@1:47 Scientists outsmarting politicians to build new toys warms the cockles of my heart :')

This 2.54 m Isaac Newton Telescope (paraboloidal M1 is made of ZeroDur) is mostly used at the f/3.3 primary focus, where there's normally a 0.50 m secondary hyperboloidal mirror... The Cassegrain focus is f/15, a Coudé focus was never implemented. Thanks for posting DeepSkyVideos!

Our whole astronomy club is now following you on youtube! Please don't stop! - Astronomy club of east Lithuania.

Rafa's jumper is the best thing in the video, LOL

A lot of people don't realize that you can get pixel to pixel variations. But in addition to that you can also get subpixel gain variations. I once helped with some research on subpixel variations in gain for dithering during some summer research back when I was still in school. Even thought it was a backlit ccd, as in all the electrical bits were hidden and only the back is showing, you could almost determine the structure by looking at the subpixel gain for different pixels across the ccd. It was for a satellite at the time that got canceled eventually. Another thing that a lot of people don't know is that there are also hidden pixels around the outside not exposed to light that you can use to calibrate the ADC for normal noise generated thermally during a photo. Also some CCDs may have different ADCs and read the image split down the middle or even quartered, and as the CCD ADCs are physically separate they have slightly different gains from manufacturing so somehow they must be normalized between them as well.

@ashwinnarayanVlog "normal" people go up there a lot during the day... coachlaods of tourists... Actually going into the facilities is not so easy, unless they are specially arranged open days I think? But I'd really recommend it regardless... You can do some great walks and the observatory is right next to a national park which is gorgeous.

Thanks Brady for another absolutely awesome video. It's really interesting to learn about the behind the scenes activities that go on.

@IcEye89 it is indeed - they are all like that! You'll see inside more telescopes soon!

@TheDingiso yes, that was on BackstageScience - that was a pretty cool device. It is called KMOS.

I'm really loving this channel! Keep it up!

Each summer I'm going to the turkish Aegean coast. Found a safe place to store my 8" SCT and the rest of the gear. Excellent sky quality no glow and cheap fares. I would strongly recommend for amateur astronomy.

I can only imagine the mood with all that silence and almost ritual preparation for the observations through the night. It must be extremely satisfying. Thank you for these great videos!

THANKS for the vids from all your channels

@NictraSavios I wonder if I block you as a user from DeepSkyVideos it will remove your dislike? Should I try it? Or should I resist? ;) Thanks for watching anyway.. Thumbs up our next video and all will be forgiven!

thanks so much for sharing this. I enjoyed watching very much! so cool. Also, Rafa's jumper was pretty cool lol

This channel is the best thing to happen to youtube! I'm learning so much with these videos. Makes me want to go out and buy a telescope to try to find stuff on my own.

Excellent journalism Brady!

Looks very peaceful up there. Love the vids keep up the great work!

@MrSuperZangief it's good... I didn't sleep much for the whole week at La Palma - but it was worth it and we'll have loads of great films to share! :)

Wonderful video about the daily life of observation. Hope you make more of these!

Thank You so much, Brady! It reminds me a bit of another video your made about the telescope that can monitor multiple objects at a time

@Xayionify you're welcome... always nice to hear from people who know about all the other channels! :)

I do indeed love all of these videos. Got to say I am jealous I didn't begin these first! If you need to outsource editting or such, let me know.

Thank you so much for making these videos!

Brady's such a flirt I love it

I do also take skyflats with my 8 inc telescope and your discription was perfect.

Great presentation. Thank you!

Thanks Brady.

It's great to see the hand-on details of an observing session - even if it is just a tiny 100 inch scope.

Awesome video = ) It must be cool to work above the clouds!

Great content, endeed, and also with a funny and unique aussei accent.

Very interesting video and I liked that it included the nightly calibation details on the CCD assembly because I never heard about that before, even on the Science Channel astronomy specials and did not know it was necessary. I wonder if some of that nightly calibation of uniform (dawn/dusk) skys could be accomplished by computer automation. Perhaps you can ask these fellows. Thanks for posting.

@DeepSkyVideos I once told you that you sould come to Chile to visit ALMA and the VTL.

Nice, seems so incredible. You seem to have a wonderful job.

I... Love...These... Videos. Thankyou...Thankyou...Thankyou....THANKYOU!

Great video, thanks for sharing. I had no idea the bigger observatories had to take flat frames. I was under the impression that was just something part of the amateur world imaging the sky with DSLRs!! :)

Awesome video

@patcs87 that would certainly be interesting!

awesome, very interesting stuff!

@unluckylion it makes life easier I think... one less thing to worry about.

@DeepSkyVideos Thank you so much for sharing this. Absolutely fascinating stuff, I've always wondered what happens during their observing sessions. I have more questions though - I wonder if stars on his master flat will induce noise/star prints and also why/if they use a diffuser when taking sky flats. Thanks for posting this, it's incredibly interesting stuff!

@hla27b thank you

Lovely report mate

amazing, please post more videos. People always wonder how real astronomy is done.

@P55CxE9 I'm sure you'll see a bit of everything over the next 12 months, including the smaller telescopes! But you'll also see plenty more of the BIG ones too!

Very interesting. I wonder what happened to the original 98 inch mirror.

@DimsimMaster Yes, it blocks some light. But there's still plenty of light that does get through. It doesn't cause a black spot in the middle of the image.

Rafael did all this with one hand in his pocket. Impressive.

@noswonky plenty more to come

the skyflats image was quite interesting. it looks like the center of the sensor has been "burned-in" from always having the "bright" star or nebula focused there. similar to what happens with the CRT on a radar scope.

This is cool!

Man , this is great.

'Any astronomers watching, I apologies for that description'

Awesome!!! Dream job right there! :p

@PinkyPurply me too! tell your mates! ;)

Does anyone know if any of these observatories have an eyepiece attached to the telescope to view the sky directly. I know it's impractical, but it seems like it would be much cooler than looking at an old pc monitor.

It did have originally when it was at Herstmonceux.

very nice

when is the next Messier video? I loved this one, just curious :)

3:36 "We cool these detector to liquid nitrogen temperatures". Incorrect. Dark current on most CCDs falls to almost zero at about -100C and further improvement with even lower temps is very small (while technical difficulties and cost increase), so they are usually cooled to -100C (sometimes to -120C lowest). Not to −195C (liquid nitrogen boiling point). Yes, liquid nitrogen is often used, but CCD temperature is not brought down all the way to its boiling point.

I love how Rafa pretty much is not paying attention to what Brady says, he's so concentrated.

@Sh33un They take a bunch of these images, not just one. Also you can change the direction the telescope is pointing inbetween the images. Everything that stays in exactly the same position, down to the pixel, is what you are looking for. All else gets erased when doing the composite image.

@jancheck that's okay... I enjoy it, in case you didn't notice! :)

If you ever want to know more about how they moved the INT to La Palma, speak to Neil Parker from "Green Witch", who was part of the team that did it.

Very cool, what software are they running for the telescope on the Sun Microsystems computers?

Awesome :DDD

Nice to work in this field.

I would recommend them an equatorial mount for astrophotography. Perhaps maybe a Sky-Walker EQ-6R Pro. 😉

Because they are geared for slow precise movement. Fast movement would put unnecessary strain on the system and reduce the precision of the pointing

im learning more on youtube now than i ever did at school..i dont know if thats good or bad...

I wanna live there

Have a good Australia day Brady.

@NictraSavios Voted down your post, loved it but i couldn't resist :)

Noob question. Wouldn't the sensor be blocking the light coming in since its right smack in the middle of the mirror?

How do they move the teleskope, how do they move the dome, what operating system do they use on their computers? Proprietary?

The telescope used to have a seat with which the astronomer could sit in at the bottom to look through a viewer when it was at Herstmonceux, is this still on there or has it been removed?

cool man

OMG this was amazing! Our little telescope in Givataaim Observatory is making more noise than this.

Rafa has my dream job

It's really weird to see such a huge structure move without any sound

Is Raf'a the only guy at the observatory?

And now I go out on my deck and look through my 102mm refractor!!!!

Is it too much to ask for longer episodes? haha

subtitle please. Thanks

How can they take pictures only with the main mirror

this "small" 100 inch makes my 8 inch telescope sad :( i want a 100M telescope!!!!!!!!!

OWL telescope! 🙂

So does it use a Newtonian reflecting telescope?

@NictraSavios I always forget to like videos--but this reminded me to! So I cancel out his suck!

My First view of this video ,what the heck a 2.4 metre mirror is not big enough for critical observing just general observing 😳🔭

Sorry for this noob question, but why does the observatories have to open up so slowly? Any specific reason?

mightyboy1994 I'm assuming it's to reduce the wear and tear on the components. Could be very wrong, though.

@culwin Sound like something Duck Rodgers in the 24 & half century would do to Marvin the Martian.

can't believe that telescope this large is used to film wide field.

Feel like they should have renamed it the telescope of Theseus

Where is this place? Can we actually visit it?

@ronnystoehr only comments like yrs remind me there are ads on yt. adblock plus my friend. i would have tossed in yt a long time ago if had to watch ads

What about the timelapse ?

Rafa flew down the stairs with one hand in his pocket, he'll do himself a mischief if he's not careful

small 2.5 meter telescope :) my 127mm mak-cas is an atom size.

So a sky test is like a 'white' test that you used to do with old cameras?

Wow. I really wish I could visit that place one day. Can normal people go up there to visit the telescope or is it for astronomers only?
