@warm perch Here it is with NoiseX

warm perch Jun 30, 2023, 9:16 PM

#

can you send as a tif please?

fresh herald Jun 30, 2023, 9:17 PM

#

yeah. i think one of the problems you're having is the red saturation though. that big cloud of red on the lower left is actually supposed to be dark dust.

warm perch Jun 30, 2023, 9:18 PM

#

really? i mean it is the cygnus wall?

#

here is the stacked if you wanna have a shot

fresh herald Jun 30, 2023, 9:20 PM

#

i will have to link to the tif, i can't send it here

warm perch Jun 30, 2023, 9:20 PM

#

fresh herald Jun 30, 2023, 9:21 PM

#

oh. ya thats it

fresh herald Jun 30, 2023, 9:23 PM

#

i'll play around with the cygnus wall now 🙂

warm perch Jun 30, 2023, 9:23 PM

#

please do 👍

#

its only like 2.5 hours but i think the reason its so noisy is because i was underexposed since i did iso 800 at f6.3 200s

fresh herald Jun 30, 2023, 9:24 PM

#

i have a very similar image of that area with the same short integration

warm perch Jun 30, 2023, 9:25 PM

#

at that slow f ratio?

fresh herald Jun 30, 2023, 9:25 PM

#

yeah, this is f/7

fresh herald Jun 30, 2023, 9:26 PM

#

warm perch Jun 30, 2023, 9:26 PM

#

fresh herald Jun 30, 2023, 9:26 PM

#

#

asi183mc pro through an at115edt

warm perch Jun 30, 2023, 9:27 PM

#

ok.

#

i hope you can make some sense of that data i have

fresh herald Jun 30, 2023, 9:32 PM

#

it looked very close to what i had there. but less saturation, when i checked it with auto stretch

warm perch Jun 30, 2023, 9:32 PM

#

ok

#

i was using pixinsight but i really dont know how to use it correctly although i have gotten an impressive image by following a tutorial but that did not apply to that apparently

fresh herald Jun 30, 2023, 9:37 PM

#

this data has a very unusual histogram

warm perch Jun 30, 2023, 9:38 PM

#

i can send the lights, darks, flats and biases if you wanna try stacking

fresh herald Jun 30, 2023, 9:40 PM

#

#

i don't think it's that. i've had similar wierdness with my dslr

warm perch Jun 30, 2023, 9:41 PM

#

hmmm. so whats the issue?

fresh herald Jun 30, 2023, 9:43 PM

#

i've no idea. i knew nothing about photography before going into this hobby 😂

#

before i ran noiseX on it, the histogram had that big spike and two smaller spikes

warm perch Jun 30, 2023, 9:43 PM

#

weird

fresh herald Jun 30, 2023, 9:43 PM

#

i've had the two smaller spikes, sort of like an M before from my dslr

#

but never that huge spike
