M45 Pleiades south of the city

This has been and always will be one of my favorite captures. I have a Tak Epsilon on order and a trip planned for Bortle 1 skies in November, This is the Primary target for that scope. The dust (that my Bortle 6 skies cannot capture in only 8 hours) is so amazing. I will continue to add more and more data as I can through the years to this target.

The sweeping color swaths. AHHH... hope you enjoy.

processing Pixinsight:

HDR lum created and used for Decon

Crop

Color workflow

DBE individually with careful attention to dusty regions.

BGN and color calibration; MLT for Noise reduction with mask selection

Lum workflow~

DBE

decon with autopsf 50 iterations 5 layers;

MLT for noise reduction

HT for Lum with Bg at 12% for both color and Lum

TGVDN

LHE after for small and larger kernels masked for the nebula regions

Multiple masks for Curves with range and color and Lum masking for lightness and sat boost

XPTR with Lum mask for lum boost;

MLT for sharpening.

Morph to reduce the stars two iterations and then background brought up again with balance agains the noise in the dust regions due to Sky limits.

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.
