Description

I have been struggling to gain more detail in supernova remnant SH2-224. I processed this a week or so ago with only two nights of data. I added about 12 hours more ha and oiii data over three more nights. When I stretch to reveal more faint areas, I end up with red and blue splotches and haze in and around the nebula. I tried both GHS and EZstretch  but ended up with similar results. To mitigate this, I used curves and PS contrast to bring down the dimmer regions. This isn't ideal and resulted in a very dark background. At least the mottling is gone.



If anyone has a process that can improve the stretch for fainter areas, let me know!
