Bode's galaxy, reprocessed using StarTools 1.8.
this image place an emphasis on star colors. For this image, I used the Astronomik RGB filters.
Around M81, a good mix of blue, yellow and red stars can be found.
Blue stars are hot 10,000 to 60,000 kelvin (surface temperature)
white stars are 6500 to 10,000 k
yellow stars like our sun, 5,000 to 6500k
red stars are less than 5,000k at an average temperature of 3,000 kelvin.

The mass, luminance and life duration of a star are somewhat related. The larger the star, the faster hydrogen is consumed. Some larger blue giant stars will burn hydrogen only for millions of years, whereas our yellow sun, will consume hydrogen for billions of years.

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.
