Thanks Raymo
Have you ever imaged in Sydney ( mega skyglow )
I took a 2.5 minute test exposure at ISO 800 and the RGB histogram curves ended up on the 2/3 line
The capture screen on BYEOS was like a white sheet
Dropped it down to ISO 400 and took a 2 minute test exposure , histogram curves ended up right on the 1/3 line and screen looked bright but within reason ( I knew Startools could wipe the gradients , vignetting and skyglow away )
You are spot on Raymo regarding the light gathering capability of the new 8” f5 compared to my old 6” f6 ( chalk and cheese )
I’m going to have to re think all my settings in the future for Sydney and at my dark site down the coast
Thanks
