The Optolong L-eXtreme Filter is INSANE!

Optolong L-eXtreme Filter: bit.ly/45YuQzs
Detailed Review: bit.ly/l-extreme-review
The Optolong L-eXtreme filter is now being used in backyards across the globe, which is great news for those that take astrophotography images in heavy light pollution.
This astrophotography filter features even narrower bandpasses than last year's L-eNhance, making it perfect for nebula photography from the city.
The Optolong L-eXtreme filter isolates the H-alpha (Ha), and Oxygen III (OIII) at 7nm exclusively. Unlike the previous L-eNhance, the eXtreme does not include a bandpass for H-Beta (Hb).
Thank you for watching, and clear skies!

I'm getting it for Tokyo astrophotography - awesome Helix!

[@dann.3943]

From my 5 year old son: I wish we could go back to NEAF and talk about space. And I want you to teach me to be like you. You're one of the greatest people in the whole world!

[@deviningram6814]

I dont take astrophotography photos, yet I watch your videos each time. So cool to see such a passionate individual in their craft

[@avananana]

I've been doing astrophotography for about half a year or so now. And I recently got a Star Adventurer mount and a pretty big lens as my first real astrophotography setup. I had taken a few photos of Andromeda before but they never turned out well but boy, couldn't have imagined the results of actually having a good mount and a good lens. Expensive hobby with incredible results, mainly thanks to your videos keeping me interested and being educational at the same time.

[@emileparadis3581]

Wow! I was just looking to the L-eNhance and thinking this could be my next purchase, but this looks way more promising! Great video Trevor, I just love your passion!

[@michielvaganee3055]

Again an amazing video, you explain everything so clear !! Good work !!

[@michaeldavis2818]

Another great video Trevor! I've been using my L-eXtreme for about a month and am blown away by how much it improved this beginner's astro shots! I pre-ordered and it took about 3 months to get but it was well worth the wait. I'm still trying to figure out which DSO's this filter works best with and don't want to waste any of the precious clear sky nights we get here in Minnesota. Thanks again for your insight and passion!

[@NikonJax]

May finally have to pull the trigger on this :) Thanks Trevor!

[@PafMedic]

Wow..Thats Beautiful Trevor,Your Photos Are Just Amazing❤️🔭❤️

[@catchingphotons]

Thanks Trevor for sharing this info with us! As always a highly professional and informative video! Clear skies man!

[@shubhkarmansingh7319]

Your videos motivate me to keep trying till I get my first clear image. I m just a beginner who has invested in this hobby after watching your videos. Just waiting for my Star Adventurer. Thank you Trevor.

[@PeterK6502]

Yesterday, I made a purchase of that filter, and today I came across this video.

[@H.Despres]

Thanks Trevor... just ordered!! Exited.

[@wesleydonnelly2141]

My goodness i wouldn't even say this filter is expensive when you consider the narrowness of band pass and convenience! It's going for coppers compared to some filters i've seen! Amazing piece of kit and definitely something i'll be buying...Thanks Trevor! I share your excitement sir!

[@eyesoftexasskywatch]

Figures they come out with a better filter just after I bought the L-Enhanced! Oh well. Thanks for the info and the good review. Great images!

[@jessicaanne1987]

I've got this bad boy in the mail! Can't wait to give it a go!

[@combatwombat71]

I've had one a few weeks - upgraded from my L-eNhance which I sold on. So far so good! I actually managed to process up Hubble-pallet style on NGC7000 with my 294MCPro.

[@Bluembuna79]

Those are some awesome pictures. I'm a noob just got a used telescope as a gift couple weeks ago and I'm hooked. Tonight was the first time I ever saw Jupiter through a telescope! I can't believe I was able to find it and keep it in view, considering the first night I had a hard time getting the moon in view lol. Subscribed you have a really cool channel.

[@piotrjakuc6357]

That filter looks amazing! And all those awesome pics were with a colour camera too? You're making me jealous Trevor!

[@shivercanada]

I just got the 2" version with my first cool cam, the ASI533MC Pro but need an extension tube to try it out! Can't wait!

[@birreboi]

Very cool photo and looks like an amazing filter to use with the right camera.

[@RugbyLock2668]

Magical stuff Trevor!

[@AstroBlender]

I actually ordered one today. Your IG images convinced me to move on from the L-eNhance. 7nm dual-band filter is quite the optical engineering feat.

[@space9342]

AstroBackyard finishes in style with his optolong L -eXtreme Filter and pictures

[@dgasparotto]

Hey Trevor I just love these reviews! I am using the Optolong L-enhance 2” filter. The ability to filter out all light pollution in my backyard with Bortle 8 sky is mind blowing. BTW your podcasts with my buddy Steve are entertaining. How do get along with his humour? For that matter Dylan’s humour is a bit off the wall...crazy Auzzi’s. Thanks again!

[@ajlbeer]

Nice one man! Thanks for racing to the youtubez on our behalf :)

[@hsocommunity7209]

Super cool!! Thanks for telling.

[@India.stories]

Yes Trevor, thanks for the recommendation Am a noob but this filter got me looking at my first nebula shots instead of a washed out grey sky. Awesome Awesome Awesome

[@AstroFarsography]

Nice review there. Some stonking images though that Helix, boy no wonder you jumped out your seat 🤯

[@hkanderful]

OK, take my money! I live in a Bortle 6 area and it seems I have to order one of these. Think the filter will work just great with my WO Megrez 90 and 60Da.... Thank you so much for your great channel. All the best from Norway and clear skies

[@shackle7866]

Maybe don't rely on the filter. Just take a hour drive out of town if you can. Try get above the cities and then use the filter aswell

[@dekemp1986]

I think Optolong has to start cranking up the production after this ;) I just started using the L-enhance as my first 'narrow' band filter and that allready blew my mind on my oldish DSLR. probably not going to upgrade very soon as you mentioned a oldish DSLR could be a problem, thanks for the tip.

[@skye7690]

Great video. You said your best videos were with at F7, wow, was thinking it would be a lower f/ratio.

[@n-da-bunka2650]

Good review. Going for the L-extreme as first filter rather than trying the others. I have a cooled 183MC and have been trying to decide which filter for my Bortle 6 area near Charlotte, NC

[@marcelrahellucerneastrophoto]

Tomorrow i will get this amazing filter, really look forward to use it 💫☀️✨🤩

[@DennisCarmody]

I ordered one over the weekend and it's in the mail on the way to me. Can't wait!

[@VisibledarkAstro]

Great overview Trevor and nice work with the Helix. I've been using the L-eXtreme for a month or so now and have had some amazing results. When I first took some test exposures of the Dumbbell and Veil I was blown away. The QHY268C and L-eXtreme are a winning combo. I'm in awe of the leaps and bounds this hobby is taking with technology for capturing the wonders of the night sky.

[@davidjames4915]

QHY and Optolong must be right pleased with themselves for having both sent Trevor their products at the same time as the performance of each helps sell the other.

[@VisibledarkAstro]

@@davidjames4915 The two do work great together that is true. QHY sent me a QHY268C to try out and it's really been fantastic. Combined with the L-eXtreme they are a formidable combination in the astro market.

[@michal_king478]

I just got the clip cls filter and Im so happy I got it. It enables me to take images from my house under a bortle 8 sky instead of having to drive like 30 or 50 kilometers away. Ill probably get the l extreme, l enhance or the l pro later on

[@MelroyvandenBerg]

Love it! Keep up the good work

[@AstroQuest1]

Great Helix Trevor in that light glowing low southern sky. This filter is awesome for the right camera. I was wondering when something with narrower band passes was coming out or why it took so long. Also I think what you said about the older DSLR's and such was very important. I love my T3i but have had trouble looking for and framing objects using the 12nm clip-in - I can only imagine trying to find an object with a 7 nm band pass. Cheers

[@alanhat26]

I'm not at this level yet but great video and info and of course awesome pictures

[@RobinGrays]

I much admit the thumbnail sold me!

[@sacra2kx]

A couple of years later, here I am: "Trevor, you were right about that L-eXtreme Filter"

[@acidrtv]

Great review. You’ve sold me

[@chishioengi]

Trevor, you were RIGHT about that L-eXtreme filter. Seriously.

[@micnek]

Hi Trevor and thanks for an excellent channel! I wonder what kind of adapter you were using on QHY268 (rotational adapter on top of the filter-holder)? I recently purchased QHY268 and looking for a similar adapter. Thx a lot!

[@Sidecontrol1234]

Just ordered my L-extreme filter, when i saw that butterfly image I couldn't order it quick enough! lol

[@tichwykes]

Hi Trevor I've been watching your videos on your channel these past couple of weeks and your imaging skills are top notch. I've done a bit myself but never had the same level of success. I may look into these dual band filters sometime soon, my favorite targets are galaxies what sort of filter would you recommend to use with a osc camera or dslr to shoot those?

[@AstroPhotos]

That's just superb! You could just save the stacked image from DSS and upload straight to your insta, I bet most people (if any) wouldn't know that it hasn't been processed! Wow!

[@caracolr1]

Nice video Trevor, can i ask you how do you connect the RA to the Esprit? Thanks Clear Skies.

[@davidmontierth8258]

I just called Starizona and cancelled my backordered l-enahnce. Now looking for an l-extreme. Thanks Trevor!

[@RaysAstrophotography]

Optolong L-enhance filter is one of the best. That I figured it out. I heard this Xtremre is better one . Now I see the results. Good video and great Images!

[@Wombatzone31]

with the shots you did with the canon, what temps did your sensor come out at after each exposure? I ask this as I have just built a peltier cooler for my 200D and can get to 10 degrees celcus for my 5min exposures. Would this work well with a canon with cooling?

[@brod5352]

Just ordered mine. Looks like a 7-14 day back order. I hate waiting. But my ZWO Dual Band has been working pretty well for me. I just need a good storm to come through and put out the stupid fires messing with night sky. I'm out west and the smoke has been horrible. But were supposed to get some SNOW....yes I said it, SNOW....maybe Monday into Tuesday this coming week. I'm hoping this allows the crews to get ahead of the fire. Keeping my fingers crossed. ;o)

[@gomanastro]

Thanks for your passion and commitment: My question is what is the difference in using this filter vs the Triad on these same objects, using the same color cameras, in heavy light pollution? Both filters have very narrow bands, but am I wrong to assume the Triad would give more color/detail with the 2 extra bands? or do these extra bands also let in more light pollution---compared to the L-eXtreme? Your review of the Triad had me convinced to get it despite the price, and combine it with QHY268, Esprit 120mm for use Bortle 9 to get some decent shots....I really don't want to get both....does each have it's own purpose in your opinion?

[@astromiasto8651]

Hi Trevor, can I connect this 2” filter to flat61 on my zenithstar 61? If you’re to busy to answer, many thanks for what you doing! You inspiring so many people!...

[@astroadventures3559]

I got a T3i the other day with a sigma 100-300mm on bbn it for 100 bucks the other day. Thanks to you for always recommending it. I figured I can astro modifi it with the naked sensor mod myself and not have to make my T7i unusable for filmmaking for KZbin..I wanna do what you do for a living too. So so bad.

[@lousupino9236]

@astrobackyard -Great results...I'm going to have to add one of these to my filter quiver....now if only the smoked filled skies of Colorado would disappear.....

[@derekderek2570]

You have no idea...

[@dgasparotto]

Hey Trevor. Question. I have used the L- enhance filter with galaxies and although it does filter out some of the needed light I am wondering if the L-extreme, in filtering out H beta, would be too much for imaging galaxies?

[@georgepistikoudis]

Trevor, could this filter be used with mono ccd cameras to do Lrgb imaging from light polluted areas? (in combination with the red, green and blue filters?)

[@timeless_realm]

Beautiful!

[@50sKid]

Yep I've had it in the mail as well

[@johnholmes125]

Trev been following you for quite some time now, I had a deep sky image setup which I miss so much but due to injury it had to go!! So looking to use my Sony a7iii with my lenses and get a skywatcher az gti with a equatorial wedge for lightweight imaging so my main question is will the filter be able to enhance the red response in the stock a7iii I don’t want to get it modded as I use it as my main day camera!!! Thanks Trev

[@remihanscotte2485]

Hey Trevor, Do you thing I can shoot with this filter in front of Baader RCCI corrector + Baader off axis guider ? There will be enogh stars on guide cam sensor ? (Zwo asi 120mc)

[@DaPanda19]

I wish I could do Deep Space Astrophotography :( but I'm hoping to get something cool from my Canon RF 35mm 1.8 in Joshua Tree next month! I love your channel! :)

[@fiorenzomanganiello2853]

Hi, can you make a video with an example of workflow for this filter?

[@JRock4572001]

Go with the IDAS NBZ filter. Better quality and actually designed for fast optically systems. I got mine a couple of weeks ago and I love for my f/4 astrograph.

[@astrofenixsv]

Hello Trevor, a question can the filter be used in the zwo asi 533 mc pro (Color), my sky is class 4 bortle, quality 20.72 there are some led street lights I would like to know what filter could serve me. Greetings

[@astroadventures3559]

@AstroBackyard Hey trevor do you have a link for how to do a naked sensor mod to my T3i I just bought? I got it because you recommend it and I've seen what you could do with it. So I figured I can only increase my chances of good astro with the same camera.

[@johnnysager8899]

Looks awesome and I have a stupid question? Can you also use this for just visual observations??

[@stevel3o7]

Hello; looking for that camera adapter that allows you to use 2" filter with your dslr, thanks!

[@christophermeglino3790]

Hi Trevor! I started out with untracked astrophotography about a month ago with my eos rebel sl1. What filter do you think might benefit me the most, if any is worth getting? I’m planning on getting a star adventurer later this year as well. This filter seems a bit expensive, and I don’t know too much about different kinds of filters and stuff. I’m shooting from Brooklyn, NY which is Bortle 8-9.

[@chanceg1218]

what do you use to mount the filter to your camera? If I am using a Canon EOS RP (RF Lenses) what kind of adapter would I need to fit this filter? Thanks, and great video.

[@aaron_r.5743]

Hi Trevor, I have a question. If I'm tracking the milky way, what would be an acceptable amount of framed to stack? How long should I track it for? Also, what should I buy for a DSLR that avoids light pollution? I live in a b7 zone and I can't really do deep sky.

[@paulwright3799]

Astro Noob Question i have a Nikon D4 And D500 is there a drop in filter option like you use on the red cat as i use a 70-200 f2,8 at the moment and i cant find a slot int filter system anywhere thank for any help you can provide...

[@AliIzadiRad]

I wonder what was the focal length of your optic for taking the Helix planetary nebula? it was clear and it doesn't see cropped too much to me

[@bigone520]

Would this be OK with a asi183 one shot colour .. with a william optics 81gt

[@trevor3645]

Hi Trevor, I was wondering if the optolong L-Pro filter would be suitable for my class 4 sky, I do have significant light dome in the west?

[@divye.ruhela]

Using an EOS 1200d/ Rebel T5. Regarding the focusing issue while using the live view function, can't it be resolved by focusing via taking long exposures using APT/ NINA & the Bahtinov mask tool?

[@Steve_The_Ignorant_Astronomer]

Trevor , I have the L pro 2in filter but cant figure out something. I want to use a 2in. nose piece instead of the 1 1/4 that came with the camera but not sure what I need to get. Using a zwo 294 ... Please point me in the right direction .... Steve

[@richarddavies9060]

Would you use this filter as a replacement for the L-enhanced or in conjunction with? Are there better objects more suited for the L-enhanced over the extreme? I recently purchased the pro, enhanced and extreme to cover a wide variety of objects. Thank you, Richard

[@0815mkl]

For the focusing topic, can you just leave the filter out, focus and then put the filter back in? I should not change the focus, because it is flat and is just blocking light. Or is the extreme reduction to only a few wavelengths already kicking in the problem that different wavelengths need different focus?

[@Athiril]

How do you think it compares to the optolong UHC? I got the 2” UHC and jerryrigged it onto the front of camera lenses

[@AncalimeNL]

How did you get this linear data looking so good with this filter? I have the filter too, but the linear data is black with a few stars....

[@tonysauser7562]

How well would this work on unmodified Nikon z6 mirrorless? Thinking about getting a RedCat 51. I have a 12” lx600. Thanks

[@xandergreer]

hey trevor! quick question, would this work well with my full spectrum modified rebel t7?

[@williamwesley5078]

I like how that filter is easier to grab, with others u gotta u got to be more careful not to leave a finger print...so I would give it 2 Stars just for the design of the Filter let alone its mindblowing Quality and most important "Final Results". Awesome filter, thanks for showing us the goods... I've always loved the stars my hole life and when me and my wife watched you more and more are interest in the deep sky objects grew and grew... 2 days ago we got the Meade 127eq 5" Aperture with 1000mm focal length...I wanted to get an aperture of at least 5inches to really explore, I had a budget to not go over $200..so I got the best I could with with 200... So..I was wondering if you have any advice on what type of ccd camera and or filter i should get...i want to maximize hydrogen Alpha and do 6nm for Oxygenlll....and my budget I'm making for myself is round $100 I can spend, any advice would be appreciated...srry for this huge long message...

[@phmuller]

I just got mine, supposed to be raining next 2 weeks... Any reason for me to keep my L-enHance?

[@dutenait824]

Does anyone know If or when the EOS clip-filter version comes out? was so tempted to buy the l-enhance last year, but then this baby got anounced.

[@VinayKumar-yg5rf]

Hi, i watch your videos of deep sky i love all. I am new in AP and want suggestions from you can you please suggest what telescope i buy for capture galaxies nebulas. I have dslr 6d mark ii but confuse which telescope help me.

[@januszciechowskiphotograph7297]

Is there any way I could connect that filter with my EOS R 5 and use with canon lenses ?

[@coatman9294]

Hey Trevor, when you say "an older rebel" series, how old are you talking, as i have the Rebel T7i or EOS 800D (crica 2017 i believe) would this filter be useful for this Camera, as I am a bit far off from purchasing a dedicated astro camera. just curious as i am on the verge of buying one.

[@NoTrespassingHere]

Ive got an h alpha and light pollution filter witch affordable filter should i get next?

[@PlanetaryDefenseFoundation]

Help, I have the Askar FMA230 I'm having a hard time finding the correct H Alpha Narrow Band Filter. My camera I'm using is the ZWO Asi183MC.

[@gabrieldavidson4442]

Could you use this for the L channel on a CCD camera?

[@alexweinstein3041]

Recently purchased the L-eXtreme to replace my L-eNhance (I shoot from Manhattan, so any little bit of help is worth it...). Did you have any issues preprocessing the image? I am having serious trouble getting this to look at all presentable. I am using the same workflow I used with my eNhance, but my data is completely unusable. I am starting to think I have a defective unit, but I am wondering if you needed to change any settings since filter is so narrow at 7nm on both bands. Thanks!

[@giannispomonis]

Trevor please tell me, will the Optolong L-Xtreme fetch good results, if mounted in a filter drawer and shooting with an A7 SONY III FULL FRAME DSLR camera? I mean I have already ordered this filter, hoping for a good light pollution shield and a good signal of nebulas. Is the IR filter on most non modded DSLR's - as my SONY A7 III - blocking the capabilities of the Optolong L-Xtreme 2 inch filter?

[@AdirondackAstronomy]

Great review of this filter, just another toy to add to my wishlist. Also... you use DSS for stacking and PS for editing? I always figured you used PixInsight (or other similar astro software) for stacking and post processing. The last few images I've done I find stacking in DSS and then PI for post to work the best for me.

[@tomaltman9506]

I need this for Sony Alpha clip in, but can only find the Pro. Any advice?

[@CD-lc4ir]

Do any of these filters screw onto a dslr lens or do you need a special adapter and a telescope?
