The Pleiades (M45) - First Attempt

Still having fun learning the ropes with the new WO GT81, and now have the field flattener/reducer in the rig...

This is my first try at imaging the Pleiades (M45). I've certainly seen better captures, but I was pleased that the faint reflection nebula was at least somewhat visible. I captured ~2 hours of data over the course of two nights for this image, and this was also my first attempt combining data sets from multiple nights. I plan to add additional data sets this winter, and hopefully the final result with show much more of the reflection nebula.

M45 imaged with WO GT81 at F4.7 (382 mm focal length) using Flat6A II field flattener/0.8x reducer and Nikon D750. Stacked using DSS for a total integration time of ~2 hours using 120 sec subs at ISO 200. Subtracted darks, bias, and flats. Processed in Pixinsight: Cropped, gradient removal with DBE, Background Neutralization, Color Calibration, SCNR, stretched using Histogram Transformation Tool, Curves Transformation, HDR Multiscale Transform, ACDNR noise reduction, Morphological Transformation to shrink stars.

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.
