I've added another two and a half hours of data to this image and it still needs more. I pushed this image quite a bit, maybe to much, to show some of the detail and color that came up with the added data.
I would like to add more, we'll have to see what the weather is going to be like before the moon is in the sky again.

The Cocoon Nebula, IC5146, is an emission and reflection nebula in the constellation Cygnus and lies some 3300 light years away. The central star that lights the reflection nebula was formed roughly 100000 years ago. The Cocoon is an area of active star formation in the emission nebula. The nebula is further surrounded by a dark nebula, Barnard 168, which appears as a dark lane extending away from the Cocoon.

M106, also known as NGC4258, UGC7353 and PGC39600.
"Messier 106 is an intermediate spiral galaxy in the constellation Canes Venatici. It was discovered by Pierre Méchain in 1781. M106 is at a distance of about 22 to 25 million light-years away from Earth. M106 contains an active nucleus classified as a Type 2 Seyfert, and the presence of a central supermassive black hole has been demonstrated from radio-wavelength observations of the rotation of a disk of molecular gas orbiting within the inner light-year around the black hole."

An updated image using both PixInsight and Photoshop for post-processing. A dramatic improvement over my original post.
Caldwell 32 (aka NGC 4631 and the Whale Galaxy) is a barred spiral galaxy. It is seen edge-on and its profile resembles that of a whale. The galaxy is estimated to be 30 million lys from Earth and is found in the constellation Canes Venatici. The dwarf elliptical galaxy, NGC 4627 is seen above NGC 4631 in this image.
This is the second galaxy image I have taken using my Celestron C9.25 SCT. I am no longer using the Celestron dew heater ring for dew management. Instead, I am using a dew shield and dew heater strip. When using the dew heater ring the stars had distracting star spikes. I did collimate the scope before taking this image. This significantly improved the roundness of the stars.

Here’s a shot of Messier 33 (NGC 598) is commonly known as the Triangulum Galaxy. Barely visible to the naked eye, this nearby spiral is the third-largest galaxy in the Local Group, after the nearby Andromeda Galaxy (M31) and our own Milky Way. This data was shot last September with the RASA 8 in my light polluted backyard using a LP filter to block out the street lamps nearby.
I have been using DBE in PixInsight and have been getting much better results with brighter targets. I also isolated the red channel using @astrobackyard ‘s method of noise reduction. Thanks Trevor.

I was given Carlos small rig Sharpstar 61EDPH II，ED Glass，APO，F5.9，Refractors，Aperture 61mm and a Primaluce SESTO SENSO Focuser which has an overall focal length of 275mm but depending which camera I put on it I can get 1100mm or 412 mm out of the same set up. I dont have short cables most of mine are 1.8m long i had three piled up on top but I was able to make two shorter ones for this rig.
To get balance I had to add a weight to the camera as I had to use my guide scope which is bigger and more front heavier than Carlos one. As the Computer is under the front I also had to add a small wire to tie up the front to make sure it was all stable.

The Crescent and Soap bubble are two very different nebulae in the heart of the constellation Cygnus. The pair lie in a dense field of gas and dust.
The Crescent nebula is an emission nebula that lies around 5000 ly away in the constellation Cygnus. The nebula is formed by stellar wind from the central Wolf-Rayet star, a star that has consumed its hydrogen fuel and currently burns helium and other heavier elements. The stellar wind ejected amounts to a solar mass every 10k years. This stellar wind collided with the slower moving stellar wind which was released during its earlier red giant phase. During this collision, two shock waves resulted; one moving away from the star and one toward the star. The shock wave moving toward the star compressed the remaining gas, making a strong X-ray source. It's thought that the WR star will explode as a supernova in 100k years.
The Soap Bubble Nebula is a planetary nebula about 4.3 arc-min across and was only recently discovered by D. Jurasevich in 2007/2008. It lies some 4000 light-years away and spans a diameter of 5 light years. As a planetary nebula, it's the expanding shell of a ionized gas thrown from the host star by strong stellar winds as it undergoes it's transition from red giant phase. These gasses become ionized by the remaining red giant core, making them visible to us.

I managed to get three targets in this shot thanks to the little Asker FRA400 scope and the 533 sensor. Located in the constellation of Cassiopeia.
All data was gathered at www.astronomycentre.org.uk/
They are: NGC 7635 the Bubble Nebula. Discovered by William Herschel in 1787 it lies about 7,100 light years away and spans about 7 light years across.
NGC 7538 Northern Lagoon Nebula is the bright patch to the lower left. This is a stelar nursery some 9,000 light years away. It is actively forming proto stars, many of which are 40 times the mass of our Sun.
M52 open star cluster.
Also given the NGC 7654 tag.
Discovered by Charles Messier in September 1774. Sometimes called The Scorpion cluster lies about 5,000 light years away and is the only one of these 3 targets that can be picked up in a pair of binoculars.

This is a target that is shot out of city lights and pollution, But what the heck just go for it I have never shied away from a challenge. This a reflection nebula the light comes from the bright blue stars in the nebula.
This is version 3 one and two this morning I just did not like so sat down this afternoon to try and make it look more real not a cartoon. Armed with a Full glass of red wine I thought what did I not like how can I simply make it better this is one hour later taking the steps thinking and slowly.
This is one I have always wanted to do but knew its not quite what you should do in the city better out in the black of country. Enjoy the Blue Horse

Wide field on the Heart and Soul Nebulae, 5 hours and 45 minutes of HSO integration with Red Cat 51 Petzval Telescope, ASI6200mm pro 61-megapixel full-frame Mono camera, mount
Paramount MX 6, are 69 shots of which in Ha 17x300 seconds, in OIII 12x300 seconds and in SII 40x300 seconds, processing with Pixinsight and Photoshop.All data and shots were acquired with Sadr Astro Observatory. IC 1805 (also known as the Heart Nebula or by the abbreviation W4) is a nebula spread in association with an open cluster, visible in the constellation Cassiopeia, towards the border with the Giraffe.It can be detected about 6 degrees southeast of the star ε Cassiopeiae, but it can also be detected starting from the Perseus Double Cluster and moving about 4-5 degrees in a north-northeast direction; it pairs with another vast nebula, known as IC 1848. To be able to locate it, you need a telescope with a large diameter, not so much because of its size, since the nebula is quite large, but because of its weakness. A long-exposure photo or a CCD camera, on the other hand, reveals the object with some ease. The entire complex of nebulae visible in this area is circumpolar from most regions of the northern hemisphere; The best months for its observation are from October to April. It is a very large HII region, whose distance is estimated at 7500 light years from us; Its main feature is the presence of two large, apparently empty areas, of different sizes, which make the nebula similar to a "heart". Inside there is a system of small, loosely concentrated open clusters, responsible for the ionization of the nebula. The most notable of these is Melotte 15, which contains some stars about 50 times more massive than the Sun, plus others smaller and a microquasar ejected millions of years ago.
This and nearby IC 1848 form a large nebulous complex known as the W3/W4/W5 or "Heart and Soul" complex; the "heart" is IC 1805, while the "soul" is represented by IC 1848. IC 1848 (also known as the Soul Nebula, Embryo Nebula or by the abbreviation W5 for Westerhout 5) is a diffuse nebula associated with an open cluster of young and hot stars of great mass, visible in the constellation Cassiopeia, towards the border with the Giraffe. This is one of the areas where star formation is most active. The nebula can be detected about 8 degrees southeast of the star ε Cassiopeiae, but it can also be identified starting from the Perseus Double Cluster and moving about 5 degrees in a northeasterly direction; it pairs with another vast nebula, known as IC 1805. To be able to locate it, you need a telescope with a large diameter, not so much because of its size, since the nebula is quite large, but because of its weakness. A long-exposure photo or a CCD camera, on the other hand, reveals the object with some ease. The entire complex of nebulae visible in this area is circumpolar from most regions of the northern hemisphere; The best months for its observation are from October to April. It is a very large H II region, whose distance is estimated at 7600 light years from us; its gas is illuminated by the stars of some clusters and associations of nearby stars, among which Cr 33 and Cr 34 stand out, two very large but unconcentrated open clusters, formed by blue giant stars born from the gas of the nebula. The light is then re-emitted by the nebula in the red color typical of H-alpha hydrogen emission lines. Star formation is very active within the nebula.
Comet C/2023 A3 (Tsuchinshan-ATLAS) is in the evening sky! And it’s the brightest comet in 27 years, the brightest since Hale-Bopp in 1997. The closest approach to Earth was on 12 October 2024. The comet does not approach close to the giant planets of the Solar System. The orbit is weakly bound to the Sun before entering the planetary region of the Solar System. Due to planetary perturbations, the outbound orbit will have a smaller eccentricity than the inbound orbit. So the orbital period and aphelion distance become much shorter. The weakly hyperbolic trajectory may or may not result in the comet being ejected from the Solar System.
This view of the Lagoon Nebula (M8) was captured from my backyard using a Celestron Origin telescope in alt-az mode with the raw images processed in Pixinsight.
The ionized gases of nebula are represented here using the Hubble Palette for color images. Sulphur II, Hydrogen Alpha & Oxygen III produce light in the red, red-orange and green wavelengths respectively. Here they are spread more fully across the visible spectrum for color contrast purposes to Red,Green & Blue. The variety of intermediate colors indicate the presence of multiple gases, but also the broadening of the very narrow bands (7nm wide) of captured data into, say, the 350 nm wide visible spectrum we think of from Red to Violet.
My Focuser on the main telescope would not calibrate so I had to send it away to get looked at. So I have turned the Clock back to my old school days when I first started out in Astro.
Nikon 300mm D F4 AF-S come from the 2000s days . There is no auto focus on this rig its all manual focus at the start of the Night and tape lens. In the lens defence for its age even though I checked focus each night it never moved. So this setup is just nikon lens, Filter draw With Optolong LeNhance filter inside( for light pollution) and the QHY183C colour camera.
This is 29 hour's worth of data in the hope the lens worked out well. To say that I am over the moon with the end result is an understatement who said its complicated. I had thought of more shots but 29 hours is plenty as I have not heard back I will find another target to try.

A couple of days ago I was practicing with my Sbig ST-10XME camera the SkyX software and my mount MYT
My target was the Leo Triplet with an integration time of one hour (L filter)
This camera made for astrophotography is very sensitive and every time I use it I get surprised of what can be achieved with it.
Here is the crop of the main three galaxies .
It is a quick process, my goal was only practice.
Decided to go back to this and give it a reprocess with the newest PixInsight updates and methods. This is a mosaic of the MW Core Region I did 3 years ago, shot with a ZWO ASI2600mc Pro and Voigtlander 110mm APO lens. It is a 20 panel mosaic with each panel consisting of 45-60 minutes of data. The original processing had a lot of problems, it was extremely difficult to manage all the data, gradients, star size differences, color changes from panel to panel, etc. As a result there were a lot of stitching artifacts, gradient/color artifacts, and destructive star processing methods used to get the final version I posted.
This new version uses several new tools within PI to maintain star quality, image color, overall detail, and noise management. I also tried as best as I could to reduce stitching artifacts. There's still some problems, mostly the blues around the core area that aren't entirely accurate and some "haziness" for lack of a better word. I'll keep working on it in the short term while our spring weather rollercoaster continues and we can't get any imaging done anyways.
This is a "10k" version of the image in only jpg quality, I had originally drizzle integrated the files, but the final stitch size was too large for any software to properly save/process the file. So I resampled by 50%, then downsampled another 50% for uploading purposes. The non-"internet" version is almost 20k pixels on the long edge!
A beautiful area of emission and reflection nebula in Monoceros, featuring, surrounding NGC2264:
- The Christmas Tree cluster
- The Fox Fur nebula
- The Monkey Face nebula
- Cone nebula
This image has been built with data from 28/12/14, 10/12/17 and 16/11/18. The total integration time is 15 hours.
Camera: QHY23 mono CCD
Scope: Takahashi E130D
Focal length: 430mm f/3.3
Exposures:
H-alpha (49 x 600s bin1)
O-iii (8 x 600s bin2)
S-ii (8 x 600s bin2)
Red, Green, Blue (18 x 300s bin2) per filter
The data files were calibrated (bias, dark, flat) and stacked in PixInsight using drizzle alignment/stacking and Windsorized-Sigma-Clipping with upper and lower range rejection as well as large-scale structure clipping. This latter parameter allowed the different data sets taken over 3 years to be merged without too many seams and missing areas of data where the camera/scope orientation was different.
The image was then built in Photoshop with the following layers:
Red channel: Red+H-alpha+Sii
Green channel: Green + Oiii
Blue channel: Blue + Oiii
A narrowband Hubble Palette image was built with Sii-Ha-Oiii layers to merge with the final colour image.
H-alpha, Sii and Oiii were also blended to form a master Luminosity layer.
Star colours were retained by blending a low-enhanced colour layer of the stars only on to the final image.
All data was taken from Cumbria (UK) on 3 nights between 2014 and 2018.
Stack of 6x 20" exposures at F4, 400ISO and 14mm focal length.
Taken near Lake Ellesmere on Saturday 26th October, processed with PixInsight for stacking and BlurXterminator goodness, and DxO PhotoLab for final tweaks.
This is a shot I have been wanting to take of the whole area not just the two main Nebulas Lagoon & Triffid. Up the top is the chinese dragon nebula Look at the black line through it you can see the dragon.
I love the view of the surrounding area and all the very dark lanes. to me I see a teenage Ninja turtle for those old enough to remember. This is a two panel panorama shot between clouds and rain. I can say this has lived up to every thing I knew about the area. M8 M20 & NGC 6559

I then experimented on PixInsight with the BlurX/NoiseX/StarX suite to try improve this stack while balancing uneven brightness from the horizon just below the bottom of the frame and the zenith at the top.

A large star forming region called the Soul Nebula (IC 1898) can be found in the direction of the constellation Cassiopeia, who Greek mythology credits as the vain wife of a King who long ago ruled lands surrounding the upper Nile river. The Soul Nebula houses several open clusters of stars, a large radio source known as W5, and huge evacuated bubbles formed by the winds of young massive stars. Located about 6,500 light years away, the Soul Nebula spans about 100 light years and is usually imaged next to its celestial neighbor the Heart Nebula (IC 1805).

This image is about comparing Photoshop processing (my customary tool) of lunar data to PixInsight processing. This image, processed in PixInsight, is rendered from the same data as the Crater Copernicus image processed in Photoshop and posted on 2022-08-22.
My impression of this image is that although it reveals more detail than the one originally posted, there seems to be some remaining softness that can be improved by better seeing and use of a UV-IR cutt filter
After registration and stacking in Autostakkert, all follow on processing to this image was in PixInsight instead of Photoshop.
PixInsight processes used:
ChannelExtraction to pull out separate RGB channel images
LinearFit to normalize channel levels
ColorCombination to reassemble into a single RGB image
UnsharpMask for sharpening
CurvesTransformation for RGB, saturation and CIE c* component stretches
Simeis 147, also known as the Spaghetti Nebula (SH2-240), is a supernova remnant in the Milky Way straddling the border between the constellations Auriga and Taurus. Discovered in 1952 at the Crimean Astrophysical Observatory using a 25-inch Schmidt-Cassegrain telescope, it is difficult to observe due to its extremely low brightness. It is believed that after its stellar explosion a rapidly spinning neutron star known as pulsar PSR J0538+2817 was left behind in the nebula core, emitting a strong radio signal.

Hydrogen, the "StarStuff" the Universe is made of.
A widefield HaRGB mosaic of the Sagittarius Trio - M8, M20 and NGC 6559 (a dense region of stars, interstellar dust clouds, and dark nebulae, reflection nebulae and emission nebulae).
About this image:
Imaged in 7nm Hydrogen-Alpha Narrowband (concentrating mainly on the Hydrogen that emits in the red part of the spectrum), and combined with a little old RGB DSLR data.
About Hydrogen in Emission nebulae:
Emission nebulae are glowing clouds of interstellar gas which have been excited by some nearby energy source, usually a very hot star. The red light seen in this picture is glowing Hydrogen captured in the Hydrogen-Alpha (Hα) Infrared wavelength of light at 656nm.
Image Acquisition:
Sequence Generator Pro with the Mosaic and Framing Wizard.
Plate Solving:
Astrometry.net ANSVR Solver via SGP.
Processing:
Pre-Processing and Linear workflow in PixInsight,
and finished in Photoshop.

NGC 6820 is a small reflection nebula near the open cluster NGC 6823 in Vulpecula. The reflection nebula and cluster are embedded in a large faint emission nebula called Sh 2-86. The whole area of nebulosity is often referred to as NGC 6820.
Open star cluster NGC 6823 is about 50 light years across and lies about 6000 light years away. The center of the cluster formed about two million years ago and is dominated in brightness by a host of bright young blue stars. Outer parts of the cluster contain even younger stars. It forms the core of the Vulpecula OB1 stellar association. (Description credits: Wikipedia)
