M45. Still dealing with a stripe of color 240 pixels wide that runs through the center of the image from bottom to top that forced me to do some processing that I didn't want to in the short term. When I have more time I will try to be a bit more delicate. Still fairly happy with the image although fairly frustrated trying to figure out what is causing the stripe. My current suspicion is bad flats. I'm going to take a new set of calibration frames to try to figure out the issue.

This was also my first night successfully guiding and also using SharpCap Pro for polar alignment. So major milestones in using my equipment.

Description: Second process attempt. I was a bit more delicate to not bring out the color stripe that I have been fighting. I also didn't desaturate the image outside of the cluster out of frustration this time. Much happier with the result overall.

I still want to try new calibration frames to see if I can improve upon it even more.

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.
