Thanks Greg,
do you think longer exposures or more lights of the same exposures stacked?
I am thinking you're referring to more lights stacked. I agree, the more the better and as you said it's often challenging especially because i cant go at it every good clear night, I have to travel to the observatory basically on new Moons or sometimes weekends around it.
At least I've progressed to using flats and bias etc (Mike should be pleased
)
