I image from my backyard in a Bortle 5, close to Bortle 4, area about 25-miles east of Seattle.  I've been using the L-Pro for Galaxy season and have been very pleased with the results.  such as these images of M94 and M106:

I recently acquired the Optolong L-eNhance to start working nebula and thought it would be interesting to compare the two.  This first image is of NGC 6888 The Crescent Nebula with the L-Pro:

And now the same nebula with the L-eNhance.  These were only a few days apart, and neither had any significant moonlight.

As you can see the L-eNhance really brought out a lot more detail and color, and even did so in slightly less time (25 minutes less).  I had considered the L-eXtreme and even the Radian Triad Quad-band, but came to realize those are really meant for heavy light polluted areas (the people reviewing them tend to live in very light polluted areas like Las Vegas) and I wanted something that would work with my HyperStar as well.  Pretty happy with the results, and thought I'd show a real comparison of the two.  I've also captured what is so far my favorite DSO image using the L-eNhance, M27 the Dumbbell Nebula:
