Hey Mike,
I’m pleased you delivered on your promise to image this fascinating area… and a job well done too. You’ve captured some magnificent detail in the small arc surrounding R Coronae Australis. Shame about the two flood light flares as they detract from what is a great image. As you indicate (and it shows), you need more data before you can stretch out the faint wisps of dusty nebulosity – 30min lum is too lean for this area. It is a complex region to process. I know I used quite a few PS layers to manage intensity levels when I processed the region. Your image takes on a natural look which is pleasing to the eye.
So does this mark the first for the Astronomik 50mm LRGB filter set?
I can’t believe this is the first time you’ve taken flats

There’s a first time for everything I guess.
