Untracked Astrophotography

[lusty mantle]

milky way core, new version

[robust drum]

This is one sub at 1/3 of a second...

[paper arrow]

there are stars

however they are lines so it might struggle to stack

[dark token]

ive seen astrosurface work on stuff like that, worth a try at least

[robust drum]

ill try ty

[robust drum]

yea...you think its caused by the shutterspeed?

[dark token]

trailing is caused by too slow of a shutter speed, but since quickening your shutter speed would get you even less stars im not sure what you could do

[robust drum]

maybe increase my iso …🤔

this immage was shot with iso 1600…

[paper arrow]

Yea that's waay too low

[errant lichen]

77 minutes of orion constellation

Suprisingly horsehead pretty visible, i had 0 expectation about horsehead and flame lmao

[sharp ruin]

With the right equipment, 77 minutes is far more than enough to capture decent details in the Orion Molecular Cloud Complex, including the Orion Nebula itself, plus the Flame & HorseHead region.

Heck, I was able to capture the HorseHead with about 16 minutes of integration time using just my phone and a StarBlast dob.

It doesn't take as much to resolve the HorseHead as many people make it out to be. Now, seeing it visually with no camera aid? That's a different story.

[sharp ruin]

What was your equipment used, btw?

[errant lichen]

We have much, muchh different setup

Your long diameter of your scope which make its kind of easy to capture it, mine was stock camera and cheap lens

[sharp ruin]

A stock camera and a basic lens will do better than a phone would in the long run, to be fair

it's an actual dedicated camera with an ideally sized sensor, vs a phone camera with a tiny sensor

[errant lichen]

I live in b9, need way more integration time

[sharp ruin]

Ah, that definitely does not help

I think that's your biggest limiting factor

I live in a place that fluctuates between B7.5 and B8, and my skies are still useable

[errant lichen]

I saw someone did 3 hours and it has same result as mine

[sharp ruin]

That could be a processing thing too tbf; bad processing can ruin hours of data

or rather, atleast make poor usage of said data

[errant lichen]

Yeah, you had like 6 inch dob?

Thats pretty big tho

[sharp ruin]

4.5 inch

450mm focal length, 114mm aperture.

[errant lichen]

Thats good

A reflector

[sharp ruin]

Yep, dobsonian alt-az mount

[sharp ruin]

Good I suppose, better than most if not all hobby-killer or cheap entry level scopes.

But it's definitely not the best

Fantastic for its size though

[errant lichen]

Poor seeing can make my data looks awful too

[sharp ruin]

Yeah, for sure

[errant lichen]

Yeah maybe that, but i dont really care, clear skies in my place are rare

[errant lichen]

Yeahh, sometimes its not about the device, its about man behind the gun

[sharp ruin]

I wouldn't call myself the most experienced amateur astronomer. I know more than the average beginner, but certainly not a lot.

[errant lichen]

Im not that nerd also, as i attach my camera, i start to take picture

[sharp ruin]

I'm sure I'm also somewhat limited by the usually less than good seeing of the Northeast US, and the bortle 7.5 ~ 8 conditions.

[errant lichen]

Yeah live in high bortle sucks

[sand cipher]

One doubt guys
In untracked ap with dSLR , lens and tripod. Do y'all have timer between every shots ? Like say 2 second exposure? So do y'all have timer between every shots for focus or nah? It's fine

??

[lusty mantle]

and with low light pollution

[lusty mantle]

damn

[lusty mantle]

nope, i do it continually, even if i wanted i wouldn't be able to since i don't have an intervalmeter

[sand cipher]

I mean without any timer, we can time but I don't know if without timer, the focus would be fine

[lusty mantle]

wait, even without the initial timer? or just the timer between each photo?

[sand cipher]

Initial time is necessary but I am talking time between each shots

[lusty mantle]

oh, this one i don't use

[lusty mantle]

omega nebula
9x1 second iso 1600

this could be so much better if i had used a higher iso and if it was made in raw image

and with more dark frames, just 10 is almost nothing

[robust drum]

nice 👍
is there a reason you only took 9x1 sec frames

[lusty mantle]

i took 10

1 sec is what i theoretically can make before the stars start to stretch

only 9 it's because it wasn't my target of the night, just took a few photos for fun

[robust drum]

i see

[lusty mantle]

10 minutes of ngc 6438

[lusty mantle]

remake using graxpert

[errant lichen]

7 minutes lagoon and trifid nebula

[lusty mantle]

carina nebula (100x0.6)

i will make more subs another day (also the flat frames)

[errant lichen]

1 hour untracked lagoon and trifid nebula

[paper arrow]

pretty exxplosive

[paper arrow]

hows the 3hr project of carina going?

[errant lichen]

Im still collecting those pics

[paper arrow]

carina crosses the meridian early

[errant lichen]

I got like 5000k images rn

Heres weather like very rare to clear

[errant lichen]

Yea guess im pretty fricked up

I got like alott alottt of stacks artifact

[paper arrow]

how much int you at now?

[errant lichen]

Still 1 hour plus+

1 hour and 30

Minutes

[paper arrow]

yikes

i would wrap it there

[errant lichen]

I cant get enough clear skies in my city ._.

[errant lichen]

Yeahhh, i think so, ill get more int, ill make it to 2 hours i guess

Ive got like 150gb ++ data

Drained my ssd storage lmao

Hey i wanna ask, i always run into a problem when taaking flats, i use white clothes to diffuse my phone screen light, but when comes into stacking, my flats just... wont work, surely it removes the dust, but it shows like weird black blobness, idk id like to see another way to take flats?

[paper arrow]

can you send me a screenshot of what your issu e is

[errant lichen]

this is my stacked images with flats

after background extraction

this is without

this is my flat

captured the dust but.. idk do you guys see a band in there?

[viral rivet]

clouds?

[viral rivet]

yeah, its definately there

[errant lichen]

nope no clouds

[errant lichen]

could you suggest me how to take flats?

kinda struggling taking flats

[viral rivet]

take a white T-shirt and cover it over your lens, then use a white light (which covers the entire t-shirt uniformly)see the histogram, change the exposure accordingly

[errant lichen]

yea tried that

[errant lichen]

looks like this

[viral rivet]

hmmmm, what equipment u using?

[errant lichen]

like my camera gear?

[viral rivet]

yeah

[errant lichen]

canon 1300d 70-300mm lens

i use 70mm

[viral rivet]

i see

whats your light source?

[errant lichen]

phone screen

i use Av mode to shoot flat

[viral rivet]

does it cover the entire screen?

[errant lichen]

yess

[viral rivet]

is the shirt flat with no curves?

[errant lichen]

i tied it with rubber tho

like twice

[viral rivet]

can you take a pic of the arrangement plz

[errant lichen]

alright wait

[viral rivet]

thx

[lusty mantle]

how are your ssd holding it?

[errant lichen]

dying rn

[errant lichen]

i bought 2 tb ssd

[errant lichen]

Heres my set up

[viral rivet]

Looks good

[errant lichen]

southern pinwheel galaxy

15 minutes exposure

man this target tbh its kinda hard to do it untracked

[paper arrow]

galaxies are stuff i wouldnt reccomend to do untracked

[flint dragon]

Attention thread lurkers, your thread has been selected in the champion of thread comps. Go vote! #1369694419963613295 message

[lusty mantle]

try to find a galaxy closer to a bright star (bright enough to see on the camera screen, or pc screen if you aren't using a dslr) or do what i do and shoot near the celestial pole to make longer subs

[strange seal]

Woah 5 million images is a lot

[lusty mantle]

[errant lichen]

Agree

Need a tracker lmao, my siril wont recognize the stars, so many lights frame wasted

[errant lichen]

I think ill do andromeda, but its still low in this month

[lusty mantle]

same

[tidal tide]

activity in untracked thread

[paper arrow]

[sharp ruin]

you love to see it

[gilded crest]

8" F/6 ZWO 585MC. 100ms to avoid star trails, maybe I can experiment again at 200ms. Gain was like 550? BIN 2X2. 2 min only. Only lights frame. Bortle 4. Firecapture (sorry I'm planetary) and PIPP surface stabilization mode, I've tried planetary mode for comet and it works. What did I miss?

[viral rivet]

Hi

[hallow tapir]

Not bad

Oo

=

[drowsy sundial]

This feels like home

Untracked andromeda, cygnus and orion

omgg I love the effect!!

B1 😭

[tidal tide]

2022 message 🥀

[paper arrow]

weird bell thing lmao

[tidal tide]

juh, its a weird bell thing

[drowsy sundial]

Guys what target should I go for

[night magnet]

What’s your gear

[drowsy sundial]

[sharp ruin]

Hoag's Object

[night magnet]

Double cluster

[drowsy sundial]

What abt nebulas and galaxies?

[night magnet]

How far are you willing to go

[drowsy sundial]

All

[viral rivet]

hi
