M45

I had two clear nights before another storm system was due to come in so I decided to revisit M45 as I knew I could do it justice with just a little bit of data. My last version wasn't deep and mostly focused on the bright stars (https://www.astrobin.com/aanrzj/). This one goes a bit deeper.

Just like last time, I found this a difficult target to process due to the bright stars and halos. I often like to separate the stars from the background and process these two separately. But, this didn't really work out for M45 as the star halos are too integrated into the Merope Nebula. So, I worked on the reflection nebula with the stars in place.

I hope you enjoy. Happy New Year,

Andy

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.
