Another nice wintertime deep space object to photograph, the Rosette Nebula in Monoceros. It's advertised as 5200 light years from Earth, and the star cluster within it is estimated to be only 5 million years old. It's still just a baby!

February 3, 2025, backyard, Tallahassee, Florida. Bortle 7 suburban sky. Seeing was good though transparency was average to poor with high altitude cirrus clouds passing from west to east. Guiding was poor because I was too lazy to do a proper polar alignment.
Many people see religious imagery in clouds, reflections, toast, and rust stains on the side of buildings, among many other things. In that vein, I call this image, "Laughing Jesus." Watch out for the holy spittle! I imagine that He just tricked Satan into pulling His finger.

Description:
The centre of our home galaxy, the Milky Way, lies in the constellation Sagittarius, in the middle of the prominent bulge of stars and nebulae in this view, made with a wide angle 35 mm lens. Numerous star clusters, dark foreground gas clouds, and pink hydrogen gas nebulae are strewn across the frame.
The centre of the Milky Way lies very low on the horizon as seen from the northern hemisphere. Astronomers travel to the south in order to see the magnificence of the Milky Way straight overhead in the months of May-August.

This was the first clear night in some weeks in Toronto. Yes it was very cold, but this was the day when I received my new Nikon Z7 mirrorless camera, and I just had to try it out on the Full Moon. Actually, the Moon was not yet quite full when I got the subframes from which this image was made; it would not reach its full phase for another 2 hours, 26 minutes. Also, the Moon was 5° south of the ecliptic, so we could look "over" the north limb (or edge) of the Moon's disk, and see some of the shadows inside the craters along the north (upper) limb that are apparent in this view.

Description:
The LMC is satellite galaxy of our own Milky Way that is part of the Local Group of galaxies, lies about 163,000 light years from us, and has a diameter of about 14,000 light years. Nearby is the smaller galaxy called the Small Magellanic Cloud (SMC).
To the unaided eye in a dark sky site the LMC is a large, faint glowing patch that appears detached from the band of the Milky Way.
From Wikipedia:
"Although both clouds have been easily visible for southern nighttime observers well back into prehistory, the first known written mention of the Large Magellanic Cloud was by the Persian astronomer `Abd al-Rahman al-Sufi Shirazi, (later known in Europe as "Azophi"), in his Book of Fixed Stars around 964 AD.
The next recorded observation was in 1503–4 by Amerigo Vespucci in a letter about his third voyage. In this letter he mentions "three Canopes [sic], two bright and one obscure"; "bright" refers to the two Magellanic Clouds, and "obscure" refers to the Coalsack.
Ferdinand Magellan sighted the LMC on his voyage in 1519, and his writings brought the LMC into common Western knowledge. The galaxy now bears his name.
Measurements with the Hubble Space Telescope, announced in 2006, suggest the Large and Small Magellanic Clouds may be moving too fast to be orbiting the Milky Way."
The Tarantula Nebula is a region of glowing hydrogen gas within the LMC. It is extremely luminous, so much so that if it were at the distance of the Orion Nebula it would cast shadows.

****************************************************************************
NGC 3718, also know as ARP 214, is a distorted spiral galaxy in the Constellation Ursa Major and is located about 59 Million Light Years away. Its distorted form is thought to be gravitational interaction with the other galaxy seen in this image - NGC 3729 - at some point in the distant past. These are all part of a group of galaxies known as the Ursa Major Cluster.
One interesting footnote - below NGC 3718 you can see a small grouping of elongated shapes, very close together. While not shown very well in this image, this is a small group 5 galaxies known as Hickson 56. These Galaxies are estimated to be about 400 Million Light Years away!
These galaxies are very far away and very small. The largest here only measure 2.9" x 2.4" in size. I mention this because I really don't have a scope that is setup for these very small galaxies. SO why did I chose this target? Well, part of me wanted to see what I could do with it. Another part is that this time of year the number of targets is a bit limited - especially what I can access due to the tree lines on my property.
This is the third and last image to come out of my 3 night imaging cycle starting on June 4th. While we had three clear nights, we also had some bands of thin clouds that came through and the overall sky transparency was far from great. The thin clouds are not enough to lose a guide star and disrupt your runs, but they can ruin the contrast on critical subframes. In this case, I had to remove roughly 1/3 of my subs and it reduced the number of Green frames I ended with to less than half what I had for the other channels.
When first processed this image - it looked pretty bad. So I went back to square one, and this time I spent a huge amount of time working on the image deconvolution step. Some people think of deconvolution as a "Sharpening" step. In fact it does something quite different. Working it the frequency domain, it attempt to restore lost information caused by the optics. This is very tricky to use properly and for my first year of astrophotography I could not get any good results out of this at all. Then I got some help from Gary Optiz and Dan Kutcha and I was able follow a "recipe" and get some small advantage to my images. This time though, I really dug into it - played around with every parameter and saw how it impacted the image. At the end of it all, I had finally figured out how to use it properly, and I had a version of the linear image that had more detail than I had before.
With this I went forward and processed the image doing the bulk of the work in Pixinsight, and then shifting to Photoshop for the last polishing phases. I also used Topaz Denoise AI, on a few trouble spots along the way.
In the end - I was happy with the final result - but I also knew that to get the results I really want here I need a few things: 1) a scope with more focal length and resolution 2) Clearer and more transparent skies. 3) and a lot more integration time.
Thanks for looking!

SH2-119 is an often overlooked nebula just east of the North American and Pelican nebula. It is quite a bit fainter, but also covered with masses of stars, which overwhelms the nebula itself. The large star at it’s centre is 68 A Cyg which resembles a pearl within the Clamshell.
Taken over four nights in August, comprising Sii, Ha and Oiii narrowband filters of 5 minute and 10 minute subframes totalling 10h hours, plus 30 minutes 30 second subs of RGB for the stars. A challenge to process, particularly with the mass of stars. I think this could really benefit with at least 12 to 15hrs total exposure but not much chance with the current run of cloudy weather. This particular SHO palette is from a quite complicated Pixelmath expression in Pixinsight that produces a reddy orange instead of yellow. Star reduction to reveal the nebula.

M31 with M32 lower middle and M110 upper right. This image was taken in light polluted skies with a colour deep sky camera and is a stack of just 20x2minutes subframes. I was experimenting with its settings to see what would work effectively on this target without the usual problem of over-exposing the central area. Normally with deep sky CCD cameras I need two or three hours of data to get a similar result.

Description:
The constellations Leo, Ursa Major and Canes Venatici, which are well seen in the northern hemisphere spring, are populated with many galaxies that can be seen in amateur telescopes, as long as the observer gets out of the light-polluted city and finds a dark rural sky.
Near the familiar star pattern of Leo (the Lion) are three bright galaxies that are favourite targets of amateur stargazers. M66 (lower left) is a spiral galaxy located about 31 million km from our Milky Way galaxy. It has loosely wound arms and prominent dust lanes, and recedes from us at the rate of ~700 km per second.
The nearby M65 (lower right) is another spiral galaxy that is a little fainter and 4 million km further away than M66.
Both of these galaxies were discovered by famed French astronomer and comet hunter Charles Messier on 1780 March 1 at the Paris Observatory.
The larger but fainter galaxy NGC 3628 (top centre, also called the "Hamburger Galaxy) is a spiral galaxy at the same distance (35 million km) as M65. Discovered by English astronomer William Herschel in 1786, this galaxy appears almost edge-on as seen from Earth, and has a very prominent dark dust lane along its outer edge.
Foreground stars to about 16th magnitude can be seen in this image.

Description:
On of the brightest patches in the northern section of our home galaxy, the Milky Way, lies in the constellations Aquila (the Eagle) and Scutum (the Shield). This starcloud contains many open clusters of stars, together with foreground globules of cold dark gas that are the incubators of new star formation.
One of the most prominent star clusters in this area of the sky is M11, the so-called "Wild Duck" cluster, which is a favourite observing target of amateur astronomers with modest telescopes. M11 is the small bright blob in the lower right quadrant in this image. This is a rich open cluster of stars that looks like a duck in flight. See en.wikipedia.org/wiki/Wild_Duck_Cluster for more information about M11.

Messier 3 (also known as M3 or NGC 5272) is a globular cluster found in the northern constellation of Canes Venatici. The image below was taken on April 23, 2016 from Weatherly, Pennsylvania using a Meade 12” LX-90 telescope, Canon 6D camera both mounted on a Celestron CGEM DX mount. Total exposure time was 3-minutes using 15-second subframes at ISO 5000.
M3 is one of the three brightest globular clusters in the Northern hemisphere (along with M13 and M5). I wonder what our night sky would look like if we were inside a globular cluster? I found an interesting little article here (www.astronomy.com/magazine/press-releases/2014/05/july-2014) worth reading. Imagine a sky with a thousand stars as bright as Sirius!

- The “S” stands for “Sport”/ “Sports” while the “L” meant “Leichts”/ “Light”. Some say “SL” stands for “Sehr Leicht”/ “Very Light”.
- During its first years the 190 SL was available as a sports-racing model with small perspex windscreen and spartan one-piece leather covered bucket seats and aluminum doors.
- The 190 SL was primarily intended for the US market; a lot of comfort, but little speed.
- Some owners leave the hardtop permanently on their cars, but an official Coupé was never produced.
- All SLs were assembled in Untertürkheim, Stuttgart - Germany.
- From the total of 25,881 units built, 5,245 remained in Germany, 20,636 units were exported, including 10,368 units to the United States.

Special:
- Austin-Healey was a British Sports Car maker founded in 1952 through a joint venture between the Austin division of the British Motor Corporation (BMC) and the Donald Healey Motor Company (Healey), a renowned automotive engineering and design firm. Leonard Lord represented BMC and Donald Healey his firm.
- BMC merged with Jaguar Cars in 1966 to form British Motor Holdings (BMH).
- Donald Healey left BMH in 1968 when it merged into British Leyland.
- Healey then joined Jensen Motors, which had been making bodies for the "big Healeys" since their inception in 1952, and became their chairman in 1972.
- Austin-Healey cars were produced until 1972 when the 20-year agreement between Healey and Austin came to an end.
- The Austin-Healey Sprite was designed by Donald Healey as a low-cost Sports Car and production began at MG's Abingdon factory in March of 1958. Later models were also assembled in Enfield, New South Wales and in Australia.
- A few months later, the new car was officially introduced in Monte Carlo, just prior to the Monte Carlo Rally.
- In the UK it's called "Frogeye", in the US "Bugeye" and in Germany "Froschauge".
- The headlights mounted on the top of hood were "lifted" because of U.S. Import legislations.
- Concealed flip-up headlamps were in the original drawings but high production costs canceled those plans.
- To build this little 2-door Roadster they used Austin, MG and Morris parts to keep the costs down.
- The two front chassis legs projecting forward from the passenger compartment mean the shell is not a full monocoque. The front sheet-metal assembly, including the bonnet (hood) and wings, was a one-piece unit, hinged from the back, that swung up to allow access to the engine compartment.
- The engine for example was also used in the Austin A35 and Morris Minor 1000 Series and the rack and pinion steering was derived from the Morris Minor 1000 Series and the front suspension from the Austin A35.
- It has no exterior door handles and no exterior boot lid (the back seats would need to be folded down to get access, incl. the spare tire).
- The entire front hood hinged upwards, allowing easy and convenient access to the engine.
- It was made at the MG works in Abingdon and sold for £669, so the intention of keeping the price low worked.
- By the quarter-elliptic rear springs, a simple self-supporting body and little weight, the Sprite is a rigid car to drive: But real fun to drive ☺☺!
- They are still very popular for club racing.

Nine years after the the TR7 had ceased production, another British manufacturer, Grinnall Specialist Cars modified existing TR7 and TR8 cars. TR7 cars were upgraded with TR8 subframes and dash. They then installed V8 engines (optionally bored to larger capacities), and other parts like suspension, gearbox and brakes from the Rover SD1. The front and rear wings were widened to match the SD1 axles and suspension. 350 convertible cars were produced, each with Grinnall badging
The Triumph TR7 is a sports car manufactured by BL (British Leyland) at Speke, Liverpool, Canley, Coventry and Solihull, West Midlands from September 1974 to October 1981. The car was launched in the United States in January 1975, with its UK home market debut in May 1976
Designed in house by Harris Mann, who also designed the Princess, it has a distinctive wedge shape, and with a swage line sweeping down from the rear to just behind the front wheel, it was advertised as . The Shape of Things to Come .The car has an overall length of 160 in (410 cm), width of 66 in (170 cm), wheelbase of 85 in (220 cm) and height of 49.5 in (126 cm). The coupé has a kerbside weight of 2,205 lb (1,000 kg).Because of proposed US legislation on roll-over protection at the time of its launch, the TR7 was not initially offered as a Convertible, In early 1979, Triumph belatedly introduced a convertible version, called the TR7 DHC (Drophead Coupe)
Power is provided by a 1,998 cc eight-valve four-cylinder engine that shares the same basic design as the Triumph Dolomite 1850 engine, albeit increased to 2 litres and fitted with larger carburettors, mounted in-line at the front of the car. Power is 105 bhp
For export to the US market, Triumph created a much more powerful Triumph TR8 model in 1977/78, which was a TR7 with a 135 bhp (101 kW) 3.5 L Rover V8 engine. While some genuine TR8 models stayed in Britain

The small galaxy NGC 5643, about 34 mill light years away in Lupus constellation. It's a Seyfert tipe galaxy. LRGB composite for 5 hours. GSO RC 30cms scope, camera STF8300/ AO-8, subframes of 12 min from my backyard observatory at La Colonia, Illapel, Chile. Not often imaged...
IC443 is a supernova remnant about 5000 light years distant. For this false colour image I captured light emitting from hydrogen, sulphur and oxygen ions and then combined in a HSO tone map i.e. hydrogen is red, sulphur is green and oxygen is blue. Throughout much of the jellyfish hydrogen and sulphur emissions are equally strong giving yellow, while oxygen is relatively weak and is only visible around the edges.
The image is an integration of 12 hours of H, 13 of O and 14 of S captured in 10 minute subframes on a QHY163M camera with Optolong filters, The telescope was a WO FLT110 with Flat4 and this was mounted on a Skywatcher AZ-EQ6. Imaging was managed by Sequence Generator Pro with PHD2 for guiding and all post-processing was carried out in PixInsight.

Description:
Visually with the unaided eye, or in binoculars or a telescope, the distinctively-shaped North America Nebula appears as a large but faint white cloud in the middle of our Milky Way galaxy. The digital camera sensor, however, reveals the red glow of ionized hydrogen gas.
This nebula is 1,600 light years distant from our solar system. Clouds of dark gas lie between us and the nebula, blocking the light behind and creating the apparent shape of the nebula.
For a wider angle view of this nebula - photographed with a telephoto lens 9 nights earlier - that also shows the adjacent Pelican Nebula - click here:

Special:
- The Plymouth automobile was introduced on July 7, 1928. It was the Chrysler Corporation's first entry in the low-priced field, which at the time was dominated by Chevrolet and Ford.
- The logo featured a rear view of the Mayflower ship which landed at Plymouth Rock, hence the name "Plymouth" as the brand.
- The origins of the first Plymouth can be traced back to the Maxwell automobile. When Walter Chrysler took over control of the trouble-ridden Maxwell-Chalmers car company in the early 1920's, he inherited the Maxwell as part of the package. After he used the company's facilities to help create and launch the Chrysler car in 1924, he decided to create a lower-priced companion car. So for 1926 the Maxwell was reworked and re-badged as a low-end Chrysler model. Then at the end of the decade this model was once again reworked and re-badged, this time to create the Plymouth.
- The word "fury" denotes a type of anger, inspired by the Furies, mythological creatures in Ancient Greek and Ancient Roman mythology.
- From 1960 the name Fury was no longer used for the original Sports Sedans, but for the most exclusive line Plymouth's. The successors of the original type Fury were called Sport Fury since then.
- The 1961 Fury V8 Series RP2-H, with a reskin “below-the-beltline” and its pinched aluminum grille, was available as this 2-door Convertible, as 2-door Hardtop (16,141 units built), as 4-door Hardtop (8,507 units built) and as 4-door Sedan (22,619 units built).
- This second generation mid-sized Fury’s (1960-1961), designed by Virgil Exner, were assembled in Detroit, Michigan (Lynch Road) and in Windsor, Ontario (Canada).

An ultra light 2 seat Coupe, debuting at the 1957 London Earls Court, Motor Show.
The Elite's most distinctive feature was its highly innovative fiberglass monocoque construction, in which a stressed-skin unibody replaced the previously separate chassis and body components. the Elite also used this glass-reinforced plastic material for the entire load-bearing structure of the car, though the front of the monocoque incorporated a steel subframe supporting the engine and front suspension, and there was a hoop at the windscreen for mounting door hinges and jacking the car up.
The first 250 bodies were produced by Maximar Mouldings at Pulborough, Sussex but production problems caused numerous early problems, until manufacture was handed over to Bristol Aeroplane Company

After stacking the subframes I was very surprised by these faint HII regions (unknown to me; perhaps someone can give me some information) at top of the coma and also under the near coma part of the tail (giving false red color to it).
Coma diameter is 37 ' and tail length about 1 degree.
