Anybody here have some experience with star photography?
How dark does the sky have to be to get some decent results?
Sucks that most of the civilized world is so shit at handling light pollution, but I'd like to give it a shot.
I live just 25 min out of the city, but it makes a huge difference.
How far out you have to travel depends on the size of your city, really... just drive until you see a lot of stars. Head away from the next closest city.
I'm no expert, but here are two shots from different locations.
I don't remember if processing might be a bit different, but both were shot at same settings.

Alright, that's pretty good. I might be able to get some shots not too far away from home. Mt. Fuji is yellow on the dark site map.

i've recently started taking some film shots of stars but havent developed them yet.
i live in center yellow circle on this and can see the milky way fine from my house, though i'd say its noticeably brighter just a couple miles west in the dark yellow/light green areas. the light from the red metro area is very visible on the southeast horizon.
never bothered to go out to the dark green/blue areas just to look at the sky, but i wanna do it sometime.

In heavy light pollution you''ll want to expose to the right (ETTR), you want to overexpose the image so all your information is to the right of the histogram. Just be sure not to clip any information
>>2992237
You can cut a lot of light pollution with a optolong UHC filter, if you order via taobao you can get up to 82mm in size.
I live in rural Japan in the mountains with only an onsen and hotel, no shops, houses etc and its still not that dark on dark site finder, most of Japan no matter how isolated you go seems to be like that on the site, not sure why, even though theres not much lights here and its elevated high.
I figured my sky brightness with my camera with this method after I took the image and tried to find a scale to compare the EV too.

Mines about EV -7.5 when exposing the night sky to middle grey.
I was able to image Orions Nebula (M42) without much issue using camera lens and mini tracker.
My UHC should arrive tomorrow.
>>2992312
The Mag/sq arc-sec I had was about 20.4
Orion attempt unfiltered with Super Takumar 200mm f/4
>>2992313
Processed too heavily and kinda messed it up, this was one of the unstacked source images for it after raw conversion and cropped for faster processing.
>>2992314
Shooting out the window with loads of lens reflections
Live in a place with minimal to no pollution, difference is huge and very noticeable when I visit bigger cities.
Why is the center of russia this light polluted?
>>2992313
Was this tracked? What mount did you use?
>>2992352
Sightron nano tracker I got on special in Tokyo, the red coloured one was much cheaper.. guess people didnt like the colour red.
I need to work on good alignment if I want longer times on this tele or longer tele or stick it on a cheap Q7 or something.
The above was A7s + 200mm and cropped.
>>2992352
Since its a close crop in rather than the whole frame, you could likely do it by centering the object in the frame and stacking untracked images with DSS since its cropped anyway, exposure of 1 sec may work with 200mm.
>>2992351
Oil/gas fields?
Hurr durr.
>>2992351
>>2992362
Yes.
>>2992369
Looks like some creepy alien wasteland.
>>2992370
The area is huge, that's just a bit of it. I've just read the pollution there is terrible.
>>2992365
triggered
>>2992372
This could be Paris.
>>2992328
but, anon, night sky isn't actually blue
>>2992407
It is here in Norway, because the sun doesn't completely set during the summer.
>>2992389
Yeah if nobody ever turned their lights at their homes
>>2992552
That sky could maybe be possible if there were no lights point towards the sky.

Which, once again, its impossible basically
>>2992580
If people and the city weren't such degenerates with their lights, then no, not impossible.
>>2992558
and how exactly are you going to shoot astro with heavy cloud cover? You fucking asshat
anybody try to shoot that comet that's supposed to be visible for new years?
supposedly can see it with binoculars or telescope, neither of which i have. tried with 200mm but didnt see anything in the viewfinder, will have to check the negs later :|
>>2992601
Artificial lights affect the night sky even without clouds.
Got my UHC today, looks like clear skies tonight so Ill report back on the effective lp reduction later, already know its pretty effective so should be good if I can balance and correct the images.
>>2992820
Tonight its about EV -8.1 for sky fog to reach middle grey, about 20.7 Mag/sq arc-sec.
Obviously colour balance is way different, but about 3 stops more exposure to reach an equivalent middle grey exposure from what I can tell with the filter.
Thats an improvement to a potential of 22.96 with objects that respond the best (objects that fit mostly entirely within the wavelengths not cut out).
>>2992584
you basically are suggesting that everyone should point their lights down, even cars, even window lights. You are clearly an idiot
>>2992970
Car lights already point down to an extent, and lights from windows aren't meant to illuminate outside the house, so covering up the window works wonders.
You tell me why we need shitty street lights like this.

I did live in a nice dark sky site too at 8000ft. Now I am in a city, and it sucks. Nice by the way.
>>2992979
To give those who are fragile a sense of security is why. But the problem is that it makes for a less secure area. That is because the criminal element can hide in the shadows while you are blinded by the lighting.
Soooo nowhere.
Awesome.
Whats for lunch.

>tfw darkest night is an hour's drive away
Doesn't matter because astro is as pleb tier as it gets anyway.
>take the same photos of the same things from the same perspective as everyone else has since literally the dawn of civilisation
>all that matters is your gear
>>2992361
thanks
>>2993230
>all that matters is your gear
it's the ultimate gearfaggotry
desu though, processing your data is a huge part of creating good images
You know, light pollution can be canceled out a bit by moving onto a mountain / hill.
this picture was taken at the place shown in the next post.

the city sonneberg was only a few hundred meters / up to an kilometer away, but also a few hundred meter below.
