2.5-hour Exposure of the M101 Galaxy with Supernova 2023ixf (and A Comparison to Last Week's)

Here is the M101 with supernova 2023ixf (The bright star at the lower right of NGC 5461) captured last night through the gaps in the clouds, from midnight till early morning (5/22/2023). After sorting, only about 2.5 hours of subframes were usable. Fortunately, the efficiency of the 0.5-meter telescope is barely acceptable, and the final processing yielded a work with a decent SNR.

The photo for comparison before the supernova explosion were taken on 5/9, 5/10, 5/11, 5/12 and 5/15, with a total exposure time of 8 hours and 5 minutes.

Both photos were post-processed using the same approaches and arguments.

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.
