IC434 - Testing Antlia Quad Band Anti-Light

Link: https://www.palaferri.com/ic434/

Hello, I am testing the new "Antlia Quad Band Anti-Light" filter. This is my first acquisition, but on very bright stars like Alnitak, it created a strange halo, with an exposure time of 300 seconds. The strange thing is that the same subject with the same exposure but using the Antlia Triband filter did not produce the same result. What do you think could be the reason?

I believe I should reduce the exposure time, what do you think? In any case, I managed to recover that part in post-production, and I will share the result of the processing with you.

good news, the problem on IC434 is not visible, there are no artifacts, with 150DP F4 Skywatcher and ZWO ASI 294 MC, under the single 300" image from Alnitak.

I think we can conclude that the problems I encountered at the beginning were due to the RC8 setup.

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.
