Flying Bat and Seahorse Nebula

Challenging target win? or narrowband epic fail?

Trying to get the Flying Bat with the neighboring Seahorse Nebula all at once from the Bortle 7 backyard with an L-Enhance filter was going to be extra tough. The relatively large band pass in the OIII region let me capture a lot of the dust in the area bringing out the Seahorse from the background quite well, but hidden within the Flying Bat is the Squid. It is all but invisible with the Hb signal trumping the pure OIII signal from the target.

Also, any tips for either:
1. Getting the L-Enhance to not have halos when put into a ZWO Canon-EF lens filter drawer?
2. Removing the halos in post processing?

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.
