First light with QHY294C OSC / one-shot color/ camera . Testing for best setting and best capturing software but weather not cooperating, nice hot beautiful summer days but hazy nights. For this stack, I choose only 23 subframes, 60 sec each from 100 's using SubframeSelector in PixInsiaght. I hope I'II grab more and reprocess image soon. All processing done in PI included StarMask, all bright stars saturated so I did not touch them. This camera is so sensitive and captures so many bright stars especially on Milky Way take so much time to process. I used a Sequence Generator, When I am using SharpCup I am not relaxed because is downloading all the time video frames and crushing often.

Special:
- The body was designed and built by Pininfarina, based on the Battista Farina's “Florida II” show car of 1957.
- The name "Flaminia" is derived from an ancient Roman road.
- It was a quality built car with quality materials like aluminum (i.a. doors, fuel tank, B-pillar panels), brass nuts, walnut (i.a. dashboard, internal trim) and narrow gaps between parts.
Back in the 50', people would regularly hit the road embarking their little families out for a WE, also for holidays or just go picnic, for doing so they needed spacious cars. This relic, standing in the backyard of a repair-shop, awaiting better days, just reminded me of those hopeful times :-)
The Panhard Dyna Z is a lightweight motor car produced by Panhard of France from 1954 to 1959. It was first presented to the press at a Paris restaurant named "Les Ambassadeurs" on 17 June 1953 and went into production the following year. In 1959 it was replaced by the Panhard PL 17.
Panhard was one of the world's oldest auto manufacturers and since 1945 had become known for producing economical cars. Panhard, like Citroën, considered itself a leader, not a follower of automotive trends, and the Dyna Z featured an impressive array of unusual engineering choices.
In 1955 Citroën had taken a 25% holding in Panhard's automobile business and during the next two years the national dealership networks of the two businesses were integrated. This gave Citroen and Panhard dealers an expanded market coverage, incorporating now a small car, a medium-sized saloon and a large car range. It gave the Panhard Dyna Z, during its final years in production, a level of market access that its predecessor had never enjoyed. Sales benefited.
The Dyna X was replaced by the more streamlined Dyna Z in 1954. This was later developed into the similar PL 17, launched in 1959, in an attempt to conform to the styles of the time.
Like its predecessor the Dyna X and the Panhard Dynavia concept that influenced its design, the Dyna Z's body was originally aluminium with steel tube subframes front and rear joined by steel plate reinforcements in the sills. The decision to use aluminium sheeting for car bodies had been taken at a time when a sudden drop off in demand for fighter planes had left the producers with a glut of the metal, but in subsequent years the relative cost advantage of sheet steel had increased steadily. Other sources emphasize an underlying error with the original costings for the model which had taken no account of the off-cuts from the aluminium coils after the blanks for the body panels had been cut from them. Jean Panhard's explanation to a sympathetic interviewer concludes with the observation that "nobody wanted to buy offcuts except at a ridiculously low price, this difference was our profit margin." In Summer 1954 the cost penalty of persisting with aluminium bodywork had become financially unsustainable, and from September 1955 the Dynas Type "Z1" switched to steel bodywork, even though the door shells, trunk/boot and hood/bonnet were at this stage still made of aluminium. The switch to a sheet-steel body shell, attributed to "various setbacks" ("nombreuses déboires") with the aluminium body of the earlier Type Z1, imposed an instant weight penalty of 123 Kg. and had to be accompanied by a substantial redesign of the front suspension and a change to the shock absorbers, though cost savings were too late to avoid the need for Panhard to sign their ultimately suicidal refinancing "agreement" with Citroën in April 1955.
By 1958, only the bumpers, the fuel tank, the engine cooling shroud and most of the engine and transaxle cases were aluminium, but the weight was still quite low for a relatively comfortable six-seater saloon, when compared with narrower competitor models from Peugeot and Simca. Its unusual and very modern design gave it a unique combination of space, ride comfort, performance and fuel economy at a very competitive price. But reliability suffered and fuel prices were not high enough, even in France, for people to put energy efficiency first. The car also suffered from some engine and wind noise. The Tiger version had a racing inspired engine and a full cooling shroud.
History
Panhard was originally called Panhard et Levassor, and was established as a car manufacturing concern by René Panhard and Émile Levassor in 1887.
Early years
Panhard et Levassor sold their first automobile in 1890, based on a Daimler engine license. Levassor obtained his licence from Paris lawyer Edouard Sarazin, a friend and representative of Gottlieb Daimler's interests in France. Following Sarazin's death in 1887, Daimler commissioned Sarazin's widow Louise to carry on her late husband's agency. The Panhard et Levassor license was finalised by Louise, who married Levassor in 1890. Daimler and Levassor became fast friends, and shared improvements with one another.
These first vehicles set many modern standards, but each was a one-off design. They used a clutch pedal to operate a chain-driven gearbox. The vehicle also featured a front-mounted radiator. An 1895 Panhard et Levassor is credited with the first modern transmission. For the 1894 Paris–Rouen Rally, Alfred Vacheron equipped his 4 horsepower (3.0 kW; 4.1 PS) with a steering wheel, believed to be one of the earliest employments of the principle.
In 1891, the company built its first all-Levassor design, a "state of the art" model: the Système Panhard consisted of four wheels, a front-mounted engine with rear wheel drive, and a crude sliding-gear transmission. It would remain the standard until Cadillac introduced synchromesh in 1928. This was to become the standard layout for automobiles for most of the next century. The same year, Panhard et Levassor shared their Daimler engine license with bicycle maker Armand Peugeot, who formed his own car company. Source Wikipedia.
The Rosette Nebula consists of an open star cluster and a large emission nebula. It is a few degrees east of the star Betelgeuse in the sky. Although I have captured it many times in wide field shots of the area around Orion, I never made a dedicated effort on the nebula itself before this. The light used here was all from the 656 nm line of hydrogen emission. I might go back later and add an oxygen channel, but I thought this result was worth sharing.
I shot this mosaic over seveal nights from 2022-01-28 through 2022-02-01. It's a five panel mosaic, with stacks of 2 minute exposures for each of the five tiles, ranging from 31 up to 54 subframes. Imaging was done with a Celestron Edge HD 925 with Hyperstar and an Atik 414-EX monochrome CCD with an Atik H-alpha filter. Preprocessing in Nebulosity; mosaic compilation and other processing done in PixInsight.

Description:
I cannot think of a more famous or more often photographed and observed object in the night sky than M42 & 43 in the constellation Orion. This nebula is visible to the unaided eye smack in the centre of the sword of Orion, hanging down from Orion's three-star belt.
From Wikipedia:
"The Orion Nebula ... is one of the brightest nebulae, and is visible to the naked eye in the night sky. M42 is located at a distance of 1,344 ± 20 light years and is the closest region of massive star formation to Earth. The M42 nebula is estimated to be 24 light years across. It has a mass of about 2000 times the mass of the Sun."

Description:
This comet has been touted as the brightest in a generation. The last comet that I can remember being this bright was Comet Hale-Bopp in 1997, which was undoubtedly the best comet that i will have seen in my lifetime.
This visitor to the inner solar system was discovered on March 20 this year by astronomers during the NEOWISE mission of the Wide-field Infrared Survey Explorer (WISE) space telescope (hence the name of the comet). It reached naked eye visibility this month, and I finally got into a dark sky - with no Moon in the sky to wash out the fainter outer reaches of the tail - on July 17.
In this view we see the bright head of the comet at the left side, with the broad yellowish dust tail fanning out to the right, and the fainter, narrow bluish plasma or ion tail bordering the dust tail at the top.
At the time of this photo, Comet Neowise was 78 million km (0.52 astronomical units ("AU") - the distance from Earth to the Sun) from the Sun, and 109 million km (0.73 AU) from Earth, and shone at a brightness of third magnitude, with a 10 degree tail.

The weather has been so bad in southern Ontario for the last almost two months that tonight was the first time since Nov. 22 that I have had the telescope out under a clear sky!
The Moon, in its waxing gibbous phase and 78% sunlit, was riding high over Toronto tonight, just four nights before the total eclipse of the Moon this coming Sunday night. It was quite cold, but there was no wind to blow the telescope around, so I was able to get very clear, high resolution base images from which to make this image.

High in the northern hemisphere summer and autumn sky our home galaxy, the Milky Way, runs through the constellations Cepheus (left side) and Cygnus (right).
This area of the sky is riddled with glowing red clouds of hydrogen gas, numerous star clusters, and areas of dark foreground gas that obscures the light of millions of stars beyond.
Above and to the left of centre is the bright circular red gas cloud IC 1396. For a close-up view of this nebula made with a 540 mm focal length telescope later the same evening, click here:

Description:
This faint and visually very elusive nebula can be photographed to advantage only in a good dark sky.
Known as the "California Nebula" because of its shape, this glowing cloud of red hydrogen gas is quite large; about five times as long as, and a little wider than, the Moon appears in our sky. The nebula is located 1,000 - 2,000 light years from our solar system, and is about 100 light years from end to end. Radiation from the nearby blue-white star Xi Persei (the brightest star in the frame, below the nebula) causes the nebula to fluoresce.
The California Nebula was discovered by famed American astronomer E.E. Barnard in 1884-5, just in time to be added to Dreyer's New General Catalog (NGC).

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)

This a monochrome image that was captured in Ha narrowband only, with subframes of 10 minutes each. I had intended to capture OIII and SII as well, but the target was above my limited southern horizon for only about an hour. More to come if I can get some more limited "peeks" before its gone for this season, and certainly more to come if I go to WInter Star Party next year.

This is my best comet image to date. I can see a fair amount of detail in the dust tail, and a decent showing of the "forward" pointing ion tail.
I am not able to identify the fuzzy blob seen directly above the nucleus as seen in this image. PixInsight Annotation script does not show an object at this location. I cannot see an outburst in any of the subframe data. Please comment with any ideas.

Special:
- The Beta (1972-1984) was the company's first new model introduced by Lancia after it had been taken over by FIAT in 1969.
- Vincenzo Lancia used letters of the Greek alphabet for his early cars, like Alpha, Beta, Gamma, etc., and as such, Beta had been used on two previous vehicles.
- This 2+2 Coupé, designed in-hous led by Aldo Castagno (Lancia) and Pietro Castegnero (from Carozzeria Pininfarina S.p.A., Cambiano - Italy, but acting as styling consultant), is based on a shortened Berlina chassis (100 inch) and has also the first ever multi-link rear suspension used in a mass produced car, designed by Sergio Camuffo.
- The Beta Series was assembled in Turin (Italy) and in Pamplona (Spain).

His Name is Stephan. and he is german. we travelled around with him for a couple of days and ended up sharing a bamboo house boat in Kerela for a night. During My three month stay in india, i met many different people from all over the world. After meeting Stephan, i can now say that Germans are my favorite! i love the ripples around his body and how they subframe him into a little motif

Description:
This comet has been touted as the brightest in a generation. The last comet that I can remember being this bright was Comet Hale-Bopp in 1997, which was undoubtedly the best comet that i will have seen in my lifetime.
This visitor to the inner solar system was discovered on March 20 this year by astronomers during the NEOWISE mission of the Wide-field Infrared Survey Explorer (WISE) space telescope (hence the name of the comet). It reached naked eye visibility this month, and I finally got into a dark sky - with no Moon in the sky to wash out the fainter outer reaches of the tail - on July 17.
In this view we see the bright head of the comet at the bottom near the horizon, with the broad yellowish dust tail fanning out to the right, and the fainter, narrow bluish plasma or ion tail bordering the dust tail to the left.
At the time of this photo, Comet Neowise was 78 million km (0.52 astronomical units ("AU") - the distance from Earth to the Sun) from the Sun, and 109 million km (0.73 AU) from Earth, and shone at a brightness of third magnitude, with a 10 degree tail.
