ADC (Atmospheric Dispersion Corrector) Tutorial

A long-overdo tutorial on how I use the ZWO Atmospheric Dispersion Corrector. ZWO Atmospheric Dispersion Corrector is used to reduce the effect of atmospheric dispersion on lunar and planetary images. Light from any star or planet that enters our atmosphere at an angle will suffer refraction effects which bend to light to a slightly steeper angle. This refraction effect makes the object appear higher in the sky than if the atmosphere wasn’t there. The degree of refraction depends to a small degree on various things like temperature, humidity, observers and height above sea level, but does increases strongly with decreasing altitude of the object.
Join me as I show the ADC in the imaging train and use it in real time. Then I process some Saturn and Jupiter data and show the before and after effects in Registax.
Again, I wanted to apologize for the long absence, but after coming back to work my channel just had to take a backseat for a little bit. I am truly grateful to everyone who stuck around and all the new followers as well. I have some great stuff planned and I hope y'all enjoy!
Clear Skies!

Merci pour tes explications sur l'ADC je ne savais pas pour le Newton 😅 (joli reflex pour la chute de caméra 😅😁👍)

I can’t even remember why it fell! 🤣 It was just sitting there and it wasn’t windy.

My Planetary Photos Don't Really have a Lot of Fringing in them, Because it's Pretty high in the sky. Though sometimes I get The Issue, I'm not sure if an ADC is Worth it, Because it adds A Lot of Weight onto my Image Train on my teeny 5 inch Reflector. The RGB align in Registax Doesn't work completely, It still shows some of it. Great Video man, good luck with captures of Saturn and Jupiter in Opposition! Not too long to go now 🙌

Hi Matt, this is the best video I've come across about the ZWO Atmospheric Dispersion Corrector - as well as about ADCs in general. It's much appreciated!

Nice tutorial. The Jupiter images look fantastic. Was surprised how stable Jupiter looked in Firecapture in that high humidity.

@Chorge1972 Месяц назад

Superb!! Thx

@rajsastrophotography 2 года назад

Holy cow I need that.. most of my planet images has that issue, I use to remove it on photoshop but it’s not that great.. I never knew you can fix that in Registax either😂 Thanks a lot man.. also when you get a chance could please share how you stack jupiters moon? Mine always looks soooooo bright 😕

@InsertAstroNameHere 2 года назад

Hey Raj! Registax is really powerful at doing very specific things. Obviously the better capturing and stacking you can do, the better. And yes, I can definitely do a short video on Jupiter’s moons. Thank you for the suggestion. Anything else?

@Guido_XL 2 года назад

I also get color dispersion with my Jupiter and Saturn, shot through my Sky-Watcher 190/1000 Mak-Newt. Registax is not getting it all out, although it does a pretty good job. So, I'm considering an ADC as well.

Great video. Our family is looking to jump into planetary. We have a CPC 1100. Just need to take off the diagonal and put back whatever part we need to image from the back (bought it used so not too sure where that part went).

Nice showing the ADC and RGB align. I may need to pick up an ADC. CS!

I did my best ☺️

@ChristianPsencik 2 года назад

This is a huge help, thank you! I’m also impressed with your individual frames. You must have some great seeing these nights. I’ve got a 10” SCT And I’ve never seen anything close to that level of detail. Wow. Maybe I need go tweak my focus?

@InsertAstroNameHere 2 года назад

Or collimation. The seeing has definitely been on the excellent side, but unfortunately tonight is a bust 😢

@@InsertAstroNameHere do you use a Bahtinov mask for focusing on a Star then switch over to a planet or can you just eyeball it perfectly?

@yellowlynx 2 года назад

Good tutorial. Buy some of those "ice" napkins if you really need to image in the hot Summer. Your sweat will drown mosquitoes.

@InsertAstroNameHere 2 года назад

Sometimes that humidity just sneaks up on you. Lol

@georges.5612 Год назад

Hey Matt, after more than a decade, Registax finally has an update. The programmer named it WaveSharp. It is free and does the wavelets and aligning Registax does. Pretty neat. Check it out. While Registax is great, it is a dated piece of software.

@outputcoupler7819 8 месяцев назад

Seeing you sweating makes me glad I don't live in Alabama anymore. But then I remembered that time I bought a new camera and briefly got confused into thinking it was a cooled model because the sensor was reading -10C. Nope, just that cold out here! The camera loves it, the astronomer not so much.

@craiglowery4427 2 года назад

Great video Matt. I’ve missed your videos. BTW I grew up in South Texas but live in dry Colorado now but mountain turbulence gives me focusing issues. Can you do a polar alignment video? Thanks.

@angelo327able 7 месяцев назад

This was helpfull. I'm a Newbe and wondering how insertion of the ADC affects the back-focus setup. On the C6" the back focus is 5" or 127mm beond the Visual Back. Doen't the ADC move the camera beyond that perfect focal point?

@InsertAstroNameHere 6 месяцев назад

For planetary or Lunar imaging it shouldn’t matter. Assuming its a standard SCT and not the Edge HD version. Then I believe it matters due to the field flattener.

@deepthought1569 9 месяцев назад

Nice video bud, I've had my c11 out a few times up here in Ohio. I've never seen raw detail like that in my scope. I have the zwo 533 now and haven't had a chance to use. I'm hoping its my bortle 4-5 seeing.

How do you like that camera versus the ASI to 290 color. Is the chip bigger

@sebastianbroda9663 2 года назад

Hi Matt, I heard that your insta account was hacked. Are you making a new one or do you have a chance to get the old account back?

@InsertAstroNameHere 6 месяцев назад

I made a new one with the same user name. The old one is still up and after countless attempts to try and get it back, I gave up. The whole ordeal really made me despise Instagram so I took a break for awhile and went through a bunch of personal life changes at the same time. But I’m ready for the eclipse and plan on doing more RU-vid vids. I greatly appreciate all the support from the community ❤

@lucabilleri1359 2 года назад

A Quik question: why you use the barlow after ADC?

@DirkDirk1983 Год назад

Same question here. Cause the Barlow is a lot heavier than the ADC. Can not imagine it would make any difference though.

@fabioyt77 Год назад

Hi, i think cause has an asi 462mc with a 2.9 sensor and a 2x barlow, so it's probably already near to the sampling limit, if it also put the adc between the camera and the barlow will increase distance between barlow and camera sensor and would oversample too much

@rockdv75 Год назад

Hi Matt, watched your videos. Bought a ZWO ADC. Followed your tutorial here. When I got to the point where I RGB align in Registax . It actually pushes the colors WAY off. Does that mean I'm not using my ADC correctly? I feel like it's a touchy process lining up the red and blue in the image session.

@astrodysseus Год назад

Do you think the ADC is that useful if you anyhow RGB align in post process ?

@iphoneawesome123 10 месяцев назад

If you are doing mono rgb then it doesn't matter much. But one shot color rgb you will get a lot of blur if the image is not pre shifted. Rgb align in post process is great but you'll get a better result if it's pre aligned.

@fuffi3076 2 года назад

Can I connect the ASI Camera directly on the ADC? I‘m asking because on their website is, it is T2.

@Rafastro Год назад

Can I ask you about back focus? I noticed that you don’t have any spacers to achieve your 146? Is it exact? I’m gonna have a similar set up with a 14….. Thanks!
