The Jellyfish Nebula (IC 443, Sharpless 248) is a supernova remnant located in the constellation Gemini. It lies approximately 5000 light years from Earth and can be found between the stars Mu and Eta Geminorum, at the foot of one of the celestial Twins.
The Jellyfish Nebula is a remnant of a supernova that occurred in the Milky Way between 3000 and 30000 years ago. The supernova event produced the nebula and a neutron star. The presence of the neutron star and the nebula’s location in a star forming region indicate that the remnant was created by a Type II supernova, one triggered by a rapid collapse and violent explosion of a star with a mass at least 8 times that of the Sun. The neutron star is moving away from the site at about 800000 km/h.

I'm not sure what the file structure was as I deleted them leaving only the final stacked image which I didn't process for some months,

The Heart Nebula
The Heart Nebula (IC 1805), lies some 7500 light years away from Earth and is located in the Perseus Arm of the Galaxy in the constellation Cassiopeia. It was discovered by William Herschel on 3 November 1787. It is an emission nebula showing glowing ionized hydrogen gas and darker dust lanes.
The brightest part of the nebula (a knot at its western edge) is separately classified as NGC 896, because it was the first part of the nebula to be discovered. The nebula's intense red output and its morphology are driven by the radiation emanating from a small group of stars near the nebula's center. This open cluster of stars, known as Collinder 26 or Melotte 15, contains a few bright stars nearly 50 times the mass of our Sun, and many more dim stars that are only a fraction of our Sun's mass.

It's been a year since I have done astrophotography but the last 2 days of cold and crisp weather has provided a perfect opportunity to get out and image again. This image of the Rosette Nebula (also known as Caldwell 49) was taken from the garden in Aberaeron over two successive nights. The nebula is a H II region located near one end of a giant molecular cloud in the Monoceros region of the Milky Way galaxy. The open star cluster NGC 2244 (Caldwell 50) at its centre is closely associated with the nebulosity, the stars of the cluster having been formed from the nebula's matter. The cluster and nebula lie at a distance of 5000 light-years from Earth and measure roughly 130 light years in diameter (to put this in context, light from the sun takes just 0.000015561 light years, or 8 minutes, to reach Earth!) The radiation from the young stars excites the atoms in the nebula, causing them to emit radiation themselves producing the emission nebula we see. The mass of the nebula is estimated to be around 10000 solar masses.
This image comprises 88 x 3 minute images stacked and processed to generate a final image.

This is a re-edit of the image I posted a few days ago but this time I have managed to pull some of the blue oxygen emission data out from the centre of the cloud.

Aberaeron, Wales
It's a rare event for us to see this so far south, and to have clear(ish) skies to see it. A lot of factors have to align - geomagnetic activity, darkness, no Moon, no cloud and being awake at the time the alarm arrives on the App on the phone to respond in time. Also in the shot is Ursa Major and what looks like two shooting stars but I think the one top right is a satellite and the one above the light post is an aeroplane.
