Hey Peter, I'm in downtown Bremerton and find that the L-Quad does not perform to my expectations from my back yard. I can shoot with the L-Extreme and results are superior. Keep up the good work!

Antlia triband is better. Second version will come out soon.

Not surprised. The problem with any of these broad band light pollution filters is that they only reject Hg and Na lines. With more and more lighting moving to broad band light sources like LEDs, they become pretty much useless

I am From Bortle 4-5 . I shoot this filter with Samyang 135 and 533mc pro. I have very good results both for broadband targets and Narrowband Target.

My backyard is Bortle 4. Some sky glow from 30k pop. cities nearby. I am using the quad (with ASI294MC Pro) with good results. Even during full moons +/- a few days. My two cents worth is too make the comparison with at least 5+ hours of time on a target. I suspect that is all that is needed for the quad's performance to pull away from the 'no filter' images. The quad has made a BIG difference in the quality of my images. I use either 3 or 5 minute subs for stacked totals from 5 hr. to 14 hrs.

Thanks! I'm not buying it, as I'm in bortle 8-9. Just watched a few Cuiv videos on filters. "Think " I'm getting an idea of which filters will give me good results. An honest evaluation like this is very helpful.

Need to test the filter with another camera, remember the 2600 has a IR/UV cut filter. I would like to know how the l-quad compares to the l-pro. 👍

I have the new Antlia quad and got the same results. Wish I didn’t waste the money on a quadband. Better off to just shoot with no filter at all. In a 4.5 zone love the Antlia ALT-P though. Worth every penny.

Non-narrowband light pollution filters are basically obsolete due to adoption of LED lighting, which has a more broadband emission spectrum than mercury or sodium lamps. (I googled about Bremerton and turned up a city document requiring installation of LED street lights...)

You probably should've also tested with a 533 as well, which doesn't have the uv/ir

For targets like Horsehead, I feel it's best to shoot no filter then add in HA from the L-extreme to do an HaRGB. Longer integration times definitely helps. I try to aim for a minimum of 6 hours to start and then go back and add additional data later.

Excellent video! I also find that filtered images have a red cast to the right side and a blue cast to the left. I see it in some of your examples. No one ever mentioned that in reviews and I wonder why that occurs? My tests are filtered and unfiltered agree with your results.

The transmission spectrum looks very close to the Orion skyglow imaging filter. Would work if everyone was still using sodium and mercury vapor lamps, but the ongoing 1:1 replacement with broad spectrum LED lighting makes these more useless over time.

Hi Peter! We have had pretty good experience from a Bortle 4 with the L-Quad vs No filter. My question for you is this: What filter do you set for the L-Quad in Pixinsight SPCC? I only recently got the software and would very much like to get your feedback!

The question is that 2600 mc pro already have uv IR cut filter build in Can we add any filter on top of that ? I got Optolong lquad and I’m not happy It turned out as you explain here it is much noise and sho much dust show . Thanks for a great video I wish I watched this video before I bought my filter.

What was total exposure time of each nebula? Amd what was each frame time exposure? Because for no filter it is possible you explode the frame if longer frames are taken

This maybe an obvious question to most, but I am starting out. Would these filters be strictly for refractor scopes and astro cameras? I have a mirrorless unmodified Canon R7 and a 70-200 2.8L. This is my current starting point. I'm wondering if I could use filters like this in Bortle 1/2 skies on something like an Ra? Also, would this filter be helpful in a Monochrome workflow using ASI2600MM?

Peter did you test the L-Ultimate filter? I guess the results would be even worse then the L-Quad Enhance since L-Ultimate is a more aggresive filter and lets in only 2 bands of 3nm bandwidth. I was excited about both of these but apparently you need darks skies anyways, so why waste good dark skies on filters.
