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).
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.

Helix nebula (NGC7293), hAlpha, 36 h total exposure time with Hyperstar 14"/F1.9 with ASI 1600 and RASA 11"/F2.2 with ATIK 460, parallel mounted on a ASA DDM85. Single subframe exposure time between 90 sec unbinned for the center structures and 180 sec 2x2 bin for the faint environmental veils. I am very happy how many structures of the environment are getting visible. I look forward to your feedback! Tenerife November 2017.
Now the colour version. During the "Perseid night" I had a lot of luck (and maybe also a kind of skilled serendipity). Tons of luck indead that the meteor is captured in both systems (regarding the 10 sec+ CCD downloading time which is an effective exposure pause). Through the middle of a relatively tiny sky area (FOV 7. 2 x 10. 8 °) I could capture this meteor (which is, however, no Perseid but probably a late Delta-Aquariid) crossing Andromeda Galaxy and with multiple outbursts.
Technique: parallel exposure with two imaging systems:
(1) Canon 200mm/F1.8 (open), SX-36, L-pro filter, 240 sec exposure time,
(2) Canon 200mm/F1.8 (open), Sony A7s (CentralDS modded), ISO 3200, IDAS-V4 filter, 90 sec
both on EQ8 mount unguided.
Final image processed with 32 subframes from each system for the galaxy and the stars resulting in a L-RGB image.
Tenerife, 1180 m alt, 2016-08-12 00:45 UT
Comet 45P, at last there were some subframes usables, with individual background extraction, so that I could integrate some of them. Now the split tail is well visible.
Parallel exposure on ASA DDM 85 mount:
(1) 7 x 60 sec Hyperstar C14/F1.9, Lumicon comet filter, ASI 1600 mono, cooled (-32° C), processed as emerald green in the RGB image.
(2) 7 x 60 sec RASA 11"/F2.2, L-filter, ATIK 490 color, cooled (-18° C)
FOV 1° x 0,9°, location: Tenerife 1180 m altitude. 19:20 h - 19:50 h UT (with many missing subframes due to clouds)
I revisited a bunch of previous RGB data and now added about an hour of Hα data. This galaxy really needs it. All those pink areas are regions of intense star formation, where some of the most massive stars are being born. The particularly big pink blob in the upper right is known as NGC 604. It is an emission nebula in another galaxy that is so large and bright that it gets its own designation. Think of really outstanding examples like this in our own sky -- M17 or the Eta Carina Nebula. This one has both of them beat for size and luminance. It only looks small because it is 3 million light years away.
All subframes shot with a Celestron Edge HD 925 at f/2.3 with Hyperstar. RGB data taken over multiple nights with an Atik 314L+ color CCD; hydrogen-alpha data taken with an Atik 414-EX with Atik 7 nm bandpass filter. Preprocessing of images in Nebulosity; registration, channel combination, and processing in PixInsight; final touches in Photoshop.
NGC2070
I used remote observatory, iTelescope, to took this image.
The plan started at the beginning of September 2019. I acquired L, R, G, B, SII, H-alpha, OIII each 300s*1. I did LRGB, SHO, HOO color mapping, and I found out that the luminous frame is bright (or less noise), but the nebulosity is not as sharp as narrowband frames. Since the SII frame is much dimmer than others, I experimentally took single 900s SII subframe. The Hubble Palette image with S:H:O=9:3:3 still shows water blue color (bule+green) in nebulosity and, badly, very red color in star. I did some google search, notice that there might be not so many SII emission at this place. "Ok, I need to change the strategy." I talked to myself at that time.
After that, I focus on HOO composition. I took an extra nine subframes each with H-alpha and OIII filter. Finally, HOO color nebula combines with LRGB stars makes this image more nature.
The plan will be continuous...

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."

or the 1966 season, Ferrari built a new series of 12 lightweight 275 GTB/C racing cars. Even though they outwardly resembled the road-going 275 GTB, the 275 GTB/C was thoroughly revised by Mauro Forghieri and his Scuderia Ferrari engineering team and differed from both the 275 GTB production car and earlier 275 GTB competition cars. Every panel of the body was altered and substantial mechanical changes were made. All 12 were constructed in 1966 between the end of the 275 GTB (two cam) production run and the start of the 275 GTB/4 (four cam) production run.[14]
Forghieri designed a special super-lightweight steel and aluminium version of the 275 GTB chassis, designated Tipo 590 A. The 4-wheel independent suspension was the same design as on the production 275 GTB, but used different shock absorber valving and stiffer springs. The disc brakes were also the same as those used on the production 275 GTB, but with quick-change racing brake pads.[14]
The body appeared superficially very similar to that of the production 275 GTB series II "long nose", but in fact was a completely new lightweight version constructed by Scaglietti. All body panels were changed, including wider front and rear fenders and a slightly shorter nose. The body was constructed from .028 in (0.71 mm) thick aluminium panels joined with rivets. This method of construction allowed easy replacement of body panels after an accident. The body panels were approximately half as thick as the ones used on the 250 GTO and the Shelby Cobra. This made the body lightweight but extremely fragile—even leaning on a 275 GTB/C would dent it. The entire rear section was reinforced by fiberglass to prevent it from flexing at the slightest impact. The 275 GTB/C was equipped with bumpers visually similar to those on the road version, but they were made of much thinner material. The rear bumper lacked an internal supporting subframe and was simply fastened to the bodywork sheetmetal. Other weight-saving measures included removal of cooling fans, holes drilled in many internal panels and frames, plexiglass side and rear windows, thin fiberglass floor panels, and magnesium-framed seats. A 275 GTB/C fully equipped with fluids, spare tyre and tool kit weighs 2,452 lb (1,112 kg). In race trim without spare and tool kit, it can weigh less than 2,350 lb (1,070 kg), a savings of over 150 kg (331 lb) compared to the alloy bodied road cars.[14][23]
Similar to the four 'Competizione Speciales', the 275 GTB/C was powered by a Tipo 213 V12 tuned to 250 LM specification with a special crankshaft, piston, camshaft connecting rods and sodium-filled Nimonic valves. Many engine castings were made from the lightweight magnesium alloy Elektron. Due to an apparent clerical error, Ferrari did not report to the FIA that the production 275 GTB had a six carburetor option, so only a three carburetor engine could be homologated. In order to make up the loss of power from using only three carburetors, Weber constructed the 40 DF13 carburetor. These replaced the six Weber 38 DCN carburetors used on the 250 LM and were unique to the 275 GTB/C. A dry sump lubrication system was also added, allowing the engine to sit lower in the chassis. The Tipo 213 engine in this competition specification produced 275-282 hp (210 kW) at 7500 rpm.[14][23]
The 275 GTB/C did not use the torque tube driveshaft configuration introduced with the 275 GTB series II, instead using a series I-style open driveshaft which made clutch changes easier during endurance races.The clutch itself was strengthened for the added stresses of racing. The transaxle was a similar design to the road version, but used a lightweight magnesium case, close ratio gears, a strengthened ZF limited slip differential and needle bearings (instead of plain bearings) between the gears and the main shaft.[14]
The 275 GTB/C was fitted with specially-made Borrani wire wheels, sized 7" x 15" in front and 7.5" x 15" in the rear. These wheels were fitted with Dunlop's latest "M series" racing tyres. It was this combination that would prove to be the weak spot of the 275 GTB/C; the tyres had so much grip that they could overstress and break the spokes on the wheels. This resulted in several crashes during competition. After the 275 GTB/C, no competition Ferrari would be fitted with wire wheels again. Two of the twelve 275 GTB/Cs built were sold for street use. Unlike the race cars, these street cars were fitted with standard 275 GTB-style alloy wheels with Pirelli tyre Ferrari
The Fishhead Nebula is in the upper right hand side.
While I'm really happy with how this turned out I think more detail could be revealed with additional data time so I'll probably return to this in the near future.

125 45-second subframes
This is the first time I've attempted to image the Lagoon nebula, which from my location doesn't rise higher than 14 degrees above the horizon while visible from my garden observatory.
It was only after some recent adjustments that allow my south wall to go a little lower when open that I have been able to get one of my telescopes completely covering the target area long enough to image it.
It is a stack of nine seven-minute subframes through a Hydrogen Alpha filter, total image time 63 minutes.

A one owner from new car up until very recent.
Now at 36.5k, this Uno covered only a few hundred miles every year. A clean MoT history bar corroded subframes on both sides in 2013, to which it received the necessary welding.
This is two simultaneously taken views of the region around the Great Orion nebula, M42. On the left a luminance only view taken through my 80mm triplet APO refractor with a ZWO ASI174MM mono CMOS camera, to the upper left the Running Man nebula can be clearly seen.
On the right, through my 130mm triplet APO (the 80mm sits on top of it) usng an Atik460EX mono CCD and three narrowband filters, Hydrogen Alpha, Hydrogen Beta and Oxygen III to create a RGB image. The H Beta filter proved very useful for picking up the whispier parts of the nebulosity. M43 is the small bright nebula towards the top of this image. I was careful to keep individual subframe exposures short enough to stack without the bright part of the M42 nebula obscuring the Trapezium.
