Crescent Nebula

A fascinating and mesmerizing target by all means.
This was my first time I try to add OIII data to an image. The image was capture during three nights, where the last night I used the Antlia ALP-T Dual band filter.
I then used pixel math to extract the Ha and OIII and combine them with the stack from the other 2 nights. I am sure my execution of the pixel math was very basic, but overall I am very happy with those blue wisps and how the Ha regions looks. This is a technique I will definetly be diving deeper into.

If someone has insight into this topic and wants to share their knowldege I would really appreciate it.

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.
