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!
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.
Everybody's favorite. This version has plenty of space surrounding the galaxy and shows good detail.
Dwarf III | 200 fifteen-second subframes | gain: 60 | Astro filter | mosaic mode | Equatorial mount
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.

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).

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:
I've heard of the Pacman Nebula for a long time and it's not too hard to see the shape that earned its name. I've always zoomed in trying to catch as much detail in the nebula as possible. But this time I zoomed out and notice that there was more to the Pacman identity than just the shape. Viewed from the right angle it appeaAptera that the nebula is rushing ahead to gobble up ⍺Cas. Video game at an astronomical level!

Description:
Among the most photographed and examined areas of the sky is this region surrounding Alnilak, one of the three bright stars in the Belt of Orion.
The Horsehead Nebula: The famous Horsehead Nebula, which was first photographed and identified in 1888 by Scottish astronomer Williamina Fleming at the Harvard Observatory, is a foreground cloud of dark gas that is seen in silhouette against a background red hydrogen gas cloud.

The Zeta Orionis (Flame) Nebula: The large, intricate pale pink nebula to the lower right of the brightest star is the Flame Nebula (NGC 2024), which is located between 900 and 1,500 light years from our solar system.

For this image I took two photos of two horses looking over a fence, I then superimposed a close up of one of the horses, reduced it in size and repositioned it onto the original image which I made black and white.
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.
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.
M51 - The Whirlpool Galaxy
Easily one of the most photographed deep sky objects, M51 never ceases to amaze me. My first ever astrophoto in 2012 was of this galaxy, and I've shot it pretty much every year since, constantly improving on what had come before. This year was no different other than the amount of data I had.
I shot this over many nights in the spring and early summer despite having a lot of cloud cover to deal with. Overall, I had about 12 hours of data, but much of that didn't quite measure up due to clouds blowing through, deteriorating my images. It look me quite a long time to go through hundreds of images manually to weed out the obviously bad stuff until I had just shy of 8 hours of data. Then finally in stacking, I whittled that down even further.
This is the final image with 6 hours, 10 mins of data made up of a mix of 3 and 5 minute exposures.
