A really good image of M8 with limited data , definitely not over saturated
Plenty of detail there although the core could be a touch brighter
Nice colours too
Looking at your PHD2 snap shot I noticed your guide star saturated ( Red SAT ) with a SNR of 138 . I’m surprised the guiding was so tight with a saturated star
My auto select guide stars normally have a SNR of 20 to 35
Do you manually select your guide star or use Auto select Star in Tools , I suspect you manually select as PHD2 wouldn’t select a saturated star
What scope for this image ??
