andromeda Galaxy (M31)

[sharp kraken]

Hey guys I’m just wondering how people get color from the andromeda Galaxy? After I process my data I get a almost yellowish color, no blues like other photos I seen before

[toxic jacinth]

So looks like you also have some gradients, have you taken any flats?

[sharp kraken]

No 😂

You think flats are the problem of not seen the colors?

[toxic jacinth]

No, but flats help correct for vignetting and other things, like I use my flats for white balance as well

Have you used siril's PMCC tool?

(photometric color calibration)

[sharp kraken]

I never use flats before so kind of new on that

I used pix and photoshop

[toxic jacinth]

Ok, so pix has that too, it's one of the first steps I use for any processing

That one does correct the color properly

[sharp kraken]

Color calibration?

[toxic jacinth]

Photo metric color calibration, yes

You tell it where in the sky you are and it uses survey data to correct your colors

[sharp kraken]

Ohh cool

[toxic jacinth]

Afterwards you may still need to remove some green noise via SCNR though

Also, I'm not a PI user, so won't be able to help you there

[sharp kraken]

I’m trying it right now

@sharp kraken for pix you can also download the needed catalogs (GAIA etc.) locally so you can do the calibration offline as well

[sharp kraken]

Thanks

[misty storm]

it's this stuff on the Software Distribution page

but you don't have to, it also works online

[sharp kraken]

Im new to pix so I have to watch a lot of videos to see what I’m missing

Hey everyone. I captured M31 last night and did some processing today. Anything I could make better if I were to do a re-edit? There is definate Chromatic Aboration due to using a 75-300 kit lens. But tell me what you think - unless this is the wrong place for this message
