SH2-308. I'm going to capture more data of this amazing object in a few days but thought i'd share the image. This is 14*480sec subs in Ha and 16*600sec subs in o3. HOO palette. Helpful comments most welcome.

Description: Not a revision so much as trying this again with new filters to see if i could get rid of the horrible halos you can see in the original image. For this revision, I mixed in RGB with the Oiii to get more colourful stars. While I did add in some Ha, i definitely need more data in order to bring out the red Ha - not that there is much.
I'm not that experienced mixing RGB with NB so i used the NBRGBC script in Pixinsight to put it all together in a linear state and then used curves and some noise reduction to produce the final image. Let me know if there is a better way to do 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.
