Hello. I am completely new in APP. Already done some good picture with it.
I do a night session for Neowise comet, with 27 lights and 30 DOF (of each), with an partially defiltred DLSR. When i get the processed image, the head of Neowise is much more exposed (overexposed) and an artifact (like a grey zone) is present on both side of the head. (The lights doesn't present this artifact).
What is the problem ? Defiltred DLSR, too much lights (i try with different numbers of light, and that change the artifact). Is it possible to reduce the total exposure of the brightest area ?
Thanks for your help
The images : 1 light (i don't understand why it is green, because the raw file is red due to partially defiltred DLSR) and the second picture is the processed image in APP (with the artifact)
This could be because of a combination of overexposure and the way the dslr was modded. But I’m guessing a bit here. If you want you can upload the files to our server to be included for comet registration testing in APP as we want to support that in a later version, tricky data like this will help us get the best overall result for it. You can find more about the upload process in the forum message by Mabula. If you uploaded it, let me know and I can already have a quick look.
Hello Thanks for the answer. If you look the picture of one of de lights, i don't found it's overexposed (also not in the area where it is the artifact. Anyway, if i hear you, it's maybe not a dummies workflow !
Sur i can send you the data, but it's huge. Do you want also the DOF ? Light and DOF is 1.2 Go !
Let me know
Whoops, I totally missed your reply, very sorry about that. If you want you can upload the data to here;
Go to https://upload.astropixelprocessor.com and use upload1 (or upload2 till 5) as username and password will then be the same as the username.
Create a directory named “mcegli-cometoverexposed” and upload in there. Thank you!
And also test the new beta, it will now have comet stacking support.
Hiii
Some month (year later), i try again with the same lights, flats, etc but with the new 1.083 stable.
the problem from the artifact is gone. But hard job.... For the process (because it's not possible yet) for having the stars and the comet sharp (i try a lot of things in APP but i'm really new in APP so i don't found the solution(i also tray the method from Warwick Anderson https://www.astrobin.com/8pzs8i/ but without success)), so i do :
1 integration for the stars
2 integration for the comet with comet method
3 stack in Photoshop the two picture + some cosmetics
Like many, i wait for a complete sharp integration.
@mcegli Could you please attach a JPEG image? That way we don't have to download your TIFF file and open it in an external image viewer. Thanks!
