Always curious about abbreviations... so I had to look up CLS. City light suppression. Maybe everyone else knew but me!

[@LateNightAstronomy]

You actually just taught me something. I knew about the wavelengths it blocks but never thought about the abbreviation. Thanks for sharing!

[@rcuevasvidea]

An excellent video. I have SVBONY CLS clip filter too and my images has improveded a lot.

[@bullthrush]

Great photos demonstrating the filters. I have a UHC filter coming for Christmas. I've been using a #15 yellow filter for viewing Jupiter and Saturn this month.

[@LateNightAstronomy]

Thank you. I thought about including color filters in the video but decided to just stick with light pollution filters.

[@gregerianne3880]

Thanks so much for all the great information on your channel! Everything is very well done and thought out, understandable, and clear. I wanted to mention that for those of us who are being more affected by LED light pollution each year, there are some filters that can eliminate some LED light as well as the older sources of light pollution (Na, Hg lights). I just purchased an IDAS LPS-D3 clip in filter for my new Canon SL3 and I'm anxious to try it out. (I'm also anxious to get ONE good night to use my new DSLR! The weather's been very frustrating lately.) Hopefully, the results using the D3 filter will justify the expense. Thought I'd mention these types of filters since LED lights seem to be gradually replacing the older lights in city environments. Thanks again for all of your great videos and the terrific information you give us!

[@LateNightAstronomy]

It's very nice of you to say that and to share that wonderful information on new types of filters for LED light pollution. Please stop back by and let me know how that new filter works out for you! Take care and clear skies

[@ronrotunno522]

I really enjoyed the video. Very clear and informative (as usual). I use an Astronomik Ha filter which is great for blocking out LP and moonlight. It’s a little more of a challenge to achieve initial focus but if you whack the ISO up high enough and focus at F2 (on the Rokinon 135 for example) it’s not a problem. With this set up I can shoot 3-4 minutes in Bortle 6 skies and really increase the SNR, shoot at more moderate ISO’s etc. Thanks again.

[@LateNightAstronomy]

That Ha filter comes highly recommended from many. Keep up with the great work with your imaging!

[@paigebradley2490]

[@PagyBio]

Thanks for reviewing Svbony filters. Imho is a very honest cost-effective brand

[@LateNightAstronomy]

I agree! They have been nice to work with but more importantly I've enjoyed using their products.

[@buddyhenson2559]

Thank you for always making great videos that even newbies in the hobby, like me can appreciate and understand. I would really like to get a DSLR camera for taking photos. I would not be able to go all in with something super expensive, but starting out, what are the characteristics that are most important when buying a dslr camera? Also, I assume there are devices that allow you to attach a camera of that size to a telescope, similar to what I use with iPhone? Again, thanks for a great channel.

[@LateNightAstronomy]

Thanks and good questions. I would suggest you look for a used Canon or Nikon DSLR. The SL2 I use is probably pretty affordable right now on e bay. I would suggest looking for a DSLR with a cropped sensor and a zoom lens to get you started with star trails and some of the basics of imaging the night sky. Check out a video I did on DSLR astrophotography a few months back to get an idea of some of the basic settings. I would suggest not worrying about connecting it to a telescope at first. Just work it on a tripod.

[@ridleyroid9060]

Thank you for this video. Where I live, getting a drivers license is incredibly difficult, and also incredibly dangerous to really just go out with my telescope anywhere away from my house during night.

[@LateNightAstronomy]

I hope these solutions help you out a bit!

[@ellis2888]

I live in Puerto Rico there is no where to go where there's no light pollution. Drove over 2 hours to get to some recommended place by the astronomy club but i could still feel the light in my sensores.

[@parthd714]

This video is GREAT, I used to think light pollution filters just magically make your sky a bortle , now its clear what their purpose and working is. BTW can you explain what happens to image when focal length is same, eyepiece f is same and therefore the magnification is same but the aperture are different meaning same magnification but different f ratio, will the same image be more resolved? Or the AFOV will change?

[@LateNightAstronomy]

Thanks for your comment. I'm honestly not too sure regarding your question. Adding aperture for visual observing will let in more light and under ideal conditions will increase detail is my best guess. It also could have an impact on what eyepiece you buy and use depending on what the F-ratio is.

[@TheSamBaltazar]

Thanks for another informative video. May I know what is your experience when using the UHC filter for galaxies and other DSOs that are not nebulae?

[@LateNightAstronomy]

I have found them less effective on galaxies. For those in particular nothing can beat a darker sky.

[@TheSamBaltazar]

​@@LateNightAstronomyThanks, Michael! Looking forward to more useful videos and guides. 😊

[@kobiorama]

Thanks! I just ordered the UHC filter, for a canon 1200D full spectrum. I plan to use it under Bortle 5(6) skies. Do you see any difference between CLS and UHC? Is there an added benefit to capuring the milky way and not DSO with them? Thanks again for a comprehensive review and I'd really like to see a post processing video which takes into account the UHC filter.

[@LateNightAstronomy]

Good question! I only currently own the CLS filter for astrophotography but enjoy the UHC & O-III filter a good bit for visual observing. What are you planning to image first with it?

[@kobiorama]

@@LateNightAstronomy I'm planning to utilize primariliy my Samyang 135F2 with it, so probably the heart and soul, maybe Andromeda, stuff like that. I also have a 12mm F2.8 and a 24 1.4 which can use for wide field (milky way) but as this is not the season, it will have to wait. Any suggestions would be welcome for a first time DSO shooter (with tracking mount)

[@LateNightAstronomy]

@@kobiorama I've got a video coming out on Tuesday covering the Best Deep Sky objects for the Fall Sky. Heart and Soul is on the list and will work out well with a light pollution filter!!!

[@georgedicker9789]

Hi, thanks for the video. I've got the svbony cls filter with a dedicated astrophotography camera. I have noticed it decreases the brightest of the whole image including the nebulae. Is there an amount I'm meant to increase my exposure time by when using this filter? Thabks for your help

[@LateNightAstronomy]

Good question. This will decresease the brigthness of everything but hopefully the light pollution more than the target you are imaging. I've found that on certain targets, mainly nebulas and supernovas, this filter helps to increase my signal to noise ration. Allowing me to take a 45 second exposure versus perhaps a 15 second one from where I live. What type of post editing software are you using to extract light pollution?

[@AmatureAstronomer]

I live under Bortle 6 sky, when the oil refinery 1.5 miles from my house is not in operation. Being house bound, I cannot travel to dark skies. I live stack in SharpCap and I do no post processing, at all. I have tried a number of filters and found that the 2" SvBony CLS filter allows me to photograph targets such as the Heart Nebula much, much, much better than just a ICE Lipo filter, the SvBony UHC filter or no filter with my asi294 cooled camera However, the SvBony 2" CLS filter produces little halos around bright stars and seems to block blue light. The Pleiades, for instance shows dark gray nebulousity, instead of blue. Odd. Anybody know why?

[@LateNightAstronomy]

You and I have had a similar experience with the Svbony CLS filter and have imaged similar targets. Does the dark gray of the pleiades turn blue when you color correct and adjust saturation in post processing?

[@GreenScreenBartender]

For someone not interested in photography, just stargazing, would you recommend a UHC or CLS filter?

[@LateNightAstronomy]

For visual astronomy I have enjoyed using an O-III filter to observe super nova remnants. I don't use it all the time, but to eat through some light pollution it helps on certain objects.

[@Thermozilla317_editzyt]

hey sir can i use semi apo filter on dslr 200d with astromaster 130eq with light polluation

[@LateNightAstronomy]

Who makes it. I believe you can. Is it the one from Baader?

[@MrGeert1972]

Why not the Optolong L pro? That’s a broadband filter that can be used on lots of targets.

[@LateNightAstronomy]

I have read great things about that filter but it's a bit out of my price range at this point. Is that one that you enjoy using?

[@MrGeert1972]

@@LateNightAstronomy not yet it’s on my wishlist. Have seen some videos about it and looks promising. I will get it together with the redcat 51. And indeed they are not cheap.

[@klttrll]

Do you have any recommended brands for the visual filters?

[@LateNightAstronomy]

I have had good experience with the Zhumell line of visual filters, if those are still made. It should be linked in the description of the video. I own the O-III and UCH filter from that set.

[@xrvgamers1189]

Are light pollution filters useful for visual observations? I have read that they help with Nebulae so curious which objects would be visible with filters that can't be seen before.

[@LateNightAstronomy]

The O-III filter for something like the Veil Nebula was a game changer for me. For more general use, I would suggest a UHC filter like the one linked in the description of the video.

[@xrvgamers1189]

Apologies for the late reply. Thanks for the info on Veil nebula. Do north american, pelican, california nebula also become visibile with these filters? Just naming these targets since they seem to be at good observing positions in the sky. Would love to know if you have any other recommendations to try out with these filters. Many, many thanks!

[@LateNightAstronomy]

@@xrvgamers1189 Yes, give those a try as well. My CLS light pollution filter for AstroPhotography did wonders on the North American Nebula.

[@xrvgamers1189]

@@LateNightAstronomy thanks! Will try them out.

[@xrvgamers1189]

Looks like Zhumell 1.25" High Performance O-III Telescope Filter given in the video description has been discontinued. Do you have any other recommendations for the O-III filters?

[@pierspinelli8352]

Hello, what app did you use to look out for the objects in the sky?

[@LateNightAstronomy]

It is SkySafari 7. My favorite astronomy app. I've got a video review of it on the channel if you are interetsed!

[@seebass7]

what Bortle Class is your sky?

[@seebass7]

ahh nevermind, you're Bortle 5

[@MountainFisher]

I bought a UHC filter and it made the views worse. I live in Bortle 6-7 skies was looking at M1, Crab Nebula with a 9mm Orthoscopic filter at 82x and I could make it out and put in a 10mm Ortho 75x with the Optolong UHC Nebula filter and M1 disappeared. I put the filter in the 9mm and same thing. Everything I looked at was dimmer, no nebulosity whatsoever. I gave it 2 stars because it's good for the Moon and Venus.

[@LateNightAstronomy]

The O-III has been the best for my visual observing but only on targets like the Veil Nebula. Thanks for your thoughts and keep up the great observing!

[@MountainFisher]

@@LateNightAstronomy Everyone told me to get the UHC Neb filter and as far as I'm concerned I wasted $55. Although it does dim the waning half Moon and Venus seems to look better with the 2.25x Barlow on the 6mm Orthoscopic with a 281x view. It truly cuts down glare and Venus' cloud seems to have a bit of definition, seems. 🙂

They can't be very effective if you've needed to try so many so I don't think I'll bother and keep my money where it belongs

[@LateNightAstronomy]

They are no a one size fits all sollution but I have found theat the CLS filter has increased my exposure times and helped with my signal to noise ratio for astrophtography!
