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!

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.

This planetary nebula (PLN) doesn't belong to the open cluster (NGC 2818A), but have near the same distance to us.

I recently acquired a Starizona HyperStar for my Celestron C9.25 XLT telescope. The HyperStar replaces the secondary mirror on the SCT. It is a lens system that reduces the C9.25 focal length from 2350mm to 525mm and the focal ratio from f/10 to f/2.2. This effectively converts my narrow-field system into a very fast wide-field imaging setup. Using this accessory I can take high quality images of wide-field objects (comets, nebula, large galaxies) in significantly less time than my wide-field refractors (I have two refractors, an f/7 and an f/4.9).

 

My plan is to use the HyperStar to image Comets 2025/R2 (SWAN) and 2025/K6 (Lemmon) once they are at a "reasonable" elevation here in the SF Bay Area.

 

To prepare, I used Andromeda for my first light target to get some practice with the HyperStar. The image above is the result of 45 x 1-minute subs - 45 minutes! This detailed of an image would require 3-4 times the integration time using one of my refractors.

 

I am looking forward to trying the HyperStar to image one or both of the comets now in our vicinity. I am not making any promises, but I hope to post an image of at least one of the two comets within the next 2-3 weeks.

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).

Description:

 

This large, pretty and bright open cluster of stars - which happens to lie in our line of sight in front of one of the bright and star-dense arms of our Milky Way galaxy - is a favourite observational target of northern hemisphere astronomers on summer evenings.

 

From Wikipedia:

 

"The Wild Duck Cluster is one of the richest and most compact of the known open clusters, containing about 2900 stars. Its age has been estimated to about 250 million years. Its name derives from the brighter stars forming a triangle which could resemble a flying flock of ducks (or, from other angles, one swimming duck)."

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.

Special:

- Established in 1871, Benz & Cie. was the most important of several companies founded by Karl Benz.

- Daimler Motoren Gesellschaft (DMG) was founded by Gottlieb Daimler and his partner Wilhelm Maybach in 1890. Daimler died in 1900 and Maybach left DMG in 1907.

- By then, Benz & Cie. and DMG were rivals.

- In 1924, owing to economic necessity after World War I, they entered into an "Agreement of Mutual Interest", allowing each company to manufacture and sell their products under their original brand names. After the official merger in June 28, 1926, the firm became known as Daimler-Benz.

- 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 SLR 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 SL's 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.

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.

Comet C252/P, captured today (2016-04-30) between 0:45h and 2:45h UT in Tenerife, 1180 m altitude. 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.

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.

This is an open cluster in Orion that, when rotated and flipped, resembles the number 37 written in the stars.

 

Subframes were shot on 2022-01-20 and 01-21. Taken with Optolong RGB filters and an Atik 414-EX mono camera on a Celestron Edge HD 925 with an 0.63x focal reducer. This gives a focal length of 1525 mm.

 

R channel: 70 frames of 30 s exposures

G channel: 77 frames of 30 s exposures

B channel: 51 frames of 30 s exposures

 

After preprocessing and compositing the stacks in PixInsight, color was calibrated using the Photometric Color Calibration tool. I played with the saturation a bit and knocked down the background in Photoshop.

This is a colour image of this fascinating region around Orion's belt captured through an 80mm triplet APO refractor using a colour Atik Horizon CMOS camera with a Baader-S filter. I had to wait for both the sky to clear and fireworks displays around me to stop before I could take this image. The image consists of eleven seven-minute subframes stacked. Dark frames have been subtracted but no flats or bias frames used.
