Narrowband and Luminance

Post by Forum_2018 »

Hi All

I have recently made the jump and purchased AA6. So I am at a very early stage of learning about AstroArt. For the last 10 years or so, I have been imaging in narrowband and processing with CCDStack and PhotoShop, with some tweaking in PaintShop Pro.

To get started I thought I would keep imaging with SGP, then process my lights/flats/darks in AA. I have an ATIK 314L+, ASI1600, ASI290, and ASI224 (colour).

My process in CCDStack/PhotoShop was to take my Ha and Oiii and simply do a Bi-colour. Sometimes I would create a synthetic Green. Then I would add the Luminance. All good, and I am happy.

To my question - most of the tutorials I can find seem to focus on RGB. I have seen one video on Bi Colour processing, but it did not include anything about Luminance. So I did a Bi Colour and created a file. Then I loaded that file along with my LUM. [Opened TOOLS/Preprocessing, then my two FITs. In OPTIONS, AutoAligned]. It worked.

I am wondering if this would be the workflow for Ha, Oiii, LUM, or is there some other way to do this?

Thanks
Darrell

Hello Darrell,

There are tutorials by Vicent Peris on PixInsight (in the Tutorials section). Perhaps, they could be helpful.
