Orion & Horsehead, Narrowband

This really shows how wide the field is with the Redcat. The previous two posts showing only the Horsehead and the Orion Nebula were taken from this data. I thought cropping the image to the two separate targets would create something that was visually more appealing but I actually think this one is better. The noise is still there but perhaps not as bad as in the cropped images (to which I didn't apply any flats or bias frames).

If anyone has any tips for getting rid of (or at least reducing) the halos around the brighter stars, I'd love to hear them! I'm pretty sure these are an artefact of the narrowband filter.

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.
