How to stack RGB images

rodd

Hello all--I am used to Deep space imaging, and imaging planets with Color cameras. I got a Mono and shot RGB avis of Jupiter but now do not know how to combine them. How do you align images that do not have any stars? Pixinsight uses stars to align. Will Registack or AUtostakaard 2 do it?

Thanks.

Planetary/lunar/solar images should be stacked with Autostakkert (planets with the help of Castrator) if you are asking for that. If you want to make RGB out of separate processed frames then you can use Nebulosity, AstraImage or layers in PS or likely in PI.

One can only stack in PI once the images have been aligned--which can only be done using star alignment--there are no stars in planetary images. I want to make a RGB image using a mono camera (ASI 174MM). I have AVIs of R, G, and B. They are individually stacked. How do I combine them into 1 image if there are no stars by which to align them?

I don't use PI, I just use AstraImage or WinJUPOS for it. Those apps don't require stars for that.

So you can stack 3 images (R,G,B) to get a color image in Winjupos?

Yes, but WinJUPOS is planets only and is tricky to use (you don't directly use 3 image files to get color RGB - you get it by 3 image "measurements" with market planet position and orientation).

In order to get color you have to at some point combine the R,G, and B images. All the software I have uses stars to align images. Since doing RGB planetary imaging is VERY POPULAR--I am finding it exceedingly frustrating that finding out how to combine the images is so difficult.

You can use Photoshop RGB tool and manually align R, G and B channels. Resize (not zoom) images to very large scale will let you do precision manual alignmemt, then size it back down.

I don't use Photoshop. I have Pixinsight, Nebulosity, Registack, Autostakaard2, AIP4WIN, and soon Deepskystacker. Can';t deal with a monthly fee. This is a popular thing to do--RGB of planets using mono cameras. Why am I having so much difficulty finding someone who can tell me how to do it without Photoshop. Amazing.

FitsWork http://www.fitswork.de/software/softw_en.phphttp://www.fitswork.de/software/softw_en.php can do it as i remenber. Else look at the "free" software as GIMP https://www.gimp.org/https://www.gimp.org/ or PaintNet http://www.getpaint.net/index.htmlhttp://www.getpaint.net/index.html.

Using myself AstroArt for stacking and merging of R, G and B picts, but the program costs money.

Enjoy Leif.

Does Astroart use stars to align?
