The Pleiades (M45) - RGB

Took advantage of the new moon and angle of availability to run a quick test shot of M45 with RGB only on the ASI1600. Not sure if L is useful on this subject.

50x 60s each filter, unity gain (139), 0C.

darkarchon's EZ Processing Suite was again useful to me for nice linear noise reduction better than my normal workflow, and also star reduction.

As feared, the "microlens" artifact from the camera's sensor is prevalent on these bright stars, and it was not possible to do more than minimize that in processing. I'll give this another run one day with a different mono camera. Meanwhile, this maybe slightly betters last year's run with the ASI071 OSC with also less integration than this year.

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.
