After a lot of rethinking this, I am representing my Sh2-135 with more balanced reds and hopefully the details in the brighter parts of the nebula retained (vs. completely blown out).

My thoughts are the H-alpha is an imagers print where as this color rendition is an observer’s image engaging the viewer to explore the image. 

Very nice 👍🏻

I like the second version better.  I like to see the darker holes in the nebula.

So, Voyager it is....I like it! But, I still would have preferred One Ten Soldier (as a pun on One Tin Soldier from Billy Jack soundtrack), but I guess you're not ready to ride off into the sunset, at least not handcuffed in the back of a squad car.

Nice work Roland.

I noticed something in the image I've never noticed before in images of M27, and that's what seems to be a distinct jet coming from the central star at~4 o'clock , if that's indeed the central star.

Very nice!

Cudos to George and the AP tech support staff. After my failed attempt to connect a Lodestar X2 to my AP900HDA, which resulted in shorting out both the Lodestar and my hand controller, I was afraid that my mount was ruined, since there were so few of them sold. I sent it to AP, and the crew there was able to repair it and restore it to working condition again. Since without guiding I was limited to 60 second exposures, I decided to see what I could get with that limitation, and imaged the Gamma Cygni Nebula with my Astro-modded 5DII and 500mm f/4L lens (125/500) using 60-second subs. I ended up with 300 subs at 60 seconds, for 5 hours of integration time, as well as an additional 55 subs at 30 seconds to blend back in to give smaller stars. Captured in my front yard South of Marquette, mid-Bortle 4.

After completing this project, I contacted George and he sent me a PDF on adjusting the gear mesh. While working through the adjustment, when I released the adjustment bolt the test knob immediately turned easier, so it apparently had gotten bumped in the past and was binding. After completing the adjustment, a subsequent test indicated that I can now do 3 minute subs unguided, which will make this mount much more useful. My 900HDA also came with an original SBIG ST-4 cooled camera and an SBIG guiding computer, which may extend the maximum exposure time even if it is a little awkward to use. I'll have to try that in the future.

Voyager is so fitting for such an optic. 🤗

Kon-Tiki (Thor Heyerdahl 1947) or Ra (1969) would have also fit.

Thanks for the process/progress report!!!
