Hi Alistair, Most of the Northern half of W.A. from the west coast to as
far east as about half way between Port Hedland and Broome has
250-300 clear nights per year. Further east from there you have a distinct
wet season, and get "only" about 150-175.
Last night I took some subs at 60, 75, and 90secs. I don't have an autoguider or OAG, and am too old to get myself into awkward positions to manually guide. Did that for 50+ yrs. I also have great difficulty with
the intricacies of PS etc. I have no idea how to work with gradients, layers etc; and do not take flats, biases, and let the camera take the darks. I am aware that I am fairly close to as good as I will get, and am happy to live with that.
