Messier 33 - Attempt 2 - Gear matters a lot!!

Almost exactly one year ago I shot this target with my Sigma 150-600mm telephoto lens and my Canon EOS RP mirrorless camera. Although I liked my image at the time, I never was fully satisfied with it. Due to using a unmodded camera, I was missing out on all the juicy Ha blobs in M33. As a result i'd say it looked almost quite bicolor.
Once I acquired my ZWO ASI 1600mm Pro, I always had the plan to reshoot M33 with Ha. So when clear skies finally came back in the last week, I focused all of my time on M33! I knew I'd see a improval in sharpness, but I didn't think it would be this drastic. It's save to say....I'm really loving my new newtonian telescope!! Below you can see the result of ~15hrs of RGB vs. ~5hrs OSC from my old setup.

Due to the unmodded nature of the Canon, this is not really a fair comparison. But to be honest, not like it ever was! So let's go one further:
M33 in HaRGB vs unmodded OSC data from my Canon EOS RP!

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.
