Title: Superluminance with Drizzle
Post by: niccoc1603 on 2019 December 01 02:53:47

I understand the recommended workflow for creating a SuperLUM is integrate each L R G B channels into respective masers and then integrate masters with no rejections

I usually use drizzle integration, so I am wondering how can I do to create a "drizzled SuperLUM"

Should I just align-drizzle the single Integrated masters and then drizzle integrate?

or align-drizzle all subs ?

thanks

Whether or not you drizzle, the process is the same: Create all the masters (with or without drizzle), and then integrate. Compare your superLum carefully to the Lum alone and use whichever you prefer.

Clear skies,

If you used drizzle on the RGB channels, then there is no need to do a second drizzle when creating the SuperLum.  It already has the drizzle applied to the underlying RGB channels and doing it a second time will add nothing.  If fact, you may be hurting your image since each time you star align you introduce artifacts.  You should only star align once for all subs.
