M33 is just bright enough to be seen with mere eyes from a moonless sky away from all lights. I've seen it from the SHSU Observatory. The background sky in this image is bright (and contrast relatively low) because all of my data was gathered from my backyard (community of 100,000 just south of a city of 100,000 (including suburbs)).
This image combines monochrome full-spectrum sub-frames with color sub-frames I took in 2012. I was glad to see the two data sets come together so well. The combined mono and color frames were matched in Registar then combined in Photoshop.

Wow! I'm always amazed by the images that you're able to get from your area despite the light pollution. It's weird to think that so much is visible with the right filters. I really like how you caught those star forming regions. Great job!
Thanks, Rory! Good filters get most of the credit. Also, so we had some very transparent nights a few weeks ago. Sometimes nature gives you her best chances.
