This is the final result after capturing extra frames in H-alpha, CLS and OIII on June 14th of M16.

The SII were not satisfying, so I decided not to continue with that imaging run.

On sunday June 7th, the moon glow was quite severe and added an unpleasant gradient,

which was removed from the CLS channel with relative success.

I decided to take an extra run of subframes two weeks later on June 14th under clear skies and moonless conditions.

It is pretty much all I could do for now.

Maybe the advice would be to avoid targets that are below 30 deg from a bright moon.

I might keep last night's H-alpha frames for future integration

as they were contrasty good frames and definitively drop the June 7th frames

Narrowband filters can help but they have limited capabilities under these circumstances.

The moon glow was serious business even for the CLS filter (I had to digitally balance severe sky gradient) due to the

angular proximity of this object and the moon on June 7th (18 deg).

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.
