-T 5nm Ha & Oiii narrowband. I managed to get almost 24 hours integration time and I'm pleased with the outcome.
I used PixInsight to pre/post process as well as final touches with Affinity Photo 2.

==== From Wikipedia =====
The Heart Nebula is an emission nebula, 7500 light years away from Earth and located in the Perseus Arm of the Galaxy in the constellation Cassiopeia. It was discovered by William Herschel on 3 November 1787. It displays glowing ionized hydrogen gas and darker dust lanes.
Dust Cloud 183 (top left) was first cataloged by Dr. Lynds in 1962 (1) and has recently been calculated to be 105 parsecs away (2). It is part of a complex of cold, dense, and starless dust and molecular clouds which also includes LDN 134 (lower right).
I wanted to frame the photo in a different way and found that it looked quite dramatic flipped into portrait mode. Frames were taken south of Grafton in a Bortle 4 location by Lake Ontario.

Descrição:
A Nebulosa de Eta Carinae é uma das jóias do céu do
hemisfério Sul. São muitos as zonas interessantes a se destacar: Keyhole, bright-rimmed globules, dark globules, Dust Pillars, Star cluster Trumpler 14 e Trumpler 16, Mystical Mountain e os Stellar Jets. É uma das maiores nebulosas difusas do céu e cerca de quatro vezes maior que a Grande Nebulosa de Orion. Está a cerca de 7500 anos-luz da via láctea. A região central da imagem nos brinda com brilhantes filamentos bem como nuvens escuras de poeira cósmica.
There are a lot of firsts for me in this image. First deep sky image from a dark sky (SQM 21.3 on this night), first image with new camera (SBIG STF-8300C), first time automating entire imaging run (via ACP), and first time combining images from multiple nights. It's also the first time I've done the majority of processing in PixInsight. So much to learn in this hobby!
