this is the best i could get

[heavy turret]

i need to have acess to it

[delicate anvil]

im new to google Drive, is it locked to the public?

https://drive.google.com/file/d/1N3QakefRL4Ds4wJR2DGmpWVjM3sdBtgJ/view?usp=drive_link

[heavy turret]

yes,

[delicate anvil]

I'll fix it

[heavy turret]

you need to click at where you cpy the link and put it in "everyone that has the link" it's like public when you do this

and them you send us the link again

[heavy turret]

only a question is it tracked?

[delicate anvil]

nope

I'll resend the link

https://drive.google.com/file/d/1N3QakefRL4Ds4wJR2DGmpWVjM3sdBtgJ/view?usp=drive_link

[heavy turret]

nice one for an untracked

[delicate anvil]

Thank you

[heavy turret]

now i got it

[delicate anvil]

It's bortle 2 so that might make a difference

we live in a rural area so that's a blessing

[heavy turret]

hahaha i would love to

if you want here is an data i took of the galactic center at bortle 9

untracked too

[delicate anvil]

I'll take a look, i requested access

Bortle 9 :(

[heavy turret]

ok

[heavy turret]

its actualy realy good i took with an r7 canon

[delicate anvil]

I'm sure it's good I just feel bad for you lol

[heavy turret]

yeah haha

i live in Vila Velha/ Brazil city

you now have access to it

[delicate anvil]

Ty

[heavy turret]

i would recommend you to get less exposures at your photos, you got some small star trails

and some bad commet shaped stars

[delicate anvil]

I'm actually trying to figure that out rn

[heavy turret]

so i also recommend you getting your obturator to like 8

[delicate anvil]

Whats that

[heavy turret]

wait a sec

[delicate anvil]

Also if its clear tonight i'll shoot at f2.8 instead of f2

[heavy turret]

i think it need to be more

[delicate anvil]

Wdym

[heavy turret]

the F is the obturator. try to gt f8.0 exposure 4 secs and iso 2600

how bigger is your f the more corect are the stars

[delicate anvil]

Isnt f8 too closed?

[heavy turret]

it is but if you want better stars its the only way i know, so you would need more data

[delicate anvil]

I'll try closing the aperture until the cones go away

[heavy turret]

also i recommend more zoom if possible

what focal lenght and pixel size?

[delicate anvil]

A 135mm lens is arriving tomorrow and I get the m42-nikon f adapter in the mail in a few days

[heavy turret]

thats good

[delicate anvil]

50mm, 4.2um

Also just curious, why does pixel size matter? I see many people talking about it

[heavy turret]

how smaller it is more detail you get because if its smaller so there is more to cover the sensor and this means that you can get details that where smaller than your last pixel: the bigger one

[delicate anvil]

Oh ok, ty

[heavy turret]

here is my try

[delicate anvil]

wow that's nice

how did you do it? what tools

[heavy turret]

thanks

[heavy turret]

i only used siriL

[delicate anvil]

well what tools in siril?

[heavy turret]

i first use autostretch to see with what i am talking about

them i cut around the nebula or the galaxy getting some space in the photo without galaxy only stars

then i use background extraction to get out the weird collors at the background

after i use photometric collor calibration and green noise remover

[delicate anvil]

Oh ok, ty

[heavy turret]

them i get generalised hyperbolic stretch transformations and histogram

and its finished
