M101 and Supernova SN 2023ixf

The majestic Pinwheel Galaxy, M101 and a new supernova SN 2023ixf imaged over two nights on May 24 and May 25 from Pine, Arizona. The supernova is seen as a bright blue star in the spiral arm next to the star forming region NGC 5461. SN 2023ixf is a type II-L supernova resulting from the collapse and violent explosion of a massive star. At the time of imaging, SN 2023ixf reached the brightness of 11 magnitude, 6% of the total brightness of its host galaxy, M101.

This LRGB was taken with my mobile setup, the 250mm f/4 Lacerta PhotoNewton and ASI294MM Pro camera riding on the Orion HDX-110 EQ-G mount. The luminance image is a combination of a series of 180s exposures taken at camera gain 0 and 90s exposures taken at gain 108. The RGB color data is comprised of 180s exposures taken at gain 108.

L: 24x180s (Gain 0, bin 1x1), 81x90s (Gain 108, bin 1x1)
R: 48x180s (Gain 108, bin 1x1)
G: 40x180s (Gain 108, bin 1x1)
B: 39x180s (Gain 108, bin 1x1)
Total exposure: 9.6 hours

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.
