i plan on releasing epasode 0 on how to read diagrams

i meant k != 0 im a dumbass

[swift heart]

I would vote for the glorious Ritchey–Chrétien, but I think there is an opportunity to do something unique with that one (explain why the different conic constants are needed to cancel coma)

perhaps that could be explained along with the Dall-Kirkham

[strong hatch]

yup

thats why i havent added the rct yet

it will be complex

i need to script these

[swift heart]

I feel like there may be some satisfying derivation of the formula, but I can't envision it in my head atm

[strong hatch]

instead of taking 1 min breaks between each thought

there were 50 jump cuts in that video btw

[urban quiver]

@strong hatch why

[strong hatch]

you got enough scopes already!!

[urban quiver]

i need more

(i have a 6" dob too)

[strong hatch]

use da moners for something else

[urban quiver]

like what

[strong hatch]

uhh

yes

save it

[urban quiver]

no

[strong hatch]

why

[urban quiver]

i have GAS

[flat wolf]

save for a 6" or 8"

[strong hatch]

save for a 14" ritchey criterion

[flat wolf]

his ragdoll cant handel that

[strong hatch]

ah well

[flat wolf]

a 8" newt will never let you dowm

[swift heart]

I WANNA STEP ON THE GAS

(I relate)

[mint talon]

people vote and judges vote and the winner is decided by coinflip

[plucky vigil]

My god

[flat wolf]

I auto win low teir because I was only low teir so we ball

[strong hatch]

chosen by judges and make me a judge ;)

[strong hatch]

ashen can i submit something to low tier to prevent paint from winning pls

[plucky vigil]

No lol there will be no low tier

[plucky vigil]

No

Wait I’m redoing this yall tryna rig it lmao

[flat wolf]

why

vro I worked hard

[strong hatch]

ah thank god

making it fair

i submitted my low quality submission

its a dim nebula in infrared

[cedar dome]

I submitted nothing since there’s no way I’m getting anything but shame

[flat wolf]

nah, im gonna win best use of equpment

[woeful rose]

Use that dob for AP. Buy tube rings 😩

[urban quiver]

The dob sucks for Astro. It’s a heritage

[swift heart]

This sickens me

[woeful rose]

Oh well 😂 i use mine and i kinda dig it. It’s an 8 inch

[urban quiver]

Ok but the skywatcher heritage series are not suitable for imaging

[delicate lance]

@pliant escarp modified his with 3d printed parts to make it suitable

[pliant escarp]

https://www.thingiverse.com/thing:4914014/files

thats the main mod i did to it, i did some other stuff too though

and i edited that model to have 3 spokes so i get 6-spiked stars

[urban quiver]

I don’t own a 3d printer

And that’s for the 130p not the 150p that I own

[pliant escarp]

you might be able to scale it up if you know your way around 3d modeling software

[urban quiver]

I don’t

And I’m already thinking of selling the heritage

I decided to not buy the 130pds. I’m going mono instead

[pliant escarp]

yeah its not idal if you want to do photography

great for visual though

[urban quiver]

Yea I don’t do much visual… like at all. So I’m just gonna sell it

I don’t have the original box so I’m just trying to sell it to my local club

[flat wolf]

tilt gonna be fine because I know hat im doing, collimation will be baller

[stark hawk]

IF TOMBAUGH NAMED open clusters why would anything else be better?

[limpid geode]

Pretty sure this is on topic

[lofty jetty]

Under 50k ly doesnt mean that its not under 1

[limpid geode]

Sure

You know what I mean

Between those orders of magnitude

[lofty jetty]

In all seriousness I dont know so its best if I dont vote

Even a guess might be very wrong

[limpid geode]

It's not supposed to scientific

[lofty jetty]

But if i had to guess, somewhere between 100 and 1000

[limpid geode]

Ok

I'm hoping for under 100 light years

Probably likely about 300 parsecs, that's where all of the seti candidates are and the result of the statistical drake equation

twas just the first space related album that came to my mind

[cedar dome]

Get either AM or My Favorite worst Nightmare by Artic Monkeys (I’m only sayin this because british )

[strong hatch]

artctic monekrrt is slightly mid

thats volume one of my youtube playlist

[cloud stratus]

[cedar dome]

Someone said this sounded like the Arctic Moneys and I can’t get it out of my head 😭 😭 😭

[strong hatch]

i does 😭

ot really does 😭

[cedar dome]

Honestly I revisited my favorite worst nightmare, and some songs just hit different for some reason

[strong hatch]

[cedar dome]

The bad thing is a really underrated song, imo. I don’t pay attention to the lyrics though because 🙃

[strong hatch]

i recently re listened to the album painkiller again after not listening for a while on a record player and it sounded deeply scrumptious

https://music.youtube.com/playlist?list=OLAK5uy_ljou0AcM2Lu1y42rPN0Z4pePVp12Z6brs&si=tbOUv3Fo39s3tm6F

…most likely tomorrow since it is late lol

[strong hatch]

2 am is not late!!

[obsidian plover]

Dark side of the moon

Or brothers in arms

[strong hatch]

i love how no one has actually chose an option

the entire point of a poll is to be quantitative not qualitative data 😭

i will be getting countdown to extinction if the poll doesnt change

[obsidian plover]

Cuz bad options 😭

Dark side of the moon is a must

[strong hatch]

bad options???

the entire point is that its what i listen to

also im 80% sure you havent listened to any of them

😭

[obsidian plover]

Indeed, therefore I cannot vote or something I haven't heard

Someone else said dark side of the moon 🔥

[strong hatch]

im not going to go out my way to buy a record for a band i dislike or havent heard of

[strong hatch]

you tried to vote by saying some irrelevant album 😭

[obsidian plover]

Ain't no way the 3/4th best selling album of all time is irrelevant

[strong hatch]

irrelevant to the poll

also tbh something i have never heard of is also irrelevant to my life 😭

[obsidian plover]

why’s this even a question

[urban quiver]

cause I really couldn’t afford it

[cerulean elm]

Ypu went from color to mono. Big upgrade

[urban quiver]

but I have no money now

Half a meal a day now

[cerulean elm]

Save up

[urban quiver]

food 🙁

[cerulean elm]

Ooof. Then don't rush

[urban quiver]

I already bought it

[cerulean elm]

💀

[urban quiver]

EFW and filters come tomorrow

camera is still in China

[woeful rose]

make it 1/4 th

[urban quiver]

So that means I should buy a 8” newt….

[woeful rose]

Like me yes

[swift heart]

As a Touptek ATR533M owner... it's worth skipping a meal over tbh

@urban quiver I can also recommend camera settings for you

[urban quiver]

cool dm me them pls

Isn’t there different modes? Like some weird dynamic range specific mode?

[swift heart]

I use high full well, high conversion gain, low noise (ultra) mode, gain 200, offset 256, and that gets me unity gain and very low noise

[urban quiver]

NINA?

[swift heart]

Yup

[urban quiver]

I didn’t realize there’s so many settings

Idk even get full well tbh

[swift heart]

I just picked those settings after doing some camera tests for unity gain and just using the graphs for finding minimum noise

[urban quiver]

Do you use the bundle’s EFW and filters?

How are they

[swift heart]

Yeah I got it as a bundle. I can't make any specific comparisons between filters for mono cameras, but I will say the OSC > mono switch is astounding especially when you get to narrowband targets

[urban quiver]

Do you get any halos? I’ve heard Oiii will halo a bit

[swift heart]

Not anything that's caught my attention. But I haven't imaged, say, the Flame Nebula to really test it

[marble hearth]

Wasn't unity gain 100? Also why such high offset?

[swift heart]

Not for the ATR533M in HCG/HFW/LN mode. I did the sensor analysis myself with Poisson noise.

You do not want to run the camera at gain 100 in that mode; the well fills before the sensor saturates

I'm sure I could lower the offset, it's just the default value

It's still half that of a DSLR

[marble hearth]

Gotcha, I might have to try ur settings too then

[swift heart]

M40 is the best nebula

[flat wolf]

now how much they cost lol

[strong hatch]

£40-60

[flat wolf]

do mirrors even reflect it

[strong hatch]

yup

you act like i dont do wayy too much research

[tribal coral]

is that like the opposite of SWIR?

[strong hatch]

its just deeper swir

like 6-15um

[pliant escarp]

it goes
SWIR
MWIR
LWIR

ig you can add NIR to the beginning of that (and far infrared at the end)

SWIR and MWIR sensors use the photoelectric effect to "see" while i think some LWIR sensors are essentially just a matrix of tiny thermocouples lmao

[pliant escarp]

dont quote me on that though, might be totally wrong 💀 but however it works, thermal cameras fall into the LWIR range (looked it up, yes, they use "microbolometers", so not traditional sensors. a small part of it heats up and it causes a change in electrical resistance. its a thermocouple. so you dont need cryogenic cooling like you would with with a sensor that uses the photoelectric effect at those wavelengths)

the atmosphere becomes opaque at wavelengths that long though

https://upload.wikimedia.org/wikipedia/commons/thumb/9/92/Atmosfaerisk_spredning-en.svg/3840px-Atmosfaerisk_spredning-en.svg.png

i didnt remember the transmittance picks back up that fast (at the 8um mark)

but theres a huge gap there from 5-8 in the middle of the infrared spectrum (disregarding very far infrared)

[delicate lance]

they dont

gold does

but not normal aluminised mirrors

or wait

lwir

not mwir

nbm

nvm

[strong hatch]

[pliant escarp]

this sensor architecture makes me think its gonna have like laughably low QE

thats just a blind guess though

[delicate lance]

It goes NUV VIS NIR SWIR MWIR LWIR FIR

from shortest to longest

[pliant escarp]

tried to look up info on its sensitivity, but its uhh complicated

however i found this

so basically your background is brighter than most anything in the night sky, and it varies a lot even during a second

also its not even consistent across the sky. so you have like a complex bright light pollution gradient that fluctuates very quickly across the entire sky, in AP terms, lol. that is, if im understanding this correctly

https://link.springer.com/article/10.1007/s10686-021-09744-6

[strong hatch]

i know

[pliant escarp]

she knows

[strong hatch]

i will even have to deal with my mirrors heat getting picked up

[strong hatch]

luckily for that i can slap the dust cover on and get pseudo darks to remove that

tbh if i can just get the orion nebula i will be happy

[pliant escarp]

sensitivity limit of -2.8mag on a 1.52m mirror 😭 i have to be reading this wrong

[strong hatch]

uhh

i do not think that is right

im sorry to say

[pliant escarp]

they had a 1.52m mirror as i said

and they were able to detect 1 single object at 11um with a microbolometer (EDIT: 10 objects of 13 candidates. even the star vega is too dim to see with this system)

ok yeah the -2.8 had to be something else, this carbon star has a magnitude of 7.7

https://en.wikipedia.org/wiki/CW_Leonis

so basically their system is able to detect the very brightest carbon stars in the sky

[strong hatch]

[pliant escarp]

i mean tbh itd be cool as hell to detect them still, thats something

here is the detection

[strong hatch]

thats hawt

[pliant escarp]

they did this "chopping and nodding" routine, i didnt read too far how it works

[strong hatch]

i see

[pliant escarp]

but it allows you to remove any spatial and temporal variability from the sky background

[strong hatch]

ohh

[pliant escarp]

its here if you want to read more

[strong hatch]

i think thats sorta like how planetary works?

[pliant escarp]

interesting read tbh i kind of wanna look more into it but i gtg now

[strong hatch]

yk how you take the bests parts of each video and mash them together

[pliant escarp]

uhh kinda, there youre trying to catch glimpses of good seeing in select frames/parts of a frame

[strong hatch]

but instead of seeing its for heat pollution

[pliant escarp]

here its more like you get 2 stacks with ""bad seeing"" and you can substract away anything that changed between them

that or im totally misunderstanding this, which is more likely

[strong hatch]

oh yea

[pliant escarp]

https://link.springer.com/article/10.1007/s10686-021-09744-6

wtf

ok should work now

[strong hatch]

no, i was sensing a screenshot of imgr

imgur is banned in the uk

[pliant escarp]

oooh

[pliant escarp]

WHAT

cant have shit in the uk

[strong hatch]

ohh they tilt the secondary quickly to basically get 2 pictures that are at on and off axis so you can just get the target

then they go to a diff pos and get rid of the exess left behind

[pliant escarp]

mmmmm

right

[strong hatch]

thats complex af

i gotta frigg my collimation to do this ig 😭

[pliant escarp]

yeah and you have to do that within like a minute because the temperature change of the telescope will mess it up otherwise

[pliant escarp]

🤣

[strong hatch]

i can luckily to do the second part i can just disengage and manually slew

[pliant escarp]

mm yeah maybe

[strong hatch]

what i can also do is try drift scanning

[pliant escarp]

i mean if you manage to detect any infrared source, hats off man

[strong hatch]

the sensor i plan on getting has a max exposure of 4 seconds

[pliant escarp]

cool project in anycase tho

maybe you can do some funny terrestrial observations if the sky is too bright to detect anything

oh also, you cant use any glass elements but you probably already knew that

gotta be like germanium lenses or some even funkier stuff. but best to just rely on only reflective elements

[strong hatch]

ik about germanium lenses yea

[pliant escarp]

germanium coma corrector :D

[strong hatch]

class cass:

then i wont need germanium

[pliant escarp]

i mean correction doesnt really matter

youll be detecting point sources

[pliant escarp]

suomi mainittu, torilla tavataan

[strong hatch]

its quite old yea

[strong hatch]

wha

[pliant escarp]

not what i was pointing out

finland!!!

also quantum dots are sick, didntt know theyd be able to be used here too

but! i thought quantum dots only did down-conversion

https://pubs.acs.org/doi/10.1021/acs.jpclett.4c03559

this is nuts!!

i wonder if this is what they used for those infrared sensing glasses/contacts

ok now i NEED one

[strong hatch]

they use a material that knocks the ir light into the visible light

but in the process you loose a lot of resolution

so everything becomes fuzzy in ir

visible light gets less effected

[strong hatch]

no wonder the atmos is so bad for ir

like 99% absorbtion from the water

[pliant escarp]

yeah i think thats the reason for the 5-8um gap

but the other big issue is thermal currents

[strong hatch]

water vapour is the main issue for any ir imaging

[pliant escarp]

yeah but arent there gaps that water doesnt absorb?

[strong hatch]

oh ur talking about that gap

[pliant escarp]

like so much so it has better transmission than it does for visible

https://images-ext-1.discordapp.net/external/SK7h8Y0ndiJPjc-lRhxzR-ZqC5tnbPIhae9sqdjByxg/https/upload.wikimedia.org/wikipedia/commons/thumb/9/92/Atmosfaerisk_spredning-en.svg/3840px-Atmosfaerisk_spredning-en.svg.png?format=webp&quality=lossless&width=2512&height=1226

[strong hatch]

ohhh i thought you meant the 5-8 gap

as in 5-8 gap in transmission

[pliant escarp]

i mean i was here

but 3-4 and 8-13 are pretty good

8-13 you hit the thermal current issues though

[strong hatch]

lwir moment

widefield of the sky at 850nm

i found a use for the 9million lenses i own

@pliant escarp do i do more widefield shots out my window on partially cloudy nights?

[pliant escarp]

oo cool

[pliant escarp]

yea sure

is this with an astrocam?

[strong hatch]

yup

[pliant escarp]

mmm, you dont happen to have 2?

even a dslr + astrocam might work, just 2 cameras that can take (ir) filters

[strong hatch]

2 cams or 2 filters?

[pliant escarp]

both

[strong hatch]

i have 2

[pliant escarp]

attach them to like a dovetail, different ir filters on each and use nina or something to trigger exposures on both at the same time

then try your best to overlay them in post

[strong hatch]

why am i doing this may i asl

[pliant escarp]

2 color ir camera!!!

this is RGBI

i tried to map them like this

it was a pain to take 2 images from the same perspective and overlay them correctly though, had to swap the filter and i didnt have a tripod (used eq mount, hence the weird ass framing, lol)

[swift heart]

Would it be feasible to try astrophotography with this camera

[pliant escarp]

dont see why not

could just throw 2 different ir pass filters into a filter wheel atp though

[swift heart]

I'd love to get 700-800 and 800-900 IR pass filters to complement RGB

Perhaps I can just get Sloan i' and z' filters for that purpose

[pliant escarp]

yeah

i wanna do more with even just my 685 pass, ive only done 1 astro image with it

[strong hatch]

considering i get like 1 to 0 hours of astrodark during summer probably winter or spring

[cloud stratus]

The idea is that it’s independent of imaging conditions like astrodark or weather. Solely based off the overall quality of the available targets

[strong hatch]

yeaa summer is mid

summer has cyg tho

[flat wolf]

they are the same, so this is unfair

all pne are emmison nebulae

[delicate lance]

yup

[cloud stratus]

43% of you are horrible people

[delicate lance]

Those who don’t vote for PNe just lack focal length!!!!

[rain void]

And those who do must live on the moon!

[strong hatch]

PNe are just emission nebula

pne fall under emission nebula

[cloud stratus]

you know what I meant. Hii regions

[strong hatch]

oh, in that case

PNe all the way

[cloud stratus]

me when I lie

[strong hatch]

have you ever looked at a pne before

[cloud stratus]

yeah

[strong hatch]

with your own eyes through a scope

[cloud stratus]

yup

a 16 inch dob actually

[strong hatch]

and you say you dont prefer pne

[cloud stratus]

yeah cuz i also care abt imaging

[strong hatch]

tf fl r u using

[cloud stratus]

250mm and 750mm

[strong hatch]

ah

[cloud stratus]

emission nebulae have fun structures at literally any FL tho, PN are more limited to high FL (or ultra deep exposure in the case of old PNs)

PN are better through visual scopes, but you can still see emission nebulae visually and emission nebulae or more accessable to literally any FL

so I think emission nebylae are a better target overall

[strong hatch]

yk whats better than both

galaxies :3

[cloud stratus]

visually yes

[summer turret]

yet to see galaxies visually through a scope

[strong hatch]

imaging wise

[cloud stratus]

nah, they lowk galaxy schmalaxy

[strong hatch]

they look spiral

[cloud stratus]

I saw m81/82 through a 10inch dob yesterday

wait not yesterday, saturday. I'm just making up dates

[strong hatch]

could you see the m81 spiral?

[cloud stratus]

yeah i could see the 2 biggest arms

[strong hatch]

basically yesterday

[cloud stratus]

yeah

[strong hatch]

i could only see one of the biggest arms w my 6" :(

[cloud stratus]

i had 2.3x (ish) light gathering compared to u is why

[strong hatch]

yea, its insane

[cloud stratus]

anyway, IMO unless you are imaging mergers or other weird galaxies, they are all far less unique the SNRs or emission nebula

arp catalog >>

[strong hatch]

i need 50k to get a good mount + a 500mm class cass fr

[cloud stratus]

I will love galaxies once I have a planewave or ASA and I can image the arp catalog

[strong hatch]

what size planewave u want?

[cloud stratus]

haven't gotten that far yet

its not on the table for many decades, so why decide now when the market could change an incredible amoubnt

[strong hatch]

true

in that time planewave may even become irrelevant

[cloud stratus]

exactly

[flat wolf]

tea, can you check auric server, I have a question idk if you know anser

[marble hearth]

Star trails only look good w a good foreground

But when they are good, they are stunning

[marble hearth]

what tripod u got rn @fallen obsidian ?

and what mount

[flat wolf]

its some random one, its not great, but its stable

[flat wolf]

ragdoll 17

tbh, one of the main things that discourages me from astro is the amout of things I need to do to be able to image, so automation would be very helpful

kstars is very annoying

[marble hearth]

no yeah minipc saves so much time and sleep

[flat wolf]

also if you reccomend a mini pc, which one

[flat wolf]

this is one of the main things that I prioritize in asto

[marble hearth]

any 2nd hand one would work, i personally got the mele 4c quieter, but from what ive heard, fans dont disrupt that much so it could be worth getting one w fans for slight increase in performance

[flat wolf]

I dont really care too much about preformance, I just want ease of use, also my budget is around 200-250

[marble hearth]

or actually on 2nd thought i think its windows thats just SO slow sometimes

[marble hearth]

thats plentyyyyyyy for a minipc, i got mine new for like 150 usd

idk about these days w the ram prices lol

@woeful rose this mfer keeps getting free minipcs and RAM sticks somehow

[woeful rose]

I've gotten the beelink s12 mini. Works great. Upgraded it with some free storage. It has 16 gb ram and 1tb storage now lol

[woeful rose]

I have 2 480GB and a 60 gb SSD laying around. Also 2x 8 gb sodimm ram. And imma get another free laptop and maybe a pro desk for parts.

[flat wolf]

what about the pro

[woeful rose]

Yeah I think it's the pro. You need w11 pro to do remote desktop.

It draws at best 36 watts so for remote imaging it's not bad at all

[flat wolf]

how would I use a minipc and not do remote imaging

[woeful rose]

Idk.i don't know

[flat wolf]

dont you use a s12?

[woeful rose]

Yes on my Redcat rig. On my newt I just use a elite ook 😭

😭

[flat wolf]

so you do remote on your redcat?

[woeful rose]

I mean if u mean remote like the cat goes outside and I'm going inside to my PC then yes.

[flat wolf]

why cant I do it with the s12

[ivory mural]

(do not pay for w11 pro)

[summer turret]

if you've got home, then you can use chrome remote desktop

[ivory mural]

i use rustdesk

i have pro but i honestly prefer rustdezk

[woeful rose]

That's fine to use.

[woeful rose]

You may can. Idk the difference between the pro and not pro. Maybe it's storage and ram and maybe a n150 instead of n100? Idk

[ivory mural]

i have to vote for the one with my name in it

[urban quiver]

Until they find aliens yes

[limpid geode]

They're bad at finding aliens

Too anthropocentric

[marble hearth]

Had a spare guidescope and cam, so putting the two to the test

[urban quiver]

What kind of question is this…

[marble hearth]

https://cdn.discordapp.com/emojis/1361035348104450068.gif

[rain void]

what sensor size?

[flat wolf]

585, so 11.2x6.3

[rain void]

ig for PNs the choice is obvious

because the fov doesn't really matter

[flat wolf]

its one of the best tbh in terms of readnoise and qe when sensor size does not matter

[rain void]

what is?

[flat wolf]

the 585

[rain void]

oh yeah

[flat wolf]

not counting the 462 read noise

[flat wolf]

its got like 85 qe in ha

and 91 in oiii

[rain void]

read noise is pretty much irrelevant for long exposure AP, so you're just looking for QE

are you choosing between reducers?

[flat wolf]

at 3nm it prolly affects more than broad band but its prolly still negligable

[flat wolf]

its f/4 vs f/5 and 1x vs .95

[rain void]

if you're strectly going for PNs, all that matters is the aperture, the QE, and the sharpness of the optics

assuming you have enough FL to not be undersampled

and slower optics are usually sharper

[flat wolf]

because your the expert, is a stellalyra 4.5 + nexus a bad idea, i dont really care about the collimation standards and I know it will be able to focus

[rain void]

your image circle is getting nuked

[flat wolf]

its got an oversized secondary and im using a 585

[rain void]

yeah with the 585 it's no problem, but it will be too small for apsc, and probably noticeable at 1" square like a 533

[flat wolf]

with the reducer or just native?

[rain void]

with the reducer

[flat wolf]

yea, so im fine, I have no intentions of upgrading my sensor

[rain void]

well, then i see no problem with it

[flat wolf]

yay

bout to have a crazy semi travel rig

and widefeild

[rain void]

it will probably be like a slightly blurry epsilon

[flat wolf]

the takahashi one?

[rain void]

ye

[flat wolf]

also why slightly blurry

[rain void]

glass

also a nexus is 700eur???

[flat wolf]

no it is not, it was 400 bucks

[rain void]

fair enough

[flat wolf]

which is like 200 euro idk

[rain void]

huh

400 usd?

that's not 200 eur m8

[flat wolf]

idk

[ivory mural]

⁉️

[flat wolf]

vro idk, markets have been changing recently

[ivory mural]

not anywhere close to the point of 1 eur being 2 usd

[flat wolf]

yea

[flat wolf]

the dollar got stronger ig

[flat wolf]

wanna join ashen club

[ivory mural]

no

im not having an ashen identity crisis or whatevers going on

[cloud stratus]

what's your bortle? How does 4.5nm vs 3nm actually matter for you? Can you get a reducer?

[flat wolf]

im prolly gonna get 4.5 so I dont have to get extra filters for my f/3, bortle 7 btw

[cloud stratus]

lowk just get the f/5 one and then add a reducer if u want

[flat wolf]

good idea

@strong hatch @woeful rose 🥀

i forgot my sv305 was osc

anyways, 3 hours 50 something minutes of 3 min subs

with meh conditions

oh and the 533 is cooled to -10 and the sv305 isnt

[cloud stratus]

Nope

[strong hatch]

left is so much sharper

[marble hearth]

Yeah maybe has sharper noise 🥀

[strong hatch]

right looks so much better

wasnt even a fair fight

[marble hearth]

Here's 4hrs of osc vs 1 hr of mono to make it a bit more fair

[strong hatch]

right is still soo much sharper

[marble hearth]

I sure do hope so 😭 better optics and mire efficient sensor

Gonna compare the osc again w 4 hrs total of rgb w mono once I get that

[flat wolf]

ok chat, yall decided

[obsidian plover]

If it's a good comet like G3 it's better

[swift heart]

Transients always beat non-transients IMO

[marble hearth]

4 hours of OSC vs RGB mono (1.3hrs of each filter)

[rain void]

ok but please cc the OSC for a fair competetion

[marble hearth]

I tried but it turned so blue 😭 😭 Either way, it's clearly more noisy

[rain void]

ah fair enough

[flat wolf]

what about one combined with a planetary nebuale

i guess ill just do mini 5-10 hr projects for the others lol

[rain void]

doesn't know what to do
asks for other people to decide with a poll
everyone unanimously votes for the same option
does something else

what

[flat wolf]

i never said I would not shoot cresecent and soap bubble for 30hrs lol

[rain void]

Fair enough

[flat wolf]

vote in filter poll

[rain void]

Isn't f/3.7 a little fast for 2.5nm?

[flat wolf]

the antila is shifted a bit afaik

I cant find a 3nm that will comfortably fit in it

[rain void]

I thought they should be shifted to the left? I guess not

[flat wolf]

3nm also does not have a flat top

[rain void]

Goofy

[flat wolf]

yea, so it between spending 1k for 97 percent transmission 2.5nm, or 400 bucks for 90 percent 4.5nm

[rain void]

2.5nm will cut the LP by 44% tho

[flat wolf]

bortle 7 btw

[rain void]

you will need slightly more than half the time to get the same SNR with 2.5nm as with 4.5nm

[flat wolf]

I mean it does fit with my intrests of really dim pne but it hella expensive

[flat wolf]

even when you account for the 7 percent more transmission?

[rain void]

oh yeah that makes it close to half the time

it makes your rig a whole stop faster for just 600 bucks

in that perspective it's actually qutie cheap

[flat wolf]

i mean I could sell my starizona idk

[rain void]

nexus?

[flat wolf]

yea

[rain void]

ig

can't use both at the same time anyways

unless the filter comes before the corrector

[flat wolf]

can you calculate it

[rain void]

calculate what

[flat wolf]

55mm backfoucus, its parafocal

[flat wolf]

vigetting

[rain void]

no

it depends on the size of the secondary and the width of the image train i think

but also optics can make it weird

[flat wolf]

I dont think it woould work

[rain void]

what wouldn't work?

[flat wolf]

filter in front

[rain void]

oh yeah that was just a joke lol

[flat wolf]

lol

[strong hatch]

they should be

[rain void]

then whats going on???

[strong hatch]

idk :(

fast scope does a blueshift

so you have to redshift

[rain void]

wut

[strong hatch]

to compensate

[rain void]

but wouldn't you have to blueshift, so you filter out the slightly blueshifted line?

[strong hatch]

do i do a bobjones drawing

[rain void]

yes

ohhh the transmission curve gets blueshifted

i was thinking the light got blueshifted

[strong hatch]

amazing drawing

[rain void]

https://giphy.com/gifs/netflix-d31vTpVi1LAcDvdm

[strong hatch]

that would be impressive

thats how you know you got a fast scop

[cloud stratus]

Fuked up the last poll by accident

[ivory mural]

great comet or an average comet

[cloud stratus]

doesn't matter. It's just about the target in general, cuz there are also some galaxy clusters that are really far away and 1arcmin in diameter that are kinda lame

It's your choice if you wanna compare the best of each target, the median, or the floor. idrc

[ivory mural]

i ask because a great comet beats a good galaxy cluster imo but a shit galaxy cluster beats a shit comet

[cloud stratus]

you choose how you wanna vote

[ivory mural]

i guess if we go by average, average comets aren't very interesting

[cloud stratus]

When I chose, I was comparing a A6 (Lemmon) vs. Virgo cluster type of thing

but other peiople gotta choose what they base their vote off of

[obsidian plover]

Hydrogen bomb vs coughing baby question

[strong hatch]

those are some of the best

[marble hearth]

yeah idk ppl r opinionated about this, honestly as long as it has overall good reviews, its returnable, and has a decent warranty policy

u can ask here

https://discord.gg/3dprinters

they have a channel for buying

[low lance]

Me and my friend have the bambu P1S and it's really good if you have the money for it buy that instead of something cheaper the price is worth it

[urban quiver]

I bought a Qidi Q1 Pro

The P1S looked good but apparently its older and lacks some modern features.

[low lance]

Oh alright

[urban quiver]

Q1 pro is a bit cheaper so that’s really my main reason

Also better for PETG-CF apparently which I do want to print

[low lance]

But the P1S is like 600 the Q1 is 1000

[urban quiver]

Uhh no?

P1S is $400, and the Q1 Pro was $375

[low lance]

At least from what i saw of just looking it up in 2s

30€ for me filters for my newt, binoculars (double as filters for my camera lens), and eclipse glasses

[marble hearth]

Film sharper than glass??

[marble hearth]

Film for newts, glass for fracs

I tried both w my telephoto lens, and only glass seemed to let through true white light, film looked orangey ish

[normal fox]

yep i knew it

[normal fox]

yet another flat earther accusing me of a logical fallacy whilst they themself are using a logical fallacy

[pliant escarp]

I was surprised too, browsed around on the web and yeah apparently film is generally sharper

Some high quality glass ones can apparently be better?

The film is just so thin that it doesnt really distort the light much. Also if there are no wrinkles, that is a sign its probably too tight, and that apparently can introduce distortions... All this just from some quick googling so take it with a big grain of salt

[leaden copper]
