Optolong L Quad Enhance Filter Review 

That Iris Nebula looks awesome, dark nebula have eluded me too. I was also fortunate to have Optolong reach out to me a while back and ask me to try out their L-Quad and I have found it to be great. I live under bortle 5 skies and it's been great. I shoot in colour though.

I have had the L Quad now for a few months and lovin' it. I have been using it with my EdgeHD8, 0.7 reducer, ASI294MC Pro on a CGX. It has really made a huge difference. Should I mention my backyard is Bortle 4. Don't hate me.🙂

Very cool! I have the l quad and was only using it on my OSC, but will need to try it on my qhy2868mm for sure now. I'm also shooting from bortel 7 skies.

Hmmm, I never thought of "Doubling Filters". I will certainly try adding the L-Quad ahead of the LRGB filters.. (I'm just up the road in Savannah with a Bortle 4.5 sky)

Everything in the world is good again when Stevie is making product videos! Great video. Who does your music, if you dont mind me asking.. A great many of us Astro people are also Guitar players. Just wondering.. Nice see you again Steve. Joe D

Always love your videos. Your style is hilarious and the information is great. I might just try that filter as it priced well. Wish they had an F2 version for it but for narrowband imaging I think your images speak for themselves. Best regards Luis from NY

una chulada de videos, muchas feliciades ¡¡ saludos desde mexico veracruz

Thanks for a great video! I think it makes sense that the quad has better contrast and less gradients, as it let’s less light through in general. You clearly demonstrated that :) But how about retaining relevant colors? What is it cutting out compared to the Pro? Do stars retain their “real” colors?

Good afternoon, I have a question, when you are photographing with the Ha, SII or OIII, do you also have the L Quad or L enhance filter in the coma corrector? Thanks

can you tell us what is the benefit of using these filters with a mono camera stacked up with narrow filter?

I don't know why Optolong can't make filters for Nikon cameras.

New mount?? 😎

Why are you showing us the images inverted from each other by 180 degrees?
