Westerlund 2
I was always intrigued by the HST image of the cluster Westerlund 2.
It is in the middle of NGC3247 also called Gum 29 or Rcw 49.
The image is a small crop of the field, luckily the seeing was very good.
It is a SHO narrowband with RGB stars.
Usually the RGB stars are pretty bloated in comparison the th NB stars, so what I did is to apply the RGB stars just as color layer to the NB stars.
Hope you enjoy it.
Wolfgang

Title: Different Approach

Description: Here is a new version that resembles more of a RGB look. It is still a SHO with RGB stars but I used the NarrowbandHueCombination tool in Pixinsight, Ha is mapped to red, SII to yellow and OIII to blue.

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.
