M45 The Pleiades

This image was the other half of the frantic, didn't expect the skies to clear, imaging night where the previous image of Markarians chain was produced. I tried something different with this because of the really bright stars and the horrible micro lensing of the 1600MM. I used 20 second exposure and tried to capture as many as I could until M45 set to low for me to continue imaging. I ended up with 560 sub frames. I was hoping I could avoid 1600MM issues and still get a decent amount of nebulosity in the image.

This took me 14 iterations of processing to arrive at an image I was somewhat happy with. Trying to balance the bright stars with the dust was a challenge.

Overall I am happy with the image with only 3hrs integration. I really want to fully capture the full extent and detail of the dust and the deep saturation of the reflection elements. I could get more deeper saturation with more integration time and with different sub lengths for a HDR processed image, maybe next year!

Description: took the highlights down a bit, was way to overstretched in the whites. Was trying to show more dust but took it to far, so tuned it down a bit.

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.
