[copper sparrow]

not on mine

[dreamy badger]

There are polarscopes with levels which is handy

[copper sparrow]

Must be a thing in premium mounts

[dreamy badger]

Then it rotates with RA

[copper sparrow]

I have the gti, I don’t think it rotates with the RA

[frosty coyote]

I've never had problems with TPPA. As long is you run it a few times, it is very accurate. I can easily get 120s subs unguided at 450mm fl.

[copper sparrow]

I don’t even bother running it multiple times and it’s still fine at 490 lol

[frosty coyote]

if you have a large initial error then you need to rerun it a couple times for it to be accurate

[dreamy badger]

You are discovering how much pa error you can get away with without a problem

It's probably less than the RA periodic error you actually have to worry about

[golden spoke]

Wuh oh it seems the 'conspiracy theories and how to avoid them' meeting took a turn lol

[stuck lily]

r/ap sucks

there's so many rude people and bad advice

[eternal topaz]

Who said that?

From reading the convo, this is something you should try out on your own. Drift allignment vs tppa

[frosty coyote]

the issue is not drift alignment vs tppa. It's polar scope vs tppa

[eternal topaz]

They're referring to drift allignment from which you use the polar scope

[frosty coyote]

No, all they said was that they "verified" (by using drift alignment) that the polar scope was more accurate than tppa

ik drift is better than tppa

the issue is polar scope vs tppa

[dreamy badger]

its more complicated than that, basically the idea is that polarscopes largely has one source of error (alignment) when aligned means you can get fairly accurate PAs, and that TPPA is generally not as accurate as other methods since its indirect and susceptible to other uncontrollable errors

the only counterargument i've heard is "its visual so its bad"

[dreamy badger]

and since its common to nail down PA using drift alignment people get an idea of how accurate these methods are

[agile cloak]

Getting advice from r/ap.. not that bad but cmon

[agile cloak]

…

[agile cloak]

Real based

[eager gulch]

lol

[jagged igloo]

I will just wait.

[earnest quarry]

Dubai is the second mascot of this server

You can't

[wispy folio]

excuse me

[earnest quarry]

Bob is the first

[wispy folio]

holy what has general chat done to you

[earnest quarry]

I think you mean what I've done to general chat

[wispy folio]

i legit have no clue who u are icl#

[earnest quarry]

Me neither tbh

I dont know who I am

[agile cloak]

Whoever prays upon my downfall prays upon the downfall of this server

[eager gulch]

why lol?

[eager gulch]

?

[agile cloak]

Because I am dubaiastro the great

They fear me

[eager gulch]

you put an 8" on an eq2, YOU are the one that needs to be banned🥀

[agile cloak]

[golden spoke]

No astrobuiscuit without dubaiastro

[eternal topaz]

bring back dubaiastrology

[indigo cape]

Nick has a point...

[jagged igloo]

It is when a company makes a worse product to get more money

[vestal bramble]

I agree with rude but you gotta give it to them that they are knowledgeable, i just wish it was more welcoming to newer people

[agile cloak]

Well yeah, but sometimes they are also very rough with beginner gear

Which proves ur point yea

[vestal bramble]

Yup

You cant expect a beginner to hypertune their gti lol

[agile cloak]

Exactly lmao

[eternal topaz]

thats cute

[jagged igloo]

@velvet shore it seems your brain is dead because you answered no.

[velvet shore]

Did not.

[jagged igloo]

No I meant the other poll that I made

[jagged igloo]

This one

[velvet shore]

I genuinely had no clue what that poll is talking about.

[magic nexus]

note that split is exaggerating, ill prob end up just getting some elongation

[stuck lily]

I've never heard of any🔥

[opaque depot]

Skill issue.

[solid egret]

probably any bw one

[opaque depot]

Not all black-and-white film stocks are great for long time-exposures.

[solid egret]

ye but

lum

[opaque depot]

My understanding is that in colour films, light sensitivity is not affected in the same way as in the Bayer matrix in digital cameras since the photons are not blocked by the individual colour-sensitive layers.

So black-and-white stocks are thus not inherently more sensitive.

[solid egret]

Crazy

Just look at whichever has the highest qe for the lowest iso

[opaque depot]

It is more useful to look at the reciprocity characteristics of each film since reciprocity failure (light-sensitivity decreasing during a time-exposure) affects some film stocks less than others.

[magic nexus]

fomapan 100

cause its the cheapest film that exists

[opaque depot]

Not a valid reason.

[magic nexus]

then aerochrome cause infrared

[opaque depot]

No.

[opaque depot]

This would be like saying that Astromasters are the best telescopes because they are the cheapest.

[magic nexus]

if you had to buy another telescope after every picture, they probably would be

[opaque depot]

A single roll lasts for quite a while though.

[velvet shore]

I’m disappointed in most of you.

[desert cobalt]

Any digital camera

[winged void]

I'm currently rocking the canon eos 750d and I enjoy the wider view so maybe keep that in mind (Im at 600mm)

you can ofc add suggestions

[wispy folio]

600 mm with th 585 is very limiting

get the 533mono imo

[winged void]

yea the smaller fovs are quite intimidating

[copper sparrow]

Save up for the 533 imo

Buy once cry once 🙂

you're already pretty close

[modest sage]

Yup 533 is double the fov for not double the price.

585 is good if you plan on IR imaging.

[velvet shore]

If you like the wider fov don’t get a 585.

[eternal topaz]

Artemis is 294mc so avoid

[exotic gyro]

why though

[eternal topaz]

294 is notorious for having issues.
For more info ask @strong merlin

[exotic gyro]

I might get the ares because its cheaper, and I could probably deal with the fov when I build my eq plate

[strong merlin]

Might be worth saving the pennies for a 571

Of course not to say the 533 is a bad sensor, it’s very good. Just narrow

I’d definitely avoid the 294 for a first DSO camera

[exotic gyro]

Once I get the eq plate, I won’t need such a large sensor, and I can do shorter exposures with less noise+ some lucky imaging, so I might just go with the 585 or the 533

[strong merlin]

Why wouldn’t you benefit from a larger sensor?

[exotic gyro]

What do you mean, I’m just getting a smaller sensor bacause it is applicable for my situation for a lower cost

[strong merlin]

Oh I mean yea that’s fair

But just remember buy once cry once is real in this hobby lol

[exotic gyro]

lol, also it’s useful for planetary

[strong merlin]

Is it an IMX 585 or IMX 533?

[exotic gyro]

Havent fully decided

Prob 533

[strong merlin]

A 533 won’t be that good for planetary

Low fps

585 is great for planetary, does very well in DSO, but is half the size of a 533

[exotic gyro]

I don’t mind the low fps too much, planetary is something I do rarely, and I want to invest more in dso, only thing that could be an issue would be low fps when lucky imaging, but my exposures will be long enough that it won’t matter

[agile cloak]

@eager gulch got some really dope planetary pics with it

[strong merlin]

585 is the best of both worlds. it does a great job in DSO and Planetary

[agile cloak]

[scarlet mica]

Really? Good to know

[dreamy badger]

533 will be fine for planetary you just need to crop ROI

its not going to be as blistering fast as a 585 but its unlikely you will need that since it can go 100+ fps

[copper sparrow]

Will the 533 be better then my SVBONY sv305 pro planetary cam (290 sensor)

for planetary

[dreamy badger]

No

[copper sparrow]

Because the smaller sensor size of the 290? Or any other reason

[dreamy badger]

533mc has more read noise, not that much more QE, and has lower fps

[eternal topaz]

does the 290 have amp glow?

[dreamy badger]

the 290 gets ugly with long exposures

[agile cloak]

Also 290 has smaller pixels

[dreamy badger]

Not really important with barlows

[opaque depot]

Canon EOS 500.

[winged void]

I coukd also get the ares c pro or the asi533 c then. Would be in the budget

[quiet pilot]

533mm

[opaque depot]

No.

[winged void]

or I give a f about astro and get a good lens or a sony

[quiet pilot]

that would be terrible

[opaque depot]

Horrible idea.

[opaque depot]

Why is Ektachrome so popular?

[agile cloak]

True

Still good tho

[eternal topaz]

I'm very curious to know what people prefer

[golden spoke]

Minecraft or interstellar (could be bias as ive not watched star wars that much)

C418 hits a note in my heart

[frosty coyote]

C418 the goat

[jagged igloo]

80 minutes left.

[copper sparrow]

Most challenging poll ever

[frosty coyote]

not really. Minecraft built our childhoods one block at a time

[earnest quarry]

Why must you do this

All of them are awesome

I listen to interstellar a lot more but minecraft is

And star wars as well (but I'm going to have to put them last)

I'm going minecraft because I feel the music is a bit better to listen to by itself

[earnest quarry]

Note: by minecraft I mean c418

[spiral parcel]

shit

misread 😭

[opaque depot]

Who dared to ping me?

[earnest quarry]

@brazen sundial erdo is from hungary isn't he? sarah is african

[brazen sundial]

Oh shoot

Deleted it cos it wouldn’t let me edit it but now can’t be arsed to make a new one

Anyway

I think Aveline would be a good candidate

Oh god

I mean, many of them are pretty much synonymous with him

[earnest quarry]

oh hell no please

i'm catholic and couldn't imagine what the church would be like under him

[slate smelt]

sigh Please keep it on topic in the astrophotography forum. Thank you.
