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.

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.

Here's an interesting duo located near the border of Cepheus and Cygnus. The open cluster NGC 6939 is actually about 5000 light years away, a part of our own Milky Way galaxy. Beside it, but 22 million light years further away is the galaxy NGC 6946. Since the galaxy lies close to the plane of the Milky Way, it is highly obscured by the interstellar dust and material that lies in the foreground. I also learned that it is often called the Fireworks Galaxy because of the number of supernova observed within it.
The image was taken through a Stellarvue SVS130 through red, green, and blue filters (90 minutes each), and enhanced with Hydrogen-alpha (also 90 minutes). Processed in MaximDL, PixInsight, and Photoshop, and upsampled 2x.

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!
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

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.

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)

M 13 is 145 light-years in diameter and composed of between 300,000, to more than half a million gravitationally bound stars in the constellation of Hercules.
It’s a spectacular star cluster to see in a telescope with its super bright core of hot blue stars.
The 1974 Arecibo message, which contained encoded information about the human race, DNA, atomic numbers, Earth's position and other information, was beamed from the Arecibo Observatory radio telescope towards Messier 13 as an experiment in contacting potential extraterrestrial civilisations in the cluster. M13 was chosen because it was a large, relatively close star cluster that was available at the time. The cluster will move through space during the transit time but opinions differ as to whether or not the cluster will be in a position to receive the message by the time that the message arrives.

My second attempt at this target. Previously imaged from my home in Spain using my Celestron C11 Edge HD in Bortle 4 skies, this image was taken using the Celestron C14 Edge HD telescope at the remote complex of Complejo Astronómico, Los Coloraos, Gorafe, Spain, Bortle class 3. Taken during the Full Moon and 98% Moon over two nights!
Also look out for the small galaxy in the top right of image designated as IC 4617. It is located 553 million light-years from our solar system and has an estimated diameter of 115,000 thousand light-years making it slightly larger than our own Milky Way.

I continued my personal exploration of Cygnus in narrow band.
I like so much the results of this emission nebula near Deneb, about near 5.000 light years of distance to us.
Probably I will zoom to this nice Sharpless object with my RC10 at some point on the future.

Taken with Nikon Coolpix P950 with ND16 filter. Yellow sun was taken from video frame. The enlarged insert is a stack of 5 raw images (16mb resolution), resampled 3x in PixInsight and aligned to minimize turbulent induced distortion and noise. Focal length was 2000mm (83x) normal view.
This sunspot group is so large that it visually rivals Carrington's famous sunspot of 1859: spaceweather.com/archive.php?view=1&day=08&month=...

The Soul Nebula, IC1848, is an emission nebula located in the constellation Cassiopeia. IC1848 is the eastern neighbour of IC1805 (the Heart Nebula: flic.kr/p/2p1mT9W), and the two are often referred to as "Heart and Soul". More information on this nebula can be found here: www.constellation-guide.com/soul-nebula/
I took this image with my William Optics FLT91 + F68III 1.0x flattener, my ZWO ASI2600MC Pro colour camera, Optolong L-Ultimate 3nm dual-band filter (Ha, Oiii), ZWO AM5 mount with ASIAir Plus for almost 6 hours (in 3, 5 and 10 minutes exposures at -10C and 100 gain). Then stacked with ASIStudio (ASIDeepStack) and processed with PixInsight and Affinity Photo 2.
This is the SHO-Hubble palette look-alike version processed in PixInsight. This is an interesting approximate process as the image taken with a colour camera and Ha, Oiii dual-band filter only has HO and not Sulfur, so it’s never going to be as good as an image taken with a monochrome camera and SHO filters.
Please see the HOO version here: flic.kr/p/2p136yR
I hope you like it.

The Mirrors were aligned and this was the test target. This was shot over three nights one interrupted by rain that was not suppose to happen , the friday night and saturday night as total shots.
I had to put faith in Nina to work on friday and focus did not fail as it was set off at 9pm by itself as I would be way out of town. Deep in the sand dunes of lancelin . As I was so tired on Saturday I did the very same as it worked well on friday night.

We each have our reasons why we are here and why to "enjoy" this difficult way of taking photos. As a kid my father had the "time life" book on space one of the illustrations was the Horse head, I was always taken as a kid there was a Horse out in space. I all ways knew where it was as Orion on the norther side of the equator was very easy to spot much like here on the southern side.
The traditional view with a one shot colour camera RGB red background. This shot is SII as Red Ha as Green O3 as blue but RGB stars. As the Ha is the dominant element its usually very green but I have only kept a hint of Green.
Glad to see this in real life I have never see the Horses beard before. Look closely you can see the shadow cast by the Nebula Back lit from behind. I have to work on getting the focuser set up and filter wheel balanced to be able to rotate the whole train to get the better view. The Filter wheel is very heavy so if you move out from inline the whole rig is thrown out of balance very badly. Thinking as Only MacGyver can.

The Elephant's Trunk nebula is a concentration of interstellar gas and dust in the star cluster IC 1396 – an ionized gas region located in the constellation Cepheus about 2,400 light years away from Earth. The piece of the nebula shown above is the dark, dense globule IC 1396A; it is commonly called the Elephant's Trunk nebula because of its appearance at visible light wavelengths, where there is a dark patch with a bright, sinuous rim. The bright rim is the surface of the dense cloud that is being illuminated and ionized by a very bright, massive star that is just to the west of IC 1396A. The entire IC 1396 region is ionized by the massive star, except for dense globules that can protect themselves from the star's harsh ultraviolet rays.(Explore Scientific ED127, ZWO ASI2600MM, ASIAIR, EAF, EFW, AM5, Antlia SHO 3nm, Pixinsight, Photoshop).
The Beehive Cluster (also known as Praesepe (Latin for "manger", "cot" or "crib"), M44, NGC 2632, or Cr 189), is an open cluster in the constellation Cancer. One of the nearest open clusters to Earth, it contains a larger population of stars than other nearby bright open clusters holding around 1,000 stars. Under dark skies, the Beehive Cluster looks like a small nebulous object to the naked eye, and has been known since ancient times. Classical astronomer Ptolemy described it as a "nebulous mass in the breast of Cancer". It was among the first objects that Galileo studied with his telescope. (ref: Wikipedia)

This should be the Lectern Microphone Nebula …..or. The Menacing Tadpole Nebula. About the composition: Framing a nearly invisible object presents problems. Sure 5 minute exposures reveal most detail required to frame the primary target but only after processing are subtle structural features made obvious. As all imagers know…..the sky soon disagrees with my task requiring clarity and two more nights of imaging won’t be for a long while so I can’t overwhelm the existing data with new data that better displays the tower/pillar formation’s base. Oh come on….just a little pan a little …..but yay anyway!
