good luck lmao

[clear oyster]

I can get it

but it will be blurry

green channel

[rain solstice]

No nebula though

I can get the trunks but the nebula will be hard (havent processed it yet)

[clear oyster]

its right there

[rain solstice]

Yes

But no nebula

[clear oyster]

this is the best I could get

[rain solstice]

Yeah

Just very dim sadly

[clear oyster]

the outer nebula is there

its in my image

just ass

[rain solstice]

Yeah

Need to mod my cam and do it on a new moon

[clear oyster]

its not bad though

at least I got the outer nebula to pop out

i tried something different

pick which one u like I guess

[clear oyster]

elephant trunk inst there

isnt*

[rain solstice]

The nebula is

[clear oyster]

it should be right here

[clear oyster]

the main part isnt

[rain solstice]

Its just too faint with a full moon

And unmodded

[clear oyster]

that part

isnt there sadly

[rain solstice]

i need more data to get it

also no dew and no moon

[ashen palm]

Bias frames next time!

[slender mirage]

@rain solstice nobody is stopping you from shooting emission nebulae

but future tip

I wouldn't do them again with a stock dslr

even with a modded camera the elephant's trunk region is not easy

its best as a narrowband target imo

[rain solstice]

I did

[ashen palm]

what iso did you use?

high iso can create a lot of noise also

how long were the exposures

[rain solstice]

1m 400 iso

or maybe 30s

[ashen palm]

400 iso way too low, it does benefit in not making much noise but with that youre not going to get anything

Is this tracked?

[rain solstice]

yeah

i have realised now

on M45 i will do 3-5m subs and iso 400 though

[ashen palm]

you can easily go up to 4-5 min subs if you have a swsa or other

[rain solstice]

I'll ofc try but I'm at 135mm do idk

[ashen palm]

even better, you would have some woble in the mount anyway so with 135 you wouldnt see anything

[rain solstice]

yeah

idk how to dither though, is that a problem?

[ashen palm]

also lower Focal ratio = more light

[ashen palm]

swsa right?

[rain solstice]

yeah im f/5.6

[ashen palm]

with this app i think you can dither

[rain solstice]

i have it

but dont i need to plug it into my camera?

[ashen palm]

you kinda can dither without guiding

[rain solstice]

yes but i mean its asking to put the exposure and stuff in

for that i need to plug in my camera to the swsa

also dont i need my phone outside all the time?

[ashen palm]

no

wifi off on run will fix it

[rain solstice]

so once i press run i can disconnect?

[rain solstice]

thanks, how much shall i dither?

[ashen palm]

that one

[rain solstice]

dithering range in arc min

[rain solstice]

yeah i did it

[ashen palm]

im no expert at that really, i suggest you ask someone else with more knowledge

[rain solstice]

can i ask one last question sorry?

[ashen palm]

ofc

[rain solstice]

if i dither do i need to change anything about processing?

do i stack and edit the same?

[ashen palm]

well dithering just helps to remove the lines

[rain solstice]

yeah walking noise

[ashen palm]

yeah

[rain solstice]

alright thanks

[ashen palm]

but i know siril has this banding reduction too

never used it tho

[clear oyster]

f/5.6 can still get stuff

here is my 55mm lens at just an hour

at full moon as well

[rain solstice]

yes i am aware

i just mean f/5.6 is not too good compared to like the roki with like f/2

[clear oyster]

im doing oeion ronifhr

orion tonight
