Messier 101, also known as the Pinwheel Galaxy is a spiral galaxy far, far away. It's accompanied by the galaxy NGC 5474 (Lower left) which is distorted by the gravitational pull from the much larger Pinwheel Galaxy.

This image is a combination of "regular" photograph and a filtered one which only shows hydrogen. This is why you can see these red veins which aren't that prominent on a regular photograph.

This is the first serious attempt to capture something with my Newtonian telescope. As usual not everything went smooth and I had quite some trouble to get it to focus correctly. Also I had quite some trouble to pull the color out and it's still not where I would like it to be. Maybe I've done something wrong during color calibration or I need to change something with my telescope .. that I still need to figure out.

Anyway I'm quite pleased with the details I've got.

A large spiral galaxy with extending arms around it. On the outside it is quite blue while it gets more yellowish moving to the inside. All across one can see red veins where there is hydrogen.

Phenomenon, spotted around galaxy #NGC6505 some 590M light-years from Earth, reveals the warping of space predicted by Einstein's theory of relativity. The background galaxy, located 4.42B light-years away, appears as a complete ring of light around NGC 6505.

JWST NIRCam and MIRI image of Arp 142, also known as NGC 2936, NGC 2937, and UGC 5130, or the Penguin and the Egg.

The Penguin is a spiral galaxy whose shape has been distorted by the gravity of the elliptical Egg galaxy. The two are about 100,000 light-years apart and completed a close pass between 25 and 75 million years ago.

Arp 142, two interacting galaxies, observed in near- and mid-infrared light. At left is NGC 2937, nicknamed the Egg. Its center is brighter and whiter. There are six diffraction spikes atop its gauzy blue layers. At right is NGC 2936, nicknamed the Penguin. Its beak-like region points toward and above the Egg. Where the eye would be is a small, opaque yellow spiral. The Penguin’s distorted arms and orange dust lanes from the bird’s beak, back, and tail. The tail is wide and layered, like a beta fish’s tail. A semi-transparent blue hue traces the Penguin and extends from the galaxy, creating an upside-down U over top of both galaxies. At top right is another galaxy seen from the side, pointing roughly at a 45-degree angle. It is largely light blue. Its length appears approximately as long as the Egg’s height. One foreground star with large, bright blue diffraction spikes appears over top of the galaxy and another near it. The entire black background is filled with tiny, extremely distant galaxies.
