A couple of weeks worth of progress on this target and surrounds.
Bahtinov mask is on and getting it done
More than one shot
. This is 57mins worth of 20sec at 1600 iso (with an f5 8" newt, heq5pro and stock 550D)
I'm getting there slowly with processing, but will spend some time tonight learning masking. I think there is more here but the keyhole is already a bit blown out, as is eta carina.
Anyway i might make this a yardstick of sorts, come back to it to guage progress.
