Exposure time

Recommended Posts

Hi All,

Hopefully I will be taking my QHY 163M on its first major trip to a dark site on the night of the 26/27th of June.  I plan on photographing M16.  I know that I will be able to shoot the target from 9pm to 4am.  Given that this will be my first time shooting LRGB, how do I divide the time between the different filters? Should they all be equal exposures (so about 100 minutes per filter) or are the some filters that require more data ?

Another side question, I live in a red light zone, is it worth shooting using LRGB? or is it not worth my time?

Thank you for your time and effort.
