The Crab Nebula (M1), the remains of a supernova recorded by Chinese astronomers in AD 1054. It lies approximately 6,300 light-years from Earth, in the constellation of Taurus. From London it looks very faint indeed and needs far more exposure time than on this picture...but then it had the temerity to set behind houses as it was being imaged.

The Crab Nebula is cataloged as M1, the first object on Charles Messier's famous list of things which are not comets. In fact, the Crab is now known to be a supernova remnant, expanding debris from the death explosion of a massive star. This intriguing false-color image combines data from space-based observatories, Chandra, Hubble, and Spitzer, to explore the debris cloud in X-rays (blue-white), optical (purple), and infrared (pink) light. One of the most exotic objects known to modern astronomers, the Crab Pulsar, a neutron star spinning 30 times a second, is the bright spot near picture center. Like a cosmic dynamo, this collapsed remnant of the stellar core powers the Crab's emission across the electromagnetic spectrum. Spanning about 12 light-years, the Crab Nebula is 6,500 light-years away in the constellation Taurus. via NASA ift.tt/2FIPDhW

M108 & M97
Between 1745 and 1781 French astronomer and comet hunter Charles Messier compiled a list of 110 fuzzy objects that remained at fixed positions in the sky. The purpose of the list was to help people not waste their time observing fuzzballs that don't move across the stars. It was a list of things UNINTERESTING to Messier. Now labeled M1-M110, the complete list of 109 (Wait, wasn't it 110? That's a story for another day...) fuzzy blobs in the sky are known to be star clusters, nebuale and galaxies. A popular astronomy challenge is to observe as many Messier objects as possible in a single night. A fun photographic challenge is to capture images of all 109 objects. I recorded these a few nights ago when it happened to be clear, but the slightly gibbous moon was too bright to bring out any serious detail and dew began to coat the camera later in the night too.
The first image is M1, the Crab Nebula. It is the remains of a star that went supernova, and supposedly the stellar explosion could be seen in daylight in 1054 A.D. The bright star in the image is called Tianguan, in the constellation Taurus, just above Orion's head.
In the second image is M108, an almost edge-on spiral galaxy, and my field of view was inadverdently wide enough to also capture M97, a so-called planetary nebula, the remains of a Sun-like star that has reached the end of its life. The bright star in the image is Merak, one of the stars in the scoop of the Big Dipper.
Hopefully I'll capture better images of these this year, but so far , 3 out of 109 objects captured!

Last night 27-1-2022 proved to be quite difficult, I started with the Iris Nebula, but before gathering the data I wanted next doors tree got in the way, so I moved on to the Crab Nebula to which I was having focus problems, I think I need to revisit my backlash and step settings, I then moved onto the Flame Nebula, again focus was an issue, moving on from there to the Mairan's Nebula at the head of the Great Orion Nebula, very interesting target, as this dipped below my bungalow roof I then moved onto the Needle Galaxy leaving the scope imaging until 4.00am.

Composite image of Messier 1 (Crab Nebula) by NASA's Spitzer and Hubble Space Telescopes, and NASA's Chandra X-ray Observatory
This photo shows a three colour composite of the well-known Crab Nebula (also known as Messier 1), as observed with the FORS2 instrument in imaging mode in the morning of November 10, 1999. It is the remnant of a supernova explosion at a distance of about 6,000 light-years, observed almost 1,000 years ago, in the year 1054. It contains a neutron star near its center that spins 30 times per second around its axis (see below). In this picture, the green light is predominantly produced by hydrogen emission from material ejected by the star that exploded. The blue light is predominantly emitted by very high-energy ("relativistic") electrons that spiral in a large-scale magnetic field (so-called synchrotron emission). It is believed that these electrons are continuously accelerated and ejected by the rapidly spinning neutron star at the centre of the nebula and which is the remnant core of the exploded star. This pulsar has been identified with the lower/right of the two close stars near the geometric center of the nebula, immediately left of the small arc-like feature, best seen in ESO Press Photo eso9948. Technical information: ESO Press Photo eso9948 is based on a composite of three images taken through three different optical filters: B (429 nm; FWHM 88 nm; 5 min; here rendered as blue), R (657 nm; FWHM 150 nm; 1 min; green) and S II (673 nm; FWHM 6 nm; 5 min; red) during periods of 0.65 arcsec (R, S II) and 0.80 (B) seeing, respectively. The field shown measures 6.8 x 6.8 arcminutes and the images were recorded in frames of 2048 x 2048 pixels, each measuring 0.2 arcseconds. North is up; East is left. #L
In commemoration of the 15th anniversary of NASA's Chandra X-ray Observatory, four newly processed images of supernova remnants dramatically illustrate Chandra's unique ability to explore high-energy processes in the cosmos. The images of the Tycho and G292.0+1.8 supernova remnants show how Chandra can trace the expanding debris of an exploded star and the associated shock waves that rumble through interstellar space at speeds of millions of miles per hour. The images of the Crab Nebula and 3C58 show how extremely dense, rapidly rotating neutron stars produced when a massive star explodes can create clouds of high-energy particles light years across that glow brightly in X-rays.
Heavily processed Hubble Space Telescope image of the interior of the Crab Nebula and its neutron star.
This new Hubble image - among the largest ever produced with the Earth-orbiting observatory - gives the most detailed view of the entire Crab Nebula ever. The Crab is among the most interesting and well studied objects in astronomy. This image is the largest image ever taken with Hubble's WFPC2 camera. It was assembled from 24 individual exposures taken with the NASA/ESA Hubble Space Telescope and is the highest resolution image of the entire Crab Nebula ever made.

. Spectral energy distribution of the Crab Nebula from soft to very high energy γ-rays. The Whipple spectrum above 500 GeV (Hillas et al. 1998) is also consistent with these measurements. The fit of the synchrotron component, using COMPTEL and LAT data (blue dashed line), is overlaid. The predicted IC spectra from Atoyan & Aharonian (1996) are overlaid for three different values of the mean magnetic field: 100 μG (solid red line), 200 μG (dashed green line), and the canonical equipartition field of the Crab Nebula 300 μG (dotted blue line).

Heavily processed Hubble Space Telescope image of the interior of the Crab Nebula and its neutron star.
This new Hubble image - One among the largest ever produced with the Earth-orbiting observatory - shows gives the most detailed view so far of the entire Crab Nebula ever made. The Crab is arguably the single most interesting object, as well as one of the most studied, in all of astronomy. The image is the largest image ever taken with Hubble's WFPC2 workhorse camera. The Crab Nebula is one of the most intricately structured and highly dynamical objects ever observed. The new Hubble image of the Crab was assembled from 24 individual exposures taken with the NASA/ESA Hubble Space Telescope and is the highest resolution image of the entire Crab Nebula ever made.
Messier 1 – the Crab Nebula
~6500 Lightyears away in Taurus. It is the remnant of a supernova that was observed as a Guest Star on 4 July 1054 by Chinese astronomers.
The mystery of why a star clearly visible in broad daylight was not recorded in Europe was something I looked into for my final year project. I found no answer!
