WHY. SO. SERIOUS??? I have another comparison for you using the Eastern Veil Nebula. Or what I like to call, Joker's Smile. This time, it is between the Optolong l-eNhance, and my go-to light pollution filter, IDAS LPS D2.
No filter is perfect, while I still think the IDAS LPS D2 filter is a great general purpose light pollution filter, I noticed that it is cutting off the blue/green color region. And I can confirm this when I used it on an unfinished project of M45 Pleiades, and I could hardly pick up any of the blue nebulosity. It has also been noted here on a few threads that the IDAS LPS D2 does indeed, cut out a lot of the blue hue.
On the other hand, while it's not a true narrowband, the Optolong l-eNhance still cuts out a lot of light and thus, it would prove challenging as a beginner when you are just taking test exposures and framing your target. Note the adjustment in ISO setting, so you can estimate that the l-eNhance restricts almost 4x amount of light through.
I have been framing my targets with D2 and then switching over to l-eNhance when I am ready to start the session. I love this l-eNhance filter, and the natural color it is able to help me capture.
For both of these images, I stretched the image, and used a luminosity layer to bring out the contrast and nebulosity. But neither has had any saturation/hue adjustment. I prefer to retain as natural of colors as I can.
