Horsehead Nebula B-33 / IC-434

Revision title: Star reduction

With all the clouds now in my neck of the woods, I've struggled to get any really solid data on this object. Originally I had planned to go for 10+ hours on this but even after 4 days of in between holes I struggled to even get this 5.4hrs of data. My hope is at some point is to shoot more data and add to this image so that it will help cleanup the noise out of it.
While I'm not super happy with this image, it is the best image to date I've taken of this object.

I shot 1.3hrs with my L-Pro filter and split the channels in APP for my RGB channels. The rest was all with my dual narrowband filter, which I used APP to extract the Ha & OIII channels and then combine using the RGBHOO algorithm to create this image. I'm playing with some other versions of this image, so if I get something I like, I'll post it as a different image.

I'd really like to figure out how to make my stars tighter, so if you're willing to share your "secrets" with me on how to do this, I'm open to listen!

Thanks for looking!

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.
