@neat parrot your process is incredibly beautiful
who’s?
The guys that captured this data
i think its a little bit better
this is my attempt
Lovely data! fantastic detail!
WeBo 1 just in the frame is a nice addition
What equipment are you running? @neat parrot
This looks amazing
i used a zwo 183 mc pro and a zenithstar 61 with an L-extreme filter
how did u get such nice details
Not even gonna lie... I didnt even notice it
Careful stretch, careful and light unsharp mask in PS along with noiseX to clean up things.
It's such a neat Planetary nebula
Prolly one of my fav
also @minor sierra how did you get the stars to look like that
i always struggle with the stars
Used gaussian blur in an iterative manner to get a gradual star glow. I duplicate the star layer - blur it by 2px - use curves and clip blacks to remove the blur from dimmer stars - then blur by 2px again to remove the harsh transition caused by crushing the blacks - then duplicate the blurred layer and do another gaussian pass of 3px - then keep duplicating the 2px blur layer and each time increase the blur by 1-2px. I usually do it until I get to 35px as this creates a nice gradual glow with natural fall off.
And of course you can flatten all the blurred layers and then apply Saturation to get even more star color.
i dont exactly understand the prcoess, is there a video or something to it?
I haven't seen anyone do it exactly the same so I don't know if any vids on it. I am going to make a tutorial on it but it likely will be a while.
did someone say webo-1?
Still trying to get my stars to look that good…
Any Help?
Dam I forgot about making a tutorial for that, been focusing on some other content.
It's a process that's best explained visually, I'll get a video out on that today actually since I have time atm.
If I don't then remind me lmao, that's one of the main things I want to get done.
I have new data to process and will likely use it for the video
alright bro appreciate it
after 1.5 years of bad weather still can’t get my head around how good it looks
did you get the video?
Getting the data prepared now actually. I might be able to get the video uploaded tn hopefully.
Making sure this data isn't gonna be ass 
dont hurry cuz of me
Have you gotten around to it?
Finally got it uploaded
This was a highly requested tutorial, so I figured why not start off a Photoshop Tutorial series with it!
The same technique can be executed in Gimp or Affinity Photo!
what cam did you use with it
because i think the sensor size of my 183mc is too small and the stars end up looking bloated
Canon XSi / Rebel T5 / ZWO ASI 1600mm pro
And yea the 183 has pretty small pixels and fov
Id def look into a 2600mc pro if you wanna stick with OSC.
its soo expensive :(((
what do you think i can sell a used 183mc pro for?
still in pristine condition id like to believe
i havent really dont any astro in the past year cuz of the horrible weather
soo im kinda hesitant to invest into a new cam
183mc will likely go for 450-500
USD
533mc is a solid upgrade, can be had used for 600 USD.
ikk but the square sensor is proper turn off for me
i feel like i still have too much noise for the time im putting into a target
maybe i have too high expectations but after32 hours of shooting the tulip nebula with an l extreme this is what i get
Your based in UK I presume from what you said about weather 
nahh im swiss
Ahh
Honestly, not bad. That's what id expect for 30hrs.
It's noisy yea, but def what you should expect with that old of an OSC cam.
so a new 2600mc would improve that?
It's the best sensor tech out rn to consumers, so it most def would lmao.
Yea I that's a no go lol
wdym
My 1600mm is already rough to use. The only thing keeping it relevant is because it's monochrome. The OSC version is an older sensor than the 183mc iirc.
oh damn
ok
i used to use an old dslr and the stars were so crisp
thats all i miss since i got my first astro cam
cuz of the sensor size probably
Yup, much larger fov. So stars appear sharper. They're technically the same size, but because you've "zoomed in" closer to the optical limit, the star sizes appear larger.
yeaa
does something similar go for details of DSOs?
like better detail or what not
Yea all optics have a limit of what they can resolve. So if your camera's pixel size gets small enough, it gets to a point where the optics can't keep up. This is called "sampling".
So everything is affected
ahh ok makes sense
Star sizes being the most apparent
how was the transition to mono imaging?
Incredible
I went from a modified Canon DSLR from 2008
To mono so it was a massive upgrade.
I’m considering it, because i’m getting bored the red look
