The Optolong L-eXtreme Filter is INSANE! 

Find a girl who looks at you the same way Trevor looks at an Optolong L-eXtreme Filter.

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

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!

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!

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

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.

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

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

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!

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

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.

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!

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

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

Thanks Trevor... just ordered!! Exited.

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

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.

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!

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!

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.

Magical stuff Trevor!

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

Super cool!! Thanks for telling.

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

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!

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.

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.

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.

Yep I've had it in the mail as well

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

Love it! Keep up the good work

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

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

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

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

Great review. You’ve sold me

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

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

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

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

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!

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! :)

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!

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

Beautiful!

I much admit the thumbnail sold me!

I got this filter few weeks ago and I have to say: This filter in combination with the QHY268C (or BSI sensor cams in general) is absolutly kickass. You can see the outer most H-alpha parts of M27 after only 3 hours! BÄÄÄM! And if you make use of dithering for CFA drizzle, you get the resolution comparable to mono.

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

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?

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

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

What a time to be Alive, can't believe he said that in 2020

@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.....

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?

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...

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.

This is great no words....

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

Pretty cool 🔭

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

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 RU-vid..I wanna do what you do for a living too. So so bad.

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

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.

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

I like the enthusiasm! This video made me both excited and pissed (I just purchased the L-eNhance filter a month ago). Gah! I know as soon as I trade up to the L-eXtreme they'll come out with the "Ultra Extreme" or something.

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

and of course I just bought an enhance a couple weeks ago but really it does what I want.

Would the regular EOS R (not Ra) be a good fit?

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

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?

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!...

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?

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)

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!

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

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.

Love your videos! Btw what weather app do you recomend?

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.

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?)

Hey Trevor, well I couldn't wait after your first mention of this filter. Ordered it on Sunday and received it a few hours ago. Ofcourse it came with a lot of Cumulus Interuptus, so trying the filter out will have to wait a bit. Also, as I am one of those guys with an older DSLR I am very curious if your warning in this vid also applies to me (Canon 60D modded). If so, it might be the thing that pushes me over the edge to go for a dedicated astro camera too. Although I would have to go for a ZWO as I became an ASI Air (Pro) user recently.

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

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?

Thank you for the excellent review. Just one question, I live in a bortle 3 area, would this filter still be of benefit to me?

Very nice video, probably wotks with galaxies? O live in Borttle 9 City. Thanks in advance.

Amazing. I don't even have a telescope or equipment yet. It's on the list though.

Mine comes tomorrow!!! I think I peed myself a little after watching this!

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

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

One question... You said it's a perfect fit for a camera "dedicated" to astrophotography... So you would not suggest it for a "normal" DSLR? Or it would be a great addition anyway? It still will do its job on light pollution area as you said even for a low budget camera? Thank you in advance.

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

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

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

Trevor, is this filter parfocal to no filter or an IR/UV cut filter? When shooting narrow band, I usually focus unfiltered or with the cut filter, then swap the narrow band filter in before starting my data collection.

@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.

Will it work with a canon sl2?

So with the wider bandpass, would you say the L-enhance is better suited for a RASA? Or is the need for fast filters limited to mono narrowband only?

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

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.

How is the halo performance of l extreme in comparing with l enhance?

Wonder if the base Canon R will be good.
