Late June 2023 image of Pinwheel Galaxy (M101) with supernova SN 2023ixf (HaLRGB processing)

I captured the Pinwheel Galaxy (M101) last year, but I processed the colour image only now. I used a 12 cm (4.7") refracting telescope SW Esprit 120ED APO and a monochrome camera with Sony IMX571 sensor. The galaxy is displayed in its natural colours, albeit enhanced, allowing for better visibility of the subtle structure of this massive galaxy. The image also depicts a supernova eruption, which was the most significant event in this galaxy for astronomers last year.

The white-blue colour of the galactic spiral arms indicates the presence of young and hot stars. In the yellowish core, older stars predominate. Brownish-red areas reveal cooler and denser regions of the galaxy. In the pink-coloured areas, ionized hydrogen is present, emitting dark red light, but in combination with the blue light of the spiral arms, it gives the appearance of pink hues.

The Pinwheel Galaxy is in the Ursa Major constellation. It is visible even with binoculars and smaller telescopes. Unlike most other spiral galaxies, which usually have symmetric spiral arms, those of the Pinwheel are slightly distorted. Scientists believe that this shape is a result of gravitational influences from neighbouring galaxies. The Pinwheel is exceptionally large, with a diameter of approximately 170,000 light-years, and it contains as many as 1000 billion stars! It is in our cosmic neighbourhood, located 21 million light-years away. Scientists have extensively studied the Pinwheel Galaxy and some other galaxies, contributing to a deeper understanding of galactic evolution and the size of the observable universe.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
