Ha Processing of the Horsehead Nebula - Still not totally satisfied!

Link: http://kurt-zeppetello.blogspot.com/2018/01/ha-processing-difficulties.html

I have recently been shooting Ha-images with a 7 nm Astronmik clip in filter and a Canon T3i/600D modified camera. The setup is attached to an Orion ED80 f/7.5 refractor. I have seen other Ha images with quite stunning results and my images look much less impressive. There is more detail than the RGB image I took but I was hopping for more.

Here is an image of 5.8 hrs.

I have other images using stacking raw exposures super pixel mode and stacking tiff exposures default settings which can be viewed on my website: http://kurt-zeppetello.blogspot.com/2018/01/ha-processing-difficulties.html

I have been converting all of my RGB images to tiff and then stacking them as I like the way the stars look better. The Tiff method does look smoother, however, stacking raw images seems to give more detail in Ha. It is just the crunchy look that I am concerned with. Not sure if it my camera or if my processing is horrible. I should mention my camera is a 5-year old work horse and I plan on getting a new monochrome CMOS as soon as finances are available. If any one has any thoughts I would appreciate them.

I will combine this with RGB data to see if there is positive enhancement.

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.
