Great video, Will. I had a lot of fun at this year's Okie-Tex looking through that night vision eyepiece on Elvira. The views were fantastic! As nice as your video is, nothing compares to actually seeing an object like the Helix Nebula through the NV eyepiece.
Agreed. No picture could ever capture the detail your eye can see. I'm busy editing the main recap video now and I caught some fun stuff!
Pretty cool stuff. And what a dob.
This is amazing footage
Thanks! Yeah seeing some of these galaxies this way is life changing.
That. Is an incredible setup. Quite literally out of this world. I cannot understand how anyone can ever believe a refractor or sct can compete with a tube ! Man. What a system.
It’s a lot of fun! I think it’s hard to say it’s better than regular observing but it definitely does give you another perspective. 🤘😁
Image quality. There is no noise whatsoever when observing through a scope. I, and many others, prefer a darker noiseless image that shows detail instead of basically pure noise with barely any detail.
Knowledgeable video 💖💖💖 thank you for sharing 🙏😀🎁🎁🎁🎁🎉🎉🎉🎉🎉
Awesome.. I love Those Live Views Really.. Awesome🔭👍
Very high-spec’d tube on that PVS-14! Damn I’m jealous. That’s beyond aviation grade. I wonder what the FOM and HALO are.
Hey!! I don’t know the exact specs of his but I know they’re probably over 2500 FOM.
ridiculous spec on that tube!
@@DeepSkyDude SNR of 41 and 72 line pair yields a 2952 FOM. EBI of 0.5, this is truly an exceptional tube.
New subscriber bro... This video help me a lot!
Awesome!! Welcome to the page!
Really interesting about using a Night Vision Monocular at the Eye Piece. Is there an entry level night Vision Camera available worth looking at , as the Cameras on the link are way out of my budget ?
thanks
Nebula and galaxy are so beautiful. I also really want to have the equipment needed to film like you
Toàn Nguyễn agreed. I actually don’t own any of this equipment yet. Still doing research and figuring out how I want to go about this.
You should have a big dobsonian like 16 inch or 18 to see like this but real colour without night vision it like silver cloud spiral galaxy
Mis KITKAT BOOM Boom I have a telescope 5 inch .😁
Thanks for sharing this great video. I find NV fascinating for astronomy. In your video I can see random spots twinkling, is that something that happens also when you watch live with NV? If so, then how distracting do you find it and can it be somehow remedied?
Yeah that’s called scintillation. It’s a by product of night vision devices. While you can spend more money to lessen the effect, it will pretty much be in there no matter what night vision device you’re using. I don’t find it distracting at all while viewing. Your brain can be trained to ignore it pretty easily.
In my next life I'm gonna be a gear head. This is just awesome
Very meticulous and high class!
Aether52 thanks! I’ll definitely be doing more videos on this sort of thing.
Amazing
Wow, what a sweet telescope. Very jealous!
I figure you could use a PVS-14 to effectively increase the aperture of a telescope as well, at the expense of a noisy image. I wonder what ways there are to improve this method?
live stacking
Hi, what is the name of that wrench? Great video, thx for posting.
I think it's a spanner wrench.
Very nice
That's a beautiful setup you got there. I'm sure that was a few bucks.
Wow that's amazing wtf
Since ZWO ASI462mc camera is sensitive to Near infrared. Will it help to photograph in IR as you've shown???
Nah this is a completely different thing. It isn’t IR, it’s visible light that has been amplified.
Where theres a will theres a way.
May I ask where have you got the rubber eyepiece guard for the PVS-14?
That’s a great question. I’ll ask him when I talk to him next.
Wow I didnt know that amateur astronomy can go this far. It is amazing what eqipment we are able to get these days. Of course it's constly, but it's doable if you put your mind to it.
41 SNR?! Jesus christ
Hahaha Right?! I NEED to know who he bought that from.
Hello! What H-Alpha filter are you using? 3.5; 7; 12 nm? And which one is better?
I think it was the 7nm.
@@DeepSkyDude Thank you
Interesting, I just picked up the same TV PVS device and in my backyard in the city with enough ambient light to read a book by, I don’t have any noise like in the video.
Right now I’m just using a Plossl 32 with and without a filter and set the PVS gain to the lowest to provide the most contrasty image and wow.
Makes my TV85 perform better than my 10” Dob I parted with last year.
Yeah if you turn the gain up you’ll get more scintillation. In order to record video with a phone’s camera you really need the gain most of the way up. For visual use you can keep the gain very low and still get a great result.
how cool is this
Agreed!!
Is it possible to take these same images using long exposures, or is the earth rotating too quickly?
Good question. These videos seem to be stabilized fairly good, Id assume that would be possible. But I'm not sure how long exposures work with NVG's, might not make a big difference but I don't know it very well could.
This will also work with a PVS-7 binocular.
that telescope is INSANE. wow
Wonder what that video looks like stacked
Not too sure?? I never really thought about stacking the videos of deep sky stuff before.
I’ve seen sooo many videos that don’t have anywhere near the static in the video quality.
Can you link the items used?
idk about the rest but here's a link to the same night vision device he had (PVS-14) you can configure it the way you want tube wise to get the same setup (He was using L3 WP unfilmed)
steeleindustries.com/product/an-pvs-14/
41 snr and 0.6 EBI? dang man. That is a SUPER night vision tube right there. a normal PVS-14 with a l3 tube costs $4,500... that thing people would pay $6,500 for
Yeah Ed’s is a super high quality one. Mine isn’t that good but it’s close.
I have a 0.0 Ebi tube. Would that be very beneficial to night vision astronomy?
Interesting
What does a seup like that cost? 50k?
Good night version in malaysia cost 1 k even up 3k
Dude, here in europe 2600 FOM high end night vision would cost about 10000eur
high quality NV here can cost up to 5 grand for a monocular if you want the best
Dude, I have to ask. Where did he get his night vision device?! I've been looking for specs of that caliber
I'd check steele industries, NGI, or TNVC
here's a link to steele I had them tabbed steeleindustries.com/product/an-pvs-14/
Can I see horsehead nebula with 10 inch telescope + Gen 1 night vision? Sadly, I don't have enough money to buy Gen 2 night vision.
Or very dark something...
You should be able to do it with a hydrogen alpha or hydrogen beta filter. You’ll need one with a band pass of 7nm.
So I really want this setup.. can somebody please tell me the make and model of everything in the video? I want exactly what this guy has and willing to spend the money
The night vision device itself is a PVS-14. Those can be ordered from many retailers. The attachment stuff is all Tele-Vue. They also sell PVS-14’s as well. I’d give them a call and see what they have first.
@@DeepSkyDude Thank you. Quick question, if I could only get the PVS-14 would that allow me to see more star's?
@@petergriffin383 it depends on the ambient light pollution. In the city the NVG’s amplify the light pollution along with the stars at 1x so sometimes it doesn’t help. In non light polluted areas, it absolutely increases the stars you can see. It’s wild.
The amount of stuff you see moving around under NVGs should remove any doubt in your mind that we are not the only intelligent beings in the universe!
Yeah those satellites sure are smart these days! 😆
@@DeepSkyDude can you upload some of the objects emitting an air signature but not moving in a traditional orbital pattern?
@@tfunai8164 I haven’t captured anything out of the ordinary in all my years of doing this nearly full time. Sorry. 🤷🏼♂️
@@DeepSkyDude Well with a telescope aimed at stars, with a tiny FOV you ain t gonna see much zooming past will you! lol.
Ive been sky watching for 10 years, and once in a blue moon, I will catch round objects in fighter formations travelling much faster than satellites. Altitude is hard to gauge, but its not at commercial airliner heights that's for sure.
I once witnessed a satellite looking object, do a right angle 90 deg turn without losing its forward velocity.
These happenings are super rare, which proves to my mind it is rare - and very real.
What is the third picture you show? What galaxy?
That’s NGC 253, the Sculptor Galaxy. Definitely one of my all time favs!!
That's a super nice telescope. Nice video.
I live in Pennsylvania. At 3:00 am directly above my house I see something like that with just a PVS 14 gen 3 white phosphorus very thin filmed. ( all PVS 14s are filmed. The real thin filmed ones they advertise filmless but they have a very thin film) PVS 14. Its directly above my house . I have to lay on my deck to look at it or my neck starts hurting.
What can what I am seeing be?
@@briankudalis9572 more than likely you’re seeing Andromeda. M31 is another name it’s known by.
Thankyou that's what it looks like.
@@briankudalis9572 so I did some digging and actually not all PVS14 are filmed. Thin filmed and unfilmed are two different things. Thin filmed doesn’t work well for astronomy at all.
GREAT But a show-off. I'm a beginner looking to stargaze with infrared cam or something that I can put on my Celesteon 127 Powerseeker EQ. Yes said I'm a beginner.
forgot to tell us what size telescope he is using.
Nah we didn’t forget. This video was about the night vision. 🤘
I'm jealous 😔
Instead of showing the night vision in action the guy is showing off his scope lol.
This video wasn't about seeing the night vision in action. This video was made to show the method. It's right there in the title...
Woulda been nice to show more pics. And where's the dang phone?
The pics are usually posted on my instagram and Facebook accounts. Head over there to see those. The phone was being used to record this video. lol
You lost me dude. I’m looking for something I can do, that’s a big telescope. I thought you said phone! :(
I did. That’s how you film it once you amplify the light. 😆😆
19 layer Carbon, built in filter wheel? did he build this Newtonian ?!
Yep! Designed and built from scratch.
@@DeepSkyDude gotta love the passion! did you ever post a video of the same night, viewing through the NV?
daslolo oh yes. All the nights are together in the Okie Tex Star Party 2019 video. 😎
@@DeepSkyDude love it, heading right there
shocking. why would anyone with all that quality gear not connect a good ASI2600 and take quality images. Why a night scope and cell phone? No logic or reason to this? The entire video I keep thinking wtf. This is like formula 1 racing but putting a VW beetle power plant in the car.
LOL. Umm. Have you ever tried to image with an astrocam on an ALT/AZ mount? You need field de-rotators, auto-guiding and then you have to process the image the next day. You don’t have to do any of that with this set up. This set up is meant mainly for visual use with the iPhone as a secondary accessory. Lol that thought never crossed your mind, did it? 😆😆😆 There’s plenty of “logic and reason” for this. It’s fun and it’s a different perspective when you see it visually. And your analogy of the VW is laughable. Clearly you’re someone who doesn’t get it. 🤷🏼♂️
For visual use man.
