Testing a NEW Filter on the Triangulum Galaxy (Optolong L-Quad Enhance)
Вставка
- Опубліковано 1 лип 2024
- In this video, I'll be testing the imaging capabilities of the Optolong L-Quad Enhance filter, which is the successor to the Optolong L-Pro. I'll be photographing the Triangulum Galaxy to see what details it can pull out, especially the Hydrogen Alpha parts. The Triangulum Galaxy (Messier 33) is a spiral galaxy located in the constellation of Triangulum, at a distance of 2.73 million light-years away from Earth.

![[NEW] First Look at the Optolong L-ULTIMATE Filter](/img/n.gif)
Been very back and forth on this filter. It doesn’t quite do want I want it to, however it does improve from no filter. Terrific job as always, also the music makes me want to relisten to some of Nujabes old works
Antlia also has their version of a quad band filter that you can use for a comparison if needed. Also, Nujabes is one of my favorite lo-fi artists when I discovered him watching Samurai Champloo! He was one of the greats, and gone way too soon.
I’ll check out that filter, thank you. Also, man, Samurai Champloo was such a good show
Just came across your channel. Well done video and image.
Nice picture. Keep up the good work. 👍🏻
Adam Block showed a cool PixInsight tutorial that included subtraction of R channel from H-alpha to increase contrast of nebular knots in M33. But I have to say, your OSC of M33 rocks. I got rid of my radian quad, and have been using NBZ. May give this optolong quad Enhance a second look now!❤
Very well presented video Kwasi! I glad you managed to get 4 hours of integration time on M33 considering your problems with your mount.
The final image is beautiful the new filter is definitely a keeper.
All the best in the New Year.
Thank you, and I wish you all the best in 2024 as well!
Hi Kwasi,
I too have the Orion EON 130 and LOVE it. And, I too have just acquired the Optolong L-Quad Enhance Filter. You weren't kidding about it pulling out the Ha regions in that galaxy... awesome. Well, since my filter arrived, yep, so did the clouds and rain but tonight will be clear and I am anxious to put it to the test. It's amazing how far along these filters have come in just a few short years. This makes astrophotography possible for just about everyone. Great video.

So incredibly methodical. It's like every word and hand gesture is scripted to keep us astro kids on track, with cool quiet storm vibes to put us to sleep after a good, deep space imaging sesh.
Sir, I don’t know you. But the way you did this video is incredible. You are like the next MKBHD of astronomy.
Thanks for the kind remarks! Mr. Brownlee is an awesome creator, and I'm humbled that you think of me as him!
Superbe vidéo... Toujours intéressante à visionner .
Très belle photographie et belle réussite de M33 .
Merci à toi pour le partage ....👍👍👍👍👍
Bon ciel à toi et belles capture .

Great video! Keep it up!
Thanks Kwasi, another great video.
Great image! I always enjoy your content :)
Looks great!
Holy chill Batman! Love this relaxing channel! Also great info!
Very nice presentation.
You are amazing, i tried this one with 600mm on cropped no tracker. its not easy! Keep up the great work my friend :)
Hi Kwasi
I take this filter seriously for my future astrophotographies !
Thank you for sharing.
Very helpful and informative. Thank you and clear skies and have a super holiday season
Thanks for watching, and I wish you and yours Happy Holidays as well!
Hi Kwasi! Greetings from Germany! Great video! As I am also sitting a light polluted suburb next to Frankfurt with its huge light dome I am also thinking getting any filter to overcome that downsides of my location. What you have achieved using the L-Quad definately moves it very far up in the list of candidates to afford.
Well done. I see a lot of Ha detail.
Great presentation. Thank you for the info. The price point on the Optolong LQE isn't too bad. I'll have to check it out.
Nice picture.
Hi Kwasi, Just want to say I realy like you videos.
Much appreciated Rob! Thanks for watching!
A very informative & enjoyable video Kwasi! Thanks!👍Your image turned out great!👍Two items from me:
(1) A question: What is the sky quality (Bortle rating) there?
(2) FYI, the new LED streetlights emit a continuous spectrum, with a significant peak that covers quite a large portion of the blue part of the spectrum. If a broadband filter avoids transmitting at wavelengths close to an LED source's peak in blue, then the filter can mitigate the effects of LED-related light pollution to a degree, and improve the signal-to-noise ratio a decent amount. Unfortunately, there is no way to totally eliminate the impact of LED-related light pollution with filters, like what can be done with emission line spectra from Sodium & Mercury light sources.
Thanks for your kind remarks Derek!
(1): My area is under Bortle 7 skies. Optolong recommends that the LQE filter should be used with skies no higher that Bortle 7, so I barely made the cut, lol.
(2): Thanks for the clarification on that. When I was doing research on this, I still wasn't quite sure on the LED details, which is why I said "to my knowledge" in the video. A company called Antlia also has a quad band filter with a similar transmission graph to the LQE, and they claim to reduce the affects of LED lights so I did my basis off of that knowledge.
@@AstroParkAstrophotography My pleasure! Thanks for the answer to my question & the info regarding Optolong & Antlia filters! 👍
Hey Kwasi! My friend, may I ask, is it intentional, or do you just naturally never say "erm" as you're talking? The reason I ask is many years ago, I watched a documentary and a lady in the doc' was saying how she trained herself to never say "erm" during speeches and general everyday talking. I'm very curious my friend!
Forgive me for the second question Kwasi, but do you find you struggle to get the very faint Galactic outer arms in your urban area? I use the L-Pro, and I really struggle to capture enough Galactic outer arms in my data? That being said, I've only so far managed around 2.5 hours total integration on any of the bigger galaxies, M31, M33 and M101 respectively. Any advice or tips would be greatly appreciated my friend!
Thanks! Wes, Liverpool England ( Bortle 7 )
Hi Wes! I took a class in public speaking a while back, and over time I've trained myself to not use verbal pauses like "erm" or "um" when giving a talk. I do catch myself doing it every once in a while, which is fine. But when a person does it excessively, it comes off to the audience as if the person isn't quite sure what they're talking about. So I try to eliminate that or at least keep it to a minimum.
As for the faint detail in galaxies, the only advice I can offer is to increase your integration time. From my experience in the suburbs, I've gotten some good results with at least 6 hours (usually a 3 hour session over two nights), but your mileage may vary depending on the subject you're photographing.
@@AstroParkAstrophotography Hi again Kwasi!
Yes that makes a lot of sense Kwasi, I will start trying to talk in public that way myself! Thank You for explaining that my friend!
Yes I have wondered if my total integration was too low. Where I live, on a third floor flat, it is like a military operation getting all my heavy gear downstairs, all in one go, due to local thieves not allowing me to not worry sick my gear will be stolen if I'm not with it outside while going back upstairs for more gear! So it really is a tough job being outside for many hours in the cold! My average nights worth of total data is circa 2 hours, but spreading my data over multiple nights makes so much more sense, so that is what I will start doing Kwasi. Thank You so much for advice Kwasi, and clear skies from Liverpool England!
Wes.
