Seeing those black printouts and knowing how expensive printer ink is makes me nostalgic for old-school negative star images. :-)

[@revcrussell]

That isn't ink, that is toner. Laser printers use toner and cheaper all things considered. I think it is like 14 cents per laser color sheet including the cost of the printer and paper.

[@saltpot]

Dr. Becky is on Deep Sky again! Woot!

[@garyhuntress6871]

Love the astro-trivia as much as the astronomy

[@RedBar3D]

This really makes me wanna get into astronomy. What a cool story.

[@Mrfailstandstil]

Math and physics will stop you

[@RedBar3D]

@@Mrfailstandstil Well, no. I'm already studying maths.

[@DrakePHOSE]

Yall gotta link Becky's youtube channel, which is excellent.

[@M4rtingale]

Go ahead then

[@DrBecky]

Thanks! 🥳

[@vaderdudenator1]

HOW DID I NOT KNOW THIS WAS I THING??

[@bazpearce9993]

Everything in the night sky is amazing. Including clusters Dr Becky.

[@fernandoschuindt1665]

I was observing M7 tonight from my 210mm f/6.62 dobsonian scope. It was beautiful, and it brought me here. Thanks for the video!

[@M4rtingale]

That was a fucking expertly hand drawn circle

[@clydecessna737]

We usually pronounce Ptolemy with a silent "P", BUT we tend to say Ptah (Egyptian deity) by pronouncing the "P". Only by looking at a contemporary greek or latin translation could we know for sure. It is understood that Claudius Ptolemy AD 100 - c. 170 who we associate with astronomy is NOT related to the also Greek Plolomeic dynasty that ruled Egypt until the death of Cleopatra VII in 30 BC.

[@SharpAssKnittingNeedles]

I always wondered about that but never got around to looking up whether he was related to the pharaonic dynasty. Thank you for the info!

[@Eban11235]

Always heard it pronounced the way you did it. Also he's long dead so it's not like he'll get offended.

[@YYFGGUKYGJSHBJSHBJLS]

How DARE you!

[@timewalker6654]

in greek, he is pronounced with P.

[@PyroElleh]

[@michaelcollins966]

Only 20 more to go until the list is complete! Keep it up Brady!

[@stephenbedford1395]

In July M7 will be directly overhead where I live in the evening (Brisbane, Australia), followed closely by M6 and M4. (M5 lies slightly more north in Serpens).

[@jja77a]

Hi Becks 🙋

[@DrBecky]

jja77a 👋

[@2012TheAndromeda]

Thanks for the detail! That's amazing stuff!

[@zapfanzapfan]

Cool that you are still doing DeepSkyVideos as well! M7 was quite close to the location of Pluto in the sky, ok 10-ish degrees, but still pretty much in the same direction anyway :-)

[@Luke-cv7bg]

"M7 is the lowest numbered Messier object we haven't covered..." What happened to M5? It's not in the playlist . Thanks for another intersting video.

[@denisroym2110]

Indeed! Where is M5?

[@diwitdharpatitripathi6782]

Dr Becky

[@rmann22]

Useful and interesting star clusters are two different things.

[@antoinettemalone2212]

The star marking the "tail" of Scorpius is called Shaula (λ Scorpii) "the Aculeus or Stinger".

[@Macieks300]

2:18 It's a bigger gamble to test your equipment responsible for maneuvering last. After all you can't take pictures of Pluto if you can't go to Pluto.

[@DrBecky]

Maciek300 😂 very true!

[@francoislacombe9071]

Well, it's not like they can get it back in the shop to make repairs if things don't work. 🤔

[@Rubrickety]

I misunderstood "Furthest image ever taken from earth" the first couple of times. "But they weren't taken from earth!" Language Is Hard.

[@Q_QQ_Q]

lol

[@CosmosJack]

I watched a SpaceX launch through binoculars last night and the rocket passed right in front of this cluster!

[@diwitdharpatitripathi6782]

Hi Becky

[@tumbleddry2887]

That's the way I've always heard (and pronounced myself) it pronounced.

[@n1k0n_]

BECKY!!!!!!

[@DrBecky]

👋HIIIII

[@iammaxhailme]

Due to people working from home, I've never had so many rapid responses to tweets and emails. That's a silver lining...

[@colinp2238]

Ta dah! The famous Dr Becky. Or is that infamous?

[@Sciolist]

I really thought Dr Becky had uploaded a newer video. Must be a old recording.

[@DrBecky]

Sciolist I still make videos for deep sky as well as my channel 👍 but this was recorded back before Christmas I think 🤔

[@asshatteryengaged813]

Great to see you are still collaborating with this channel like it was back in the day. And also love your new channel - Dr. Becky twice this week!!! 👍

[@Veptis]

Could we get Alan Stern on Deep Sky Videos one day? Maybe for the next flyby? At the rate videos get published here, it may line up.

[@warrengibson7898]

If they had found a problem with the camera could they have done anything about it?

[@bazpearce9993]

Yeah, they build in redundancies, and backups just in case. I think NASA decided to ALWAYS have at least a plan B after Apollo 13.

[@veggiet2009]

I bet with that closer image of the midway cluster you're able to make a more accurate 3d construction of the cluster

[@stntylr101]

These clusters are so far away that they would exactly the same from the Earth's orbit or Pluto's orbit.

[@michaelcollins966]

probably not. as 40AU is ~0.00006% of the distance to M7

[@TannithVQ]

So M7 is like a navigation buoy?

[@chamstrauss]

guys you will do another astronomy videos after messier ones end right?

[@diwitdharpatitripathi6782]

Not machines but humans.

[@fatelvis1473]

monitor and a laptop on a stack of books = science is being done here

[@captainmaay]

Is it possible to 3D position stars in the wishing well cluster when taking a picture of it from 40 AU away ?

[@suokkos]

Parallax measurements use only right angle component of distance vector. This means only small portion of 40 AU distance affects relative position of stars. The best direction to take the photo for parallax measurements would be taking photos to direction which is 90° from Sun.

[@bruceb6529]

the "P" in Ptolemy is silent.

[@davidcocklin2109]

Please can you do Messier 39

[@Thumbsupurbum]

Those poor poor books, behind used to prop up the monitor and laptop.

[@Catsincages]

Surely the 10's would be M10-99? Not that it's my area... Thanks for the vid. 😅

[@WretchMusou]

duct tape seems to be space proof...noice

[@sonnylecrone8468]

I'm 7.. . . . . .

[@iugoeswest]

Cooooool

[@Serebrett]

what's the surname of "I see stars" guy?

[@diwitdharpatitripathi6782]

Hi Dr astronomer astrophysics scientist

[@leyroy1980]

I like to watch these videos so I can feel smart. But have no clue what their talking about..

[@alexmontgomery255]

So M7 was demoted. How rude, lol.

[@larryscott3982]

Love it. A Brit says “a open ...”. BBC would edit that. And wats up with “furthest from ...”? When did “farthest from...” get retired?

[@tscoffey1]

I clicked on this just to read the "Pluto is a planet! A PLANET!" snowflake comments.

[@SoleaGalilei]

I noticed that no one in this video said it wasn't. :)

[@rhoddryice5412]

Something like Klaw-dioz Ptolae-ME-oz would be close to the right pronunciation.

[@Fnortner01]

14th. Ok it kind of loses something after, say, one.

[@biswadeepmandal8268]

First....

[@BIGWUNuvDbunch]

fourth?

[@digetalised]

Second

[@andrewdillon7837]

better third, eager beavers , speaking of beavers,, heres one with a phd,,,who would have thought,,,go figure,,random mysogynist statement,,

[@esquilax5563]

Don't know what the Greeks would say about it, but you pronounced Ptolemy in the usual way for English speakers :)

[@Zheeraffa1]

I'd argue there is no "correct" pronunciation, since _Ptolemy_ is already a garbled form of his actual name _Ptolemaios (Πτολεμαῖος)._

[@SharpAssKnittingNeedles]

How would this be pronounced in modern Greek? 🤔

[@Subzer039]

I guess M5 doesn't exist?

[@graphosxp]

If Dr Becky emailed me it sure ain't gonna take me 2 hours to reply!

[@timbeaton5045]

Yep. Same here. Dr. Becky, are you listening? 😃

[@angusshaw5954]

When Alan Stern writes you back ... 😮😮😮😮😮😮

[@renerpho]

It's "TOL-UH-MEE", with a silent P, and the stress on the first syllable. Your pronunciation was fine!

[@unom9515]

Ptonomy? Legion? :o

[@EvilPOKES]

Love me some Dr. Smethhurst...not gonna lie :)

[@AceHardy]

👑

[@disorganizedorg]

@2:40 -- Steve missed an opportunity to quote 2001: "My God! It's full of stars!"

[@loge10]

I got the impression that he was referencing 2001, he just got the quote wrong.

[@mikel6668]

great video
