Managed to find 6 minutes worth of clear sky in the West, just after sunset. This is an RRGB image with the new TIS618 camera at 30fps R and G, 15fps B - most of the frames were too distorted to stack and the extra QE of the camera helped keep the noise level down a bit. thanks for looking. regards Ray
Thanks John - got lucky - we had an overcast day and a hole cleared at dusk, so the environment was pretty stable thermally. Jetstream was still there of course, but not much of the usual local instability and the air temp only dropped about 8C, so I could get the scope close to ambient in a fairly short time.
Hi Trevor, was pretty pleased when it stacked OK. Didn't expect seeing to be usable, but it was worth trying as it turned out. Will upload to PVOL when I work out how.
