This image is mainly in Hydrogen Alpha, mixed with some green subframes to create a colour image and bring out detail in this faint nebula. It is the sharpest I have managed with my largest telescope following a much needed collimation session. It consists mainly of seventeen five-minute subframes in H Alpha taken through my 12inch SCT, lightly cropped to allow the image to be centred.

NGC 1999 is the reflection nebula at centre right and it is just south of the Orion nebula which is off the right hand edge
of the frame.
This is an integration of 18 hours total exposure shot in multiple 180s and 240s subframes on a QHY168C camera. The scope was a WO Zenithstar 103. Image capture was managed with SGP and PHD2, post-processing was done in PixInsight.

A few shockers in this one for me - the colour for a start - this colour became "fashionable" not that long ago? Certainly not something I would expect to see on a scrapped car anyway. Looking up the history of SL12 NRO, it amazes me to see that it failed an MOT in March 2021 for corrosion to the subframe - it did get repaired and still has a current MOT, with only 58k recorded - but as you can see, it was scrapped. I can happily report that my old Corsa is still on the go, now with 144k on the clock and no serious issues in it's MOT history - how could two cars starting out from the same point have such different histories?
Shot with an STC duo-narrowband filter on a QHY168C OSC camera, this is an integration of 240 x 5 minute subframes. The scope was a WO Zenithstar 103 mounted on a Skywatcher EQ6R Pro. Image capture was managed via SGP and PHD2, all post-processing was carried out in PixInsight.

Description:
The familiar "W" shape of the bright stars in the constellation Cassiopeia rides high in the northern hemisphere autumn and winter sky, with our home galaxy, the Milky Way, running through it and down into the constellation Perseus.
Many large and bright nebulae (hydrogen gas clouds) appear in this area of the sky, along with numerous gravitationally bound open clusters of stars.
Above centre are the bright red hydrogen gas clouds known as the "Heart" and "Soul' Nebulae. For a close-up view of the Heart Nebula made with a 540 mm focal length telescope on the same evening, click here:

Description:
This was my first attempt at photographing this magnitude 8.8 galaxy, which is famous in the history of astronomy, as you will see from reading the description below:
From Wikipedia:
"NGC 6822 (also known as Barnard's Galaxy, IC 4895, or Caldwell 57) is a barred irregular galaxy approximately 1.6 million light-years away in the constellation Sagittarius. Part of the Local Group of galaxies, it was discovered by E. E. Barnard in 1884, with a six-inch refractor telescope. It is the closest non-satellite galaxy to the Milky Way, but lies just outside its virial radius. It is similar in structure and composition to the Small Magellanic Cloud. It is about 7,000 light-years in diameter.
Edwin Hubble, in the paper N.G.C. 6822, A Remote Stellar System, identified 15 variable stars (11 of which were Cepheids) of this galaxy. ... Hubble's detection of eleven Cepheid variable stars was a milestone in astronomy. Utilizing the Cepheid Period-Luminosity relationship, Hubble determined a distance of 214 kiloparsecs or 698,000 light-years. This was the first system beyond the Magellanic Clouds to have its distance determined. (Hubble continued this process with the Andromeda Galaxy and the Triangulum Galaxy). This distance to the galaxy was way beyond Harlow Shapley's value of 300,000 light-years for the size of the universe. In the paper, Hubble concluded the "Great Debate" of 1920 between Heber Curtis and Shapley over the scale of the universe and the nature of the "spiral nebula". It soon became evident that all spiral nebulae were in fact spiral galaxies far outside our own Milky Way."

This is from my light polluted backyard in Long Beach, CA. I mostly wanted to see if I could image a supernova fainter than magnitude 16 from my backyard. Looks like the answer is yes.
2023dbc is a Type Ic supernova. That means the progenitor had shed both its hydrogen and helium layers before exploding. This means the progenitor would have been a Wolf-Rayet star.

Watch out! Fire truck in a hurry to help!
I present to you my version of the fire truck of the 60s. Its distinguishing feature is a nice design, detail, a fairly simple but intricate design and rich functionality.
The machine is equipped with everything necessary, there is a water monitor, hoses, ladder, tool holders, boxes. There are two taps for water supply.
In detail even the bottom, deploying the machine you will notice the imitation of the subframe and the drive system.
Inside you can place a minifigure.
The fire engine blends well with the modular building 10197 and fits in the garage.
Assembled from 322 existing parts.

Description:
Venus is always the most brilliant planet in the sky, and the third brightest celestial object (as seen from Earth) after the Sun and Moon.
The star cluster M45 (commonly known as the Pleiades or the "Seven Sisters") is the best known star cluster in the sky, and is easily visible to the unaided eye, even from light polluted cities (if the sky is very clear).
During this week, Venus approaches very close to M45, and the pair of objects can be seen high in the western sky after sunset, and even into complete darkness.
In this view, composed of 7 stacked identical exposures of 2.5 seconds each, brilliant Venus is at the right side, and the stars of the Pleiades are strewn across the frame to the left.
With long exposures from a good dark sky location, distinctive blue reflection nebulosity surrounds the Pleiades, as seen in this photograph from Sept. 2017:

155 x 240s subframes (10 hours) – Taken on 12/26/2022, 12/27/2022
Processing:
Pre-processing and stacking
- All subframes were calibrated and normalized through WBPP
- The subframes were debayered and split into monochrome channels
- The subframes were registered with distortion correction
- the subframes were registered based on a PSF snr estimate
- The subframes were normalized using local normalization
- Each channel was integrated separately using the ESD clipping algorithm
Preparation of all frames:
- Stacking artifacts were cropped
- the RGB channels were combined to create an RGB image
- the RGB image was plate solved
- DBE was applied iteratively
- the RGB image was photometrically color calibrated
Linear noise reduction
- A low-contrast mask was applied
- Two iterations of TGV noise reduction were applied, one targeting high-frequency noise and one targeting low-frequency noise
- A medium-contrast mask was applied
- MMT targeting all 8 scales was applied to remove large-scale noise
Stretching
- The stars were seperated from the nebula using Starnet 2
- the RGB image was stretched using Arcsinh stretch
Non-linear adjustments:
- LRGB combination
- HDR, LHE, and curves to increase local contrast
- MLT was applied targeting 5 layers of luminance
- The background level was set to .09
- the stars were stretched using Arcinh stretch
- The image was relinearized and the stars were added back

Situated in the heart of our Milky Way galaxy as it passes directly overhead during the summer in the northern hemisphere, the Crescent Nebula is a half ring of ionized hydrogen gas, which glows with a characteristic red-pink colour. The nebula has an angular size of 20' x 10', which makes it about 1/3 the apparent size (in area) of the Moon as seen from Earth.
From Wikipedia:
The Crescent Nebula is an emission nebula in the constellation Cygnus, about 5000 light-years away from Earth. It was discovered by Friedrich Wilhelm Herschel in 1792. It is formed by the fast stellar wind from the Wolf-Rayet star WR 136 (HD 192163) colliding with and energizing the slower moving wind ejected by the star when it became a red giant around 250,000 to 400,000 years ago. The result of the collision is a shell and two shock waves, one moving outward and one moving inward. The inward moving shock wave heats the stellar wind to X-ray-emitting temperatures.
It is a rather faint object located about 2 degrees SW of [the bright star] Sadr. For most telescopes it requires a UHC or OIII filter to see. Under favorable circumstances a telescope as small as 8 cm (with filter) can see its nebulosity. Larger telescopes (20 cm or more) reveal the crescent or a Euro sign shape which makes some to call it the "Euro sign nebula".

I took an image of the Heart Nebula back in the autumn of 2013. While working on that image I was struck by the beauty of IC 1795, the appendage protruding from the "point" of the heart. At that time I acquired a few Ha subframes of IC 1795, but didn't get enough for an image. It's been on my unfinished business list since then.
This year while I was tuning the 16" I thought I'd use some of the time I was testing tracking accuracy to try to check IC 1795 off my todo list. This is the result.
The Heart Nebula itself is IC 1805/SH2 190. The gorgeous center of this nebula is a complex structure that I interpret as being a typical dust pillar, but seen from above rather than the side. If this is the case, then Melotte 15, the star cluster powering this entire complex, must be in front of the central pillar complex. Perhaps the Heart Nebula isn't so heart-shaped at all. It's a more typical hollow cavity, with an incredibly dense pillar on its far inner wall.
There is a considerable amount of oxygen and sulfur in this nebula. This indicates that it is older and much more evolved than most starbirth regions where these elements are much more rare. This is supported by the relative sparseness of Melotte 15. Perhaps many of its original members have been gravitationally ejected from the system and have entered the general population of the galaxy.
Sometimes when I take an image, I ultimately end up rather unimpressed by the result. Not too many people see those results. This one, though... I'm really pleased with this one. This goes into my picture book, and maybe even on my wall :)

Nine years after the the TR7 had ceased production, another British manufacturer, Grinnall Specialist Cars modified existing TR7 and TR8 cars. TR7 cars were upgraded with TR8 subframes and dash. They then installed V8 engines (optionally bored to larger capacities), and other parts like suspension, gearbox and brakes from the Rover SD1. The front and rear wings were widened to match the SD1 axles and suspension. 350 convertible cars were produced, each with Grinnall badging
The Triumph TR7 is a sports car manufactured by BL (British Leyland) at Speke, Liverpool, Canley, Coventry and Solihull, West Midlands from September 1974 to October 1981. The car was launched in the United States in January 1975, with its UK home market debut in May 1976
Designed in house by Harris Mann, who also designed the Princess, it has a distinctive wedge shape, and with a swage line sweeping down from the rear to just behind the front wheel, it was advertised as . The Shape of Things to Come .The car has an overall length of 160 in (410 cm), width of 66 in (170 cm), wheelbase of 85 in (220 cm) and height of 49.5 in (126 cm). The coupé has a kerbside weight of 2,205 lb (1,000 kg).Because of proposed US legislation on roll-over protection at the time of its launch, the TR7 was not initially offered as a Convertible, In early 1979, Triumph belatedly introduced a convertible version, called the TR7 DHC (Drophead Coupe)
Power is provided by a 1,998 cc eight-valve four-cylinder engine that shares the same basic design as the Triumph Dolomite 1850 engine, albeit increased to 2 litres and fitted with larger carburettors, mounted in-line at the front of the car. Power is 105 bhp
For export to the US market, Triumph created a much more powerful Triumph TR8 model in 1977/78, which was a TR7 with a 135 bhp (101 kW) 3.5 L Rover V8 engine. While some genuine TR8 models stayed in Britain
