Turner Motorsport team mechanic at the IMSA Northeast Grand Prix held at Lime Rock Park. Composed and submitted for FlickrFriday #subframing theme; not only is the subject framed within the frame, but the subframe is a car's frame!
This stack of 18 images contains nearly the entirety of the constellations Andromeda, Cassiopeia, and Perseus. Numerous outstanding objects are within its bounds. From left to right (roughly east to west), they include:
The Pleiades (M45, lower left corner)
The California Nebula (NGC 1499, above the Pleiades)
The Double Cluster in Perseus (NGC 869 and NGC 884, near top center)
The Heart and Soul Nebulae (IC 1805 and IC 1848, above the Double Cluster)
M34 (open star cluster, bottom center)
The Triangulum Galaxy (M33, along the bottom border, right of M34)
The Andromeda Galaxy (M31 and satellite galaxy M110, bright elongated object in lower right area of image)
Subframes were taken with an astrophotography modified Nikon D5100 at ISO 4000 and focal length of 18mm. Stacking and processing in PixInsight, with a few final touches in Photoshop.
The solution for the image from astrometry.net places the center at
RA 2h 3m
DEC +50° 20'
IC 405 also known as the Flaming Star Nebula, SH 2-229, or Caldwell 31,
Seestar S50. This is a composite of 567 ten-second exposures (subframes). Taken January 26, 2025.
This was a tough shot to get. Between light pollution, moonlight, and clouds moving in and out not in accordance to the weather forecast I felt lucky to be able to pull any kind of image from the data. Still I like the painterly quality it has taken on. More like something Whistler would have painted in a nocturne when he was painting his mother.
Dwarf III - 236 30-second subframes. Gain 30. Duo band filter.
Andromeda-Galaxy (M31) over pine trees near my observatory. The circle next to my name represents the apparent diameter of full moon relative to the same conditions. I used the 8 last subframes (of a large series) to an integration (8 x 80 sec, ISO 4000) and one single frame (1 x 80 sec, ISO 400) for a atmospheric composite. Sony A7s (CentralDS), Canon 200/F1.8 @1.8, L-pro filter, EQ8 mount, Tenerife, Canary Islands, 1180 m altitude.
Located in the constellation Triangulum. Takne through NP127is 5 inch refractor at f/4.2. Collected with a Canon 7D MKII. approximately 4 hours total exposure of 7 minute ISO 1600 subframes. Taken at Grandview Campground.
1962 Mercedes-Benz 190 SL Roadster
Further to posting the steering wheel and dash board the other day, here is the rest of the car, which didn't actually sell at the auction last September so it may still be up for sale.
"Announced in 1954 and based on the 180 saloon whose all-independently-suspended running gear it used, the 190 SL did not enter production until January 1955, the delay being caused by alterations aimed at strengthening the saloon's shortened platform to compensate for the open body's reduced stiffness. Mounted on a detachable subframe along with the four-speed manual gearbox, front suspension and steering, the power unit was a 1,897cc overhead-camshaft four - the first such engine ever to feature in a Mercedes-Benz. Breathing through twin Solex down-draft carburettors, the M121 unit produced 105bhp at 5,700rpm, an output sufficient to propel the 190SL to 60mph in 13 seconds and on to a top speed of 107 miles per hour."
M42 The Orion Nebula imaged in HaOiiiOiii. The Ha image is mapped to red and consists of 4 1/2 hours of 60 second subframes. The Oii image is mapped to green and blue and consists of 2 1/2 hours worth of 60 second subframes.
Ha data was captured on the 22nd, 29th and 30th December 2019 and the Oiii data on the 12th January 2020.

I overlayed an extremely blurred, cropped version of this: flic.kr/p/JEStw8 and set the layer to "soft light" as an experiment...
Also I used core data from these:
Horsehead Nebula full: flic.kr/p/22tVKd3
Horsehead close-up: flic.kr/p/P1UuSp
M42 full: <a href="https://flic.kr/p/RWJcUJ"
Processed in PixInsight, assembled in Photoshop 2017
this is actually a reprocessing of the image I took earlier in the year, now that I have a slightly better understanding of how to process astro images, another challenge is that instead of a stack of one hour of data this is simply a single 2 minute subframe stretched, very happy with how it came out
This is a re-process of my original RGB photo from May 2024. An additional 1 hour of luminance subframes was added to the original image stack. Thsi helped to bring out the details of the molecular cloud and trails of dust.
Additional technical details can be seen at my Astrobin page:

Last taxed and last MoT test expired in May 2017.
It failed a test that month -
Offside front windscreen wiper does not clear the windscreen effectively (8.2.2)
Nearside front subframe mounting prescribed area is excessively corroded (2.4.a.3)
Offside front subframe mounting prescribed area is excessively corroded (2.4.a.3)
Nearside front seat belt anchorage prescribed area is excessively corroded (5.2.6)
Offside front seat belt anchorage prescribed area is excessively corroded (5.2.6)
taken from my backyard on May 12 , 2020 just before midnight . 26 subframes 120 sec each stack in PI
For this rendition of the 2-panel mosiac, I ran all of the subframes through the same PixInsight WBPP run so that they would all be at the same local normalization, I applied ChannelCombination to the RGB masters for each panel separately before merging the panels, and I produced separate star and nebula images before applying nonlinear stretches. The stars image was stretched delicately while the nebula image was stretched very agressively. I like the stars that resulted from this treatment.

Each panel consisted of qty 8 240s subs each for RGB, and qty 16 subs for L. Total integration time was 2:20 per panel.
Definition: Sub-framing is a type of compositional photography technique wherein one or more photo elements are framed by another element.
Die Preise werden maßgeblich durch die Rostfreiheit der Karosserie (besonders an Schwellern und Hilfsrahmen), die Originalität (bei Sammlerstücken) oder die Qualität der Motorsport-Komponenten (bei Umbauten) bestimmt.
Prices are largely determined by the rust-free condition of the body (especially on the sills and subframe), its originality (for collector's items), and the quality of the motorsport components (for conversions).

I have wanted to get a detailed shot of this supernova remnant for quite some time. The guiding wasn't perfect this night, but I'm pleased with the overall result. I wonder if I'll be able to do this well enough again in the future to watch the expansion of the nebula that continues from when it appeared in the sky as a supernova in 1054 C.E.

The Packard Station Sedan was a pseudo luxury station wagon model produced by the Packard Motor Car Company of Detroit, Michigan between 1948 and 1950, using the Packard Eight platform. By offering the Station Sedan Packard could market a vehicle with station wagon attributes, but without the investment cost associated with a complete station wagon development program.[2]
The Station Sedan used a combination of steel framing and body parts along with structural wood panels made from northern birch to create a "woody" station wagon-like car due to the growing popularity of them after World War II. Unlike other woody wagons of the day, which used wooden passenger compartments mounted to chassis of a particular car, the Station Sedan used a steel subframe and steel passenger doors onto which hard wood panels were mounted. The only wooden door on the vehicle was the rear gate assembly.[3] Unlike competitor station wagons from Buick, Chrysler and Mercury, the Packard's length was not long enough to accommodate optional third row seating.[3]
Neither a sedan, nor true station wagon, the Station Sedan enjoyed limited success, with a listed retail price of US$3,459 ($38,958 in 2021 dollars [4]) for its final year of 1950, and was discontinued when the 1951 Packard models were introduced.
NGC 2244 also know as the Rosette Nebula is a emission nebula located in the Monoceros constellation.
The nebula is at 5200 light years from earth and is approximately 65 light years wide

As of last week, the Bugatti Veyron is once again the fastest car in the world. The figures are stunning: 8.0 litres, 4 turbochargers, 16 cylinders, 1001 hp, 4wd.
This Lego model has been built to 1:15 scale (16-wide) for Eurobricks 2010 LDD Challenge and features a mid-mounted W8 piston motor, 4wd, four-wheel independent modularised suspension. The vehicle is built to true automotive method. The front passenger tub is technic pin mounted to the rear engine/chassis subframe. All exterior panel except the roof are unstressed and can be detached from the body. The rear spoiler is also height and pitch adjustable.
