This is a great, well researched review. I live near Seattle, under a bortle 7 sky. Just bought the Svbony CLS as it's the cheapest I could find and I'm still figuring out if this is a hobby I can get into. The filter arrived 5 days after I ordered it and right on the night I got it it started raining. We've had 2 semi clear nights in the month that I've had it and I don't think it'll get better soon. I guess I will have to wait till spring given that traveling is still not such a good idea. Bummer!

Great review! I have a couple of technical comments for you to consider. Since these are all thin film interference filters (thin film stacks of high and low index), their design is probably established with normal incident light. It was unclear if the stand you developed included a collimated light source. If not, you could have a large portion of the light at substantially non-normal angles. In that case, the optical thickness of each layer will be different and each filter design will behave differently (less transmission and wavelength isolation shifted). This could be a key contributor to your "as measured" results varying from the manufacturer's specification. You might want to attempt to collimate the light a bit (could even emulate the focal length of the lens you intend to use) and then see how the filters perform on your spectrometer.
@NebulaPhotos2 жыл бұрын
Yes, that is what added substantially to the cost of building the device. I bought my collimated tungsten lamp from Thor Labs. I could try to emulate my focal length by adding more lenses, but I don't think that should be necessary. From what I understand talking to others is that it's pretty normal for these filters to be not completely 'in spec'. The transmission charts they send are not that particular filter measured, but rather an ideal filter. Most filter manufacturers don't state how much variance is acceptable. All that said, I didn't see really anything out of the ordinary in the real world imaging tests which is what really matters more to me.
@BoomBoom3872 жыл бұрын
@@NebulaPhotos If you could draw a "idealized" filter spectrum showing transmission by wavelength, what would it look like? Which specific wavelengths would you want to block? There are a few companies out there making more advanced optical thin film products for fluorescence microscopy, telecom applications, etc. Like the filters you reviewed, these can be bandpass, multi band pass in nature or even designed for specific slope shapes over the entire visible spectrum. They typically have ion beam or magnetron sputtering systems with advanced optical endpoint control to deliver higher transmission >95% and very steep and deep optical isolation OD5 or even OD6 performance. It would be an interesting design challenge to see if a manufacturable design solution could be created for your "ideal" spectral response.

Thanks for carrying out such a thorough series of tests and image captures! One major issue I have with your results however is that you actually combined two filters in some of the tests. I would have preferred you not to have confused the results with the pairings with the Astronomik L-2 in each case. The headline 'Light Pollution Filter SHOOTOUT' should be just that or else modified to include 'in combination sometimes with an Astronomik L-2'! And what about combinations with the Astronomik L-1 or L-3?

Hi Ed, There seems to be a misunderstanding here. To be clear: I didn't double up filters in any of these image captures. In the QHY tests, I only used the L-2 as the control filter for comparison to the other filters. I used an L-2 rather than a bare sensor because in real-life shooting I would never suggest someone shoots deep sky with the QHY168C without some kind of IR-block. Again, all the tests were single filter tests. Sorry for the confusion, Nico

I’m just about to send my DSLR out to be for spectrum modified. From what I’m gathering, the benefit of doing this is to get the IR light that is normally cut out on a stock camera. Wouldn’t a filter like the L2 also do the same as the built-in DSLR IR filter and block out the IR? I thought IR passing through was what I want for nebula. Thanks and great video!
@NebulaPhotos4 жыл бұрын
Hi Christopher, Stock DSLRs often have a very aggressive IR-Cut filter that actually cuts well in to "the visible spectrum" making red nebulae less bright (e.g. pass the Ha line at 35% transmission). Now what is a bit confusing is what we normally call "the visible spectrum" is 400-700nm, but humans can't really see much past 650nm. Ha is at 656nm and SII is at 672nm. These are the main spectral emission lines we want for nebulae, especially the Ha. They are both deep red. We are typically not interested in picking up the infrared (IR) in amateur astrophotography, and due to the way optics work passing the infrared will actually result in star bloat typically because most lenses can't focus on the infrared and the visible light spectrum at the same time. So the reason to use an "Astronomik L2" or other UV/IR cut filter with a full spectrum camera is to block the IR, but it still passes the Ha and SII (nebula emission lines). If you do go "full spectrum" with your mod, you will want to use a UV/IR cut filter too. Really the only reason to go "full spectrum" over an "ha mod" is if you want to shoot IR photography with an IR pass filter either during the day or for planets with a telescope. More on these topics in my intro to filters video: kzbin.info/www/bejne/r6SQY2uwadaHj9k Clear skies, Nico

@NebulaPhotos4 жыл бұрын
The duo narrowband filters are more expensive, but will be more effective at blocking light pollution and bringing out emission nebulae by increasing contrast. The downside is you won't get accurate star color with those. I probably wound't go as far as recommending SHO narrowband filters for DSLR/mirrorless because at that point I think the money would be better spent on an upgrade to a dedicated astronomy camera, but there are pros/cons there too (laptop needed, power considerations, etc.) So, all I can say in the end is "it's complicated" and really depends on your goals/desires/budget.

@NebulaPhotos4 жыл бұрын
More total exposure time is always better! NA Nebula is a tough object with a stock DSLR due to it being a dim, diffuse object that mostly shines in Ha (656nm) where many stock DSLRs are not particularly sensitive. To know if 20s, f/2.8, ISO800 is the right sub-exposure time, use the 1/4 histogram rule: take a test exposure, go to playback and hit the INFO button until you see a histogram, the peak of that histogram should be hitting about 1/4 over from the left. Adjust ISO or shutter speed until it is.

And, for example, if you look at Optolong’s page on the L-Pro, they position it as an LP filter as opposed to a nebula filter. www.optolong.com/cms/document/detail/id/13.html The idea is to reduce sky glow and light pollution from high pressure sodium and mercury vapour street lighting as well as suppressing blue in LED lighting. The L-Enhance and L-Extreme, on the other hand, are intended as nebula filters.

@@Mike__G Maybe this is an EAA vs. my style of astrophotography thing. I've tried LP filters on full spectrum objects like star clusters, reflection nebula, and galaxies, and never liked the results compared to shooting equal integration time without filter. If you look at the final set of crops here (QHY168c, Bortle 9): www.astrofilters.com/2020/10/15/light-pollution-filter-shootout/ you can see compared to no filter the L-Pro is really killing the blue channel. The Baader does better because it doesn't have that blue notch. There is no filter truly effective against modern LED streetlamps because they are broad spectrum like daylight, at least the ones I've measured in my neighborhood. I know a few cities have petitioned to get special 3200K LEDs put in. Wish that was the case where I live.

There are two major options for using filters with lenses. The best option if one is made for your camera is a clip-in filter. This clips in to the body of the camera and then you can attach any lens. The other option is to use a standard 2" filter like I show in the video and use step up or step down filter rings to go from the front diameter of your lens to the filter thread of the 2" filter (48mm).This is less desirable because if the front diameter of your lens is wider then 48mm so you are using a series of step down rings that cause vignetting that you will probably need to crop out from the final picture making only the center of the frame usable.

I own the Astronimik CLS and the Baader Neodynium and found very similar results to you in my bortle 5 region in Monroe, CT. I purchased the CLS first but was unhappy with the colors and more apparent noise that I got with it so I went with the Baader. I really don't use either much since I do most imaging with a monochrome camera, however, I now have an ASI 294MC Pro to be used with a new setup (once it arrives) so I will be using the Baader a lot more. I also purchased the IDAS NBZ for Ha and OIII imaging as well. - Cheers Kurt

Thanks Kurt. Yeah the Baader gives nice colors, and is very similar to the Optolong L-Pro. If I was doing much OSC work with moderate light pollution that is what I'd use too.

Man this is a great review. Really breaks it down in detail. Personally I thought the Optolong L-Pro was the best optically. And the SVBONY was close enough to the others that it’s price makes it the best if you’re on a budget.

Why do the images with filters look more graini or is it just my eyes
@RetiredMillennial3 жыл бұрын
Very scientific, nice job. Although I probably like the filters in the opposite order but that's probably why there are so many opinions on this because it is subjective pretty much especially if you are not an expert in it.
@NebulaPhotos3 жыл бұрын
Yep, I'd say in the end, when considering purchasing a LP filter, it really just comes down to: do you like how it affects the image? Which is mostly a subjective assessment

I appreciate the work you put in. I know that must have been exhausting. I got the l-pro but have not had a chance to play with it. My camera just got modified and I’m waiting to get it back. I’m under bortle 6-7 so I’m eagerly waiting clear skies. Thanks for your efforts.

Great review, very nice! Keep it up! A small feedback for your website: It would be awesome if you could add a slider to compare the before (without) and after (with) picture using the filter, because you already have all the data. Also at the first moment I found it a little bit confusing, that in the description of the pictures there is no note that a filter is used. Especially because in the Video you compared the picture taken with a filter to the picture without.
@NebulaPhotos3 жыл бұрын
Thanks for the feedback. I don't know how to do the slider thing, but I can look in to it. I did make this page for directly comparing the filters in the review against no filter: www.astrofilters.com/2020/10/15/light-pollution-filter-shootout/

Great review. Made me feel better about my astronomik cls. Was thinking about getting the l-pro for broadband, but do you think it would be all that different? From this review i wouldn't think so.

Finally, jk Nico! Great lesson!! I recently acquired a dedicated color camera and I use optolong-iv-ir for non nebule and l-enhance for nebula, I can see a big difference between this camera and dslr. I do not have any CLS filters and I am in bortle 6, do you think am good or do I need one? Oh am not planning on using dslr anymore only for like milky way or wide field when I can get to a better sky. Cheers Nico!!👍🤝
@NebulaPhotos4 жыл бұрын
Nope, you are all set with a UV-IR cut + an L-eNhance. Those are a perfect pair for dedicated astro camera. For DSLR milky way, no filter is always best in my opinion.

Excellent review and thoroughly done. I look forward to seeing further tests of more extreme dual band filters in the class of the Optolong L-Enhance, Astronomik UHC or Radian filters which OPT should be able to supply you, if they haven’t already. And keep in mind that it isn’t necessary to shoot only through a filter. Under darker skies shooting unfiltered and filtered images and blending them later gives you the best of both worlds: the natural star colours and more subtle tones of some nebulas along with the richest and greatest extent of faint red nebulosity. It isn’t either/or. Unless you are shooting under light polluted skies, then a filter and modified camera is essential. And in that case an even more extreme filter than what you tested here would likely be better. Clear skies!
@hoarsewhisperer41893 жыл бұрын
Personally, I thought there was a subtle improvement under Bortle 4 skies using the Lpro (best) and the Neodymium. Contrast was improved a little, but the stars were definitely tightened up and I didn't really notice any loss of star colour. The CLS filters were horrible. Really in the Bortle 9 you would be better with something like the L extreme. Anyway, good video, always good to see real life comparisons without hours of post processing.
