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'
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.
420 thirty-second subframes.
I imaged the Flaming Star Nebula using two different smartscopes with dramatically different results. There were also differences in post-processing that influence the differences. The two smartscopes' cost was nearly identical. No one scope is better than the other, but each has a distinct look. See below for comparison.
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.
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.
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.

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."

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 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.
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
Not to be confused with the Loch Ness Monster Nebula.
LdN-768 on the left side a bit below the middle.
I would like to take this image again’t with the Dwarf 3 to capture a bigger section and get slightly better resolution.
Seestar S50
582 ten-second subframes.
Members of NIghtSky45 (an astronomy club) went to Antalope, Oregon to take astro photos. The darker the sky, the better. But clouds covered the area both days we were there. About 3:00 am on the last night I woke to see that the clouds had partially lifted. I took this image during about a one hour opening.
I think I'm going to collect data on this image and add to it when we get more clear night skies.
Dwarf 3
72 45-second subframes.
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
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.
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.

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.

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.
