Wwau .. beautiful video ... if I may ask you ... in this video you add the astronomik h-alpha filter to the already modified SLR Sony or is it normal SLR and add the filter? What's happen of I use the h-alpha filter on a normal reflex? Thanks in Advance ..
After Alyn's passing, having this video pop up randomly in my feed is like he's saying hello from the stars. Magic. ❤
I saved this video to watch later as I am learning astrophotography. I have just watched it and I am keeping it for future reference as it's such a useful video. However I am deeply sddened to learn from you Alyn has passed away, that's so sad. The world is a brighter place for his passed on knowledge through YT. :)
Agree
They're super cool! This is just another fantastic technique to reveal what is hidden for the eye :D
I need a video explaining when you sleep!!!
I charge via USB
@@AlynWallace and a portable power bank lol

Great shots Alyn. I once heard from an Air B&B owner after we rented a couple of nights to shoot and showed her the images. She said, "I had no idea that all that stuff was up there". Keep bringing us "ALL THAT STUFF" and helping expand astrophotography the way you do.
Mannn...can't get enough of your intro..it's a masterpiece
Alyn "join me on this adventure into"....
Me *lacing up my boots "too right I will lad, bare with me a minute as I'm too fat to fasten both laces without a few quick breaths"
Proceeds to watch in awe
Excellent shots! I always wondered how a wide field shot would look with narrowband imaging.
Taking Flat frames is a life saver when you realize your sensor / glass Is just a mess
Amazing!👏👏👏 So this reminds us once again that there's so much more stuff in the night sky we can't see! Speaking of the final stacked image, I think most of the people can understand and appreciate the image more than a star trail one!😊 Since my friends always ask me what is that when I upload a star trail image!😂
If it was not for photographers like yourself, aspiring photographers like myself wouldn’t even know what to imagine when looking at the night sky. You have truly inspired me and helped me picture that perfect night sky.
I think to people that know what's actually possible with astro images it adds another dimension. But to photographers that don't usually shoot astro they tend to dismiss it as something that's not natural because we can't see it with the naked eye. It's usually landscape photographer's that have problems with it. But I ask them this "do you see the effects of a 10 stop filter?" That kind of gets the cogs moving a little.
I love astrophotography and for me personally this adds so much more to your picture. Incredibly jealous of this view
I second that
i think the h alpha is the most important step you can do in astrophotography. you go another level with it. go shoot the cygnus area, ngc 7000 and around sadr, deneb and enjoy the show
I’m a beginner but would the veil nebulae be visible if this is done?
@@tykingcrystal864 the veil nebula is an easy target, you can have great result with any camera but it s even better with an h alpha ( an a O3 filter )
I'm new to this, and it is absolutely beautiful! Thank you!
Bloody hell Alyn! This just blew my mind completely. I have watched Trevor’s and Peter’s videos but this was just amazing. Great work! 👏👏
Amazing as always, and Its your videos that have really got me hooked on Astro photography.
It’s all very new to me at the moment, but I’ve genuinely fallen in love with the night sky. So a huge thank you is owed, for inspiring me to try something different...👍
Fantastic Alyn - thanks for all your efforts you put into these astrovlogs the production value and results are awesome.
Lovely shots and superb wide angle! I just wish the sky was that clear back in Wales ☹️
Amazing video Alyn like always. Thinking of astro modifying my camera myself, before I think of getting one of these.
I am sure in your hands, that filter can do amazing things!
I have just moved over to cooled mono and H alpha is just amazing ! The amount of detail is just phenomenal!
As if I didn’t want an astro-modified camera enough as it was!!! Personally, I love the extra Ha... I’m always so impressed (and slightly envious) when I see nightscapes including it with a cool foreground. Looking forward to some more of these images from you now!
Your last remark about how these pictures would look to people who don’t know anything about astrophotography was spot on. This summer I shot my first star trails images and when I shared it with family and friends most of them did not know what they were looking at. I had to explain to them what the pictures were about and how they were captured in order to understand what they were looking at.
Those photos turned out great especially like the Nightscape with the Orion Nebula. I would be really interested in seeing a similar photo but taken with just a full spectrum camera no filters.
Oh Alyn, it's beautiful - love the technique and the results! Bringing out the secret smiley face in the sky :) Now I kinda want a setup like this, my poor bank account .....
@Alyn Wallace Absolutely stunning shots gives me inspiration to get out more with my camera (when the Welsh weather allows) keep up the hard work 👍👍
RE: wide frame Ha view of the Orion complex...Cool! Incredible! Amazing! So much so, I'm planning to try it myself - uh, after I get an Ha filter.
Thanks Alyn. I find your images not only superbe but also very original. Great stuff. Get some rest. Greetings from Belgium. RUDY.
Definitely looking great. I would love little bit more of the star light, maybe starglow filter too.😃
Alyn, as the saying goes, beauty is in the eye of the beholder.... that being said, for me I like to stay as much as possible closer to what we "could" see, and a subtle integration of HA+RGB so the pink/redish doesn't take over the image... but then again, that is just me.
Hey Alyn, love to see how you improve - for aligning Ha and RGB have a look at Astro Pixel Prozessor! It also works great on Wideangles ...
This was the first video I've watched of yours and I was very impressed. I'm a visual observer with aspirations of starting astrophotography. In that regard your videos are excellent, you are calm, clear, and do a great job of articulating the excitement and anticipation of astrophotography! You also explain the technical aspects of each step of the process very well, even someone like myself who understands astronomy and has no personal astrophotography experience. I think this video was great and I enjoy seeing these objects under different filters, thank you!
My first thought at that last image was "Damn that's pretty, but it would frustrate me having people not knowing the techniques/astro side of things asking about the weird red lens flares or something". That being said, I love the shots and the work with the filter! Looking forward to more!
Loved your images and your explanation about the filter. Your photography is so inspiring! Take care
It adds more interest to the image and makes people search more about what they see!
Thanks for this one Alyn from another brit doing Astrophotography in Turkey. I'm near Izmir, in Cesme and I hear what you're saying about getting the equipment and paying the taxes on incoming stuff. Love your videos and your clear explanations, been quite helpful to me trying to progress after nearly eleven months in the hobby.
Beautiful shots of the horsehead
Alyn - refreshing to hear that someone with your skills still considers themselves on a learning curve - a lesson for us all. Great images and another superb video
Sadly Alyn have passed away for the ones that do not know. He is now the brightest star in the sky R.I.P mate.
This is incredible Alуn! I have written out an analog of such a filter on Aliexpress! This is amazing! Orion just looks cosmic! I will strive for similar results. My setup: celestron sl mount, tair-3 lens, panasonic g7 and canon 6d cameras
I love the pictures and think they are beautiful!
Beautiful images, as ever! Your knowledge of the stars and photography go together so well.
The images look beautiful! Excellent work as always!!
I really love the wide angle shot. It makes you think about how little we actually see from the universe that is surrounding us.
I love these images. I find it fascinating that there are so many different ways to enjoy the night sky. Naked eye, binoculars, camera, smart phone, and different filters. My telescope arrives soon, i'm hoping to enjoy some clear skies.
The images are awesome, Alyn! Your videos are super helpful and entertaining. Thanks for sharing.
AMAZING,ALyn!!! I have learned so much from you!!! Thank you....
Thanks! All clip-in filters, or any filter placed between the lens and sensor will shift the focus point inward. The lens will now focus sharpest on stars with it set well inside infinity, perhaps at 6 m or thereabouts. That changes the optical performance of the lens, usually for the worse. Lens aberrations are designed to be at a minimum with the lens at true infinity. But with the focus shift introduced by the filter the aberrations blow up, so corners look awful.
Some third party lens adapters can do the same thing - adapted lenses can perform poorly compared to when they are mounted natively, at least with some third party adapters.
In either case - filter or lens adapter - the severity of the aberrations varies with the lens and its design, but is usually worse the wider the lens and steeper the light cone.
Clip-ins work fine on telephotos and telescopes with narrower light cones. I saw this demonstrated well in a filter test Peter Zelinka did a couple of years ago. The problem isn’t the filter itself but where it is placed and how it changes lens performance.
Filters over the front of lenses make no difference to focal position and lens performance. But that’s not practical / affordable for narrowband filters.
Great Video as Always !! 🔭✨🌌
"Love to hear your thoughts... " Right... ...................super ultra-cool overlay over the cityscape!! :D Mega beautiful work and effort! :D
Bringing out detail that the eye cannot see is amazing
Your widefield is glorious Alyn! I understand your thoughts about what people think who don't know much about astronomy, but the photos are so amazing and so eye-opening that I think they are as inspiring as seeing SpaceX launch their rockets. The point is to make people curious and interested to find out more. In that respect your photos are both beautiful and inspiring. Keep it up man!
To your last question, No! To us who do just Milky Way Galactic Center shots and show to others and others think that it is all PS art, and after explaining you get OH! AWH!....Doing the extra detail work to the camera and using the filter then the blending makes it even more Spectacular. Always in awe of clarkvision.com who did it with film for NASA and where I learned of the colors of sky gases after seeing them with AWB on my A7s. I am impressed with the use of just the 100-400 at 300mm to capture and better yet the 20mm 1.8 and 24mm f/1.4. A new image with filters!!!!
They are cool AND amazing! Well done Alyn. I have an H-alpha 12nm but haven't used it yet. It is supposed to clear tonight, so your video and prompted me to give it a shot. Thanks.
Hi Alan, I find your images simply super cool and very original. Thans à lott , wish I was already at your stage. Thanks and greetings from Belgium. Rudy.
I have a full spectrum X-E1 which I use for infrared photography. I'd love to give this a try, but I think I need a budget hydrogen alpha filter that's half decent because that's quite expensive.
Beautiful Alyn, I am building a rig of my own in the form of a 61mm or 80 mm APO and cant wait to attempt these as well with a Camera! I have a 8 inch SCT for planetary but this is a whole new ball game! Very impressed with the HA Filter with the moon, makes life alot better! Thanks!
Very good photos. I find the wide field one, with those red clouds of nebulosity, pretty amazing. They are not strange to my eyes. This is how we would see space if our eyes were more sensitive. Well done!
Well, since you ask.😊 I'm not new to astrophotography and I really enjoy it but I am someone who also appreciates realism. You don't see that when you look at it with your eyes so part of me is thinking it shouldn't be (so much) that way in a photo, even though I appreciate what goes in to the making of the photo. It's the same thing with shots of the milky way. You can see way over processed photos of the milky way online, many people saying what a great shot to those over cooked images. I prefer more realism. It's just me but then I'm also the guy who prefers star trails to be star trails, not comet trails. Computers allow us to do things that just don't occur in nature.🙂 You produce great videos. I share your passion.
Yeah I've seen a few of these 'deepscapes' popping up online and whilst I think they are quite technically impressive I often find the colours unpleasant in combination with a black sky and blue stars. It's all personal taste of course, but I sometimes struggle with my own images with awkward colour palettes like that.
Really great video though Alyn, fascinating to see this side of photography from someone who really knows what they are on about.
The final picture was stunning.
I really like the wide angle shots better than the too-often-seen telephoto images. Nice work.
You must work so much harder than me. I have Bortles 3 to 4 and a 10 acre hay meadow on flat ground with no livestock in the way.
Thanks for the information about and the demonstration of the filter.
Utterly beautiful and astonishing, particularly when used with Landscape. Well done! Superb work.
Came out amazing. Want to give this a shot before Orion completely disappears for a while. Great work!
The beauty of the sky and the objects in it are always a pleasure to watch...
⭐⭐⭐ 👍❤
Night scape images are always cool to see, and are much more accessible for the average Joe to replicate. I have seen a couple of these recently, and I love them. I think they will start to be done even more because they add perspective to the size of the things astrophotoraphers shoot. For example when you tell someone the Andromida galaxy is 6 times the size of the full moon people are like yeah ok and their eyes glaze over. Show them a picture comparing the 2 and watch their jaw hit the floor.
Definitely need, but I do feel like it is a bit misleading. I think there is a balance on the 'pop' that needs to happen if you are doing these for people to purchase. It's definitely a mix of science and art.
Nice work Alyn. Bought the CLS clip in filter for my D850 but have only tested once so far from the back garden.
I think you can get the same result using an L-enhance filter if you discard the G/B channels. The L-enhance is 12nm HA (more like 10nm), but you can get a RBG image out of it that's not too far off from natural color if it's processed right. I've messed around with mine a little, but have never really used it strictly as an HA filter to add data to an existing image. The Horsehead nebula picture I took with the L-enhance filter in Bortle 6 looks very similar to yours after adding HA data to the RGB. I think the main difference is mostly the star color, but its not too different after using star extraction and then processing the stars and nebula separately.
As long as the image is true to science, or as close to it, then it's true, no matter how weird it looks. Too many photographers add too many lies to their work with post processing, whether it's astro, landscaping, or whatever, until all you end up with is a Fantasy picture that doesn't and can't exist.
Great content as always.
Regarding the widefield images, strictly from a viewer's point of view - I see a potential problem in the color balance between foreground and sky.
The sky itself looks fine, the sea below looks decent as well. The green grass/trees/whatever though - not so much.
Folks who are into astrophotography know that the source of light in your image is not the Orion constellation and understand the difference in color balance in the final blend.
Folks who don't understand what sits behind the presented image however, I think they would find it weird that the source of light in the image is red, while the foreground is more on the green-ish/yellow-ish spectrum.
Looking forward for your Milky way images with added Ha channel! :)
They're extremely cool images. Nuff said!!! I saw a little clip of my home town Port Talbot from Mynydd Dinas towards the start of the video! Cool
Brilliant video Alyn! Full Moon is always a challenge (unless you are looking at the Moon) and you did a great job! Barnard's Loop is a big WOW!!. That's one expensive mirror, er, filter....
the last image is awesome
Incredible images Alyn, thank you 🙏. Personally I hope to produce this type of result eventually so please don't stop with these videos. I can see your enthusiasm to make the most of this filter and foresee some regular HaRGB content in your rotation 😉 👌👍. Cheers from AU 🍻
These look really incredible! Love the details, Alyn!
Great job, can’t wait to see your tutorial on blending rgb and hargb.
Great Video. I was thinking about that filter but didn’t realized until now, that I need to postP that in two steps.
In answer to your final question: Anything we shoot at night is going to be an exaggeration of what the naked eye can see. Thus, I at least, approach these shots with a sense of wonder at what is out there that the technology can reveal. The same applies to telescope images and even macro photography.
12:16 sequator reduce distor effects can fix this just sack normal data with ha it will fix it
Amazing got a 200pds on an Eq5 with a cannon 260d.but filter is nearly 200 quid in England. Nice video.
This one is a really good one. Thanks man!
Thanks for this vlog Alyn - really useful and the images were just mind blowing!
In my opinion, these images aren't misleading at all. They simply reveal the amazing size of the hydrogen clouds in our night sky. This is especially cool to see in the Orion constellation, because the three stars in Orion's belt give you a reference point so you can really appreciate the size of these Ha-emission regions.
That vlogging camera on the stars tho!!🤩
RIP Alyn
Alpha filter on Alpha camera 🔥
you can use a plug-in called star net to remove the stars from your hydrogen alpha images and it will make blending your photos much easier, better on star color too as Ha degrades the star color a bit. still great image
It's so fascinating and to be honest disappointing how much more actually is in the night sky, but our eyes just can't see it. How much more marvelous would the sky look like....
WoW 🤩... as always! You’re good, wry good. Awesome pictures
Really cool images, they add to the wonders of space
I can see this evolving further by using a filter wheel, and finally using a cooled astro monochrome camera soon!
Very nici video! I recently bought a hydrogen filter and it works pretty good. Keep up the good work!
Have you tried just the Ha filter with a non modified camera to see the results? You tried use any other filters and combine all the images with colors
It's a beautiful sight!! Love it, thanks for sharing.
That’s cool. When you say RGB is that 3 individual color filers? Then what kind of software are you using to overlay the pictures? I have a P1000, but was considering doing Astro Photography & full spec converting. I have the h-alpha and just turns everything magenta/red. I wanted to see solar flares live. It’s surprising way more complex than I thought to do this. Anyways. Your video was really great man and those shots are on another level. Looks completely professional & polished. Looking forward to seeing more of your work/hobby.
He is dead man
Stunning images and a great video again Alyn. Thank you.
Trevor Jones is a pro now in Astrophotography. Astro-backyard indeed has quality stuff
Super cool , great result to see the size of objects
