Hi Brent thanks for the advise, I am tracking but admit I may not be 100% on the SCP. My Nikon is attached using the 2" thread. Light pollution out here is not an issue however smoke pollution can be during crop burn off.
Computer imaging software & expertise still haunt me as I am better in a darkroom than using this new digital technology, teaching an old dog

.
I've got 20 acres of land to use here but still haven't found a spot that's wind free when it blows so I may have to wait for calmer nights till I try again.
