[obsidian plover]

my rig just has all the cords always attached so i dont need to plug in much

does look quite messy tho

[low lance]

I wish i had a backyard that i could just leave my setup and not have to take it down everytim

[cerulean elm]

I'd rather drive to the remote area earlier and take my time setting up rather than rushing and spending the whole night troubleshooting

[cerulean elm]

Is that JB-weld?

[marble hearth]

5 minutes to get everything out and plug everything in, 10-15 minutes of PAing 😭

[rain void]

10 minutes of getting the telescope out, plugging cables in, connecting, balancing.
0 minutes of PA because pier.
0 minutes of choosing target because long projects.
0 minutes of rough focus because I store the camera already on the scope and pretty much in focus from last time.
0 minutes of setting up the sequence because it's identical each night on the same project, so I just load it.

Maybe 5 min of focusing, cooling and slewing, but that's all part of the sequence so it doesn't count lol

[marble hearth]

and then 43200 minutes of waiting for clear skies, of course

[zealous cloak]

you dont have to worry about humidity? because i guess the mount is out 24/7

[rain void]

I just use a telegizmos and it works phenomenally

The mount is always dry when I pull it off, even in humid af weather

[zealous cloak]

i should invest in one but i dont trust leaving my mount out on a tripod

i guess having a pier is the minimum to be completely sure u wont find the mount kissing the ground

my main issue is during summer, the floor on my backyard is covered in tiles and they heat up like crazy when the sun is up and its 42ºC outside

and all that heat is radiated up to the mount

[rain void]

My god i wouldn't trust having anything outside in that hot weather lol

[zealous cloak]

yeah... i wish my backyard was just dirt, the heat wouldnt be that intense

[rain void]

Idk if heat will actually damage anything tho

[zealous cloak]

it would definitely melt the grease in the mounts mechanisms

[rain void]

Not totally sure about that tbh

I can only find people online saying it should be fine, but no one who has actually had their mount damaged by heat

[zealous cloak]

hmm

[rain void]

Basically mounts are a lot less problematic than optics

[zealous cloak]

yeah the scope and imaging train would stay inside

[lofty jetty]

Sometimes 2 hours

[brisk copper]

this is going to be the first section

[silver holly]

Mine is almost too hot to touch under the cover most days. It’s fine. Been out for over a year now.

It’s rusty and whatnot because it gets lots of salty air on it at night but otherwise completely fine.

[zealous cloak]

Ah okay

Well then I guess ill invest in one for the summer, as here its typical to have long streaks of clear. Setting and packing everything up every night is exhausting

Also no salty air

[silver holly]

The pier is the single best bit of kit I own.

Tripod works I guess but i didn’t have space for it.

[summer turret]

ngl focusing manually at f/2.8 is quite tricky

[zealous cloak]

Depending on if I go remote or not ill consider building one

[obsidian plover]

[zealous cloak]

Praying the mount doesn't go crazy

[undone sinew]

Move telescope and equipment up 2 flights of stairs (20 minutes)
Setup the telescope (3 minutes)
Find and focus on the target to image (25 minutes)

[delicate lance]

no telescope setup takes 3 minutes vro, polar alignment aint that quiick

[undone sinew]

What’s polar alignment?

I just put it on my crappy untracked alt az mount and pray it doesnt randomly tilt and fall over

[fallen obsidian]

move telescope to balcony, 1 -2 mins
connect everything, 1-2 mins
polar stuff, 4-6 mins

[brisk copper]

you actually do ap??

[brisk copper]

you dont dither so you cant speak

[fallen obsidian]

im trying, im sorry

[vagrant basin]

Bruh my mount bubble level is broken but when I use my phone to level I forget it has a camera bump so its a long day🙏🏼

[urban quiver]

why do you need to level your mount

[vagrant basin]

Part of polar alignment right

[urban quiver]

doesnt have to be

just makes it easier

[vagrant basin]

Fr???

Damn I didn't know I always adjust the height against 30kg of equipment

[urban quiver]

If its not level it just makes it harder

since if you adjust it right you may need to make it go up or down or whatever

so going one direction will affect another

[vagrant basin]

I see yeah then you would have to adjust the other legs

[urban quiver]

no another ALT AZ not the tripod

[delicate lance]

Uncoated? Yuck

[delicate lance]

Wait I need some context

Is it FULL FPL-53??

Or is one element FPL-53

Send a link to either please

[undone sinew]

Yeah but it’s like a really crappy, difficult version of ap

[brisk copper]

full

[brisk copper]

its a hypothetical, i dont have either

(dont have schematics either)

[delicate lance]

FPL-53 has superior Chromatic Correction but for full correction you need a combination of FPL and BK 7

it reflects around 4% of light without coatings, given the 5 elements youll be loosing way too much light

20% light loss (or even more!) + internal reflections vs a good coma corrector with slightly more CA, the answer is clea

[brisk copper]

i know

[low lance]

Idk polar alignment isnt hard per say it's just more time consuming because i dont have access to Polaris i have to do TPPA manually and i have to redo it multiply times to get accurate alignment for focusing i have a bahtinov mask so it only takes less than 40s and collimation i have a laser collimator so again only takes a few minutes but TPPA can easily take 20 minutes from my me along with a further 5 for calibration of the guide setup

[low lance]

Aperture fever goes hard

[bronze minnow]

think abt it

if no moon
no cheese

no eclipses

no funny occultations

[cerulean elm]

You forgot that the days will be much shorter, Tides will be almost non-existent, ocean currents will be altered which as consequence will absolutely destroy ocean life, Earth's axial tilt will become unstable, seasons will become chaotic, advanced life nearly impossible. You want the moon

[bronze minnow]

those too

but no cheese is much more important

[silver holly]

Replace the moon with a sphere of equal size and mass that is made from vantablack.

[cerulean elm]

Oooor. Paint the moon. it would be more plausible. Actually you only have to pain half of it.

[lofty jetty]

Yes

We still get solar eclipses

But no more bright moon

And the media can shut up about the endless supermoons

[swift heart]

Yes but none of this is as important as astrophotography

[swift heart]

Actually you would want to paint 60% due to libration

[woeful ivy]

black hole mass moon

[brisk copper]

terminal is basically just a digital tty

[woeful ivy]

north and south

[marble hearth]

Fun fact the moon is already as dark as asphalt, so it's already pretty unreflective

[cerulean elm]

And yet... during the day you can see the asphalt and the moon. So the sun is the culprit

[marble hearth]

Yep, blow up that bright ass fusion furnace

[low lance]

What if we just painted the moon black

[low lance]

Idk asphalt isn't even that black especially weathered down asphalt

[marble hearth]

Doesn't rain on the moon

I mean it's got an albedo of 0.12 and we still see it in daytime

[cerulean elm]

But you have a healthy lethal dose of radiation every day

[low lance]

There is still a tone of solar radiation which bleach colors

[marble hearth]

Sun can't bleach rocks..?

[low lance]

Also if you look at lunar images taken by Apollo the color of the moon is grey similar to that of weathered asphalt

[marble hearth]

Healthy lethal.. Hmm

[low lance]

Yeah those x rays and uv rays can bleach anything

Well change their chemical composition which in turn changes their colors

[marble hearth]

Hard to tell the darkness of the surface from the photos.. But yeah samples taken back to earth do look like a grey between concrete and asphalt

[cerulean elm]

So it will make it more reflective.
But hold on. Governments are incompetent enough to put asphalt here on earth, but on the moon

[marble hearth]

Pretty sure the millions of years of sunshine have bleached it to a point that it doesn't change much anymore

[low lance]

Yeah which is why it's grey and not black

[marble hearth]

Never said it's black 😭 and the reflectiveness was measured within the last 100 years not billions

But yeah it's not crude oil looking ahh asphalt dark

[fallen obsidian]

It would be to heavy

[summer turret]

its just really hard because you need aperture. most submissions would be done with a 16"+

to be fair the most important thing when imaging that kind of stuff is seeing

you can quite definently image gravitationally lensed galaxies with like an 8" rc if you have seeing good enough and bortle low enough

Ar-III and He-II are more often found in planetary nebulae

[obsidian plover]

never heard of that before

[swift heart]

Doesn't He-II do double duty with sodium? Or is that He-I

Sodium filters might actually be useful now that sodium discharge lamps are dying out

[cerulean elm]

Because wide field and f2?💀

[marble hearth]

24mm @ f/2.8 my beloved

[cerulean elm]

135mm f2

Ooor as everything in this hobby should be measured. T-2.2

[marble hearth]

T ratio..? What's that a measure of?

[cerulean elm]

Transmittance. Basically how much light actually makes it trough the optical system

[marble hearth]

Oh, isn't that harder to measure tho?

[cerulean elm]

It is. That's why is so uncommon

Although, it's not thaaat crazy complex. You need a source of light with a constant and known brightness, and then you measure the same source of light after it passes trough the optics. That gives you the true transmittance.

[cold moon]

Unless I'm insane it should be (A/f²)T, where T is the transmissivity of the mirrors/glass. This is not necessarily a physically coherent value but to compare two systems it's ok

A is the aperture in area

[swift heart]

My RC is T/11.6
But that's assuming minimum mirror reflectivity (96% each)

[cerulean elm]

#1326833769495269376 message
what i got a loooong time ago

[swift heart]

Wait what's the discrepancy...

I might be mathing incorrectly

[cerulean elm]

Ok... there might be a bit of discrepency since i didn't account the mirror efficiency. Plus someone pissed me off by saying that half the apperture is blocked by the CO on RC telescopes XD

[cerulean elm]

I don't mind if I take the fall. I'm not the sharpest tool when it comes to math

[brisk copper]

buh

[swift heart]

yeah it's He-I

[swift heart]

So I'm calculating it like this:

• At an aperture of 203.2 mm and focal length of 1624 mm, my RC is f/8 natively
• With 47% central obstruction, that gives 77.91% clear aperture, so without factoring the mirror transmission in, that gives 8 / 0.7791 = 10.27, which is the maximum T/ratio
• With 96% minimum transmission per mirror, and 2 mirrors, there is 0.96^2 transmission, which is 92.16% transmission
• Altogether, the T/ratio is 8 / (0.7791 * (0.96^2)) = 11.14, making the RC about T/11.

Actually I made a mistake somewhere earlier lol

[cerulean elm]

ok... the clear apperture value is the closest value that we got.. I got 78% and you got 77.91%

[swift heart]

f/ratio is still useful though when talking about resolving power relative to the pixel scale, since the central obstruction technically doesn't decrease the resolving power

(i.e. deconvolution can actually completely restore the lost resolution)

Look how much noise there is in the shadows

[ivory mural]

my s25 ultra performs better than my Google pixel 10 pro xl in low light

Try raw mode since thats what you will be using for astro non of that stupid ai stuff

[ivory mural]

my s25 ultra performs better than my Google pixel 10 pro xl in low light

[low lance]

In raw mode?

[ivory mural]

yes that's why i repeated myself

[low lance]

Also that still doesn't mean that they dont have an aburd amount of noise

[ivory mural]

phones aren't the best option for astro correct

they're still capable

this was shot on my Samsung s20+ like 2 years ago in bkrtle 7

[low lance]

Samsung sensors are even worse than canon when it comes to noise the only sensors that are good are from sony which iphones have but even those are still questionable because of the poor lens quality and bad cooling but there is one option thats a xiaomi phone they have great lens quality along with good passive cooling and a sony sensor

[low lance]

Damn b7

[ivory mural]

last time i checked Samsung uses sony sensors

[woeful rose]

Need more integration time

[low lance]

Nope

They make their own

There is a better Abell catalogue...

[lofty jetty]

I want brutal honesty :)

[summer turret]

stellarium

[lofty jetty]

I'm currently looking for ways to upgrade the website and can't think of many, so I'd like advice from this community

[lofty jetty]

But then you have to spend a bit of time looking for objects across the entire sky :/

[summer turret]

I already know the night sky

[lofty jetty]

Much easier when you immediately have all of the best targets right there

[summer turret]

99% of the time I know what I want to image

[lofty jetty]

The website is built for those who don't

[summer turret]

yea thats why I use stellarium

[fallen obsidian]

right now its telescopius, but nightportal has potential

[lofty jetty]

What makes it better? I could try to add those features

[fallen obsidian]

its got an fov simulator and more changeable varaibles

[lofty jetty]

An fov simulator is planned :)

I'll let you know when its added

[undone sinew]

telescopius was gifted to us from the heavens

[cerulean elm]

But 99% of the time you can't image what you want to image because of clouds

[undone sinew]

Hfhfhfjfj

[lofty jetty]

What are the advantages

I made the poll to know what to upgrade and yall aint giving me much advice here 🥀

[undone sinew]

i dont know i forgot

[undone sinew]

Upgrade to a natgeo refractor scope

Both

but if i had to take a preference, its movies

[delicate lance]

You can with the use of Cygnus Astro

M78 is a banger

Good unmodded dslr target too

So cool seing those 2 stars in the blue part? on the subs already

[urban quiver]

You’re doing broadband right ?

I think il give it a go in broadband Tuesday night

[desert obsidian]

so for the first time in a few months it will be clear tomorrow night

BUT

it’s gonna be 30 below

[obsidian plover]

Under 10 times is actually crazy

There's no way it's that cloudy😭

[bronze minnow]

the uk: hold my anticyclonic gloom

no clear skies for 2 months straight

[desert obsidian]

Yes way

[fallen obsidian]

we ball with clear skies in ny somehow

[obsidian plover]

and here i was frustrated about no clear skies in 2-3 weeks

[brisk copper]

JUST IMAGE THROUGH THE CLOUD!!!!!!

[ivory mural]

try 5 months without being able to image

[obsidian plover]

sounds horrible

[bronze minnow]

the humble nimbostratus cloud

[bronze minnow]

no joke September and October maybe like 3 clear nights total (at the end of oct)
why do u think I was so pissed when everyone was showing their a6 fotos lmao

[ivory mural]

i became like 10 times worse at processing

[brisk copper]

ITS CLEAR RIGHT NOW!!!!

[bronze minnow]

not for me it isnt

[brisk copper]

Ha

hA

Ha

its only gunna be clear for like 10 mins

and its still windy asf

[bronze minnow]

for me it's lowk just been cloudy for the past week

had some rain mostly overnight

[brisk copper]

this what im shooting

im praying it goes well

okay, 10% of frames so far are usable

ive only taken 100

and each is 3 seconds long

okay, im imaging through clouds again

[fallen obsidian]

Image m106

[brisk copper]

no

[fallen obsidian]

Why

[brisk copper]

covered by clouds

thick clouds

[fallen obsidian]

Ahh

[brisk copper]

not just the thin ones im imaging through rn

[fallen obsidian]

It’s clear tonight for me but very winds

[cedar dome]

The humble cirrus cloud:

[obsidian plover]

10mins lrgb 15-20mins narrowband

[proud quarry]

3 hours Lum

[woeful ivy]

15s

[ivory mural]

60-180s

or 15s

depends what equipment im using

[rain void]

f/37?

10 min lrgb is wild

[fallen obsidian]

10-45 seconds

[obsidian plover]

F4.9

Is that not normal ?

[bronze minnow]

cloud100.percent

[rain void]

idk but i'm pretty sure my rig would clip every single pixel lol

b6.5 + f/2 i guess ¯_(ツ)_/¯

[brisk copper]

😭

unlucky asf

browi, would a 1000mp ir mosaic be fire

[rain void]

yeah b6.5 is pretty bad but f/2.2 helps a lot. I also mostly do narrowband for that reason

[brisk copper]

what bandpass do u use, 3nm?

[rain void]

6nm preshifted. 3nm is too narrow to be able to use it with f/2

[brisk copper]

ohh yeaa i forgor about that silly issue

[undone sinew]

Anything over 500ms for me causes star trailing

[woeful ivy]

true

but zoom out

its fine

[marble hearth]

Guiding is a must for harmonics

[fallen obsidian]

what camera should I get thats under 150usd

I olny need a camera

[marble hearth]

Got an oag already?

[fallen obsidian]

no, but I have a 60mm guide scope

oag will be after cc

[marble hearth]

Good enough

1. Check 2nd hand markets
2. Touptek has a few sub 150usd options

Otherwise chdkc out svbony

[delicate lance]

blurx correct only gets rid of basically all coma in that fov already

(not always)

[marble hearth]

150usd is so doable for a guidecam

[fallen obsidian]

im looking at some planetary cams like asi 178 and 224, could I use those

[delicate lance]

yes and no

youd need a 1.25'' nosepiece nontheless but focus is that issue

if you have a guidescope that has a relatively broad focussing range then theres no issue

[marble hearth]

Think u can use any camera as guidecam, the 178 has smaller pixel sizes so might be more ideal

Also zwo 🥀 touptek also offers cameras with those sensors

[fallen obsidian]

its just what im seeing on cloudy nights

[fallen obsidian]

mines like that so

[delicate lance]

zwo is zwo but their cameras are by no means bad

if you find a good deal then congrats

[marble hearth]

Not saying they're bad, just overpriced for what you get

[delicate lance]

take it

yeah for sure

[marble hearth]

Absolutely, especially used

[delicate lance]

but if its used and therefore priced reasonably

go ahead

company loyalty is a lot of bull anyway

id buy a zwo cam if i would find a proper deal lol

[delicate lance]

then yes you can indeed do that

[marble hearth]

Ofc ofc, thought he was buying them new so I suggested a better alternative for new purchases lol

[delicate lance]

the imx178 has gone thru quite a journey

cooled DSO cam to planetary to guide

[delicate lance]

ah got it

[fallen obsidian]

should i avoid the 120mm

[delicate lance]

i mean it is

old

unc camera

but its still functional and it will do its purpose

just not very future proof because its so old

[low lance]

You can use short subs to replace guiding but nothing you can do will get rid of your coma other than stopping your telescope to like f8 and or using a coma corrector both of which require additional money while using shorter subs is free

[fallen obsidian]

but theres also drift correction

[low lance]

You can do that manually

[fallen obsidian]

no nina

[tiny lintel]

get a real mount instead of a strainwave

applies to all strainwave mounts

[fallen obsidian]

https://tenor.com/view/btweers-gif-12554037691025205909

[summer turret]

are you high

[late summit]

he is from the balkans, he's just full of being-against-new-things-that-happen-to-be-good

[cedar dome]

I’m curious on your reasoning

[brisk copper]

le fishe au lava

[cedar dome]

The what

Oh.

[brisk copper]

[bronze minnow]

lava fishen or something idk

[fallen obsidian]

strain wave is the future

[summer turret]

belt driven mounts dont exist?

🥀

[fallen obsidian]

same category

[late summit]

I'm more for convenience than getting a slightly lower guiding number when things are already acceptable, so the choice is obvious

[fallen obsidian]

and better price

[summer turret]

but belts have better unguided performance

[late summit]

don't care, i'm not unguided

therefor that fact will never matter to me

[fallen obsidian]

harmonics are way better for their cost and you can guide them so it dont matter

[cerulean elm]

Direct Drive

[fallen obsidian]

not an option

https://www.ioptron.com/product-p/3372.htm

[cerulean elm]

Get a mono camera😭

[fallen obsidian]

what are the benifits

also this cam acts like mono in nir

[delicate lance]

Way higher sensitivity

Your goal is to get the most sensitive camera which is a mono one

[low lance]

Yeah bro let me just spend 5k dollars on a mount that weights 50kg and can only carry a 10kg telescope instead of spending 2k on a mount that weights 5kg and can carry a 20kg telescope and with zero backlash

[low lance]

Zero backlash zero periodic error it's just

[low lance]

My mount begs to differ

[summer turret]

Sucks to be you

I can pull 10min subs unguided

With a PA error of 8arcmins

[low lance]

Indeed

[cerulean elm]

At what pixelscale?

[low lance]

I was just about to ask that

Lol

[summer turret]

250mm, 4.29um

[cerulean elm]

Let's talk again when you get sub arcsec pixelscale😂
At that scale I can run the WAVE150i unguided and the 2" PE wouldn't even be noticed

[summer turret]

Nor with my laptop to calculate it

[cerulean elm]

Ypu are at 3.5 arcsec/px

[summer turret]

Yipee

[silver holly]

There aren’t any observatory class harmonic mounts.

Therefore I pick worm.

And a good worm mount will guide better than a harmonic

[tiny lintel]

because observatory class and strainwave dont go together
all the "benefits" of strainwave are not needed when you have an observatory

[silver holly]

Yep exactly

[cerulean elm]

Where are the anchors ⚓️?

[tiny lintel]

made of tungsten

[cerulean elm]

Light. I would go with lead

[low lance]

Observatories dont use neither worm or strain wave they use the far superior direct driver

[low lance]

Light I would go with osmium

[tiny lintel]

only if you have $$$
and no not all observatories use DD

[low lance]

Professional ones do

Amateur ones not so much but then again in the Amateur range even a seestar is considered an observatory

Also i have no idea why yall even need less than 0.5 arcsecond guiding i know for a fact most of you have an 8 inch reflector or a small refractor and non of you have consistent sub 0.7 seeing

[tiny lintel]

ahhahah

[tiny lintel]

error: unspecified question

[woeful ivy]

whos don

why are you buying them

[silver holly]

I was talking amateur observatories.

[brisk copper]

what that?

[low lance]

Direct drive?

Basically your entire RA and DEC axis are a giant motor

Well it doesn't have to be

But its the most common form

[tiny lintel]

its definitely not most common

[low lance]

It very much is

Bro has never seen a direct drive mount like what else is it supposed to be

There is no gears involved so the entire axis has to be the motor

By which i mean it has coil windings and looks like this

[silver holly]

No PE, no backlash, perfect “guiding” and huge payloads.

[brisk copper]

soo, i should buy one!

[silver holly]

Yeah they are pretty awesome

The L350 is actually somewhat affordable too.

[low lance]

I mean unless you live ontop of mount mauna kea you dont really need the perfect guiding but the high payload capacity is nice tho

[silver holly]

Most of the time you buy these to go remote.

[summer turret]

They're electromagnetic

[silver holly]

No they are magic

All mounts are electromagnetic

[low lance]

Yeah but even the best amateur location aka chile only has like 0.7-1 arcsecond seeing

[brisk copper]

wait until i make a deisel engine mount

[low lance]

Even shity mounts like mine can do that

[brisk copper]

liek a v8 engine

(idk if theres any deisel v8's)

[silver holly]

Yeah but if you are guiding over a pixel it doesn’t matter.

[low lance]

What

[silver holly]

Bad seeing doesn’t hide bad guiding.

Stars will still be elongated.

Direct drive mounts track and guide below the seeing level in most cases.

[low lance]

Well depends on how bad your guiding is for example in worm drive its large oscillations which cause elongation while strain wave has small but rapid oscillations which cause fuzzyness

Well actually ignore the mount types i mention since they both suffer from large and small oscillations

[silver holly]

Any peaks over your pixel scale will elongate stars.

[low lance]

Well my stars elongate even tho i was still sub pixel guiding so it really depends

[silver holly]

A vast majority of professional or semi professional scopes are well below 1” per pixel.

[silver holly]

Yes I didn’t want to get that technical lol

Technically any movement at all elongates stars.

Unless you are really undersampled.

[low lance]

Personally i think that a simple good quality strain wave mount is enough for most peoples atmospheric conditions and setup and is probably good up to 10 inches maybe even 12 but it needs to have absolutely encorders

[tiny lintel]

@low lance I am very well aware of DD mounts, but unlike your statement most professional observatories are still using non DD mounts.
Sure the new ones use what is the latest, but I encourage you to go to Kitt Peak and see what is used there..

[cerulean elm]

On that I kinda have to that.
Most observatories are going off the idea that if it ain't broke don't fix.
You can probably agree that they might have some mounts that are probably made during the '90s or earlier😂

[tiny lintel]

90s is quite new for some...

[cerulean elm]

I tried to be generous 😂

[low lance]

Tbh i should really start following that

[autumn nacelle]

Alright

Give me a few hours

[delicate lance]

at least put an ASA telescope on it like a real man

[ivory mural]

ive never worn fluffy sock

[brisk copper]

🚮

[woeful ivy]

where grippy one

i can walk easier

[brisk copper]

mental asylum grippy socks dont count

[woeful ivy]

[late summit]

what do we consider fluffy socks?

do winter socks count as fluffy socks?

they're not fluffy per se but they are thick

[brisk copper]

no

by fluffy socks i mean ones that are fluffy

like propper fluf

[late summit]

i don't think i've ever worn fluffy socks then

[brisk copper]

[late summit]

winter socks for home use are peak though

[brisk copper]

i just wear fluffy socks everywhere

[urban quiver]

People wear winter socks? Weird

Just wear regular socks

[summer turret]

Fluffy socks in winter

[late summit]

then my feet get cold during the winter

[brisk copper]

no, they are so uncomfortable

i hate it so much

[late summit]

don't get me wrong it's still regular socks when outside duh

but at home? winter socks rock

[urban quiver]

Slip and fall socks

[late summit]

how do you fall with winter socks

my floor is made out of some type of stone that i forgot the name of in english and even then I never slip

[urban quiver]

mine is wood very smooth

[brisk copper]

stone stone made of stone from stone :D

[late summit]

is it real wood or those wallpaper esk type of floor covers

the latter i understand being slippery

[brisk copper]

my floor only slippy in conservatory and kitchen

[urban quiver]

yea it’s wood but laminated

I think that’s the word

[late summit]

yeah it is

i wouldnt wear winter socks in that either

[urban quiver]

I meant word

[late summit]

i got what you meant

[urban quiver]

I could sometimes slide with regular socks like 4 feet

[late summit]

my bedroom has real wood flooring and i guess it can be slippery when it's very humid

but that's about it

i have carpet covering part of my floor though so

[urban quiver]

Most of my flooring is carpet

Except bathroom, laundry, and kitchen / dining

[delicate lance]

nah they need to be slippy

so you can slide through your house

https://tenor.com/view/maki-jjk-jjk-meme-jjk-memes-jjk-season-3-gif-3959390916293457976

its almost all wood for me, good for sliding, just gotta watchout for gaps in the wood

[undone sinew]

uhhhhhhh i need to make a new poll i ran out of ideas

I got just one more in me

excuse my protostarness if i forgot some important one

[marble hearth]

Waiting for clear skies

[cerulean elm]

Imaging opportunity

[silver holly]

Depends what scope I’m running

[tiny lintel]

kinda stupid poll

[tiny lintel]

its like 500€ vs 2000€

[delicate lance]

oh i meant ignoring price

[woeful ivy]

i pick expensive one
sell it for cheap
buy cheap one multiple times

idk

[fallen obsidian]

[brisk copper]

ya

[ivory mural]

My cc cannot handle full frame

[marble hearth]

Deleting the sun would also delete the atmosphere

[woeful ivy]

cos it gonna snow nitrogen?

[marble hearth]

Yep

[swift heart]

Obviously delete the atmosphere:

• No sun = no planetary astronomy
• No sun = no solar astronomy
• No atmosphere = amateur coronagraphs become viable immediately
• With an atmosphere you still can get seeing issues and UV gets absorbed

[fallen obsidian]

delete rotation

dobs would become meta

its the weirdest thing it dithers really well on its own

[brisk copper]

thats stooopid

tell it to stop

no its working really well

[delicate lance]

it will hurt my pocket

200 EUR worth of filters

[brisk copper]

its the ony way :3c

[delicate lance]

dead chat

[cerulean elm]

Good

[brisk copper]

[mint talon]

7 inchers in shambles

[brisk copper]

yup

i hate 7"

its like 6" and 8" but pointless

worst of both worlds

a 6 incher is perfect for regular use and some travel

while 8 inches and above i would probably keep home

4 inches is best for travel

2,3 and 5 inches i dont care much for

in mai hones opnion

[mint talon]

you can relatively easily move a 10 inch

[brisk copper]

nuh uh

i cant really move a 10 incher i dont think

i can probably use a 10 incher just fine tho

[brisk copper]

also, answer!!!

[fallen obsidian]

like apeture?

[brisk copper]

well yea

[cold moon]

Telescopes?

[brisk copper]

ya

[cold moon]

Ah, then I chose the wrong option

[brisk copper]

wat

wat els coud ut be??

[ivory mural]

1.1" isnt an option

i cant really use my 6" in winter

forced to use the small one

[fallen obsidian]

why

[ivory mural]

nowhere to put it, cold, and extremely uncertain conditions

[lofty jetty]

is there a micro size 🙏

[restive fiber]

I said without corrective optics!

[lofty jetty]

Why make it illegal 😭

[restive fiber]

Poor quality optics without correction

[lofty jetty]

If people want to buy it, let them buy it

No reason for the government to get involved

We almost have too many laws as it is

[low lance]

Id say we dont have enough regulations

Its not the government fault the companies want to run the world into flames just to have 1 extra cent in the bank accounts

And the people are too stupid to see thru their bs so government have to step in

[lofty jetty]

I think people should be able to sell what they want as long as it isn't dangerous

[lofty jetty]

Depends which regulation though

[low lance]

Thats what regulations are for to prevent people from selling scams and dangerous products

[mint talon]

iirc they do include corrective optics, a barlow lens

[low lance]

Not enough

They mean proper spherical corrective optics

Like those in SCTs (they use spherical mirrors and that front glass isn't for show it actually is a corrector plate in case someone reading this doesn't know)

[woeful ivy]

do they advertise it well tho

i bet some doesnt explicitly tell its spherical

[woeful ivy]

if so that should be illegal

[delicate lance]

bro they cant smell that it would be shit

zoomion has an F/4 8'' scope with a spherical primray

[brisk copper]

[delicate lance]

it literally cant focus

[cold moon]

I'm not sure how "yes" is winning...
