Altair 6nm Dual Band Filter Review: A Light Pollution Killer 

yes! I did have same reaction when I try a dual band at 7nm, being in a Bortle 7 sky zone I apreciate this filters, I use SV220 from Svbony on a pentax Camera and on a IMX585 color astrocamera from Player One, model Uranus C PRO with a rokinon 135 f/2.0 . . . my jaw drop to the floor, when I saw the Crecent Nebula for for first time in my life, colors and contrast between the red and the blue green was too mucho for this city boy. It is a game changer for poluted skies, and for the whole comunity of astronuts doing astrophoto.

5:27 Is that Grolsch beer on your right? Greetings from the Netherlands. Great review of the filter 😁

"I gotta stare at this for a while", followed by a title card "One month later". OK, I know who I'll never challenge to a staring contest...

These kinds of filters are a game changer. I just got my first actual rig with an ASI294MC and a Svbony dual band filter and it blows me away with how much it brings out all that hydrogen

I love your off the wall style of videos. Really appeals to my wacky sense of humour. Keep up the good work 😂😎👍

Absolutely wonderful results!!

Wow, great pictures Walt! well done

Crazy stuff. Absolutely outstanding!

Great video and thank you for the info on the filter.

Outstanding! I like your style, mister.

What makes it more crazy is the non-existed bloated stars and the texture of the nebulae it can come out with. Great recommendation, Walt!! 🤩🤩

Thank you for doing this video. Seriously it’s so helpful and informative. I’ve got a quad band from these guys and that’s very good but this looks like a game changer.

A cooled, dedicated astronomy camera is such a gamechanger it is hard to describe. I used a modified T5i too for about two years and I was really happy with the results it produced. I bought a Player One Poseidon C-Pro a few months back and the difference in quality just can't be compared.

Your reaction-PRICELESS!! Thank you soooo much for this video. As always, YOU ROCK!!

Those were awesome images!

Great video and images! Welcome to the world of cooled dedicated Astro cams and dual narrowband filters. Increases the fun factor!

Some really awesome shots at the end...and nice video! I have the SVBONY SV220 like a lot of people commenting, but I've only used it once. I got a nice HOO California Nebula out of it though!

Hey Walt! Wow great site. Nice to meet you at the Wharf last night (I was the guy at the bar)

Wow those pictures really blew my mind at the end, that filter is something else! Also is that a real-to-reel in the background towards the end?

Great video! I'll put this on my (long) gear purchase list 😂😂

That picture of Thor's Helmet, NGC 2359, (14:12) is absolutely amazing! Very nicely done.

Love the Clarksdale shirt! Reminds me of the old Greenville slogan we made fun of 'Greenville-Catch the Spirit!" Really enjoyed your excitement with the cooled camera!

Very nice. I think you sold me on this... FATALITY!

Hi Walt!! Happy New Year. Great video as usual. Quick question. I have a Canon drop-in filter adapter. Does this 6nm filter for Ha and O3 from Altair fit in that or I need a special filter adapter? Other than Altair, does any other company make the Ha-O3 Bandpass filters that can use with the Canon’s drop in filter adapter? Thanks.

Great video Walt ! Very informative. I shoot from a Bortle 8 zone with a full spectrum DSLR viewing through a 70mm doublet refractor on a SWSA GTi mount. My question for you is: can I use this filter with no guiding and shorter exposures ? I typically expose for

Good review Walt. I live in the UK and it is the VAT which runs at 20% that makes everything expensive. I use a lot of Altair Astro products, I have in fact just bought one of their 115mm f7 refractors though I think this is the same scope as the one sold in the US under the Astro Tech brand. Their high end filters look really good but are also very expensive. I use their 6nm narrow band filters and are very happy with them.

Hugs, great video, so right, sometimes you’ve just got to look at what you’ve shot, that thrill is what it’s about

I just thought id let you know you've taught me to hate clouds and light pollution. Ty ;)

"I gotta stare at this for a little while" ONE MONTH LATER 🤣

Besides picking up some good information (I'm very much an amateur) here, I got a real kick out of seeing all of your Grolsch bottles. LOL! That's my go-to beer and I wind up keeping the bottles for all kinds of things.

I have the RedCat 51... Do you know if this filter would work with the Starizona RedCat DSLR Filter Slider Adapter Kit so that I could use this filter?

Great review! Ive seen a couple of peeps sayin these filters help even in very dark skies, i would agree to some extent as they will also block reflection bits and faint dust and IFN! Dont be scared to go for more minutes exposure in the city, although that band seems very odd, maybe sensor related? Check it out with your new 294mc pro. You should get a filter wheel and an S2 O3 filter now to create SHO palette and help us with the workflow. Thanks Walt! PS: what was the last targets name? Very cool one.

Really fun and great video ❤

WOW !

Where do you posts/sell your photos ?

Great images, Walt. Do you use a filter drawer on your "optical train?" Also, did you polar align without the filter?

Could i attach this to a camera and use a lens with the camera?

what would be (in your opinion) the best solution for shooting Galaxy in Bortle 4-5 regions. I noticed how dark the sky looked at night a year ago when I put a L-Extreme in my light train. It was amazing. Glad to see that they have a HA-OIII and SII-OIII combo available.

Even at this price, filters are costly. Seems every month a new one is reviewed. I'm in bortle 8-9, so no doubt this would benefit me. Im using the optolong L-enhance now. Comments about the SV220 peaked my interest. Its $130 right now. But the Altair has documentation. Is the bandpass acuracy of the SV220 as good (repeatable) with all pieces?

FIGHT!

You should try setting up in downtown Memphis next! 😂

antlia alp-t is 250 usd + tax, 5nm and is for me working really great. But yes, you dont get the measurements.... ;)

Actually, I know of at least one company that did it, but let us not advertise them, as I quite like Altair Astro -- let's advertise Altair Astro :D.

Walt, mate what are you eating?! You need to add veggies too!

Why do all these astro filter companies cater just to Canon users is what I'd like to know.

i see terrible halos with this filter

I love your video style Great review. Just a note I use an optolong L-Ultimate at 3nm and have no issue plate solving or polar aligning or autofocusing with my scopes and asiair. Just increase the exposure by a few seconds
