NGC 288 from the backyard.

A yellowish image of the nice NGC 288 globular cluster. It is in the sculptor constellation and quite close to the famous sculptor galaxy. One thing quite interesting about this cluster is that the core is not extremely dense, so, in the image it can be identified stars even from the centre.
One motivation to try this cluster was the small galaxy GSA N02 or PGC 3068, I found nice to try other objects in the vicinity of the globular clusters.
This is the Hubble image, as usual, an amazing one, it also shows the abundance of more yellow stars (visible spectrum) https://esahubble.org/images/potw1111a/
I will try another stretch to see if I can improve the colour, enhancing also the blue stars.

Title: Different colour calibration

Description: I did a different colour calibration not considering photometric colour calibration, actually that was causing to go yellowish. So, now you can distinguish a wider variety of star colours within the cluster. Of course, the spectra looks a bit up, but it gave a better overall result.

Title: New colour calibration

Description: As before, I did not use photometric colour calibration but autocolour instead. Next I adjust the levels to get closer to well know images of the cluster from observatories.

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.
