Oh my God

#

also, why sedna before Pluto?

#

No one has ever taken a picture of it on the server

#

Oh

#

But still, it’s an incredible image

#

What about Makemake?

novel panther
#

That is crazy

#

Don’t think I have ever seen someone image sedna

#

Nice!!

#

Yea

cerulean fiber
#

Try capturing Sedna in 6000 years

novel panther
#

Really cool congrats

#

Now we need Pluto image Muehehe

cerulean fiber
#

Haumea.

novel panther
#

There is no Pluto here too

#

In this server

novel panther
#

Oh damn

#

Really wish I could do Pluto but with my small frac there’s no chance

#

Awh

#

250mm?

#

I’m pretty sure u need more even for a dot?

#

Is lucky imaging used for this sedna pic?

cerulean fiber
#

What about Hyperion?

novel panther
#

Okay lmao

#

Mb

#

Yep I knew

#

Wait, u meant possible?

#

I have 2 inches of aperture

#

Wait u said 1m

#

Lmao

#

.

#

I know that

#

I have seen yt vids about it

#

It’s like a small faint tiny dot

#

Ah ok

#

U think I can resolve it? Especially in my b9

#

51/250 frac

tepid mountain
#

do you think tw astro could resolve it?

#

mb i meant detection

#

could you even do it at only 8" of apeture which would be insane

cerulean fiber
#

Yes

tepid mountain
#

oh dang

cerulean fiber
#

No way can I have the picture please?

tepid mountain
#

i mean that makes sense since uranus rings are very dim while uranus isnt

#

while pluto is what i would guess 2x brighter than charon

#

idk that was just a guess

#

yoo that's a đŸ”„ image

cerulean fiber
#

Wow

#

What do you think I could image of a 4 inch telescope?

tepid mountain
#

do you have a Ha narrowband filter?

cerulean fiber
#

No

tepid mountain
#

sorry i was talking to yoships

cerulean fiber
#

Oh

#

Sorry

#

Gtg cya

tepid mountain
#

did you ever try imaging ngc 604?

#

ahh

#

what bortle?

#

not THAT bad but yk still not very good

#

you could maybe try?

#

lucky imaging even at 1 second probably is impossible on that but at like 10 seconds i dont see why not

#

you wouldd just need way more data

#

gah damn thats a beast

#

bruh i just realized my touch pad on my laptop stopped working :(

#

probably because of dew getting on it

#

With some interferometry it could be cool

#

C'est sûr, mais c'est fun !

#

The simplest method is to make a mask with two holes for a fizeau interferometer but there's better methods with specific patterns to optimize resolution/light gathering

#

I might try it during the next full moon on some double stars

#

It can't get past the resolving power obviously but it better handles seeing

#

It's made in such a way that resolution is basically the same

#

And the diffraction pattern is actually what you want

#

I'll send you ressources later

queen mirage
#

If it's really large maybe but the idea is to take the inverse fourier transform of the diffraction pattern to get the object that created it so it better be big enough

#

Quite an extreme example cause they have a 200" mirror

#

But it's crazy to see the binary pop up

#

The challenge would be adapting it to optical small aperture telescopes, i've been thinking about it for a while

queen mirage
#

I don't think it's enough (tho worth a try) as the maximum separation sits just above my scope's maximum resolution which means it should be doable with lucky imaging if they weren't so dim

#

Because of their brightness adaptive optics or speckle imaging are a must I think

#

That I'll definitely do!

#

Well if it's too dim we might have troubles aligning

#

Uranus is a bright reference to align in this case so it's easier

#

Its worth a try anyway but I'm not really optimistic about it

#

Nope j'ai fini ma journée

#

A group of amateurs actually managed to capture charon after several attempts with a 14" so it might actually be possible considering the crazy resolution for your aperture

#

Hehe vive l'université

#

Oui j'ai sauté une classe

Donc je vis ma meilleure vie en licence parcours spécial (meca ato maths, que du fun)
