My Light Pollution Filters for Astrophotography

[@adammadi9109]

Finally, a straightforward video of what type of filters i need!!

[@Riley_tay]

Always enjoy your videos. I watch them over and over hoping one day I will know what I’m doing. Right now I’m trying to figure out an adapter where my filter can be used on my DSLR or a ZWO camera. I bought a 2” Optolong filter but there are a ton of different fittings and threads to learn and understand first. Trial and Error you one said is so right. Keep posting, you are awesome.

[@henryhird2021]

im going to be doing my first bit of astrophotography this weekend

[@AstroBackyard]

Congrats man - have fun

[@mintydrizzel25]

how is it coming along?

[@jesusgarcia-xj2mz]

@@mintydrizzel25 I started as well lol. I don't have the best lens and pieces for this but I've been using photoshop to bring in the stars! Honestly from my pictures I don't know if those are stars or maybe I did something to it, but there are thousands of them in the picture.. haa

[@JaknTV]

Good Video. Could u do a video about your very first astro pictures?

[@galacticadventurer6694]

I also live in red zone and thank you for this video. Those images look like shot from dark skies, now I can get a lp filter for the club. Thank you astro backyard

[@cristianosecci7729]

Thank you! I'm just about to decide which filter to buy to begin serious astrophotography with my Newton scope, and I found this video really helpful, especially because I also live in a heavily light polluted area.

[@AstroBackyard]

+Cristiano Secci Glad to hear that Cristiano! Thank you

[@boredwarlock5216]

Thanks for walking us through all these. You're the best!

[@akacagen]

I have just purchased my first Sky-Watcher Explorer 150P-DS OTA and Sky-Watcher EQM-35 PRO Go-To Modular Astronomy Mount. My first was a Sky-Watcher Explorer 130P SynScan AZ GOTO . Now I really want to get reward for the time that I am viewing by taking pictures of the things I don't or cannot see with the AZ setup. Why did you choose the camera you mentioned in the video? I currently have a Cannon 1200D. Besides all that. Your video was very inspiring and makes sense. Thank you.

[@Astrobiscuit]

Thx for the video... good info. I live in the heart of London UK. I've been imaging for about 2-3 years. I was wondering whether you'd tried a UHC filter with a DSLR on nebula from the city and whether it had been successful or not?

[@Astrobiscuit]

I actually did manage it from london zone 2 ... pretty good results too. Here's the vid i made about it. You might want to jump to part 3 to see the result kzbin.info/www/bejne/h4CWh2ytra2ei6c

[@shakeandbake9562]

Great info once again. I have learned so much from you, thank you!

[@shivercanada]

Thanks man! Got me a CLS filter from Ontario Telescopes, tested on the Orion Nebula were ok, the blue's just weren't there for some reason even after DSS stacking and taking Bias, Flats and Darks. A bit of a learning curve I suppose but seems to have helped otherwise. Good night tonight in our area for space peeking!

[@AstroBackyard]

+shivercanada Awesome man..Yes the blues are tough but you can bring them back in PS! It's clear and cold in Canada tonight!

[@anthonylanahan9902]

Great info as usual. I just got a 2” CLS since I live just outside Chicago. I know it won’t be a miracle cure, but I’m hoping it cuts down the post processing a bit and gives me more useable data. Unfortunately I’ve been waiting for a clear sky since. We’d be lucky to get more than a couple from October through November.

[@williamlee2769]

Best explanation I have seen on filter type and usage. Well done, thanks

[@ChrisTurchin]

Loving all your videos. Many thanks!

[@otoskope]

Thanks, very informative. I use a light pollution filter, and have a Ha+O3 filter that I haven't started using yet, so it is good to get an overall view. I especially appreciated the discussion on filters for modified DSLRs, since I have an unmodified Lumix GH4, and a full-spectrum modified Olympus E-PM2. I've just received a ZWO IR/UV block filter for it, which hopefully still lets through the Ha.We'll se how it goes.

[@oswaldbastable4139]

Thanks for that, great video for getting into filters. Just need to work out which narrowband frequencies I need 😀

[@astronomerathome]

I love my Baader M&S filter esp. with camera lenses. Gives you a very natural looking image as well as cutting down on the skyglow. You will always have a red tint with a modded cam. I don't see any with my unmodded cam. I also had a CLS filter for a while but I didn't like the bluish hue it gave. It was a pain to process out :(

[@toddnoseworthy1447]

Hey Trevor, Thanks for the info. I live in a Bortle 3 area that has LED lighting. I am using an unmodified canon DSLR right now. I have been considering the purchase of the new IDAS filter for LED lighting. A couple of questions: I read that using the filter tints the photos as you mentioned about some of your filters. How hard is that to remove in post? Secondly, living so far north, the Aurora can be in the sky often and can be very bright. They are of course largely green but some red sometimes. Would the IDAS filter have any effect on them, if not, is there a filter I could use instead? Finally, to keep costs down, I want to buy as few filters as possible. I am considering 2-inch filters, I think 1.25 would be too small for the full frame camera. Can they be inserted in the line between camera and telescope if I start using smaller sensor CCD / CMOS cameras that might have a 1.25" fitting? Can a two inch filter wheel be used in from of the smaller sensors? Thanks again for the great videos.

[@AlejandroMontiel]

Taking my first steps in astrophotography. A list of links to resellers of these filters would be of great help. Thanks for the great video

[@sorrycharlie3327]

This video was really helpful. Thank you.

[@mathieucarbou]

I was wondering if you tried or already saw the STC Astro-Multispectra Clip Filter in action ? From cyclopsoptics. It seems to be for cities but seems also to let far more wave lengths to pass through ?

[@banday78]

Great video, one thing .. u r going to use ur narrowband filters with hypercam color version .... arent u gonna miss out on whole lot of senstivity as opposed to monochrome cam on these filters?

[@GreenJeepAdventures]

Any tips for focusing while using a clip-in filter. I find it hard to see the Bahtinov diffraction spikes when I have a filter in place. Am I going to have to find focus without it, then remove the camera and install the filter, and hope when I put the camera back, that focus hasn't changed?

[@Sergeant_Nugget]

I see you talk about the clip in filter and the 2 inch mount filter, but what about the lens filter? I use Nikon and don't have a flattener. What about the camera lens dslr filter? I see Ohayo makes some fliter for astrophotography. Have you tried that type of filter?

[@ryanhogg6556]

Mate the narrowband filters would work good with the modified DSLR cam ? I modified it myself

[@gollondblack6247]

Would be great if you could show a set of pics taken with each filter to demonstrate the difference between them. Thanks.

[@tenzinshakya5654]

Hi Trevor I need your opinion on SVBONY SV503 Telescope, 102ED F7 Extra Low Dispersion Achromatic Refractor OTA. Should I buy it or they may have another option.

[@ronneilcamara5071]

Great video! I have a question. I'm interested only in milky way using dslr camera. I don't have a telescope. What are your thoughts on didymium filters? Can they block light pollution from street lamps?

[@aus_astro]

Hi Trevor, great video as always. With the Ha narrowband filter I see you are using the 12nm version. Have you used one of the tighter band ones, say a 7nm, before? I'm in similar light pollution range as you and tossing up between purchasing narrowband or really narrow band.

[@RobB_VK6ES]

Alternatives: The lower priced 12nm filters are the right choice for you, if you own a typical DSLR or a CCD camera with a high dark current! The 12nm filters should be the fist choice for cameras with an integrated guiding sensor, as you will have about twice as much stars compared to the 6nm filter.

[@FarmLapse]

I'm interested in the Hutech IDAS LPS-P2, but what I'm wondering, is it compatible for a full frame canon dslr and also what kind of "filter holding ring" would I need because I've been looking all over the internet and yet have found anything that really goes into the dslr like you've shown in the video.

[@ww2corsair]

So if I modify my camera and get rid of the IR Cut Filter and I get the CCD filter I am able to bring some colors back so I can shoot both RGB and Ha off of one camera? Because I am trying to figure out the logistics of how i am going to shoot both and combine them (i also watched your Ha and RGB combination video)

[@micharu570]

great video man! i have question: is sky watcher 150/750 eq 3-2 good telescope for begginers?

[@AlexSanchez-ke5ve]

Question, filters are using just for astrophotography? Or could they be used for observation too? I have a light pollution where I live, So doing observations is really hard. Regards.

[@tedwilliams3875]

I have been reading in many many places that UHC filters were best for Nebula's; especially The Orion Nebula. So you're saying that a CLS is better from your experience? I am looking to purchase the snap filters for my Canon 70D's. I like to purchase a variety of them to test out on my two cameras. I have a 1.25 UHC filter for my eyepieces and well The Orion Nebula looks great through it but never got around to taking photos since doing 1 to 3 second single exposures on DSO is like pointless with a DOB. I figured I would test it once I get my new Advanced VX8 in a couple weeks. I have some light pollution in my area. Its not too bad. In your opinion do you recommend certain filters for galaxies? Unfortunately the KZbin reviews are too lop sided to get a straight forward response. It just seems like too much contradictions. Since you have quite a few in your inventory; I figured I ask you. Thanks!

[@Mohammed-zo3qq]

Hi trevor, just wanna ask do you use the filters together or seperate for e.g the IDAS LIGHT POLLUTION SUPPRESSION and the Astronomik Ha 12nm filter, or do you take LPS for 20 images HA for 20 images and stack? forgive the ignorance

[@sukirtighosh9658]

Hi Trevor, thank you for your awesome insights on this channel, learnt a lot as I'm starting out in this topic. Instead of astro-modifying my camera (because I would still like to use it for daily use other than astrophotography), can I add any light pollution or other filters on a field flattener or in front of the tube on the T-ring adapter?

[@jasonpalmer2497]

Great imaging you do 👍👌❤️ I've just picked up 600d for astro wide field milkyway and telescope if I go full spectrum then use clip in filters uv/ir is this the correct filter for colour /rgb image. Many thanks j

[@grahamhgraham]

Great knowledge and insight. Thanks for sharing. Learned a lot.

[@lostindimcarcosa]

Hi Trevor, needing UV/IR block for naked sensor modded cameras only applies for refractors right? With my newtonian and the coma corrector installed I did not notice any deterioration shooting naked. I always shoot naked, rotf.... So the UV/IR block need is „only“ for refractors, right?

[@s3cr3tsqrl64]

Did I miss it or did you not cover it. Can I use any of these with an unmodded DSLR? Should I even bother?

[@noam8247]

Hi, I know I am a bit late but I was wondering if anyone could answer my question. So for the SkyTech CLS-CCD Broad band filter would that help to pull some detail even if you are just doing one exposure without any stacking. It would also be with an unmodded Canon DSLR. Sorry if this a really dumb or obvious question I am just brand new to astronomy and astrophotography, Thanks Have a good day/night.

[@kriss1313]

I like the background music... goes well with the topic :)

[@gunnarjensen5910]

I am using the Canon 7D, M50 and 5D mark II at the moment. Need a filter for light pollution 20km radius from city.. Using a sigma 20mm f/1.4 and canon 17-55mm f/2.8..

[@spiritas5372]

Do you have a suggestion for a filter for a less light polluted area? Say B4?

[@alessandrocernuzzi]

Ok, so, if I remove the IR filter from my camera I have to use an IR filter to avoid star bloat.... What am I missing here? :/ Thank for the great channel!!

[@erilocrown]

Is it better to use a crop sensor or full frame sensor camera?

[@astrofotoperu]

Hi Trevor! Thanks for this video, it helped a lot! I'm looking for a light pollution filter, for my ZWO 071 color cam. I've found a very interesting one which is made for color cameras, and will give only ha, hbeta, and oiii. It's called the Triad Filter, and it's made by OPT. What do you think about it? Should I go for a light pollution filter, or the triad?

[@EdwardRLyons]

Have you had any experience of HPS and LPS streetlights being replaced by broad spectrum, blue-white LEDs? If so, how much has it affected your ability to do astrophotography with the light-pollution filters? The streetlights here in Ireland (and many other parts of Europe) are being replaced by LEDs, and both the colour and severity of light pollution are changing as a result.

[@djchips]

This is excellent information, thank you. You mentioned that there are a lot of filters for Nikon - where would I find these?

[@prashaanthvenkatasubramani6805]

I NEED TO KNOW THIS TOO

[@ljastro2655]

Do you think you can do good pictures without a motorized mount?

[@Talespinner35]

Sorry to be so specific, but which would you choose between the Orion 5561 2" Skyglow Imaging Filter and the Celestron 2" UHC/LPR Light Pollution Filter? I am looking to use the filter primarily for imaging emission nebulae, using an unmodified Canon T3i with field flattener on a Z61 APO mounted on a SkyGuider Pro.

[@LD-kz3ms]

So the clip-in canon filters wont work with EF-S lenses?

[@bowen2307]

I've got a unmodded canon EOS 7d and 200mm telephoto lens, Which cls filter should I use? I read that CLS-CCD is only for modded cameras as there is extra IR blocking...

[@paulmannion2020]

Hello. Will the 2inch type fit on the end of a t ring adapter or a focal reducer?

[@flamingoboot8874]

i have a quick question.. i read your blog and im leaning towards the baader moon and skyglow for general purpose AP in a heavy LP area but i have an unmodded canon t6 and 80d.... will the ir cut be too heavy? should i go with the uhc instead... there are so many discussions on this topic.. i get overwhelmed.. most ppl use dedicated cameras and i havent reach that point yet, ive just stuck my toe in the water... i dont want to waste money either.. thanks...

[@lsauca87]

I’m looking to get into Astrophotography, you said your T3i is modified. How is it modified?

[@Robert08010]

DSLRs come with an IR cut filter which is bad for astrophotography but necessary for normal daylight use. He's mentioned in another video that you can remove the ir filter from a T3i pretty safely. I'm considering buying one dedicated for astrophotography so I can modify it and not have to worry about it. He has removed the IR filter from his but he also mentioned it's something you can do yourself on older DSLRs like the T3i.

[@viderocket]

Hello mate I have a full spectrum 650d canon, what is the best filter for astrophotography with very little light pollution area? thanks ben

[@Iithuanianboy]

Hey so I’m interested in a clip in filter for landscape astrophotgraphy. So I just wanted to clarify something, will a filter like the sky tech CLS ‘reveal’ stars to the camera that are otherwise washed out by light pollution? To give some context I leave in a suburb that’s at Bortle 7. And I can get to bortle 5-6 pretty easily.

[@briannichols118]

Great video--thanks. I've been a visual amateur for decades but new to astrophotography, slow learner on a steep part of the learning curve, for the last 4 decades living in an area that in hindsight has gone probably from Bortle 4 to Bortle 6 with access to Bortle 2 if I wanted to leave the back yard. Just stumbled across plate solving for framing dim images due to filtering (in my case mainly light pollution). Any thoughts on plate solving for framing via a favourite app? (Just subscribed to see if you already covered it). Also for worriers like me there is apparently a clip-in filter that will restore your modded DSLR for daylight use.

[@briannichols118]

No need to reply--found a remark you made in a video last year while illustrating the use of APT to control the setup, "Eat your heart out plate solving". Tells me everything I need to know :-)

[@ravichitwan]

By any chance did you catch the Jupiter and Venus conjunction? Please upload some content in regards to that, if available. Thanks buddy. Great channel.

[@aymanalfayez]

Is using these filters enough? instead of modifying the camera

[@KubiTheFox]

If anyone can answer. Do all the filters block the light pollution?

[@TheflickerofMotion]

Thanks Trevor, great info

[@Danny99uk]

Just started using a Baader Moon & Skyglow for imaging on a dslr. My usual starting point is 30sec ISO 3200. I used that for my 1st attempt but found i really couldnt see the Dumbbell Nebula. So i took my expose time up to 2 mins which gave me a better image but i had more images discarded through trailing. Would i be better to pump up the ISO when using this type of filter rather then relying on exposure time?

[@deanmindock5020]

I think Trevor mentioned going up as high as ISO 3200. Trailing stars might mean need for a guider and/or more time/accuracy spent on polar and star alignment. One think to do too is to make sure that the tripod is level, easiest to do before putting the mount head on the tripod.

[@gunnarjensen5910]

P.s. do I use automatic WB or daylight ?

[@vladantoniak9157]

Hey, where do you live? I live in NYC so you can understand how daunting it feels for me getting into astronomy.

[@algraham2469]

do your camera have to modified to used these filters

[@das250250]

If the sensor is capable of filtering out based on frequency of photons why cant this be done post production in raw images ? It is a shame we cannot ,or not that i am aware of , distinguish between a reflected photon light from atmosphere collision versus light that has come unhindered from space onto the lens

[@ImagingHeavens]

[@mythdusterds]

This was a useful video. I started to subscribe to your channel getting close to the Solar eclipse arround July 2017 to get ready for the solar eclipse in August 2017. I have recently purchased a hydrogen-Alpha night filter in September and got it after Hurrican came in the mail in September. I was currious what does it take a picture of the sun with a hydrogen-Alpha filter?

[@uwedeutermann1163]

Do not use the 7nm or 12nm Ha filters for the sun! A much narrower bandwidth is needed for that close star!

[@mythdusterds]

Uwe Deutermann What type of filter would you recommend for taking pictures of the sun? All I can find is Night Hydrogen-Alpha filter and paying over $1,000.00 for a camera lens built with a Hydrogen-Alpha filter in it at B&H

[@uwedeutermann1163]

Unfortunately the Ha filters to be able to observe the sun are that expensive. Their bandwidth is below an Angstrom, hence very difficult to produce. There are while light filters that are much cheaper, but observations in Ha are way more detailed and show very nicely solar ejections at the edge. I own a Coronado PST, which is pretty nice and costs around $500. Here a link to a good article about solar filters:www.astronomy.com/great-american-eclipse-2017/articles/2016/06/how-to-choose-a-hydrogen-alpha-filter

[@mythdusterds]

I was looking up Hydrogen Alpha equipment and found these 3 resources. I am not sure what the difference in a Prominence vs. a Chromosphere filter does. www.bhphotovideo.com/c/product/1302631-REG/daystar_filters_dsztnc_camera_quark_eyepiece_filter.html www.bhphotovideo.com/c/product/733957-REG/Coronado_SMT60DS_10_SolarMax_II_60_Double.html www.bhphotovideo.com/c/product/1302632-REG/daystar_filters_dsztnp_camera_quark_eyepiece_filter.html

[@uwedeutermann1163]

The difference between these 2 filters for a Nikon camera is how much it filters, you need a narrower filter for the Chromoshere. Not sure if I would pay that much money for observing the Chromosphere, I rather like the Prominences (if you do not know what Prominences and Chromosphere is just look it up on the Internet, there is a lot out there for this :-)). Nevertheless, any solar observation tool is expensive, unfortunately.

[@jonpenton9091]

I saw someone ask a similar question, but I haven’t seen a reply yet. After several years of ultra wide astrophotography (Milky Way nightscapes mainly) I finally just got a motorized mount, the MSM, hoping to improve the signal:noise ratio. I usually drive abt an hour to a class 3 site, so not too much light pollution interferes, but it would be nice to make some images closer to home, which ranges from classes 4-5+. Would all of these clip-in filters be effective for Ultra Wide night scapes, or are these mainly intended for close-ups of nebulae and Astro objects? Thanks for your time and find me on IG @jonpenton_photography

[@Black_Jesus3005]

Thanks

[@Robert08010]

I suppose if the objective is to capture nebula, it's not bad to have the stars reduced a little in brightness so they don't end up over exposed and washing the picture out.

[@Clydesdale2045]

As others have stated, what seems to be a contradiction is why it's good to get a modded camera with IR filter removed, but then one needs to buy an IR filter afterward as it's needed. Why mod the camera to remove the IR if it's needed? It sounds like buying a lawnmower, paying to have it modded to remove the bagger, and then having to buy a bagger for it because it's necessary. Why did you pay to have it modded to remove something necessary and has to be put back?

[@ruzzyshuya4832]

Yeah that's what I was thinking also. I was speaking to a sales advisor about a CLS Vs CLS-CCD and I asked that very questionable. Apparnelty it blocks the least amount of IR needed to prevent bloat but allows in the most light

[@grahamb9639]

[@dflash0]

Dude, I really like your informative videos and your presentation. But the more videos I watch from your channel, the more discouraged I get about astrophotography. All the gear you review is super expensive and unattainable by the regular person wanting to get into the hobby. Filters for $100+, $2000 telescopes, $600+ trackers. I understand you get a lot of products for free from vendors that send you stuff to review, but come on man!! Show realistic products that we can all afford.

[@nettyvoyager6336]

clip in filters are coming down in price now in the UK , your dollar is fucked i dont know what happened
