M45, The Pleiades in natural color

This is the Pleiades in natural color made with my new astrophoto stretching software. It came out so blue, I researched the photometry of the nebulosity. With a daylight white balance where solar type stars are white the B-V color of the nebulosity is about -1.2, which is very blue. The blue should be similar to our daytime sky when it is very clear (e.g. high elevation mountain scene with no haze). The image was stretch with a one-step command. Post stretch was small subtraction of some residual light pollution and airglow.

The image is 26 minutes with a 300 mm f/2.8 telephoto and stock 7D Mark 2 digital camera. Stretched with rnc-color-stretch. More infor here:

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.
