First Light Image using a new QHY600M Water Cooled photographic version monochrome CMOS camera that we are beta testing for QHYCCD, a review of this awesome new camera is forthcoming soon.
Quote from QHYCCD: The water cooled version provides an additional 10C ambient over the standard version and an important feature is the water cooled version has zero vibration because there is no fan inside the camera.

The Jellyfish Nebula (IC 443) is a supernova remnant located in the constellation Gemini.
It is situated about 5,000 light-years away from Earth and spans across an area of about 50 light-years in diameter.
The nebula got its name because of its tentacle-like structures, which resemble those of a jellyfish.
These structures are formed from the shockwaves created by the explosion of a massive star, which occurred about 30,000 years ago.
The explosion produced a blast wave that is still expanding outward, colliding with the surrounding interstellar gas and dust and creating the striking filamentary structure we see today.
The Jellyfish Nebula emits light across a broad range of wavelengths, from radio waves to X-rays.
The filaments of gas and dust are primarily made up of hydrogen, but also contain other elements such as oxygen and sulfur.
The nebula also contains a pulsar, a highly magnetized, rotating neutron star that emits a beam of electromagnetic radiation.
Observations of the Jellyfish Nebula have provided important insights into the processes that shape and influence the interstellar medium. It is a popular target for astronomers studying supernova remnants and their interactions with the surrounding interstellar material.

In this image taken on the early morning of Dec. 3, 2021, at Grand Mesa Observatory, Comet C/2021 A1 (Leonard) is seen moving past Globular Cluster M3 in our night sky when a meteor streaked across this scene, lighting up the image and creating one of the most spectacular shots we have had the privilege of working with. It was captured and processed by Terry Hancock and Tom Masterson using a QHY367 Pro C one shot color CMOS and a Takahashi E180 Astrograph, GMO’s System 4a telescope grandmesaobservatory.com/equipment
After processing this image, I looked up what the color of the meteor means for its makeup and found that yellow/orange meteors most likely are made up of sulfur and iron. The strands of vapor moving off the meteor tail are so mesmerizing. What a treat it was to capture this image! Comet C/2021 A1 (Leonard) will continue to brighten in our night sky this month but will become difficult to image or observe as it approaches the sun in our sky. It flips around and becomes an evening comet later this month, which will hopefully make it easier for more people to observe. Fingers crossed it brightens past expectations. Currently it’s a binocular-observable comet, but it may become naked eye visible in the next couple nights if it’s not already.

Imaged using the Celestron C14 Edge HD telescope in dome 3 at Los Coloraos observatory in Gorafe, Spain.
A really popular image for astro photographers . It is bright full of interesting features making it a target for all focal lengths.
I have imaged this galaxy many times with smaller telescopes, but had the opportunity to image at 3900mm using the C14. 14 hours of data over three nights in May 2024. Really happy with the results.

M 3 is found in the constellation Canes Venatici and is one of the three brightest globular clusters in the northern sky.
Discovered by Charles Messier in 1764 and later by William Herschel in 1784.
I chose this cluster because when the moon is bright (99%), you need a bright image to be able see through the Moon glow in the sky. We have been having really poor weather in southern Spain and this was a small opportunity to take an image in between the clouds. Unfortunately the humidity was at 100% for the entire session making for slightly blurred stars, but I though it would be a challenge to see what I could make of just 2.5 hours of data under extreme conditions.
A single night of imaging in June 2023 from my home in Gérgal, Spain.

Presenting an M31 Andromeda Galaxy “beginner equipment” side-project. I wanted to capture a deep space object with what is representative of relatively “beginner” equipment and modest exposure times as a sort of “you don’t need to spend heaps of money to make a good image” demonstration. And Andromeda seems like the perfect target for this sort of thing. Something I can share when people argue a basic camera can’t make a nice image, or get caught up feeling as though spending thousands of dollars is the right solution to solve frustrations they are encountering learning this challenging hobby.
As Ed Ting quipped (paraphrased), “You end up spending a lot of money to find out you didn’t need to spend a lot of money.”
Or maybe it’s mainly a “for better or for worse” reminder that experience, process, and (especially) post-processing knowledge and software are valuable parts of the formula. Expensive equipment does not offer an escape from this. Not to say the right sort of equipment (e.g. an interchangeable lens camera with a decent sensor and a tracking mount) doesn’t play a vital role in what is possible.
Hopefully this is helpful.
And in the spirit of this goal, I also spent some time documenting, in detail, the post-processing steps and thought process behind the edits involved. For this I used PixInsight and Adobe Photoshop.

NGC 2467 The Skulls and Crossbones Nebula.
This is my first capturing this object. It is quite high in the sky from Melbourne at the moment and I got some pretty good data.
It is a beautiful part of the sky and the star field in particular is quite stunning in my opinion.
Processing:
I have now made 2 versions of this image
The first image is a traditional SHO combination with RGB stars where the green hue has been shifted to the Reds and the distinct blue hue for the oxygen shows in the middle of the nebula.
The second image in a rather rare colour combination SHS. I have not seen this object processed with this colour palette before but I really like what it bring to the image with the red, orange, gold and purple tones combined with the RGB stars here which was achieved by doing an SHS combination (Oiii only in lumiance layer combined with Ha) targeting the green in the image and shifting it to the reds. Then I shifted the magenta in the neutrals to achieve the palette you see here.

Description:
NGC 2467 is a large and bright emission nebula located in the constellation Puppis. It is also known as the "Skull and Crossbones Nebula" due to its distinctive shape (which I'm still struggling to see the be honest) , which appears to resemble a skull and crossbones.
The nebula is situated about 12,000 light-years away from Earth and spans an area of approximately 150 light-years across.
The nebula is thought to have been formed by the intense radiation and stellar winds from massive hot stars located in its central region. These stars have ionized the surrounding gas and dust, causing it to emit light in the visible and infrared portions of the spectrum.

NGC 6357, also known as the Lobster Nebula or War and Peace Nebula, is a diffuse nebula located approximately 5,500 light-years away from Earth in the constellation Scorpius. The nebula spans about 400 light-years across and is a rich region of star formation, containing many young, massive stars.
This nebula is particularly known for hosting a cluster of massive stars called Pismis 24. Some of the stars within Pismis 24 are amongst the most massive stars known.
Within the complex structure of this nebula, a distinct feature has been observed that resembles a koala bear. "The Cosmic Koala," formation adds an intriguing visual element to the nebula. The resemblance to a koala may be attributed to pareidolia, a psychological phenomenon where familiar shapes or patterns are perceived in random or unrelated objects. Some well-known examples of nebulae exhibiting pareidolia includes The Horsehead Nebula, The Witch Head Nebula, The Cat's Eye Nebula and The Elephant's Trunk Nebula to name a few!
If you can’t see the Koala go to this link below and all will be revealed :)

The Cosmic Koala and the Lobster Nebula together offer a fascinating example of how our minds seek to make connections between the vast universe and the world as we know it. While the focus of scientific inquiry remains on understanding the physical processes at work within the nebula, this unique feature serves as an interesting point of engagement for those like me interested in astronomy, art and the wonders of the cosmos.

After several months of working, finally the new set up is up and running.
I changed ASI1600 -> QHY268 on RC10 and AS183 -> QHY294 on TS107 and all that involved!! A lot, a lot of effort as you really know
This is the first good image after all that changes, calibrations and preparations.
It's a classic, super-photographed target, really good to compare with previous results, like this from 2017:
4 years it's a lot of time to learn more PIX techniques, upgrade the telescope, filters and cameras and of course, change the palette that I am using.
I prefer this framing and thanks to all that experience, hardware changes and more than 67 hours of integration, it's more detailed and more deep.
It's amazing how this kind of small details appear
I hope you like it, more images on the pipeline!!

NGC 2736, also known as the Pencil Nebula, is a fascinating object located in the southern constellation of Vela, approximately 800 light-years away from Earth.
It is a part of the larger Vela Supernova Remnant, which was formed by a massive stellar explosion that occurred around 11,000 years ago.
The Pencil Nebula is a type of nebula called a filamentary or linear nebula, it is about 5 light-years long, but its width is only about 0.3 light-years.
The Pencil Nebula is primarily composed of ionized oxygen gas but there are also a fair amount of hydrogen (Red) and Sulfur (purple) present.
The origin of the Pencil Nebula is not entirely clear. Some astronomers believe it was formed by a shock wave from the supernova explosion that created the Vela Supernova Remnant, while others suggest that it was formed by a separate, more recent supernova.
Processing:
The colour combination was a HSO but with Sulfur added to the magenta rather than the green to keep a natural colour look.
The Askar had a nice focal to capture this object with and allowed me to present the object with a lot more resolution compared to my hi resolution mosaic of the entire vela supernova

This image is a collection of data captured over 2 seasons using a QHY600M Monochrome CMOS from Grand Mesa Observatory's system 1 the Takahashi FSQ 130 (available on our subscriptions) Captured over a total of 13 nights in October 2020 and February 2022, this final rendering comprises of 1,706 individual frames for a total acquisition time of over 48 hours.
The Flaming Star Nebula also known as IC405 and Caldwell 31, lying at a distance of approximately 1500 light years from us in the constellation Auriga this object is a combination of emission and reflection Nebulae. Visible towards the bottom left in this image is IC410/Sharpless 236 otherwise known as The Tadpoles lying at a much further distance of 12,000 light years, this faint Emission Nebula is energized by the neighboring Star Cluster NGC1893.
In this Hubble Palette version the H-Alpha is mapped to green, SII is mapped to red and OIII is mapped to the blue channel. Stars were removed using StarXTerminator then I used the naturally colored stars from the broadband image. While the colors in this image are not the true colors, the narrowband filters used in the making of this Hubble Palette image reveal much more of the hidden gasses not visible in a broadband image.

7000-7500 light-years distant in the constellation of Cassiopeia lie the emission nebulae colloquially known as the Heart and The Soul Nebulae. The gasses (mostly hydrogen) that comprise the nebulae are being ionized by the stars within the region and as a result, the gasses glow, much like a neon sign.
The pressures exerted upon the material by the stars nearby are causing the material to become compressed. When enough of the gas becomes highly compacted, it triggers the birth of new stars. In effect, this is a beautiful snapshot of a multimillion-year process of an enormous cloud of dust and gas transforming itself into new stars.

This is the real First light with this new rig:
An Openastrotech mount with Canon 200 2.8 lens and ASI1600MM-C.
With new Baader Planetarium Ha 6.5nm CMOS-optimized.
I would like to do many things, add Sii and Oiii data and with this FOV a lot of new objects are on the list....
It's really interesting how much signal could be captured only with 10 hours of integration time (f/3.5!!)
This nebula, also called Sh2-240 is about 3.000 light years away and it was discovered in 1952.
It's a really big object, in the next picture you could see a simulation if you shoot the moon with this equipment.
astro.carballada.com/simeis-147-spaghetti-nebula-rgb-ha/
I am really excited searching the next target!!
IC 4604 and friends. The Ro Ophiuchi Nebula
This is officially my first RGB picture without using narrowband filters. Taken from a bortle 2 zone during the new moon in the little town of Tolmie in country Victoria, Australia. This is about 15h of data across 2 panels. My FOV does not allow me to capture the whole of the Rho Ophiuchi complex, so this is the best I could do with the time I had.
Funny enough I did not combine the luminance channel with this data as I found that it washed out of a lot of the details in the blue channel, detail that just was not really visible in the luminance channel, no matter how hard I have tried to pull it out, so this is a straight RGB picture

The incandescence of the Eagle Nebula is laced with intricate dark lanes, globules, and huge clouds of dust which shroud ongoing star formation from direct view. The most prominent dark structures are the so-called “Pillars of Creation”, three long fingers of gas and dark dust nearly ten light years long. The Pillars are a field laboratory for the study of star formation and have been examined intensely by astronomers at visible, infrared, and ultraviolet wavelengths. Within the Pillars are much smaller, warmer, and denser regions called evaporating gaseous globules (EGGs), some of which contain just a few solar masses. The EGGs are ground zero for star formation, though it’s difficult to catch these new stars in the act of igniting because they remain obscured by cloaks of dark dust. EGGs located near bright stars are elongated by winds of light and charged particles into what look like schools of celestial tadpoles.
The stars within the Eagle Nebula appear to be in an intermediate state. Stars within the Pillars and other dusty regions remain obscured, while a cluster of some 400 new stars clearly appears in a more transparent section of the nebula. The largest of these stars has a mass some 80 times that of our Sun and the luminosity of perhaps a million Suns. The cluster formed just 2 to 5 million years ago. The nebula itself is only slightly older.
The light we see from the Eagle Nebula and its associated stars left some 7,000 years ago, but some astronomers suspect the Pillars of Creation may have already been obliterated when a massive young star within the nebula detonated as a supernova. The Spitzer Space Telescope detected evidence of a patch of hot gas near the Pillars which may have been caused by such an event about 8,000 years ago.

Here is my photograph of Comet C/2022 E3 (ZTF) aka “The Green Comet” which I captured on January 30, 2023—a soul-crushinginly cold night with temperatures around -25°C—in the Skull Valley desert, Utah, United States. With so many cloudy nights this winter, I thought I would miss this one. But circumstance gave me one good opportunity as long as I was willing to brave the cold. Did you know that touching metal after hours outside at these temperatures enables it to somehow “burn”?
This image was created using 175 separate 30-second exposures (longer and the comet actually streaks relative to the stars due to its movement), combining of the comet image separately from the stars, and then re-combining the two. As a bonus, you can multiple galaxies in the image.
Comet C/2022 E3 (ZTF), called the “green comet” in various news coverage, is visible in the night sky right now, although less impressive than 2020’s Comet Neowise.
ZTF will be hard to see under moonlight with heavy light pollution, but easier to see with no moon and binoculars. With little light pollution it is much easier to see. (Apparently it was quite striking to see when my mom checked it out under her crazy-dark Wyoming skies!) This comet’s “near pass”—the closest point in its orbit to the earth—was on February 2nd. While still visible, it is now traveling farther away from earth, growing fainter day-by-day. If it survives its journey, it will return again in around 50,000 years. Something for the kiddos to look forward to!
Comet C/2022 E3 (ZTF), at the time these photos were captured, featured two prominent ‘tails’:
The blue-tinted tail (extending frame right) is the ion tail, which is created by ultraviolet radiation ejecting electrons off particles in the coma (a cloud of gases surrounding the comet’s nucleus). The appearance of the ion tail can change rapidly (e.g. even between short exposures) due to interplay with and fluctuation of the solar wind (a continuous flow of charged particles ejected from the sun).
The warmer, fainter, larger “tail” is the dust tail, formed by solar radiation vaporizing volatile compounds in the comet, which stream out and carry dust with them. This reflects sunlight directly.
How do you end up with the name “Comet C/2022 E3 (ZTF)”? Breaking it down, “C” represents a non-periodic comet: it takes more than 200 years to orbit the sun. It was discovered in 2022. “E3” represents the time period of discovery, with “E” represents the fifth half-month of the year, and “3” representing the third comet discovered in that half-month. “ZTF” stands for who discovered it! In this case, the Zwicky Transient Facility, which is a wide-field sky astronomical survey running through the Samuel Oschin Telescope at the Palomar Observatory in California. What about 2020’s “NEOWISE”? In that case, it was discovered by NASA’s Near-Earth Object Wide-field Infrared Survey Explorer.
Why are articles calling this “The Green Comet”? Mainly, I expect, because very cool or very terrifying things love to have a name of some sort in media coverage, and “The Green Comet” got to stick. “ZTF” is not so catchy, to be fair. Comets typically present with a clear blue-green glow around the nucleus. It is rather prominent on this comet, relative to other signal, but not a unique characteristic of this comet. So why this color? Sources frequently cite that this color comes from Cyanogen (CN) in the comet, but this is not correct. As best I can determine, the most likely explained by a combination of “Swan Bands” of Carbon (C2) emissions—which is to say, some blending of prominent light emissions is responsible for the color we observe. This was probably discussed in early interviews and got to stick.

Thanks to the good seeing last night, it was possible to prepare this mosaic.
It was made using the Classic Cassegrain 8" from my remote observatory and a IMX174 camera.
It could be one of the latest images with the QHY5III174 at native f12 2400mm because I will change it soon to fire at f19 3800 again.
Also at the same time I will use a new ASI183M at f12 to obtain better spectrophotography.

In the middle of the huge period with closed/rainy weather (which has been going on for more than 3 weeks) in the region where I live, there was a beautiful opening on the night of the 10th to the 11th, when I took the opportunity to make some planetary records. When Mars's turn came, unfortunately the time closed again, right at the beginning, making it impossible to capture more frames.

Sh2-117 North America Nebula (NGC 7000) and Pelican Nebula (IC 5070) and Surrounding Region
Pictured here is a region known as Sh2-117 (roughly the area of brightest intensity), a complex star-forming region comprised of bright emission nebulae and patches of dust lanes which obscure stars and light includes. Featuring prominently, among other interesting structures, is the North America Nebula (NGC 7000), named for its resemblance to the land comprising the United States, and the Pelican Nebula (IC 5070), named for resembling, well, a pelican. Sh2-117 is estimated to span some 140 light years across with the North America Nebula, on its own, spanning some 90 light years end-to-end.
Departing our little blue marble, it would take us about 1,800 light years to arrive at the Pelican or 2,200 light years to arrive at the North America Nebula.
(A “light year” is the distance light would travel given a year of transit. For context, in a vacuum light travels at 670,616,629 mph or 1,079,252,849 km/h. These numbers are stupid-hard to comprehend. Traveling 2,680 miles across the United States, at this speed, we would arrive in 14.39 milliseconds.)
I’m guessing it is obvious which structure is the North America Nebula, but the “Pelican” may not be so clear. It is the prominent structure “above right” from the North America Nebula, and makes more sense with the view rotated 90°. Or, click below for a preview.
If we could see these nebulae clearly with the naked eye, we would also be in for a treat. In terms of apparent “size” in the sky from our point of view, this region is massive. The moon is large enough (if it were eclipsing these nebulae from our view) to rather effectively plug the “Great Lakes” void in the North America Nebula. But it is hard to see much of this region with the naked eye, beyond cloudiness under dark skies, in part due to the most intense light from this region emitting in Hydrogen-alpha at a red-spectrum wavelength our eyes aren’t sensitive to. But you can see more in binoculars, and a consumer camera can start to “see” clear structure in seconds.
This photo is comprised of 17 hours of images captured across four nights at my home in Salt Lake City, Utah. A narrowband filter was used to isolate wavelengths imaged on a color camera and blended into a false-color palette (a form of presenting narrowband in color, similar to how Hubble images are presented) where the blues represent dominant Oxygen III regions and the reds represent regions rich in Hydrogen-alpha regions. I used a RedCat 51 telescope and a Sony A7R IV, mounted on an iOptron CEM-40EC equatorial mount. Editing was done in PixInsight and Adobe Photoshop. Synthetic channels were derived from the color data to create the false color palette. For more information about equipment and detailed editing notes, see below on AstroBin.

Always I planned to adquiere as much data as possible of the center of this object.
Now after 80 hours of integration time I am really happy with the results.
A lot of details on LBN673 and a powerful Dobashi 3919 just on the center.
All these details belong to the main object Sh2-199 called Soul Nebula, mainly is a large emission nebula in the constellation Cassiopeia approximately 7,500 light years distance.
My main project is to add more teselas to this mosaic, I will continue next year...

My first image for some time due to problems with my mount in February, which has since been repaired (new control boards) and also the lack of darkness over the summer here in the UK.
SH2-119, sometimes called the Clamshell Nebula, is a close neighbour of the North America Nebula and Cygnus wall but not often imaged. Processed as SHO with channel and colour balance achieved using Bill Blanshan's new NarrowBandNormalisation script in PI which makes the job of matching channels so much easier.

Finally a really first light of this new Takahashi Epsilon-160ED
I am so excited!!! This scope is good!!! really fast at f/3.3 with 530mm.
Usually I take bigger integration time (around 70 hours), at this speed I spend 'only' 28hours, half of the regular time to obtain these nice results.
Also, this scope fits really well with the modern CMOS camera with such small pixels.
Description from waid-observatory.com :
Sh2-224 is a very faint supernova remnant located approximately 14,700 lightyears distant in the constellation Auriga. This unusual celestial object is also designated VRO 42.05.01 and has been the object of considerable research using both ground based and space based telescopes including the ROSAT and the Dominion Radio Astronomy Observatory. The nebula created by the supernova explosion is composed of two visual parts. It is postulated the supernova explosion created a bubble like structure. (Visible in the 'lower right' of the image.) As the shockwave from the explosion progressed into a very low density region of the interstellar medium, a "wing" component was expelled. (Visible in the 'upper left' right of the image.)
Supernova explosions are the end stage of the natural life cycle of very large stars. Such events are responsible for the distribution of heavy elements into the interstellar medium where they are incorporated in the birth of new star systems. Without this phenomenon, planets, such as the Earth along with life as we know it, would not be possible.

Finally I take enough data to process this object like I want.
Like my last previous works I try to obtain the maximum detail with a very long integration, more than 73 hours this time.
It was processed using the natural palette, assigning Sii to an ultrared tone.

This is my first attempt using the new Sigma Art 135mm f1.8 lens and ASI294MM-C camera.
The field of view (FOV) was amazing, covering a wide angle of 5º
Although I require further practice to fully explore the capabilities of this new optic, I am delighted with the initial results of this test.
LBN 1228 is a region of gas and dust that is illuminated by the intense radiation from nearby young, hot stars.
It is also sometimes referred to as Sharpless 2-132 or Sh2-132.LBN 552, on the other hand, is also an emission nebula located in the same region of the sky as LBN 1228, and is sometimes referred to as Sharpless 2-138 or Sh2-138.
It is thought to be approximately 4,000 light-years away from Earth and is estimated to be around 30 light-years across.
Like LBN 1228, LBN 552 is a region of gas and dust that is illuminated by nearby young, hot stars.
t is also known for its intricate filaments of gas and dust, which create a beautiful and unique appearance.
