Description:
This view of the centre of our home galaxy - the Milky Way - lies in the familiar constellations Sagittarius (left side) and Scorpius (right side). This part of the cosmos is always very low in the sky as seen from the northern Hemisphere.
When I captured the ten subframes that comprise this image, the constellations Sagittarius and Scorpius were almost directly overhead. The dark sky of the Australian Outback makes for a dramatic, high-contrast view.
Here is the equipment used to make this image:

___________________________________________
Located just south of the end star of the Big Dipper in the constellation Ursa Major (The Great Bear) (but actually across the border in the constellation Canes Venatici - The Hunting Dogs) the Whirlpool galaxy is a favourite target of amateur astronomers, especially in the northern hemisphere spring and early summer.
M51, which has a black hole at its core, is about 35% of the size and mass of our own Milky Way galaxy. It was the first galaxy to be identified as spiral in structure. The two portions of this galaxy interact with each other; the smaller satellite portion is named NGC 5195. The distance to this galaxy is still quite uncertain; estimates are between 15 and 35 million light years. By contrast, the great Andromeda Galaxy lies a mere 3 million light years from us.

This is the first galaxy I have seriously put effort into. I used a Sony A7III camera mounted on a Celestron C14 EdgeHD telescope with a .7 focal reducer. I stacked 20 subframes and did some post processing in Lightroom.
Mu Cephei, officially named the Garnet Star, is a red supergiant star in the constellation Cepheus. It appears garnet red and is located at the edge of the IC 1396 (Elephant's trunk) nebula. Mu Cephei is more than 100,000 times brighter than the Sun. It is also one of the largest known stars with a radius around or over 1,000 times that of the sun, and were it placed in the Sun's position it would engulf the orbit of Mars and Jupiter. (Wikipedia)

M101 is in the constellation of Ursa Major, and is roughly 21 million light-years away. It is nearly 3 times as wide as our own Milky Way Galaxy and contains an estimated 1 trillion stars
I started this project in early April of this year, and due to weather just completed it last week. This is my first image of 2026 and my last was from Oct '25
It took this with an Orion ED102T & a QHY Minicam8. Shot through L-R-G-B filters(75- 3 minute subframes), for a total of 3h 45m. This was also blended with images from a 11" Celestron Edge with Hyperstar and a QHY268C for an additional 2h 26m(73-2 minute subframes)
Kind of sad that there has only been a handful of clear moonless nights since Oct of last year

Description:
As it revolves around the Sun in its stately 30-year orbit, the gas giant planet Saturn passes through each constellation of the zodiac in about two and half years. 2018 finds Saturn in the constellation Sagattarius (the Archer), set against the star clouds and nebulae that lie toward the centre of our Milky Way galaxy.
Saturn is the brightest object left of and below centre in this view. The massive red-pink Lagoon Nebula appears at lower right, with the smaller Trifid Nebula (with both blue and red components) above it. Many star clouds and tendrils of dark foreground gas can be seen throughout this region of the galaxy.
Right now Saturn shines at magnitude 0.0, and lies about 9 AU (astronomical units, the average distance between the Sun and Earth) from us. Light takes 1 hr 15 min to travel from Saturn to Earth. It is moving in retrograde motion (i.e., backwards, from east to west, or from left to right in this view), and will do so until mid-September, when it will come to a standstill and resume direct motion from west to east. At that time in September, Saturn will lie much closer to the Lagoon and Trifid nebulae.

449P
The car's 2,992 cc (182.6 cu in) twin-turbocharged V6 engine architecture is shared with the Ferrari 296 and its Group GT3 counterpart, the 296 GT3. However, instead of being mounted to the subframe as in the road-going vehicle, the engine is a fully stressed member in the 499P, and has had various modifications to accommodate its new role as a stress-bearing member. The 499P has semi-permanent all-wheel drive, with an electric motor situated at the front axle, providing 200 kW (272 PS; 268 hp) above 190 km/h (118 mph) (as stipulated by the regulations), and is connected to a bespoke 900 V battery pack, with the ability to be recharged by Ferrari's own Energy Recovery System (ERS)
This is my project for October 2017: Helix Nebula (NGC 7293) or: "The Eye of God". This is a preliminary version of this ongoing project, this one only without narrow band filters. 24 h total exposure time (180 sec for each subframe). Only data of the RGB camera with a L-pro filter.

The Crab Nebula, also known as Messier 1 or NGC 1952, is a famous astronomical object located in the constellation of Taurus. It is a supernova remnant, resulting from a massive stellar explosion that was observed by Chinese astronomers in the year 1054. The nebula is approximately 6,500 light-years away from Earth and spans about 10 light-years in diameter.
At the heart of the Crab Nebula lies a pulsar, which is a rapidly rotating neutron star. This pulsar, also known as the Crab Pulsar, is only about 6 miles in diameter, has a mass greater than the Sun and spins 30 times per second. Observations indicate that the Crab Nebula is expanding at a rate of 1,500 km per second since its explosion over 900 years ago.

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:
One of the showpieces of the northern hemisphere summer sky is this diffuse nebula of hydrogen gas, which can be seen in amateur telescopes quite low in the southern sky, just outside the band of the Milky Way.
Known as the "Omega Nebula" because of the similarity of its shape to the last letter in the Greek alphabet, M17 is a hotbed of star formation.
From Wikipedia: "The Omega Nebula is between 5,000 and 6,000 light-years from Earth and it spans some 15 light-years in diameter. The cloud of interstellar matter of which this nebula is a part is roughly 40 light-years in diameter and has a mass of 30,000 solar masses. The total mass of the Omega Nebula is an estimated 800 solar masses.
It is considered one of the brightest and most massive star-forming regions of our galaxy. ...
The open cluster NGC 6618 lies embedded in the nebulosity and causes the gases of the nebula to shine due to radiation from these hot, young stars."

IC 63 is an emission nebula in the constellation Cassiopeia. It is about 550 light-years from Earth. It is is being shaped by radiation from the nearby variable star, Gamma Cassiopeiae, which is slowly eroding away the surrounding clouds of dust and gas. The star is estimated to be 3-4 light-years from the nebula.
This image is a broadband image using an Antlia Triband RGB filter. I was pleasantly surprised by how pronounced the Ha is in this broadband image with just 45 minutes of integration time.

"Chassis number: SAXXBANB1BD832552. This 998cc Austin Metro MkI has been off-road for a few years, with its last MoT expiring in December 2018, and a subsequent test in October 2020 producing a fail. The current mileage indicated by the odometer is 64,965 miles and the vehicle was registered in May 1983. The vehicle becomes tax and MoT exempt from April 1, 2024 although work will be required to return the Metro to a roadworthy state; however, it does start and drive well, according to the vendor, who believes the mileage to be correct as he has owned the car for nine years. A new battery has been fitted, while new tyres were fitted four years ago. Three keepers overall are recorded on the V5C.
"Documentation with the Metro includes the V5C, a photo of the car at Sandringham during Drive It Day 2016, various old tax discs and a brochure. There's also a Heritage Certificate, while the MoT certificates date from 2012, 2013, 2014, 2015, 2016 and 2017."
No reserve. Sold for £660 including premium.
Taken with the C14 and SBIG STXL-6303 at Cerritos College. The moon was still below the horizon, and the sky was cloudless enough for me to do guided shots. There's always moist air to the south from campus, though, and the limiting magnitude was 17.2 for this image. 16 30 s subframes were stacked to create this. An Antlia L filter was used. The position of the supernova is indicated with white line segments.

ASTAP gives a CV magnitude of 11.8
This was essentially maximum brightness for this supernova.
I realize now that I was not setting apertures properly in ASTAP, and all of my previous magnitude estimates are likely too faint.

Taken early hours of 30th Sept 2021
Many people are familiar with the night constellations, but for some reason I have a mental block and don't organize the sky that way. I prefer taking images like the one above in a wide field to help me understand the positions of deep space objects.
NGC 2903 probably isn't on anyone's dance card. I spotted it while using the Dwarf 3 app on my iPhone (a new feature). Instead of finding a deep space object in a catalog, I held my cellphone to the sky to display objects on the screen in real time. Then I tapped on one (in this case NGC 2903) and let the Dwarf do the rest.

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.

Description:
One of the brightest sections in our home galaxy, the Milky Way, appears in the small constellation Scutum (the Shield), which appears in the southern sky half way from the horizon to the zenith as seen from southern Canada and the northern United States.
In this area appear many foreground cold, dark nebulae, which obscure the light of the stars beyond. These dark regions were photographed and catalogued by the great American astronomer E. E. Barnard (1857 - 1923) (en.wikipedia.org/wiki/Edward_Emerson_Barnard), and bear the designation "B", numbered from 1 to 370.
Near the centre of this view is a favourite target of amateur astronomers with modest telescopes: M11, the "Wild Duck Cluster". 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.

My new winter project. A 1979 Mini 850. Its had rebuilt subframes and a reconditioned engine so drives really nice. I'm intending on a full respray fairly soon but still deciding on a colour!

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 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.

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!
This extends the map of the previous image of Sadr pictured below. Sadr now is the bright star near the bottom. The hazy nebula at the top is the butterfly.
This image is made from 842 separate images called subframes. Each subframe is ten seconds long. Seestar started taking the pictures at 10:54 PM and ended the next morning at 3:48 AM. The total amount of exposure time was 2 hours and about 20 minutes, but because of processing time and dropped frames it took nearly five hours. It took Siril the software used in assembling the images about 2 hours and 12 minutes to put all the individual overlapping images in place.
Flickr Friday theme, sub framing, my choice was the Albert Memorial, so majestic, and such a tribute of love from Queen Victoria to Prince Albert, a worthy scene for sub framing, Happy Flickr Friday.

The sky was reasonably clear, with some thin cirrus cloud, when I was able to get the ten base subframes that make up this view of the Moon high over Toronto early on this mild January evening before the heavier cloud moved in.

Special:
- The SL was designed by Karl Wilfert, Friedrich Geiger and Walter Häcker and as prototype introduced at the 1954 New York Auto Show. The production model was revealed at the 1955 Geneva Auto Show.
- 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.
